Peer review feedback, developed to assist students with increasing the quality of group reports and developing peer review skills, was added to a master’s level Climate Change Policy and Planning unit. A pre- and post-survey was conducted to determine whether students found the process a valuable learning opportunity: 87% of students responding to the post-review survey indicated they saw benefit in both developing and receiving peer review feedback. Peer review design minimising the potential for plagiarism resulted in low levels of student concern surrounding plagiarism. Marks allocated by students were valid (consistent with the lecturer) and were generally reliable; however, distribution of marks had a higher variance where group report quality was low. Training on completing the peer review template could result in more reliable feedback. Consistent with the literature, the feedback developed during the peer review process focused on style and presentation preferentially to content. Seven out of eight group reports improved between report submissions, with all groups responding to peer review feedback. Peer review feedback and changes made to group reports indicated students had limited capacity to judge the quality of referencing and critical analysis. 相似文献

Comparative Judgement (CJ) is an increasingly widely investigated method in assessment for creating a scale, for example of the quality of essays. One area that has attracted attention in CJ studies is the optimisation of the selection of pairs of objects for judgement. One approach is known as adaptive comparative judgement (ACJ). It has been claimed in the literature that ACJ produces very high reliability, often higher than can be obtained by conventional marking. Bramley showed by simulation that adaptivity can substantially inflate the apparent reliability in ACJ. The empirical study described here compared an adaptive with a non-adaptive CJ study using GCSE English essays. An all-play-all set of comparisons of a subset of the essays allowed the extent of scale inflation to be quantified: the reported adaptive reliability was 0.97 whereas the deflated value was 0.84. The value from the non-adaptive study was 0.72. However, the scale from the non-adaptive study correlated slightly higher with external variables, suggesting the non-adaptive study was no less valid than the adaptive one. 相似文献

Lincoln Memorial University‐DeBusk College of Osteopathic Medicine (LMU‐DCOM) offers an optional three‐week summer Anatomy Boot Camp course (ABC) to facilitate students' transition into medical school and promote retention of anatomy subject matter. The pre‐matriculation program is a supplemental instruction course that utilizes a small group learning format. Boot camp instruction is led by teaching assistants and two anatomy professors. Enrollees gain early exposure to Medical Gross Anatomy (MGA) course subject matter, which is taught in the fall semester, and learn study skills necessary to excel in medical school. No grade is assigned for the course, therefore participants can study without the fear of potentially affecting grades. This study evaluates the effectiveness of the LMU‐DCOM ABC course using data from four consecutive summers. Independent two‐sample t‐tests were used to compare ABC to non‐ABC students for the following variables: incoming grade point average (GPA) and Medical College Admission Test® (MCAT®) scores, MGA written and laboratory practical examination grades, and final MGA course grade. Additionally, a 26‐question survey was administered to 2012–2014 boot camp participants. There were no significant differences in incoming GPA and MCAT scores. However, boot campers scored significantly higher on the first two lecture and laboratory examinations (P < 0.05) for each year of the study. Thereafter scores varied less, suggesting a faster head start for boot camp participants. Mean MGA final grade was on average 3% higher for the boot camp cohort. The survey feedback supports that the ABC course assists with the academic and social transition into medical school. Anat Sci Educ 10: 215–223. © 2016 American Association of Anatomists. 相似文献

在高校外语教学中,四、六级外语统考已经成为大学生必须参加的一种考试。因为有了四级证,学生就业机会就会增大。但外语测试中存在着相当多的问题,如试题题型单一,猜测性较大,导致应试教学的产生,不能调动学生学习的自主性和积极性,也不能有效地考查出学生的实际水平,因此,我国的大学外语测试亟待改革。 相似文献
