Overcoming the potential dilemma of awarding the same grade to a group of students for group work assignments, regardless of the contribution made by each group member, is a problem facing teachers who ask their students to work collaboratively together on assessed group tasks. In this paper, we report on the procedures to factor in the contributions of individual group members engaged in an integrated group project using peer assessment procedures. Our findings demonstrate that the method we used resulted in a substantially wider spread of marks being given to individual students. Almost every student was awarded a numerical score which was higher or lower than a simple group project mark would have been. When these numerical scores were converted into the final letter grades, approximately one-third of the students received a grade for the group project that was different from the grade that they would have received if the same grade had been awarded to all group members. Based on these preliminary findings we conclude that peer assessment can be usefully and meaningfully employed to factor individual contributions into the grades awarded to students engaged in collaborative group work.  相似文献

This experimental study is aimed at examining the effect of involving pupils in primary education in setting assessment criteria and standards on their appraisal of a peer’s work and their peer feedback style. It is expected that our intervention will lead to (1) a criteria-referenced appraisal and (2) more final vocabulary, which is associated with a more authoritative style. In total, 95 sixth grade pupils from The Netherlands were randomly assigned to one of two conditions. In the experimental group, the pupils first received an exemplar, which was followed by a group discussion about appropriate assessment criteria and standards. In the control group, the pupils provided peer feedback without this discussion. Their peer appraisal was measured with a questionnaire and feedback style was determined by analysing the written feedback using a person-oriented approach (cluster analysis). Results showed that the chance that pupils in the experimental group had an authoritative style was three times higher than in the control group. Theoretical and practical implications of the study are discussed.  相似文献

Group work can form a substantial component of degree programme assessments. To satisfy institutional and student expectations, students must often be assigned individual marks for their contributions to the group project, typically by mapping a single holistic group mark to individual marks using peer assessment scores. Since the early 1990s, various mapping methods that use self- and peer ratings have been developed. They are based on (normalised) individual weighting factors, partial scaling of the group mark, inter-rater agreement corrections or parabolic functions. We show that no single existing method can be successfully applied to most practical peer assessment scenarios such as different marking scale interpretations, intra-group ranking errors, biased free-riders and marks exceeding 100%. We present a combined analytical mapping method that incorporates the benefits of existing mechanisms, but alleviates their weaknesses with minimum computational effort and tutor input. The robustness of the method is illustrated through problematic assessment examples and empirically evaluated in multiple group work environments involving a total of 243 students and five different disciplines.  相似文献

There are many reasons to assign group projects but determining the grade for each individual working in a group can be problematic. Self and peer assessments of contributions to a group project can be used to adjust individual grades. Most studies of such assessments have considered teams with three to seven members. This study documents the degree of congruence between self and peer assessments of contributions to a project assigned to teams of two people. The majority of students (88.6%) assigned equal credit to themselves and to their partner. Only 16.2% of students had their grades adjusted by the assessment process and most of those adjustments were small. These findings may alleviate concerns of instructors and students about the fairness of assigning individual grades to students working on a project in teams of two.  相似文献

Peer assessment has been increasingly integrated in educational settings as a strategy to foster student learning. Yet little has been studied about how students at different learning levels may benefit from peer assessment. This study examined how peer-assessment and students’ learning levels influenced students’ project performance using a two-way factorial design. One hundred and thirty teacher education students participated in this quasi-experimental study. When working on a technology-integrated lesson plan project, the experimental group completed an online peer assessment process while the control group followed the discussion method. Students’ learning levels were measured and divided into low, average and high achieving according to the quality of their draft lesson plans. Data analysis suggested that the impact of peer assessment on students’ lesson plan project seemed to vary according to students’ learning levels. While low- and average-achieving students showed significantly improved performance right after the integration of a peer assessment model, the model seemed to have had less impact on the performance of high-achieving students. Significance, implications and limitations of findings are discussed.  相似文献

Honours research projects in the School of Civil, Environmental and Mining Engineering at the University of Adelaide are run with small groups of students working with an academic supervisor in a chosen area for one year. The research project is mainly self-directed study, which makes it very difficult to fairly assess the contribution of individual students to a group-based research project. Until recently, a paper-based method of self and peer assessment (SPA) for the honours research projects was used to assess the projects. This was unsatisfactory for both students and academic staff, who found that the same mark was often awarded by the peers to each student without feedback. In 2010, therefore, an online SPA tool, SPARK, together with a set of newly developed assessment criteria, were used for SPA by the honours students. The new SPA criteria are based on teamwork and research skills, and the new rating scales reflect standard academic grades. Surveys of the students confirmed that they found the criteria and scales much more suitable for the assessment of group work and design projects.  相似文献

Abstract

Group work, where students work on projects to overcome challenges together, has numerous advantages, including learning of important transferable skills, better learning experience and increased motivation. However, in many academic systems the advantages of group projects clash with the need to assign individualised marks to students. A number of different schemes have been proposed to individualise group project marks, these include marking of individual reflexive accounts of the group work and peer assessment. Here, we explore a number of these schemes in computational experiments with an artificial student population. Our analysis highlights the advantages and disadvantages of each scheme and particularly reveals the power of a new scheme proposed here that we call pseudoinverse marking.

This report describes a small study that analysed module marks of one cohort of science undergraduates from one academic year. It explored how group summative assessment marking affected the overall marks in comparison with individual assessment. A tutor allocated students to mixed ability project groups. Individual marks for the group work component were derived by tutor‐, peer‐, and self‐assessment weighting. The results showed that students with high individual marks obtained lower marks in the group component. Similarly, students with low individual marks obtained higher marks in the group component. Study limitations, results and conclusions are reported.  相似文献

This study proposes an advanced method to factor in the contributions of individual group members engaged in an integrated group project using peer assessment procedures. Conway et al. proposed the Individual Weight Factor (IWF) method for peer assessment which has been extensively developed over the years. However, most methods associated with IWF use a simple average algorithm which still has limitations in effectively reflecting abnormal situations. Therefore, this study proposes an iterative method for measuring a fair IWF by considering each assessor's reliability. The proposed algorithm considers each assessor's reliability which is evaluated by an analysis of variance of the scores given by the assessor. This relative reliability factor is used to improve the fairness of the IWF and reduce the effect of unfair or unreliable assessors' scores. A comparison with previous methods demonstrates that the proposed method resulted in substantially more fair grades being given to individual students for group projects.  相似文献

This paper reports on the second phase of a project designed to improve students’ understanding of assessment demands. In Stage 1, Level 1 students were involved in a range of activities culminating in peer marking. This peer assessment was, itself, marked by the tutors to encourage students to engage positively with the process. Stage 2 of the project investigated whether these various intervention activities had any long-term impact on sports studies students’ approach to writing assignments. Interviews were conducted with six students who participated in Stage 1. For comparison purposes, a matched group of students from another vocationally-related course were also interviewed. The findings suggest that the peer assessment did encourage students to pay attention to assessment information. However, the students placed greater stress on the role of informal support, particularly verbal clarification of written guidance and feedback. The article concludes with a discussion of the implications for practice.  相似文献

The study reports on a one-semester-long intervention study of peer assessment in a college English writing class. The purpose of the study was to investigate the effects of peer assessment on learner autonomy (LA). Seventy English major sophomores from an independent college in China participated in the study, who were randomly divided into two groups of 35 students each. Traditional teacher feedback was used in the control group while peer assessment was adopted for the experimental group. A questionnaire on LA was administered to both groups as the pre-test and the post-test. A number of ANCOVA analyses were run to measure the effects of peer assessment on students’ LA. The results indicate that peer assessment enhanced the students’ learner autonomy. Peer assessment significantly reduced learners’ dependence on the teacher and boosted the students’ confidence in learning ability, while failing to make noticeable improvement in the other aspects of LA.  相似文献

This article complements two previous papers which presented quantitative data about methods of peer assessment within a group project. The previous quantitative papers indicated that holistic peer assessment supports the purposes of summative group assessment better than category-based peer assessment. The qualitative findings presented here support this notion. Student attitudes towards the two methods of peer assessment were more supportive of the holistic approach than the category-based approach. This article raises the question as to whether the method of peer assessment has some influence on the extent to which students work cooperatively in a group setting.  相似文献

Abstract

In recent years, there has been an increasing use of peer assessment in classrooms and other learning settings. Despite the prevailing view that peer assessment has a positive effect on learning across empirical studies, the results reported are mixed. In this meta-analysis, we synthesised findings based on 134 effect sizes from 58 studies. Compared to students who do not participate in peer assessment, those who participate in peer assessment show a .291 standard deviation unit increase in their performance. Further, we performed a meta-regression analysis to examine the factors that are likely to influence the peer assessment effect. The most critical factor is rater training. When students receive rater training, the effect size of peer assessment is substantially larger than when students do not receive such training. Computer-mediated peer assessment is also associated with greater learning gains than the paper-based peer assessment. A few other variables (such as rating format, rating criteria and frequency of peer assessment) also show noticeable, although not statistically significant, effects. The results of the meta-analysis can be considered by researchers and teachers as a basis for determining how to make effective use of peer assessment as a learning tool.  相似文献

The work that this paper reports concerns a small scale investigation and evaluation of the technique of peer group review in the assessment of design and technology project work. A cohort of fifty first year undergraduate students of Industrial Design and Technology was involved in the assessment of four practical design coursework projects which they had submitted.

Two particular aspects of peer group review are considered: the validity of student assessment in relation to parallel judgements made by academic staff; the perceptions which undergraduate students hold regarding the benefits and difficulties of this system of assessment. The paper seeks to identify the potential contribution that the technique of peer group review could make towards more effective and efficient assessment of design and technology project work from student and staff perspectives.  相似文献

In this study the relationship between domain-specific skills and peer assessment skills as a function of task complexity is investigated. We hypothesised that peer assessment skills were superposed on domain-specific skills and will therefore suffer more when higher cognitive load is induced by increased task complexity. In a mixed factorial design with the between-subjects factor task complexity (simple, n?=?51; complex, n?=?59) and within-subjects factor task type (domain-specific, peer assessment), secondary school students studied four integrated study tasks, requiring them to learn a domain-specific skill (i.e. identifying the six steps of scientific research) and to learn how to assess a fictitious peer performing the same skill. Additionally, the students performed two domain-specific test tasks and two peer assessment test tasks. The interaction effect found on test performance supports our hypothesis. Implications for the teaching and learning of peer assessment skills are discussed.  相似文献

This paper reports a study which implemented and evaluated a method of peer assessment, as a formative and summative assessment procedure. Pairs of first‐year undergraduate biology students were asked to complete a poster assignment on a specific aspect of nerve physiology. This paper contains details of a method which allows student peer and tutor marking of work against the individual marking criteria to be evaluated. The results show that a comparison between the tutor and the student peer mark may be misleading as a guide to the validity of peer assessment. The importance of considering the individual sections of the marking criteria is illustrated. It was found that when the individual criteria were analysed the number of students marking the same as the tutor ranged from 31% to 62%. It also became clear that specific areas of the marking criteria were prone to over and under‐marking. Analysis of student feedback forms showed that students not only liked carrying out peer assessment, but felt the benefits in terms of developing facets of their learning process and heightening their awareness of their work. These results are discussed in the light of other studies.  相似文献

Peer assessment has been used successfully in higher education, with important benefits reported in terms of student learning. However, most of the literature has focused on its use with small groups of students taught by staff who are committed to the peer assessment process. This paper reports the development of peer assessment procedures for use in large classes, using a cyclical process of action, reflection and refined action. The project was carried out in three phases and after each phase changes were made to the procedures in response to student and staff feedback. The development of procedures is discussed in relation to assessment tasks, assessment criteria, anonymity, procedural guidelines, distribution systems, marking procedures and tutor remarking. Although there are specific difficulties associated with the use of peer assessment in large classes, this study suggests that these are outweighed by the learning benefits for students. Based on the findings of this study, recommendations are made for ways in which peer assessment might be successfully applied in large classes.  相似文献

The main interest in this article is students’ involvement in assessment as a part of growth towards self‐directedness in learning. In order to enhance students’ development of autonomy in learning, a project involving ‘older’ students as peer examiners for ‘younger’ students was designed and carried out. Students in the sixth semester in a PBL‐based Master’s program of Medical Biology participated, together with faculty, as examiners of fifth‐semester students. The examination and the assessment situation was carefully designed based on learning theories, empirical evidence and experiences underpinning student‐centred learning, especially in the form of PBL used at the faculty. The project was evaluated and analysed in order to understand students’ learning processes related to the responsibility for assessing peers. The situation of the peer examiners was interpreted based on their own experiences with statements from the students assessed and faculty involved in the assessment. Evaluations from six occasions, spring and fall, 2003–2005, were included in the study. The findings suggest that involving students in assessment as equal partners with faculty makes it is possible for students to apprehend the metacognitive competences needed to be responsible and autonomous in learning. The peer examiners experience motivation to learn about learning, they acquire tacit knowledge about assessment and they learn through being involved and trusted. The student‐centred educational context, which requires responsibility throughout the programme, is recognized as very important.  相似文献

The aim of this study is to examine the effectiveness of collaborative learning with hints and peer tutoring with hints, and individual learning with hints in chemistry laboratory education in a secondary school. A total of 96 eleventh graders participated in this study. The study has a randomized pre‐test and post‐test design with a delayed post‐test. During the four‐week intervention, students were required to carry out eight lab tasks in total. The students filled in a 17‐item self‐assessment of learning gain questionnaire on the last day. Analyses of students’ learning achievements showed that students in both the collaborative learning and peer tutoring situations outperformed those learning individually with hints. The delayed post‐test, which was administered three months later, revealed that students who had been in the peer tutoring situation outscored those in the collaborative learning situation. Student self‐assessment questionnaires on learning gain provided further details in this regard.  相似文献

In this case study our aim was to gain more insight in the possibilities of qualitative formative peer assessment in a computer supported collaborative learning (CSCL) environment. An approach was chosen in which peer assessment was operationalized in assessment assignments and assessment tools that were embedded in the course material. The course concerned a higher education case‐based virtual seminar, in which students were asked to conduct research and write a report in small multidisciplinary teams. The assessment assignments contained the discussion of assessment criteria, the assessment of a group report of a fellow group and writing an assessment report. A list of feedback rules was one of the assessment tools. A qualitative oriented study was conducted, focusing on the attitude of students towards peer assessment and practical use of peer assessment assignments and tools. Results showed that students’ attitude towards peer assessment was positive and that assessment assignments had added value. However, not all students fulfilled all assessment assignments. Recommendations for implementation of peer assessment in CSCL environments as well as suggestions for future research are discussed.  相似文献
