We investigate students’ negative perceptions about an online peer assessment system for undergraduate writing across the
disciplines. Specifically, we consider the nature of students’ resistance to peer assessment; what factors influence that
resistance; and how students’ perceptions impact their revision work. We do this work by first examining findings from an
end-of-course survey administered to 250 students in ten courses across six universities using an online peer assessment system
called SWoRD for their writing assignments. Those findings indicate that students have the most positive perceptions of SWoRD
in those courses where an instructor graded their work in addition to peers (as opposed to peer-only grading). We then move
to an in-depth examination of perceptions and revision work among 84 students using SWoRD and no instructor grading for assessment
of writing in one university class. Findings from that study indicate that students sometimes regard peer assessment as unfair
and often believe that peers are unqualified to review and assess students’ work. Furthermore, students’ perceptions about
the fairness of peer assessment drop significantly following students’ experience in doing peer assessment. Students’ fairness
perceptions—and drops in those perceptions—are most significantly associated with their perceptions about the extent to which
peers’ feedback is useful and positive. However, students’ perceptions appear to be unrelated to the extent of their revision
work. This research fills a considerable gap in the literature regarding the origin of students’ negative perceptions about
peer assessment, as well as how perceptions influence performance. 相似文献

High-quality measures of instructional practice are essential for research and evaluation of innovative instructional policies and programs. However, existing measures have generally proven inadequate because of cost and validity issues. This paper addresses two potential drawbacks of survey self-report measures: variation in teachers’ interpretation of response scales and their interpretation of survey questions. To address these drawbacks, researchers tested out use of “anchoring vignettes“ in teacher surveys to capture information about teaching practice, and they gathered validity evidence in regard to their use as a tool for adjusting teachers’ survey self-reports about their instructional practices for research purposes, or potentially to inform professional development. Data from 65 teachers in grades 4-9 responding to our survey suggested that vignette adjustments were reliable and valid for some instructional practices more than others. For some instructional practices, researchers found significant and high correlations between teachers’ adjusted survey self-rating, through use of anchoring vignettes, and previous observation ratings of teachers’ instruction, including ratings from several widely-used observation rubrics. These results suggest that anchoring vignettes may provide an efficient, cost-effective method for gathering data on teachers’ instruction. 相似文献

The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.

This paper draws on data from a project undertaken with children (N?=?72) in Mongolia and Zambia. The research is distinctive in bringing together diverse children, ranging from those living on the street to those in mainstream education and involving them in discussions about educational research. Being conscious of critiques of adult-initiated research as well as being influenced by work on participatory action research and research on understanding children's perspectives, we were keen to hear the views of children about research and how research should be carried out. This included enabling children's participation in discussions about potential research areas that could be focused upon as well as discussions about ethical issues and methodology. In this paper we report on our experiences of involving children in discussions about research and explore the numerous insights that the children provided. We conclude that while understanding children's perspectives on research and including children in the research process is important there are many issues which arise from doing so and which need to be reflected upon. These include issues around power and identity, the importance of the context, including local expectations of children as well as children's prior experiences, including how ‘vulnerable’ children are represented. 相似文献

The BIO2010 report provided a compelling argument for the need to create learning experiences for undergraduate biology students that are more authentic to modern science. The report acknowledged the need for research that could help practitioners successfully create and reform biology curricula with this goal in mind. Our objective in this article was to explore how a set of six design heuristics could be used to evaluate the potential of curricula to support productive learning experiences for science students. We drew on data collected during a long-term study of an undergraduate traineeship that introduced students to mathematical modeling in the context of modern biological problems. We present illustrative examples from this curriculum that highlight the ways in which three heuristics—instructor role-modeling, holding students to scientific norms, and providing students with opportunities to practice these norms—consistently supported learning across the curriculum. We present a more detailed comparison of two different curricular modules and explain how differences in student authority, problem structure, and access to resources contributed to differences in productive engagement by students in these modules. We hope that our analysis will help practitioners think in more concrete terms about how to achieve the goals set forth by BIO2010. 相似文献

A group of 21 hard-of-hearing and deaf children attending primary school were trained by their teachers on the production of selected consonants and on the meanings of selected words. Speech production, vocabulary knowledge, reading aloud, and speech perception measures were obtained before and after each type of training. The speech production training produced a small but significant improvement in the percentage of consonants correctly produced in words. The vocabulary training improved knowledge of word meanings substantially. Performance on speech perception and reading aloud were significantly improved by both types of training. These results were in accord with the predictions of a mathematical model put forward to describe the relationships between speech perception, speech production, and language measures in children (Paatsch, Blamey, Sarant, Martin, & Bow, 2004). These training data demonstrate that the relationships between the measures are causal. In other words, improvements in speech production and vocabulary performance produced by training will carry over into predictable improvements in speech perception and reading scores. Furthermore, the model will help educators identify the most effective methods of improving receptive and expressive spoken language for individual children who are deaf or hard of hearing. 相似文献

In this article, we describe an exploratory study of a small-scale, concept-driven, voluntary laboratory component of Introductory Biology at the Massachusetts Institute of Technology. We wished to investigate whether students' attitudes toward biology and their understanding of basic biological principles would improve through concept-based learning in a laboratory environment. With these goals in mind, and using our Biology Concept Framework as a guide, we designed laboratory exercises to connect topics from the lecture portion of the course and highlight key concepts. We also strove to make abstract concepts tangible, encourage learning in nonlecture format, expose the students to scientific method in action, and convey the excitement of performing experiments. Our initial small-scale assessments indicate participation in the laboratory component, which featured both hands-on and minds-on components, improved student learning and retention of basic biological concepts. Further investigation will focus on improving the balance between the minds-on concept-based learning and the hands-on experimental component of the laboratory. 相似文献
