Title: An Analysis of Student Achievement Growth, Teacher Working Conditions and Qualifications, and School Choice Author(s): Marisa Cannata, Ph.D., Vanderbilt University Roberto V. Peñaloza, Vanderbilt University 2009 SREE Conference Abstract Template Abstract Body Limit 5 pages single spaced. Background/context: Description of prior research and/or its intellectual context and/or its policy context. As the most important resource for student learning, the academic success of any school depends on high quality teachers providing high quality instruction. Yet the impact of school choice on teachers and their work environments has received less attention than other components of school operations. Previous research points to observable differences in the qualifications of teachers in charter, magnet, and private schools compared to their colleagues in traditional public schools (Baker & Dickerson, 2006; Cannata, 2008). Additional work has explored the pay, personnel practices, and professional community of charter schools (Cannata, 2007; Goldring & Cravens, 2008; Harris, 2006; Podgursky, 2008). Less research has focused on the structure of teachers’ work inside various types of schools, their career decisions, and professional development. There are two key reasons for understanding both who teaches in various types of schools and what their work lives are like. First, increasing school choice creates options for teachers as well as students and the work environments created by different forms of schools can impact the overall teacher labor market. Second, teacher qualifications, professional development, and the structure of teaching inside schools have implications for the effectiveness of various school types and their impact on student learning. Schools of choice may increase their effectiveness by managing their human capital resources and organizing teachers’ work so that they can focus on instructional matters. Indeed, preliminary work on charter management organizations suggests that many charter management organizations use a human capital strategy to focus on student achievement (National Charter School Research Project, 2007). Purpose/objective/research question/focus of study: Description of what the research focused on and why. This paper explores the following question: How do variations in the work lives of teachers across charter, magnet, private, and traditional schools contribute to differences in student achievement across these school types? In doing so, this paper will focus on teacher qualifications, the amount and type of professional development in which they engage, their classroom contexts, the presence of barriers to their instruction, and teachers’ influence over school decisions. We hypothesize that fewer instructional barriers, more effective professional development, and greater influence over school decisions will be associated with higher student achievement in schools of choice. Utilizing data from teacher surveys, we examine the qualifications, professional development, and working conditions of teachers across school types. Previous research has highlighted the importance of teachers to student achievement, yet few teacher characteristics have been consistently linked to greater effectiveness (Goe, 2007). Part of this difficulty in establishing relationships between teacher characteristics and instructional effectiveness is due to a reliance on administrative data with few details on the organization, context, and ongoing 2009 SREE Conference Abstract Template 1 professional development that shape teachers’ instruction. The rich information about teachers’ work lives available in these data allow a more detailed examination of the components that lead to enhanced student outcomes. Further, a key argument for school choice is that giving greater flexibility to schools in staffing practices may lead to improved school outcomes (Podgursky, 2008). Thus exploring the extent to which the staffing practices of choice schools contributes to any observed differences in student achievement can help evaluate whether choice schools are meeting this ideal. Setting: Specific description of where the research took place. The data come from surveys of teachers in charter, magnet, private, and regular public schools. The schools are located in urban, suburban, and rural contexts across 24 states. The schools all participate in the Northwest Evaluation Association (NWEA) assessment program and student achievement data in mathematics, reading, and language usage come from NWEA assessments. NWEA administers state-aligned, computerized adaptive assessments in both the fall and spring of each academic year in reading, language usage, and mathematics. These assessments reference a single, cross-grade, and equal-interval scale developed using Item Response Theory methodology (Hambleton, 1989; Ingebo, 1997; Lord, 1980). The RIT scale is based on strong measurement theory, and is designed to measure student growth in achievement over time. NWEA research provides evidence that the scales have been extremely stable over twenty years (Kingsbury, 2003; Northwest Evaluation Association, 2002, 2003). Population/Participants/Subjects: Description of participants in the study: who (or what) how many, key features (or characteristics). The data come from a sample of 6,175 teachers in 283 schools, with a response rate of 74 percent. Surveys were collected from teachers in a sample of matched pairs of choice schools and regular public schools. All charter, magnet, and private schools in the NWEA were invited to participate in the study. Traditional public schools were matched to schools of choice based upon grade range, racial-ethnic and socioeconomic composition, initial achievement scores, and proximity. The final sample includes 115 charter schools, 33 magnet schools, 17 private schools, and 118 traditional public schools. Within these 283 schools our analyses focus on a student sample of over 20,000 students across all grade levels. Student achievement data come from the NWEA assessments in reading, language usage, and mathematics and also includes student demographic characteristics. The longitudinal nature of the achievement data allow for analyzing both achievement status and growth. 2009 SREE Conference Abstract Template 2 Intervention/Program/Practice: Specific description of the intervention, including what it was, how it was administered, and its duration. Charter, magnet, and private schools and traditional public schools; teacher qualifications, professional development, and work context as measured by a teacher survey Research Design: Description of research design (e.g., qualitative case study, quasi-experimental design, secondary analysis, analytic essay, randomized field trial). Statistical Survey, Quasi-experimental, Statistical Modeling Data Collection and Analysis: Description of plan for collecting and analyzing data, including description of data. Analyzing the effects of school choice requires accounting for problems of self-selection into choice schools (Hoxby & Murarka, 2008). Schools of choice may serve different types of students as families and students can self-select into them. Although our data do not permit analyses based on a randomized design (e.g., winners and losers of school lotteries), we have large enough samples and a number of observable characteristics to implement quasiexperimental designs relying on propensity score matching. We matched choice schools with regular public schools using several observables in administrative data before administering surveys. In addition, we examine how the in-school conditions in the different school types mediate the effects of school type on students’ achievement growth. We estimate a series of three-level, hierarchical linear models to estimate achievement growth nested within students, teachers, and schools (Raudenbush and Bryk, 2002; Singer and Willett, 2003). At level 1, student achievement (whether reading, language usage, or mathematics) is represented by an individual growth trajectory: ΔAchievementikj=π0kj+ π 1kj(Student Characteristics)ikj+ ε ikj where ΔAchievementikj is the observed achievement gains per month of student i between the fall and spring administrations in teacher k in school j (i.e., achievement score growth normalized over the time between test administrations); π0kj is the mean per month gain in achievement across students within teacher k and school j, conditioned on student background characteristics (i.e., race-ethnicity, gender, free/reduced lunch status, and grade level). We will assume a simple error structure for εikj, i.e., that it is independently and normally distributed with a mean of 0 and constant variance. We assume that the average achievement gains vary across teachers, represented by the following level-2 equations: π0j =β00kj+β01kj(Teacher Demographics) + β02kj(Teacher qualifications and assignment)ikj + β03kj(Teacher working conditions)ikj + β04kj(Professional development)ikj + r0ikj 2009 SREE Conference Abstract Template 3 where β00kj represents the mean achievement gain per month in teachers or classrooms within school j. Teachers’ demographics include race-ethnicity and gender. Teachers’ characteristics and assignment include years of experience, highest degree earned, experience working in another field prior to teaching, selectivity of undergraduate college, part-time assignment, permanent substitute teacher, and participation in TFA or similar program. Teacher working conditions include number of students taught, percentage of students with special needs, presence of resource shortages (alpha=.89), disengaged students (alpha=.86), teacher climate (alpha=.72), perception of student workload (alpha=.77), and teacher influence over school decisions (alpha=.85). Professional development measures include whether the professional development involves collective participation (alpha=.78), active learning (alpha=.88), reformoriented activities (alpha=.76), coherent (alpha=.87), and total hours of professional development in the subject assessed. In addition, we assume that the teacher or classroom gains in achievement vary across schools, represented by the following level-3 equations: β00kj =γ000+ γ001(School Type)kj + γ002(Other school-level characteristics)kj + u00j, where γ000 represents the mean achievement gain per month across schools. School type consists of dummy measures for charter, magnet, private compared with the matched traditional public schools. Other school characteristics include school demographics and other measures of school context. Findings/Results: Description of main findings with specific details. Preliminary results indicate that the characteristics, qualifications, and work contexts of teachers in charter and private schools have some differences from traditional public schools, while magnet school teachers and their contexts are more similar to traditional public schools. Charter school teachers have, on average, about half the years of experience as teachers in magnet, private, and traditional public schools and charter and private school teachers are less likely to have advanced degrees. Private school teachers are also less likely to have entered teaching from another career and more likely to have part-time appointments. Private school teachers appeared to have better working conditions as they reported fewer resource shortages, perceived the teacher climate and student disengagement was less of a barrier to their instruction, greater influence over school decision-making, and—with charter school teachers—reported instructing fewer students. Private and magnet school teachers perceived their student workload and students’ needs to be less of a barrier to their instruction. While teachers across all types of schools reported similar number of hours of professional development focused on math and reading/language arts instruction, the reported differing characteristics of this professional development. Charter school teachers reported more professional development in which they participated with their colleagues and more reformoriented professional development. Private school teachers participate in professional development that provides fewer opportunities for active learning and learning reform-oriented instruction. Given previous research on features of professional development that are associated with greater student learning (Garet et al, 2001), it would appear that charter school teachers 2009 SREE Conference Abstract Template 4 participate in somewhat more effective professional development and private school teachers participate in less effective professional development. Despite these observed differences in the qualifications, professional development, and work contexts of teachers across school types, few of these differences were related to student achievement gains. Compared to traditional public schools in models with grade level dummies only, achievement gains per month were larger in charter schools, with no differences for private or magnet schools. Consistent with prior research on teacher qualifications, few qualifications had a significant effect on student achievement gains. Teachers with educational specialist degree did have higher achievement gains in math and language usage than teachers with only a bachelor’s degree (see Table 1), although schools of choice did not vary on this qualification. Although there were differences in the work contexts of teachers across types of schools, these contexts were not significantly related to achievement gains. The exception was that having more limited English proficient students was associated with smaller math score gains and more influence over school decisions was associated with larger gains in language usage. Components of teacher professional development were not related to achievement gains in any subject. Conclusions: Description of conclusions and recommendations of author(s) based on findings and over study. (To support the theme of 2009 conference, authors are asked to describe how their conclusions and recommendations might inform one or more of the above noted decisions—curriculum, teaching and teaching quality, school organization, and education policy.) This study highlights the difficulty researchers have faced in identifying characteristics of effective teachers or indicators of teacher quality. Few characteristics of teachers, their assignments, or work contexts were related to student achievement gains. Teachers with educational specialist degrees did have higher student achievement gains in math and language usage, suggesting future research should explore explanations for this result. This study also suggests that efforts to increase or regulate teacher professional development requirements may not be an effective strategy for improving student outcomes. 2009 SREE Conference Abstract Template 5 Appendixes Not included in page count.
