Peer assessment can be important in developing active and independent learners, as well as providing more and faster feedback in large classes, compared to marking done by tutors. In addition, the evaluative, critical stance required by students in order to assess their peers' work encourages the development of higher-order cognitive skills. Changing roles from being assessed to being an assessor can also improve students' ability to judge and improve on their own work. However, peer assessment does have potential problems and there is some debate as to the appropriate academic level at which to implement it, the kinds of feedback that are given and the ways in which students respond. In addition, there is little evidence that peer assessment has an impact on academic performance. This research reports the results of an online peer assessment exercise for a macroeconomics essay conducted in a large Economics 1 class at Rhodes University. Of the 800 students, about half participated in the peer assessment exercise. Data were collected from students via a formal course evaluation. In addition, a sample of 50 essays was evaluated in terms of the relationship between peer marks and final (tutor) marks received and the impact that peer assessment had on the quality of the final essay submitted. An Ordinary Least Squares regression was used to investigate the impact of peer assessment participation on marks. Results showed that peer marks tended to ‘bunch’ in the 60–68% range, indicating the reluctance of peers to give very high or low marks. In general, peers gave more useful feedback on technical aspects, such as presentation and referencing (which were also the categories in which students most often made improvements), than on content. Regression analysis showed that peer assessment participation was not a significant determinant of final essay mark, but that economics ability and English language proficiency were.  相似文献

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

Assessing contributions to group assignments   总被引：2，自引：1，他引：2  
We report the use of a combination of self‐ and peer‐assessment in an undergraduate social psychology laboratory course. Students worked in small groups on a self‐directed empirical project that they each wrote up independently as a laboratory report. Marks for the written assignment were moderated by a contribution index measure based on the self‐ and peer‐assessment measures. Our analyses indicated that: (i) students took the peer‐assessment process seriously, clearly differentiating between group members on the contributions questionnaires; (ii) students show a self‐bias, rating their own contribution to the group task higher than that of other group members; (iii) for a large majority of students the contribution index resulted in very little moderation of the final assignment marks; (iv) there was a strong correlation between the contribution index and the overall assignment score. Implications for the assessment of group work are considered.  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

Assessment for learning approaches, such as peer review exercises may improve student performance in summative assessments and increase their satisfaction with assessment practices. We conducted a mixed methods study to evaluate the effectiveness of an oral peer review exercise among post-graduate students. We examined: (1) final assessment grades among students who did and did not take part in the peer review exercise; (2) student perceptions of the impact of the peer review exercise; and (3) student understanding of, and satisfaction with, this new assessment practice. We found that students who took part in the exercise had a significantly higher mean grade in a subsequent summative oral presentation assessment than students who did not take part in the exercise. Students gained a better understanding of assessment and marking criteria and expressed increased confidence and decreased anxiety about completing the subsequent summative assessment. Assessment for learning improves academic attainment and the learning experience in postgraduate students.  相似文献

Active participation in learning activities and reviewing assessment activity can facilitate learners engaged in these processes. This case study reports student experiences of the process of peer assessment with teacher guidance in a group project for a first-year nursing course with 153 students. Twenty groups of students were assigned roles in exploring one of the two scenarios: one involved analysing diabetes mellitus and the other considered colorectal carcinoma, in each case covering provision of acute nursing care in hospitals and preparing health promotion strategies in a community. Each group also provided comments to the group that worked on the other scenario, based on prearranged assessment criteria. After receiving comments from their peer group, each group was then allowed to revise their drafts prior to final submission. The teacher’s input would be offered, if the peer feedback was inaccurate or insufficient. A survey was conducted to explore the learning experiences, and three semi-structured focus group interviews were conducted to triangulate findings with the survey. The first-year students expressed the need for both peer feedback and the lecturer’s direct guidance.  相似文献

To encourage increased student attendance and engagement in a third-year economics unit, the curriculum was redesigned to incorporate continuous assessment throughout the semester. A component of group project marks were allocated to peer assessment, in an attempt to address concerns about free-riding colleagues sharing a common mark. This study investigated the consistency of marks awarded to peers within teams, and the acceptance by students of marks awarded by peers. Students were asked to provide ratings and explanatory comments for each of their group peers. Focus groups were conducted to determine students’ acceptance of this strategy. Eighty student ratings were compared to determine consistency of assessment. Within groups, students who received higher marks from their peers generally awarded marks to their peers across a wider range, whereas students who received lower average grades often awarded the same mark to all team members. These results might indicate that students who were attending class regularly and/or contributing at a higher level were more discriminating in the marks awarded to their peers. Similarly, non-contributors (as identified by their peers) assigned the same or similar grades to each of their peers, possibly due to a lack of knowledge about their peers’ contributions.  相似文献

Peer assessment provides a useful mechanism to develop many positive qualities in students studying in higher education (HE). Potential influences on peer‐awarded marks include student qualities such as gender, HE background (e.g. university affiliation) and participation in the development of the assessment criteria. Many studies that have investigated peer assessment have placed great emphasis on marks from a single tutor, or very few tutors, from a single university. This study examined grades awarded by 11 tutors (affiliated with four universities) to oral presentations delivered on a residential field course by second‐year undergraduate students from two universities studying environmental or biological disciplines. Student assessors awarded marks of fairly high precision (correlating strongly with tutor grades) but averaged 5% higher than their tutors (i.e. of only moderate accuracy). Marginally higher marks (circa 1.6%) were awarded by student assessors to speakers studying at the same university. Gender influences were detected as males tended to grade other male speakers very slightly more highly than female speakers. Marks from females were unaffected by speaker gender. Students who participated in the development of the assessment criteria did not achieve higher grades for their presentations. However, when these ‘participants’ were assessing, they awarded lower marks than their peers (i.e. closer to, but not as low as, those awarded by tutors). Lower marks were also awarded during the middle of sessions, possibly resulting from factors associated with motivation and attention of speakers and markers. Overall, the potential biases in marking by naive assessors examined in this study may influence the validity of marks generated by peer assessment schemes, but the experience of this type of assessment had positive effects on those involved.  相似文献

Peer assessment of long written tasks poses particular problems as these tasks typically involve complex learning and solving ill‐structured problems which require divergent responses. Marking reliability of this kind of writing task is difficult to achieve. The author illustrates this through an evaluation of two implementations of peer assessment, involving 81 students, in a UK university. In these implementations, all peer assessor grades were returned to students (not just mean grades). In this way students were exposed to subjectivity in marking. The implementations were evaluated through questionnaires, focus groups, observations of lectures and tutor interview. While students reported a better understanding of quality in student writing as a result of their experience, many complained that peer assessors’ marks were not ‘fair’. The article draws on recent research on the reliability of tutor marking to argue that marking judgements are subjective and that peer assessment offers the opportunity to explore subjectivity in marking, creating an opportunity for dialogue between tutors and students.  相似文献

Abstract

Positive student attitude towards peer assessment can be demonstrated through high-quality peer assessment activities. Research findings on students’ attitudes before and after such activities were mixed. This study was conducted using a mixed-methods approach to investigate the underlying factors influencing students’ attitude change. Participants were students enrolled in an online graduate-level assessment course in the college of education in a university in the southeast United States in the fall of 2017 (N?=?31). Surveys and interviews were used to collect quantitative and qualitative data separately, both of which indicated that perceived accurate and specific feedback tended to help students shift to more positive attitudes towards online peer assessment. In addition, final task score improvement after the activity was correlated with positive attitude change. Qualitative results also identified other factors, such as communication with the peers’ work and logistic concerns. The current study offers insights for researchers and instructors to promote positive attitude changes in online peer assessment activities.  相似文献

The purpose of this paper is to provide a proof of concept of a collaborative peer-, self- and lecturer assessment processes. The research presented here is part of an ongoing study on self- and peer assessments in higher education. The authentic assessment for sustainable learning (AASL) model is evaluated in terms of the correlations between sets of marks. The article provides an explanation of the assessment process, and analyses sets of marks as a means of justifying the validity of the process. The results suggest that students, even those with no prior experience in peer- or self-evaluation, in their first year of tertiary study, under the right conditions, are able to accurately judge their own work and make reasonably accurate judgements of the work of their peers. While previous studies have expounded the benefits of self- and peer assessments in tertiary study, undertaking a prescribed process, such as AASL, has a further implication in allowing others to replicate the process with reasonable assuredness of the validity of the process across various fields of study.  相似文献

Peer assessment can be conducted online with rapid development of online learning technology. The current study was conducted empirically to investigate peer rating accuracy and student learning outcomes in online peer assessments, comparing compulsory and voluntary peer assessment. Section 1 (N?=?93) was assigned to the voluntary group and Section 2 (N?=?31) was assigned to the compulsory group. The results showed the voluntary group scored significantly higher than the compulsory group in the final task of the course, while there was no significant difference on the final task score increase. Students who participated in the voluntary group provided more accurate scores (i.e. peer rater accuracy) than those who participated in the compulsory group. The peer score leniency/severity rating, comparing peer assigned scores with the teacher assigned scores, were generally consistent with the peer rater accuracy results. The current study offers insights for researchers who are interested in studying the effect of online peer assessment activities. The results are also of interest for instructors who may want to conduct peer assessments in online courses and are choosing between compulsory and voluntary formats.  相似文献

This study examines the impact of an assessment training module on student assessment skills and task performance in a technology-facilitated peer assessment. Seventy-eight undergraduate students participated in the study. The participants completed an assessment training exercise, prior to engaging in peer-assessment activities. During the training, students reviewed learning concepts, discussed marking criteria, graded example projects and compared their evaluations with the instructor’s evaluation. Data were collected in the form of initial and final versions of students’ projects, students’ scoring of example projects before and after the assessment training, and written feedback that students provided on peer projects. Results of data analysis indicate that the assessment training led to a significant decrease in the discrepancy between student ratings and instructor rating of example projects. In addition, the degree of student vs. instructor discrepancy was highly predictive of the quality of feedback that students provided to their peers and the effectiveness of revisions that they made to their own projects upon receiving peer feedback. Smaller discrepancies in ratings were associated with provision of higher quality peer feedback during peer assessment, as well as better revision of initial projects after peer assessment.  相似文献

This article analyses the use of peer and self-assessment in oral presentations as complementary tools to assessment by the professor. The analysis is based on a study conducted at the University of Girona (Spain) in seven different degree subjects and fields of knowledge. We designed and implemented two instruments to measure students’ peer and self-assessment, and a rubric to guide the assessment process. Results were compared with the marks awarded by the professor. In contrast with studies by other authors, which show a high correlation between these different assessment systems, our study revealed significant deviations. Applying peer and self-assessment to oral presentation activities also demonstrates their formative value above and beyond their summative usefulness.  相似文献

This paper reports a case study that investigated the practice of peer assessment in a professional course, with particular emphasis on students’ experience. It was found that peer assessment processes were beneficial to students’ learning and development as professionals. The case study pointed to several conditions for effective implementation of peer assessment, which also relate to assessment in general. These conditions include: (a) adequate and appropriate preparation for the use of peer assessment; (b) alignment of assessment, learning objectives and the broader purpose of the course (e.g. preparation as professionals); (c) the availability of assistance from a teacher throughout the peer assessment process; and (d) constructive discussions following peer assessment, sensitively handled by a teacher.  相似文献

In the last decade, with the increased attention to learner-centred curricula, the topic of self-assessment and peer assessment has become of particular interest in testing and evaluation. The present study explores the role of self-assessment, and peer assessment in promoting writing performance of language learners. To do this, 157 intermediate TEFL (Teaching English as Foreign Language) students were assigned to five different treatments in five groups: four experimental groups and one control group. The first experimental group did journal writing as a self-assessment technique, the second group self-assessed their own writings, the third group employed peer assessment, and the fourth group had both self- and peer assessment. Moreover, there was teacher assessment in all experimental groups, except the fourth group, i.e., the self- and peer assessment group. In the control group, there was only teacher assessment. Also, at the beginning and end of the semester, all participants took a writing test. The design of the study was quasi-experimental, non-randomised control group, pre-test–post-test design. The results revealed that in the second and third groups, in which the students employed self-assessment and peer assessment, together with teacher assessment, we observed the maximum improvement in writing.  相似文献

Fieldwork training is a key component of several practical disciplines. In this study, students’ peer assessment of fieldwork is explored as a method to improve their practical training. Peer assessment theories are first discussed. A framework for peer assessment of fieldwork is proposed, and the steps taken for preparation of students for this task are discussed. A developed marking, feedback and moderation tool of assessment are presented. Application of peer assessment in the field was investigated over a period of two years in one undergraduate unit in the geospatial discipline as an example. Reliability of peer assessment was estimated by measuring the difference between assessments carried out by groups of peer assessors, and its validity was measured by comparing students’ marks with those given by tutors. Results show that students have gained from the peer assessment process, mainly as a formative form of assessment, by better understanding and endeavouring to achieve the objectives of field tasks. Tutors use differences among assessments made by groups of students compared to tutors’ assessments to identify field components that need better explanation of their content and assessment criteria.  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.

Although studies have examined the validity of peer assessment, research including students’ own experiences of peer assessment is scarce. The present study aims to improve assessment practices in a context with a highly traditional assessment culture. The aim is first to examine the validity of peer assessment by analysing the compatibility of student and teacher evaluation and explore the differences between minor and major students’ evaluations. Second, the study examines students’ experiences of peer assessment. Peer assessment was implemented in a large bioscience course with 79 student participants. After the peer assessment, the students provided feedback. The results indicate that student subject understanding can be supported through a proper assessment practice. Peer assessment was successful in an introductory class with minor and major students, and most students experienced it as supportive of their learning.  相似文献

This study implemented an online peer assessment learning module to help 36 college students with the major of pre-school education to develop science activities for future instruction. Each student was asked to submit a science activity project for pre-school children, and then experienced three rounds of peer assessment. The effects of the online peer assessment module on student learning were examined, and the role of Scientific Epistemological Views (SEVs) in the learning process was carefully investigated. This study found that student peers displayed valid scoring that was consistent with an expert’s marks. Through the online peer assessment, the students could enhance the design of science activities for future instruction; for instance, the science activities became more creative, science-embedded, feasible and more suitable for the developmental stage of pre-school children. More importantly, students with more sophisticated (constructivist-oriented) SEVs tended to progress significantly more for designing science activities with more fun, higher creativity and greater relevancy to scientific knowledge, implying that learners with constructivist-oriented SEVs might benefit more from the online peer assessment learning process. These students also tended to offer more feedback to their peers, and much of the peer feedback provided by these students was categorized as guiding or helping peers to carefully appraise and plan their science activity projects. This study finally suggested that an appropriate understanding regarding the constructivist epistemology may be a prerequisite for utilizing peer assessment learning activities in science education.  相似文献
