RESEARCH SECTION Co-operative learning for students with difficulties in learning: a description of models and guidelines for implementation Ellen Murphy, Ian M. Grey and Rita Honan As part of a larger study regarding the inclusion of children with disabilities in mainstream classroom settings, Ellen Murphy, of the D Clin Psych programme at NUI Galway, with Ian Grey and Rita Honan, from Trinity College, Dublin, reviewed existing literature on co-operative learning in the classroom. In this article, they identify four models of co-operative learning and specify the various components characteristic of each model. They review recent studies on co-operative learning with the aim of determining effectiveness. These studies generally indicate that co-operative learning appears to be more effective when assessed on measures of social engagement rather than academic performance. Finally, Ellen Murphy, Ian Grey and Rita Honan present their account of the factors that contribute to the successful implementation of co-operative learning for students with difficulties in learning. Key words: co-operative learning, grouping, special educational needs, inclusion. Introduction The inclusion of students with intellectual disabilities into regular classrooms continues to be a priority among teachers, administrators, policy makers and families (Dugan, Kamps Leonard, Watkins, Rheninberger & Stackhaus, 1995; McMaster & Fuchs, 2002). Within special education circles, co-operative learning is one of the most frequently recommended strategies for effecting the inclusion of students with disabilities in regular education classrooms (Jenkins & O’Connor, 2003). Co-operative learning is a peer-mediated, instructional arrangement: ‘in which small groups or teams of students work together to achieve team success in a manner that promotes the students’ responsibility for their own learning as well as the learning of others.’ (Mercer & Mercer, 1998, p. 35) It can be classified as a multi-element academic and social intervention which primarily focuses on arranging antecedent conditions to set the occasion for positive social interactions and tapping into natural contingencies of © NASEN 2005 reinforcement on completion of task (Madden & Slavin, 1983). Specifically, the use of co-operative learning incorporates elements of contingency management and social skills training while concurrently providing children with the opportunity to develop and practise their social skills in a naturalistic setting (Nixon, 1999). Rationale There are a multitude of reasons for employing co-operative learning as an inclusion strategy. A major challenge for teachers in heterogeneous classrooms is to engage all of their students in high quality learning activities. By replacing individual assignments, in which students have to work on their own, with assignments for small, heterogeneous groups organised according to co-operative learning steps, they would provide a more accommodating learning environment for students who are experiencing difficulties (Jenkins & O’Connor, 2003). Co-operative learning is enhanced by the possibilities it offers for achieving multiple educational goals. With its dual emphasis on academic and interpersonal skills (Johnson & Johnson, 1994), it appeals to teachers because it addresses diverse educational goals within a single approach (Antil, Jenkins, Wayne & Vadasy, 1998). Contemporary ideas on the nature of human learning also contribute to co-operative learning’s appeal. Learning was, for a long time, conceptualised as transmission of knowledge from expert to novice. This approach began to yield to a different paradigm which emphasised the social construction of knowledge (Vygotsky, 1978). Research into co-operative learning within Vygotsky’s theory considers that children are introduced to new patterns of thought and new understandings by engaging in dialogue with their peers (Jenkins & O’Connor, 2003). Overview of co-operative learning procedures The literature suggests that there are four main approaches to co-operative learning which include: the conceptual approach; the structural approach; the student team learning approach; and the curricular approach (Putman, 1998). Merely placing students with disabilities into groups with their peers does not ensure that they will interact in socially appropriate and instructionally beneficial ways (McMaster & Fuchs, 2002). However, if the essential components of co-operative learning are implemented, successful interaction is more likely. The contents of the models do not differ British Journal of Special Education • Volume 32 • Number 3 • 2005 157 widely; however, each model emphasises different elements as being essential (Johnson & Johnson, 1994; Slavin, 1995; Kagan, 1990). Conceptual approach The conceptual approach or learning together model (Johnson & Johnson, 1994) is a five-element standard model developed by Johnson and Johnson. It is conceptually based and is not tied to a specific curriculum or subject area. As this model is one of the more popular and basic models of co-operative learning, it is described in some detail here. The critical components proposed are: positive interdependence, individual accountability, face-to-face interaction, co-operative skill training and group processing (Putman, 1998). According to Johnson and Johnson (1994), the first step to structuring positive interdependence is requiring that students work together to attain a shared goal. This is known as ‘goal interdependence’. A group goal can be established in three ways. The goal for all members could be to produce one product, for example, to complete a worksheet successfully; to score above the criteria specified when tested individually; and/or to improve their performance over their previous average score. The second step in creating positive interdependence is to supplement positive goal interdependence with other types of positive interdependence such as reward interdependence, whereby members are rewarded as a group for successfully completing a joint task; role interdependence, whereby members are assigned complementary and interconnected roles; resource interdependence, whereby each member has only a portion of the information, materials or resources necessary for the task to be completed; and identity interdependence, in which the group establishes a mutual identity through a name or group symbol (Putman, 1998; Nixon, 1999; Johnson & Johnson, 1994). A number of common ways to structure individual accountability are also specified, including keeping the size of the group small, giving random oral examinations to students and having students teach what they have learnt to someone else (Johnson & Johnson, 1994). The third element, face-to-face promotive interaction, exists when individuals encourage each other in their efforts to complete the overall group goal. This can be encouraged by setting tasks which are conducive to this type of interaction and by monitoring the group and praising instances of promotive interaction. The fourth element, interpersonal and small group skills, involves children being taught the social skills necessary to work effectively in a group situation. According to Piercy, Wilton and Townsend (2002), a number of co-operative learning skills should be taught to group participants. These include: working together, sharing things, helping each other, talking politely to each other, checking that others understood and checking that others agreed. The final and fifth element of the model is group processing. This occurs when ‘groups reflect on their collaborative efforts and decide on ways to improve effectiveness’ (Antil et al., 1998). The process involves 158 the teacher and students reflecting at the end of a group session to decide which member actions were helpful and unhelpful and to make decisions about which actions to continue or change. An evaluation form to be completed by the group is a useful way of aiding group processing (Nixon, 1999). Structural approach The structural approach to co-operative learning was developed by Kagan (1990). A structure is defined as ‘a content independent way of organising social interaction in the classroom’ (Putman, 1998). Kagan’s model contains four basic principles symbolised by the acronym PIES: Positive interdependence, Individual accountability, Equal participation and Simultaneous interaction. Equal participation directs teachers to give every student an opportunity to contribute. Simultaneous interaction encourages teachers actively to involve as many students as possible at any one moment. One of the structures Kagan advocates is the ‘timed pair share’ structure. In this exercise, the students work in pairs. Within each pair, student A shares his or her thoughts with student B for one minute while student B listens and then the procedure is reversed. This structure contains all the elements outlined above. According to Kagan (1998), this is as easy to implement as a simple pair discussion. However, a simple pair discussion does not necessarily require children to divide their time equally, for example. Therefore the results of the ‘timed pair share’ are better. Student team learning method The student team learning method was developed by Slavin (1995) and is incorporated in more than half of all published studies of co-operative learning. This method involves creating a number of teams who then compete against each other. Essentially the method emphasises the use of team goals and team success. Three concepts are essential to all student team learning methods: team rewards, individual accountability and equal opportunities for success. Teams can earn team rewards if they achieve abo ve a designated and agreed criterion. Individual accountability requires that all individuals must contribute to the team for it to be successful. Equal opportunities for success means that students contribute to their teams by improving on their previous performance (Slavin, 1995). Student teams achievement divisions (STAD), teams-games-tournaments (TGT) and ‘Jigsaw II’ are the three most common forms of student team learning methods. STAD is considered to be the simplest form and consists of a four-step cycle: class presentation, teamwork, individual assessment and team recognition (Putman, 1997). TGT has many of the same dynamics as STAD. However, instead of individual assessment of students, the assessment is based on team competition using academic games (Putman, 1997). Finally, Jigsaw II is a structure generally only appropriate for working with written or nar rative material. One member from each team is required to become an expert on a certain topic. The experts from the different teams meet up to discuss what they have learnt. They then return to their original team and teach what they have learnt to their team-mates. Finally there is a quiz on all of the topics (Slavin, 1995; Putman, 1997). British Journal of Special Education • Volume 32 • Number 3 • 2005 © NASEN 2005 Curricular approach The curricular approach was also developed by Slavin and c o l l e agues. While the ap p ro a ches to afo re m e n t i o n e d co-operative learning formats can be adapted to most subject areas and grade levels, curriculum-specific co-operative approaches to support instruction in the classroom have also been developed (Putman, 1998; 1997; Slavin, 1995). Team-assisted individualisation (TAI) and co-operative integrated reading and composition (CIRC) are two such curriculum-based approaches. TAI focuses on mathematics for grades 2 to 8 (ages seven to 12). Students use self-instructional materials designed to help whatever individual skill level they are at. Team-mates check each others’ work using answer sheets and help one another with any problems. If a student fails to achieve an 80% success rate, the teacher intervenes to provide the necessary individual instruction. CIRC is a programme for teaching reading and writing in the upper elementary and middle grades. Reading books that would be used in traditional teaching are used. This method involves the use of teacher instruction, team practice, team pre-assessments and quizzes. The co-operative learning approaches formats as outlined above are those most widely used and well researched. Despite their variations, two elements in particular form the central components of all models. These are positive interdependence – that is, students working together to attain a shared goal (Nixon, 1999) – and individual accountability – that is, ‘the performance of each individual is assessed and the results given back to the individual and the group’ (Johnson & Johnson, 1994). Efficacy and evaluation of co-operative learning While recent empirical studies describe efficacy and evaluation procedures in some detail, they generally do not give information on the type of co-operative learning intervention used or details regarding the implementation of the intervention. The reviews evaluating the benefits of co-operative learning for students with learning difficulties appear primarily to be reviews of academic benefits. Thus far, these reviews have produced inconclusive results. More than ten years ago, Tateyama-Sniezek (1990) conducted a review of the literature and reported that half of the relevant studies reported significant effects. More recently, McMaster and Fuchs (2002) again reported mixed academic achievement outcomes resulting from co-operative learning interventions. These two reviews looked in some depth at the results of certain individual empiricial studies and there is no need to revisit that material in detail here. As outlined previously, however, these reviews, which elicited many debates on the success of co-operative learning, refer only to the academic benefits of co-operative learning based on a specific evaluation method – that is, formal academic testing procedures. Other evaluation methods have provided more promising results in terms of academic and social functioning. This article will now focus on the detailed review of the results of studies that used these altern at ive approaches to evaluation. Researchers may have begun to recognise that © NASEN 2005 social validity is as important as the academic validity in such studies (Koegel, Koegel & Dunlap, 2001). Evaluation through observation, teacher interview, peer acceptance measures and interviews with target children are the most frequent evaluation methods used in recent studies. Studies evaluating the effects of co-operative learning usually use a combination of one or more of the above as part of their evaluation procedure. Observation method A common evaluation approach in co-operative learning studies is the observation method. O’Connor and Jenkins (1996) assessed the quality of participation of special needs students in co-operative learning programmes over a two-year period using an observation evaluation method. They assessed the types of activities target children engaged in; the amount and kind of help they received; and the amounts and kinds of contributions they made to group efforts. The data were analysed by identifying patterns and themes within the observers’ notes. According to these authors, only 40% of students were successfully participating in co-operative groups. The authors noted, however, that differences in classroom practice appeared to be related to whether co-operative learning was successful or not. Four other studies (Piercy et al., 2002; Nixon, 1999; Dugan et al., 1995; Kamps, Leonard, Potucek & Harell-Garrison, 1989) have also used observation methodology. These studies used pre-test and post-test measures of social and academic engagement to evaluate the effectiveness of co-operative learning. Social and academic engagement were defined at the outset of the interventions and these behaviours were then recorded as being present or absent during intervals of a set time duration. These four studies found that the social and academic engagement levels of children with learning difficulties significantly increased after the implementation of co-operative learning interventions across various areas of the curriculum. Dugan et al. (1995) used pre-test and post-test observation procedures to evaluate both social and academic engagement levels within an overall ABAB design. The participants were two children with autism aged nine and ten years and 16 typically developing peers. The intervention lasted 12 weeks in duration. The observation procedure for measuring academic engagement involved two researchers observing engagement in two ten-minute samples during 40-minute class periods. Behaviours were classified as engagement behaviours, non-engagement behaviours or other behaviours. The following behaviours were considered to be active academic engagement behaviours: writing, task participation, reading aloud, reading silently, talking about academic material, answering questions and asking questions. Social interaction was observed in five-minute samples for the target child and their corresponding peer a minimum of once per week during class periods, during baseline conditions and during co-operative learning sessions. Initiations, responses and the lengths of interactions were recorded. Initiations were defined as motor or vocal British Journal of Special Education • Volume 32 • Number 3 • 2005 159 behaviour clearly directed to a peer that attempted to evoke a response. Responses were defined as motor or vocal behaviours given in response to an initiation within three seconds. These authors found positive increases in both academic and social engagement. Their findings replicated the findings of Kamps et al. (1989) who also examined social and academic participation using a similar observation pre-test and post-test procedure within an ABAB design. These participants consisted of one child with autism aged eight and 15 typically developing children of a similar age. Significant increases in social and academic engagement were again found. Piercy et al. (2002) also used a pre-test and post-test observation procedure but, in this study, social engagement alone was measured. The participants were six children with learning disabilities and 45 typically developing children and the intervention lasted ten weeks. The frequency with which the target child engaged in positive social interaction behaviours both before and after the implementation of a co-operative learning programme was recorded. In contrast with Dugan et al.’s (1995) study, behaviour was not actually observed during class periods. Behaviour was observed during a one-hour free choice activity session prior to the co-operative intervention and again in a one-hour free choice activity session after the co-operative intervention was implemented. Each child was observed for ten minutes in total within that one hour. An alternating observation procedure was used whereby a child was observed for 30 seconds and this continued until all six children had been observed. The observer then reverted back to observing the first child again. An increase in the frequency of social behaviours was observed. Nixon (1999) also partly evaluated a multiple component intervention consisting of a token economy system, social skills training and a co-operative learning programme for three children with ADHD in an Irish primary school using an observation evaluation method. The intervention lasted six to eight weeks. The author observed two types of behaviour: task orientation behaviours and social behaviours. Two observers recorded whether each target child was engaged in on-task or off-task behaviour and the nature of the social interaction that the child was involved in: positive, neutral, negative or no interaction. The observers recorded data throughout the entire duration of baseline and co-operative learning sessions. A multiple baseline design was incorporated within the study. An increase in both social and task orientation behaviours was found. Results suggest that this evaluation method has consistently demonstrated positive results. Along with using an observation evaluation procedure, two of these studies (Kamps et al., 1989; Dugan et al., 1995) also measured academic performance using formal academic tests. These demonstrated that academic performance also increased after the co-operative learning intervention. The ambiguity in results in the area of formal academic testing could originate in differences in implementation of the original co-operative learning programme. 160 Peer acceptance method Examining peer acceptance of students with learning difficulties both before and after a co-operative learning intervention is another evaluation method which has been frequently used. Along with evaluating the co-operative learning programme using observation, Nixon (1999) evaluated her programme using peer acceptance measures. Analysis of pre-test and post-test interviews revealed that, while the intervention failed to produce significant changes in peer perceptions of target children, it did produce positive changes in peer perceptions of children in general in the classroom (both typically developing peers and target children). Nixon argued that it may have been the short length of her intervention that failed to lead to positive results. In addition, she suggested that a possible ceiling effect may have been in place as scores on peer attitude scale we re high initially prior to implementation of co-operative learning. In contrast, Piercy et al. (2002), who only used a ten-week co-operative learning intervention with six children with learning difficulties and 45 typically developing peers, found that typically developing children gave special class children higher peer acceptance ratings, greater popularity indices and lower social distance ratings following the intervention. Putman, Markovchick, Johnson and Johnson (1996) initially questioned the validity of using peer acceptance measures in such short studies, stating that the typical duration of co-operative learning programmes was only three to ten weeks which was an insufficient time to capture typically developing children’s true acceptance levels. Consequently they extended their co-operative learning programme and found that, following an eight-month co-operative learning intervention, significant positive changes occurred in peer ratings for both children with learning difficulties and typically developing children. It would appear, therefore, that the evaluation method of peer ratings of students with learning difficulties has produced positive results but not always consistently so when the intervention is short (lasting for weeks as opposed to months). In addition, measuring peer acceptance over a short period of time can be questioned. Kleck (1966) found that people who do not have disabilities are overly friendly in their initial encounters with people with disabilities, suggesting that a follow-up intervention is really required to assess peer acceptance levels accurately. Evaluation of efficacy using teacher interviews Qualitative structured and semi-structured interviews have been the most popular means of enabling teachers to evaluate co-operative learning programmes in recent years. These interviews are generally used to derive judgements about the programmes’ benefits and efficacy. While their primary evaluation method was observation, O’Connor and Jenkins (1996) also probed teachers on their rationale for using co-operative learning, their goals for students and their perceptions of the effectiveness of co-operative learning using a semi-structured interview. Analyses of their reports revealed that differences in classroom practices contributed to the success levels of co-operative learning interventions. British Journal of Special Education • Volume 32 • Number 3 • 2005 © NASEN 2005 More specifically, teachers reported that selection of partners, teacher monitoring and the establishment of a co-operative ethic was related to successful co-operative learning. Perhaps the most comprehensive and recent teacher evaluation was that conducted by Jenkins, Antil, Wayne and Vadasy (2003), as their study was based on an analysis of how 21 teachers perceived co-operative learning to work with students with special educational needs. These authors used a semi-structured interview to seek information on teachers’ current use of co-operative learning; their judgements about its benefits and efficacy; the participation of students in co-operative learning activities; and any modifications teachers created for students with special educational needs. Teachers were generally positive about co-operative learning’s efficacy for students with learning problems, with all 21 teachers ranking co-operative learning as more effective than other instructional approaches. The three most frequently cited benefits of co-operative learning for students with learning difficulties, each mentioned by more than half of the respondents (52%), were increased self-esteem; the security that comes from being part of a group; and higher success rates and/or better products. While academic benefits were mentioned, they were cited less frequently than social benefits. Thirty-three percent of respondents stated that co-operative learning resulted in better learning for students with special educational needs. Consumer satisfaction surveys offer an alternative to qualitative interviews as a means of evaluation but appear to be less frequently used. Dugan et al. (1995) used such an approach to evaluate the co-operative programme they implemented with students with special educational needs. Their survey consisted of 13 items on a Likert scale which referred to implementation, activities and results. The teacher and paraprofessional involved agreed that co-operative learning groups were easy to implement and manage and that students benefited both academically and socially. Evaluation of efficacy using target child reports Two studies used self-reports from the children with learning difficulties as part of their evaluation procedure of co-operative learning (Nixon, 1999; Putman et al., 1996). Interviews of either a structured or semi-structured format were administered to the children with learning difficulties in both cases. In Putman et al.’s (1996) study, 74% of the students with special educational needs reported that they liked working in the co-operative groups; 13% were unsure about co-operative learning; and 13% did not like working co-operatively. The three target children with ADHD in Nixon’s study reported that working as part of a co-operative learning group had been a positive experience for them. It can be concluded from this review of the efficacy of co-operative learning for students with learning difficulties that the aggregated results from a number of studies are unambiguous both in terms of social and academic benefits. A template outlining details of six of the most recent and © NASEN 2005 comprehensive empirical studies which have been conducted in this area are presented in Table 1. It has emerged that the presence of certain factors will lead to a higher likelihood of successful outcome in co-operative learning programmes. These factors have been outlined in the following section. Factors contributing to the successful implementation of co-operative learning Co-operative learning can be implemented in a structured or an unstructured way (Jenkins & O’Connor, 2003). Structured co-operative learning occurs when students are taught specific strategies as to how to interact. Unstructured co-operative learning occurs when children are guided but not taught specific interaction strategies. The use of social skills training is incorporated within a structured co-operative learning approach. It is proposed that social skills should be taught to all children using the following steps: the skill should be identified by naming it and d e fining it; the importance of the skill should be explained; the skill should be demonstrated; the children should be reminded to used the skill during the day’s activities; feedback should be given to the children on how they are co-operating; and, at the end of the session, children should reflect on their use of the skill and set future goals (Spenciner & Putman, 1998; Johnson, Johnson & Holubec, 1993). Only one study could be located within the review which referred specifically to the use of reinforcement within an intervention. Dugan et al. (1995) provided reinforcement by using a sticker chart for each group. When groups demonstrated the appropriate use of social skills, stars were placed on the group chart under the specific skill column. Nixon (1999) used a token economy system in conjunction with a co-operative learning intervention. The reward system was not therefore part of the co-operative learning intervention but a separate intervention in and of itself. Tokens were awarded to children based on the group’s performance on their worksheet. These tokens could later be exchanged for privileges. According to the six empirical studies outlined in Table 1, co-operative learning sessions appear to be on average 40 minutes in duration and are generally conducted at least twice a week. Academic materials similar to those used in traditional classes are used in conjunction with materials more specific to co-operative learning. Nixon (1999) suggests that daily use of group worksheets and group evaluation sheets are essential to the implementation of co-operative learning. Studies of the benefits of co-operative learning for children with learning difficulties have conclusively suggested that the manner in which co-operative learning is implemented will determine whether it is successful or not: ‘Co-operative learning is a blunt instrument that, depending on its form and implementation, may or may not help students with learning difficulties.’ (Jenkins & O’Connor, 2003, p. 428) British Journal of Special Education • Volume 32 • Number 3 • 2005 161 Table 1: Empirical studies on co-oper ative learning Study Participant(s) Design Evaluation Procedure(s) Outcome Kamps et al.

Peer acceptance measures 2. 10-minute observation of each child during one-hour free choice activity before and after intervention Literature re fe rring specifically to the effectiveness of co-operative learning for children with learning difficulties has identified a number of subcomponents that appear to be essential to successful implementation. O’Connor and Jenkins (1996), in their study of co-operative learning, found certain classroom practices were related to successful co-operative learning experiences for students with disabilities. Practices common to more effective groups involved the formation of partnerships, teaching co-operative behaviours and monitoring group functioning during co-operative activities. In particular, two practices seemed to disrupt group functioning and dissolve interdependence: adult assistance and modifying assignments. In several cases, O’Connor and Jenkins observed adults, most noticeably teaching assistants, joining the co-operative learning groups. When this occurred, it invariably altered the character of the group’s participation. Sometimes the adult directed the student’s work and sometimes the adult assumed the role of group leader. They found that students with disabilities usually worked with more sustained effort and made more effective contributions to groups when their assignments matched those of their peers. In a later study, Jenkins et al. (2003) reported that all but two of 21 teachers interviewed described 162 making some adjustments. A list of recommendations for teachers aimed at facilitating the performance of students with special educational needs is set out in Table 2. Selecting suitable work partners was the most common adjustment mentioned. According to a ‘safe and responsive schools’ publication, co-operative group composition and group interaction processes have been found to impact upon the success or failure of co-operative learning groups. Teachers should provide the g roups with initial training on co-operative learning procedures as well as group social skills. Teachers should continue to provide ongoing monitoring and re i n fo rcement to the students for implementing the procedures, although Dugan et al. (1995) and Nixon (1999) are the only two authors from the six studies listed in Table 1 who specify the importance of monitoring and reinforcement. The elements of co-operative learning which are and are not implemented also influence outcome. It was revealed by Antil et al. (1998), in their review of how 21 teachers conceptualised and implemented co-operative learning, that many teachers failed to implement even the most basic of elements such as creating individual accountability and evaluating group processes. According to these authors, there are discrepancies between co-operative learning British Journal of Special Education • Volume 32 • Number 3 • 2005 © NASEN 2005 practices described by teachers and the approaches advocated by co-operative learning researchers. It is impossible to conclude whether an intervention is successful or not when it has not been implemented correctly in the first place. None of the recent six empirical studies outlined in Table 1 incorporated teacher training as to how to implement co-operative learning. According to Walters (2002), models of co-operative learning that promote its two key components – independent work and individual accountability – are consistently found to lead to gains in achievement. According to Slavin (1995), 37 of 44 studies comparing traditional instruction with co-operative learning methods which included these two elements found significantly positive effects. Only four of 23 studies of co-operative learning methods lacking group goals and individual accountability found positive effects for student achievement. According to Dugan et al. (1995), in their study of children with autism, several characteristics of co-operative learning groups as an intervention package may be important to their success including: • • • • • structured tasks, worksheet activities and research projects; a relatively small class size with adults providing continuous monitoring of small groups; heterogeneous groups; frequent individual quizzes to check students’ learning; reinforcement of social skills for each group throughout the programme.

Ensure the intervention is sufficiently long – failure to develop maturity will lead to reduced effectiveness. Intervention needs to be sufficiently long. The group must be allowed to mature. Teachers should be trained as to how to implement all the essential elements of co-operative learning. © NASEN 2005 According to Johnson and Johnson (1994), there are conditions under which co-operative learning groups function effectively and conditions under which groups function ineffectively. One of the obstacles to effective functioning which they outline suggests that temporary, ad hoc groups usually do not develop enough maturity to function with full effectiveness. It also appears that if a group is to achieve a deep level of understanding then a number of potential answers should be considered and a decision should then be made rather than relying on one dominant response. Furthermore ‘social loafing’ can occur when one member works less hard than the rest. Finally ‘free-riding’ occurs when a group member feels group success depends very little on them and so they make little effort. Conclusion Results on the efficacy of co-operative learning vary greatly depending on the variables assessed and the type of evaluation procedure used. Reviews of formal academic assessments have reported the least positive results. In contrast, observation studies in which social and academic behaviours have been defined and then measured quantitatively have produced the most positive results. This review would suggest that, to ensure a comprehensive evaluation of a co-operative learning programme, a multi-component evaluation procedure should be used. Pre-test and post-test observation of social and academic behaviours; pre-test and post-test administration of peer acceptance measures; post-test teacher interviews or consumer satisfaction surveys; and post-test interviews with target students should all form part of a compre h e n s ive eva l u ation of any co-operat ive learning programme. The manner in which co-operative learning programmes have been implemented vary enormously. This variation has lead to difficulties in d rawing definite conclusions about the effi c a cy of co-operative learning for students with learning difficulties. Teacher training is therefore an important prerequisite to the implementation of a co-operative learning programme. With such a large difference between the models implemented by teachers and those proposed by researchers, an important recommendation is that teachers should rehearse strategies fi rst based on the advice outlined in Table 2. Th o s e co-operative learning interventions that have been researched have generally been short, on average three to ten weeks in duration. Co-operative learning is often implemented as part of a multi-component intervention. It is very difficult to decipher the exact effects of co-operative learning, when other interventions have been implemented simultaneously. Future studies should therefore ensure that co-operative learning is implemented properly: ensuring that essential elements, such as creating interdependence and individual accountability, are in place; that the intervention is implemented for as long a time period as possible; and that the intervention is implemented as a sole intervention where possible. Empirical researchers to date fail sufficiently to describe the exact types of co-operative learning intervention strategies they implemented or how they went about implementing them. This is essential if the effectiveness of the various models and their critical components is to be usefully compared.
