This article examines the effectiveness of training facilitators in secondary schools to follow APA learner-centered principles to support learners in distance education. The study was a cluster-randomized control trial with 36 match pairs of schools and 246 students in the rural USA. The schools were selected at random and assigned at random to treatment condition. Instructors were blind to the treatment condition as were the local facilitators and schools. Data on length of time spent in the course and whether students completed the semester were analyzed. The results indicated that students in the intervention condition completed the first semester at a statistically higher rate than control students where facilitators did not have this training. The number of weeks students remained in the course was likewise statistically different with students in the intervention condition staying in the course more weeks holding instructor constant. Keywords: learner-centered distance education; facilitator training; student retention; rural education Introduction The use of distance education has been increasing dramatically in recent years. As in the past, the growth in distance education reflects the need for courses among students who are not able to participate in traditional face-to-face courses (Beldarrain, 2006). Bates (2005) documented the rise in distance education worldwide and traced the history of several distance education institutions including the British Open University, the University of Catalonia in Spain, Indira Gandhi National Open University in India, and the Instituto Tecnologico y de Estudios Superiores de Monterrey in Mexico to demonstrate both the growth and range of operations in distance education institutions worldwide. Although the greatest growth and use of online learning is at the tertiary level, the impact of distance education is also being felt in secondary schools. Among secondary school students, grades 9–12, in the USA 12% have taken a distance education course at their school and 8% have taken a distance education course on their own (Henke, 2008). Watson and Ryan (2007) reported that 42 of the 50 states in the USA now have significant online learning programs in their schools that are either supplemental to the regular face-to-face instruction or in which students take all, or almost all, of their courses online. These programs are also growing, with 40% of them reporting annual growth of over 25% (Watson & Ryan, 2007). *Corresponding author.

Hannum et al. Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 The incidence of distance education in high schools in rural areas of the USA is higher than the national average. Hannum et al. (2006) reported that 69.8% of rural districts are using distance education courses, most often in the form of online courses. Over 84.5% of rural schools had used distance education, and the majority indicated a need for additional distance education courses to meet their curriculum requirements. A recent report on distance education in the USA also indicated that the proportion of rural districts with students taking online courses is nearly twice that of urban and suburban districts (Setzer & Lewis, 2005). Because many rural schools are small, often they do not have enough students wanting to take a specific course to justify creating a class and assigning a teacher, and they have difficulty attracting teachers especially in certain subject areas. Distance education via the Internet has become an acceptable option in rural schools as a result of improvements in the necessary infrastructure, affordability of technology, and near universal connectivity (Hobbs, 2004; Jimerson, 2006; Malecki, 2003). Effectiveness of distance education Research supports that distance education in the form of online learning is at least as effective as traditional classes in terms of learning outcomes and often more effective (Bernard et al., 2004; Cavanaugh, 2001; Cavanaugh, Gillan, Kromrey, Hess, & Blomeyer, 2004; Cradler, McNabb, Freeman, & Burchett, 2002; Hobbs, 2004; Tallent-Runnels et al., 2006; Waxman, Lin, & Michko, 2003). In a meta-analysis of distance education studies, Zhao, Lei, Yan, Lai, and Tan (2005) reported an overall conclusion of equal effectiveness when all studies were taken into account but noted that in more recently published studies distance education was found to be more effective than face-to-face education. Although studies support the effectiveness of distance education when compared with traditional classroom instruction in terms of student achievement, students often fail to complete online courses. Some report that 50–70% of students do not complete online courses or programs (Carr, 2000; Roblyer, 2006; Rovai & Wighting, 2005; Simpson, 2004). Despite this being a recognized concomitant of online courses, little research has examined and tested factors that may improve course completion. The purpose of this article is to examine the initial effects of an intervention designed to increase secondary school students’ completion of an advanced online course by preparing local facilitators to support online learners. Distance education model A common model for distance education at the secondary school level features an instructor teaching at a distance from the students using some course management system to deliver an asynchronous online course. In the local schools, students who are taking the course have a regular class period assigned for the purpose of signing on and completing required course assignments. Several students may be in the same room during this class period although they can be taking different online courses. An adult facilitator who is responsible for insuring that everything is working smoothly and order is maintained usually monitors the students but does not teach the course. This approach differs from the more independent learning model in tertiary education in which students typically complete online courses working on their own without any teacher or facilitator physically present. The distance education model guiding this study holds that with proper training, a school-based facilitator can be a source of support necessary for secondary students’ success in online distance education courses. Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 Distance Education 213 Need for school-based facilitators Rural educators and policymakers have indicated that student support in distance education is vital and can include having school-based facilitators (e.g., Hobbs, 2004). A report by the US Department of Education (2007) found that school districts that are using online courses, as well as providers of these courses, indicate that the more support students receive at school, as well as online, the better chances they have for success. There are suggestions in the research that a school-based facilitator may be essential (e.g., Kirby & Driscoll, 1997) to student success. Smith, Clark, and Blomeyer (2005) indicated that pairing a highly qualified online instructor with a classroom aid in the local school can work at least as well as or ‘arguably better’ than traditional classroom instruction with a less qualified teacher (p. 68). Barr and Parrett (2001) indicated that having courses facilitated by competent, caring adults is important with at-risk students. Davis and Rose (2007) support the presence of trained onsite facilitators to coach and advocate for K-12 students in online courses. This confirms the role local facilitators can play in the success of distance education, even when they do not have the same qualifications as the online instructor. Student needs in distance education Kim (2004) identified the issue of time and self-pacing as playing a role in student attrition in distance education. Further, student motivation combined with these factors appears to be a primary contributor to attrition in distance education. Simpson (2004) concluded that retention rates have always been lower in distance education when compared with traditional education. He examined several interventions based on contacting students as well as the timing of interventions during the course to determine whether it was possible to reduce the oft reported dropout problem in distance education. Contact with students during the course increased the number of students completing courses. Passey (2000) cautioned that distance education courses should reflect the need to have strong social supports rather than an approach that lowers social interactions. In a study of students in the UK participating in an online Master of Education program, Motteram and Forrester (2005) found that students had concerns about managing their workloads, keeping up with readings, and maintaining sufficient motivation to be successful. Abel (2005) examined factors associated with success in Internet-supported learning in tertiary institutions and found that along with strong institutional commitment and motivation to be successful, the degree of support for faculty and students predicts success. He reported that students in successful programs were well supported including student orientation to online learning, a single point of contact for students, and frequent feedback to students. Students have reported less cohesiveness and involvement in their distance education courses than in traditional face-to-face courses (Hughes, McLeod, Brown, Maeda, & Choi, 2005). Studies have shown that motivation factors (e.g., self-efficacy, locus of control, risk taking, organization, and self-regulation) are important in distance education courses at the secondary level (Rice, 2006). Some have criticized distance education for its lack of personal contact (Frank, Reich, & Humphreys, 2003). Others have noted the sense of isolation students feel in distance education courses (Abrami & Bures, 1996). Support for learning is an element of effective pedagogy often missing in distance education courses (Bonk & Dennen, 1999; McCombs & Vakili, 2005). Distance education courses often fail to do this as a result of their very nature. Many distance education courses push content to learners via the Internet, but fail to provide students with necessary support for learning. Having someone physically present with the learner, who knows the learner and fully understands the local context of the learning, can be beneficial. Many distance 214 W.H. Hannum et al. Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 education courses ignore this human element. Likely this is why so many students drop out of distance education courses and rate them poorly. Important pieces essential for learning are missing, and students recognize this. Learner-centered view The starting point in a more learner-centered view is attention to empirically based knowledge about learners and learning to identify practices that will likely enhance the outcomes from distance learning. A set of such principles is embodied in the learnercentered psychological principles (LCPs) (APA Task Force on Psychology in Education, 1993; APA Work Group of the Board of Educational Affairs, 1997) that are based on a comprehensive review and analysis of the literature on learning. The LCPs consist of 14 principles based on theory and research that focuses on human thinking, learning, motivation, and social processes and on personal and interpersonal relationships, beliefs, and perceptions that are affected by and/or supported by the educational system as a whole. These research-validated LCPs provide a framework for designing distance education environments and practices that attend holistically and systemically to the needs of all learners. How the LCPs address learners and learning The 14 LCPs are organized into four categories, or domains: (1) cognitive/metacognitive factors, (2) motivational/affective factors, (3) developmental/social factors, and (4) individual difference factors. The 14 specific principles within these categories define much of what is known about learning and learners as a result of research into both. Many of these principles are consistent with recent discoveries from psychology relating to positive youth development and prevention interventions (Blum, McNeely, & Rinehart, 2002; Catalano, Haggerty, Oesterle, Flemming, & Hawkins, 2004; Libbey, 2004; Seligman & Csikszentmihalyi, 2000). These principles are robust, represent the best knowledge about human learning and development, and are applicable to all levels and types of school learning including distance education (Hannum & McCombs, 2008; McCombs & Vakili, 2005). The LCPs are shown in Table 1. Purpose This study sought to ascertain whether having an adult facilitator trained in applying LCPs to support secondary school students as they complete an online distance education course is an effective way to enhance the engagement of students and increase their rate of completion of an online course. The goal was to determine if preparing local facilitators in using LCPs would increase students’ progress in and completion of online distance education courses more than was possible if facilitators did not have this training. The null hypotheses were: H1: H2: There will be no differences in persistence in a distance education course measured in weeks between students whose facilitators were trained in applying LCPs and those whose facilitators did not have such training. There will be no differences in completion rates in a distance education course between students whose facilitators were trained in applying LCPs and those whose facilitators did not have such training. Distance Education Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 Table 1. 215 Learner-centered principles (McCombs, 2001, p. 187). Cognitive and metacognitive factors Principle 1: Nature of the learning process The learning of complex subject matter is most effective when it is an intentional process of constructing meaning from information and experience. Principle 2: Goals of the learning process The successful learner, over time and with support and instructional guidance, can create meaningful, coherent representations of knowledge. Principle 3: Construction of knowledge The successful learner can link new information with existing knowledge in meaningful ways. Principle 4: Strategic thinking The successful learner can create and use a repertoire of thinking and reasoning strategies to achieve complex learning goals Principle 5: Thinking about thinking Higher order strategies for selecting and monitoring mental operations facilitate creative and critical thinking. Principle 6: Context of learning Learning is influenced by environmental factors, including culture, technology, and instructional practices. Motivational and affective factors Principle 7: Motivational and emotional influences on learning What and how much is learned is influenced by the learner’s motivation. Motivation to learn, in turn, is influenced by the individual’s emotional states, beliefs, interests and goals, and habits of thinking. Principle 8: Intrinsic motivation to learn The learner’s creativity, higher order thinking, and natural curiosity all contribute to motivation to learn. Intrinsic motivation is stimulated by tasks of optimal novelty and difficulty, relevant to personal interests, and providing for personal choice and control. Principle 9: Effects of motivation on effort Acquisition of complex knowledge and skills requires extended learner effort and guided practice. Without learners’ motivation to learn, the willingness to exert this effort is unlikely without coercion. Developmental and social factors Principle 10: Developmental influence on learning As individuals develop, they encounter different opportunities and experience different constraints for learning. Learning is most effective when differential development within and across physical, intellectual, emotional, and social domains is taken into account. Principle 11: Social influences on learning Learning is influenced by social interactions, interpersonal relations, and communication with others. Individual differences factors Principle 12: Individual differences in learning Learners have different strategies, approaches, and capabilities for learning that are a function of prior experience and heredity. Principle 13: Learning and diversity Learning is most effective when differences in learners’ linguistic, cultural, and social backgrounds are taken into account. (continued) 216 Table 1. W.H. Hannum et al. (Continued). Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 Principle 14: Standards and assessment Setting appropriately high and challenging standards and assessing the learner and learning progress – including diagnostic, process, and outcome assessment – are integral parts of the learning process. Method This study was a cluster-randomized control trial. Specifically, schools were matched and then schools within each matched pair were randomly assigned to the intervention and control condition. Students took an Advanced Placement (AP) English Literature and Composition course that was taught by two instructors. This course was designed to teach the skills necessary to encounter and understand a broad range of literature and to prepare students for the AP English Literature and Composition exam. One focus was to expose students to a broad range of literature including short works and poems, a chronological survey of British literature, and novels that will challenge and edify readers. A second focus in the course was to develop composition skills that range from essays to original poetry to literary responses. The assignment of schools in each matched pair to control or intervention condition was done by random, then each matched pair of schools was assigned to one of the two course instructors in such a fashion as to balance the overall number of students each instructor had. This allowed control and intervention conditions to be nested within instructors. The students completed the course working during a regularly scheduled school period with a facilitator in the room with them. The study employed an experimental design because this is often the most powerful approach to determining if an intervention has an effect (Shadish, Cook, & Campbell, 2002). Yet, experimental designs have rarely been used in distance education research (Abrami & Bernard, 2006). Participants This study selected rural schools at random from all rural schools in the USA using the National Center for Educational Statistics (n.d.) database and following the Rural Education Achievement Program (US Department of Education, n.d.) definition of rural. Random selection of schools was undertaken to ensure a better representation of all rural schools and to ensure generalizability of results. Each school was paired with a similar school in terms of several demographic characteristics including proximity to each other, community and school size, similarity in terms of resources, and academic backgrounds of students. One school in each pair was assigned to the intervention condition and the other school was assigned to the control condition by a random process. Students took an AP English Literature and Composition course that was taught by two instructors. The design was double-blind in that the schools did not know which condition they were in, nor did the distance education instructors know which condition their students were in. The study consisted of 36 schools (18 match pairs) and a total of 246 students. In order to maximize sample size and power, an additional non-matched school that was in the control condition was also included in analyses. Although schools were matched on several characteristics, we conducted pre-intervention assessments within the content area using items from the AP English Literature and Composition examination that had been used in prior years. We limited instructor-related variability in the following ways. Each instructor taught one subject area course with separate class sections for intervention students and control students. This also reduced or eliminated Distance Education 217 Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 the possibility of students in different treatment conditions coming into contact with and interacting with each other during the study. Class sections were limited to approximately 20 students each. The instructors remained blind to the intervention status of their sections as did the facilitators and the schools. In addition, instructors kept logs of their contact with students and school personnel (i.e., facilitators and other school contacts). Role of facilitator The basic role of the facilitators was to support and guide students. Specifically, facilitators dealt with various issues such as troubleshooting computer problems, coordinating efforts with instructors and course administrators, monitoring student attendance, collecting some homework assignments, proctoring exams, and helping students with any scheduling questions or problems students feel they cannot discuss with the instructors. The role of the facilitator differed from that of the distance education instructor in several respects. Facilitators were physically present in the room with students when students were online during the scheduled daily period for students to be in the distance education class. The course instructors were not physically present and may or may not have been online or directly accessible during that time since the course was asynchronous. Instructors and students communicated through mediated means such as posting assignments, comments, and reflections through threaded discussion boards in the course platform software (e.g., Blackboard Academic Suite) and by email. An additional difference was that facilitators, unlike the course instructors, did not teach content. Indeed, facilitators were not expected to have the requisite knowledge or skills to do so. The instructors alone were responsible for course design and delivery of all content. Instructors may have asked facilitators to help check the completion of an assignment, but the facilitators did not teach the content. In this investigation, it was stipulated that facilitators need only be an adult employee of the school with a college education, not a teacher. Some facilitators who participated in the project were teachers. However, principals, secretaries, librarians, and teachers of other subjects or coaches also served in the facilitator role. Facilitator training intervention Facilitators in both conditions received basic training in the mechanics of using the distance education software as part of their standard training. Specifically, all facilitators received training on how to register students, how to assign/change passwords, how students can access the courses on the Web, how students handle the mechanics of uploading and downloading files, how to send postings in the discussion forum, and how to check student grades. The standard training provided facilitators with information about the basic or standard role of facilitators, which was to support and guide students by helping them with various problems. The training was delivered online via Blackboard Academic Suite and made available one week before the course began. In addition to this standard training, intervention facilitators were provided knowledge about LCPs and ways of applying these to deal with common issues students encounter in distance education. This was also accomplished by an online training which began a week before the course started. Following the overview of the LCPs, the training provided facilitators in the intervention group with scenarios depicting common issues and problems that arise for students in distance education. These scenarios were derived from our findings and experiences in a pilot study with rural students and schools. These were intended to provide facilitators a 218 W.H. Hannum et al. better idea of what to expect and how the LCPs may help them deal with these situations. The scenarios were provided over a period of several weeks starting before the course began and continued over the first few weeks of the class. The scenarios were delivered in a multiple media format that included text, audio clips, and images. Each scenario featured one or more students with a problem to which a model facilitator responded. These included the following issues and topics: ! Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 ! ! ! ! ! ! ! First day of school. This scenario presented strategies for introductions and icebreakers. The goal was to model the creation of an atmosphere that allows students to collaborate, problem solve, and openly discuss anything course-related. Discussing assignments. This scenario modeled a facilitator setting aside a class period in the first week of the year to go over course logistics. Facilitators were asked to encourage students to brainstorm strategies for specific problems relating to technology, grades, and feeling overwhelmed or confused over an assignment. Student fears. This scenario depicted a reluctant student having a conversation with the facilitator concerning the student’s fears about the course. The facilitator modeled some strategies that might be used for dealing with such issues. Time management. This scenario featured a student who tended to procrastinate and is discussing this with the facilitator. The facilitator covered a number of strategies for effectively organizing the workload. Helping students help themselves. This scenario was designed to encourage students to interact with their online peers. Too much work. In this scenario, a student is overwhelmed by the workload and is far less confident than he/she initially appeared and believed. The facilitator modeled several strategies that address these issues. Disengaged. A student who was at the top of the class during the first weeks of the course but later had falling grades and seemed increasingly disengaged was portrayed in this scenario. The facilitator discussed this with the student to find out more about where the student was having difficulties and what may have been the source. Worries about grades. In this scenario a student was considering dropping the course because of concerns about the grade in the online course being lower than grades in other courses and the adverse affect on his/her grade point average. The student was also having difficulties managing the workload. The facilitator attempted to allay the student’s anxieties by discussing college expectations and the benefits of taking challenging courses. Intervention facilitators were provided an online discussion board related to each scenario and were asked to post their comments about the scenario, which LCPs they believed were evident, what they thought the LCPs suggested could be done in the situation, and any comments about other facilitators’ postings. The intervention was also designed to form a community of support among intervention facilitators. Intervention facilitators were informed that the discussion board was where they could post questions to other facilitators and use this to support each other. The attempt to form a community among the intervention facilitators was intended to provide the professional support and collegial interaction they may have been accustomed to from their experience in small rural schools. The community of intervention facilitators was also intended to be a resource – a group of individuals who were experiencing similar issues, and with whom facilitators might be more apt to identify. Given that this was for many a new role and context, having this support and awareness among facilitators may Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 Distance Education 219 have been reassuring. In addition, facilitators may draw on each other to solve problems or resolve issues they may encounter. Control facilitators also had access to a discussion board that they could use as needed. However, control facilitators were not provided the overview of the LCPs, scenarios, or directed to discussion boards to discuss the scenarios or to form a community with other facilitators. Another key feature of the intervention was the use of data to provide feedback to and professional development for facilitators in the intervention condition during the semester. Specifically, students and facilitators completed rating scales assessing relevant LCPs and related factors including beliefs about learning, motivation, class experiences, and facilitator support. The results of this survey were aggregated at the classroom level and provided to intervention facilitators. Members of the project staff then conducted brief feedback sessions over the telephone with intervention facilitators to discuss and interpret the results. A main focus of the survey and feedback session was how students perceived their distance education setting in terms of several LCPs and related factors. In addition, the implications from these results and suggested steps facilitators in the intervention condition might have taken were provided. Outcome measures There were two principal outcomes of interest in this investigation. The first was the length of time that students stayed in the online course. The second outcome variable was whether students stayed in the course or dropped out at some time during the course. Length of course participation The length of students’ participation in the online course was measured in the number of weeks. Facilitators were directed in several written documents and communications to inform research staff when a student decided to no longer continue in the course as soon as this decision had been reached. Research staff documented the date when any student decided to withdraw. The length of course participation was calculated as the number of weeks students were in the online course and this included the week the decision to no longer continue was made. Dropout The next principal outcome variable was student dropout. This was a dummy coded variable with students who dropped out of the course receiving a value of 1 and those who did not receiving a value of 0. Covariate measures Several baseline or pretest covariates were obtained. These included several self-report measures of facilitators’ beliefs and reflective self-awareness. Students also completed measures of their prior course-related achievement and several self-report motivation scales. In addition, a variable representing instructors was included. Facilitator beliefs and reflective self-awareness Information regarding facilitators’ beliefs and reflective self-awareness was measured by several subscales and adapted from the assessment of learner-centered practices (ALCP) Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 220 W.H. Hannum et al. battery (McCombs & Lauer, 1997). The ALCP consists of several surveys developed to help teachers identify students’ needs and changes in areas of instruction that can meet these needs. The original ALCP battery included surveys for teachers, students, and administrators. The ALCP surveys have been validated with more than 5000 K-20 teachers and more than 25,000 students taught by those teachers. Different versions have been validated for grades K-3, 4–8, 9–12, and college (McCombs, 2003; McCombs & Lauer, 1997). For the secondary school level, the ALCP battery assesses four domains of classroom practice that are most predictive of student motivation and achievement (i.e., establishing positive relationships and classroom climate, providing motivational support for learning, facilitating students’ learning and thinking skills, and honoring student voice and providing individual choice and challenge). The secondary teacher survey also includes several measures of the following beliefs: teachers can influence adolescents’ learning (Can influence difficult stages) or cannot impact adolescent learning (Difficult stage), teachers can best support learning by a moderate degree of control (Moderately controlling) or a high level of control (Highly controlling), and teachers can best support learning by providing a moderate level of student choice and control (Moderately autonomy supportive) or a high level (Highly autonomy supportive). In addition, the reflective self-awareness subscale assesses the degree to which teachers are aware of the influence of thoughts and feelings on actions and tend to analyze and reflect on relevant experiences. For this investigation, the secondary teacher scales assessing beliefs and reflective selfawareness were modified by changing the point of view and wording from that of a teacher to that of a facilitator. These adapted measures were administered via an online survey. Facilitators completed the survey as their first activity and immediately before starting to go through the appropriate training materials. The measures of classroom practice were likewise modified but were not administered at baseline because the course was not yet underway. Student motivation The student measures of the ALCP battery also contained several scales that assess different dimensions of student motivation. These included beliefs in learning competency (selfefficacy), knowledge-seeking learning curiosity (state epistemic curiosity), use of actively engaged learning strategies (active learning strategies), use of learning strategies that avoid effort (effort avoidance strategies), intrinsic motivation and mastering goals (task mastery goals), extrinsic motivation and achievement-driven goals (performance oriented goals), and motivation to avoid work (work avoidance goals). Students completed these scales via an online survey at the start of the course as a baseline measure of their motivation. The student ALCP battery also contained several measures of the same classroom practices teachers or facilitators completed and were likewise modified but were not administered at baseline. Student achievement Prior student course-related achievement was measured with a previous multiple-choice portion of an AP English Literature and Composition exam from a set of such exams instructors are provided by the College Board (n.d.). Students completed the exam early in the course over two days (i.e., the fourth and fifth days of academic instruction). The exam was online and embedded in the course platform. In addition, students were given a time limit each day for taking and having access to the exam. Instructors were able to do this through the features of the course platform and this was done to control the amount of time students had to take the exam as well as to simulate more realistic testing conditions. Distance Education 221 Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 Instructor Two instructors taught all sections of the online course. In order to explore and control for possible instructor effects, a dummy coded variable representing one of the two instructors was included in analyses. Analysis plan The purpose of the study was to determine if there was any treatment effect on the length of time students persisted in a distance education course (hypothesis 1) and whether they completed the first semester (hypothesis 2). Due to the multilevel structure of the data, that is, students were nested within schools (or facilitators), a two-level unconditional model with random intercept (model 1) was first run using the SAS MIXED procedure to estimate the amount of explainable variance at each level (Raudenbush & Bryk, 2002; Snijders & Bosker, 1999). Based on experimenter observations instructor and treatment appeared to have an effect on length of participation, dummy coded instructor and treatment variables were entered at level 2 to explain school level variance. To explore significant covariates for each level, stepwise ordinary least squares regression was used to liberally select predictors (among group mean centered level 1 student motivation scales and achievement pretest scores as well as grand mean centered level 2 average school achievement pretest and student motivation scores and facilitator scale scores) that were significant at the 0.25 level. The selected and potentially helpful covariates were entered into the two-level mixed model to obtain more precise effect and standard error estimates (model 2). Statistically nonsignificant predictors at the 0.05 level were removed from the model (model 3). The last model (model 4) was the most parsimonious, and retained only significant predictors at the 0.05 level. For all mixed model estimations, the restricted maximum likelihood (REML) estimation method, model-based fixed effects standard error method, and between–within degrees of freedom method were requested (Kreft & de Leeuw, 1998). To explain dropout from the study, similar analytical strategies were followed. Because the outcome measure was dichotomous (1 = dropout during semester; 0 = remained in the study at the end of semester), stepwise logistic regression was used to select significant covariates (at the 0.05 level) instead. Moreover, generalized linear mixed models (the SAS GLIMMIX procedure) were used to take into account the multilevel data structure in estimating the predictor effects. Because dropout status at the end of the semester and length of participation contain essentially the same information, results from the two modeling approaches are expected to be similar. Results The purpose of this study was to determine if training local facilitators in supporting online learners would increase the rate at which they persisted in and completed an online course. The principal finding was that students who had facilitators trained in a learner-centered approach to provide support for students stayed in an online course more weeks and completed the course at a higher rate than a control group who had facilitators without this training. Table 2 summarizes the internal consistency reliabilities for student and facilitator self-report scales. Appendix 1 presents the fixed and random effect estimates on length of course participation. There was a statistically significant amount of variation in average length of participation across schools (estimated level-2 variance = 23.82, p < 0.01). After adding the school 222 Table 2. W.H.

Among the predictors entered in the second model, only the treatment, instructor, and facilitator beliefs that adolescence is a difficult stage were statistically significant at the 0.05 level. After removing all the nonsignificant predictors from the model, treatment and instructor effects remained statistically significant but the difficult stage facilitator variable became nonsignificant in model 3. These three predictors accounted for about 39% of the school level variance. After further removing the nonsignifcant difficult stage facilitator variable in the fourth model, both treatment and instructor effects remained statistically significant and they account for about 33% of the school level variance in length of participation in the first semester. Controlling for instructor difference, students in experimental schools on average remained in the study 4.69 weeks longer than students in control schools. Thus, hypothesis 1, which stated that there will be no differences in persistence in a distance education course measured in weeks between students whose facilitators were trained in applying LCPs and those whose facilitators did not have such training, was rejected. Students whose facilitators had training in applying LCPs remained in the course more weeks. Student within school variance was large and practically unexplained by the school level predictors. Appendix 2 shows the fixed and random effect estimates on dropout. Among the set of predictors selected by logistic regression and entered in the first model, only treatment, instructor, and facilitator beliefs that can influence difficult stages were statistically significant at the 0.05 level. These variables remained significant after removing the nonsignificant predictors from the second model. Because the measure of facilitator beliefs that can influence difficult stages was not very reliable (coefficient alpha = 0.48), it was removed from the third model to see whether the effects of treatment and instructor were affected. Treatment and instructor effects were statistically significant at the 0.05 level with (model 2) or without the facilitator beliefs that can influence difficult stages covariate (model 3). As expected, the odds of dropping out for students in the control schools were higher (about exp(2) = 7.39 times) than the odds for students in the experimental schools, holding instructor constant. Thus, hypothesis 2, which stated that there will be no differences in completion rates in a distance education course between students whose facilitators were trained in applying LCPs and those whose facilitators did not have such training, was rejected. Students whose facilitators had training in applying LCPs completed the course more often than students whose facilitators did not have this training. Distance Education 223 Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 In summary, regardless of whether length of participation or dropout was analyzed, treatment and instructor effects were statistically significant. Of particular interest in this study was the treatment effect. Holding instructor constant, students in the treatment condition were more likely to persevere through the difficult AP course in the first semester than students who were not. The difference in average length of participation was nontrivial (about four weeks). Limitations This study is limited by the population studied, that is, rural secondary schools in the USA. Generalizing beyond this population is not appropriate. The study is limited by the specific course taught, that is, AP English Literature and Composition. It is possible that the findings are unique to this course and that different results would be found for other courses such as mathematics, science, or foreign language. The two course instructors had experience teaching this course online, but it is possible that the impact of the facilitator training may differ in courses in which the instructors have more or less experience. The study is limited to distance education models that have local facilitators physically present with students. Generalizing to situations in which students work independently without a facilitator present is not appropriate. This study focused on training local facilitators to support students using a more learner-centered approach. Different results may be found if such training in learner-centered approaches was given to distance education instructors rather than facilitators. This is the first time the facilitator training program was developed and used. The outcomes may be different during subsequent uses of the training program. Students in rural secondary schools typically have good IT skills (Hannum et al., 2006). Results of this study may have been different if students did not have good IT skills and thus experienced difficulty using the technology. The data used in this study were collected over a one semester time period. The outcomes may be different for longer time periods. Conclusion and discussion Research indicates that student learning in distance education courses is at least equal to that in traditional classes if not better; however, distance education courses often have substantially lower rates of course completion. The purpose of this study was to explore the initial efficacy of providing training to school-based facilitators in following more learnercentered practices to support secondary students taking an online course and determine the impact on students’ persistence. Specifically, this study used a cluster-randomized control trial to investigate the effectiveness of an intervention to improve students’ first semester retention in and completion of a distance education course. The results indicated that students in the intervention condition, where their facilitators were trained to follow a more learner-centered approach to supporting students, completed the first semester at a statistically higher rate than did students in the control condition, where the facilitators did not have this training. A similar measure to first semester retention, the number of weeks in the course, was likewise statistically different with students in the intervention condition staying in the course more weeks. This research extended previous work on distance education by applying a randomized control trial to investigate the impact of having trained facilitators support students taking a distance education course. This intervention was based on the empirically validated LCPs that had been shown to exert influence on learning in traditional face-to-face courses but had not been used in distance education courses. Rather than comparing a distance education Downloaded By: [Hannum, Wallace H.] At: 16:29 27 September 2008 224 W.H. Hannum et al. course with a traditional face-to-face course as has been done in so much research, this study sought to explore different treatments within a distance education course that might have promise for improving course completion rates. This follows the recommendations of researchers such as Joy and Garcia (2000); Larreamendy-Joerns and Leinhardt (2006); Lockee, Moore, and Burton (2001); and Lou, Bernard, and Abrami (2006). Furthermore, this study followed the suggestions of Lou et al. (2006) by controlling for any potential instructor effects, differences in instructional materials, and time on task. Results indicated a significant difference in terms of student persistence when local course facilitators were trained in use of the LCPs. The dropout rate for students in the control condition (57%) in which their facilitators were not trained in using a learnercentered approach was within the range other researchers have reported (Carr, 2000; Roblyer, 2006; Rovai & Wighting, 2005; Simpson, 2004). However, the dropout rates of students in the intervention condition (34%) whose facilitators were trained in using a learner-centered approach was significantly less. Subsequent research should seek to explore the use of learner-centered approaches in distance education courses, especially by examining how the interactions among facilitators and students may differ when the facilitators have been trained in the use of such an approach. Examining student perceptions of the different ways facilitators can support their learning could be interesting as could exploring the impact of a more learner-centered approach on student achievement as an outcome and potential intervening variable. This research should also explore the use of learner-centered approach with a broader range of students, not just rural secondary students who are taking AP courses. The intervention in this study was aimed at local facilitators to enable them to support online learners by applying learner-centered approaches. Students and facilitators had faceto-face contact on a regular basis during this course. This contact may have been an important component of the intervention that could not be accomplished as well at a distance. An alternative approach would be to train the course instructors in applying learner-centered approaches as part of their online teaching and see if this would have a similar impact on student persistence and completion of the course. Based on the results of this study, we suggest that having facilitators in the room with secondary school students as they work on distance education courses can have a positive impact on the students’ persistence in these courses and their completion of the courses. The facilitators do not have to be teachers or familiar with the course content, as they do not have any responsibilities for conveying course content. Rather their role is to help students with their self-management, motivation, and other specific problems that students may encounter. The facilitator can also serve as the eyes and ears for distance education instructors who are not physically present by passing information back to the instructors when students encounter problems and stumble. Students taking AP courses through distance education may experience more problems due to the demanding nature of AP courses. Having trained local facilitators may be a way to alleviate or mitigate some of the issues students face in AP courses, such as the higher workload and the more demanding nature of AP courses. We believe that it is important to provide training for facilitators in LCPs of supporting students in order to have benefits such as those found in this research. This study found support for the position of Davis and Rose (2007) that professional development is necessary for onsite facilitators to enable them to play a successful role in coaching and supporting students taking online courses. When the training is based on helping facilitators use LCPs to support students, those students who have facilitators with this training persist longer and are less likely to drop out of online courses. Thus, we suggest facilitator training should center on how to apply learner-centered approaches to support students taking online courses.
