This paper examines the effectiveness of adding an online component to the general chemistry laboratory in which students view prelaboratory instructional materials through online videos prior to completing general chemistry laboratory activities. Using a quasi-experimental design, we compared the performance of 1089 general chemistry students who…

This study examined the effect of different anatomic representations on student learning in a human anatomy class studying the muscular system. Specifically, we examined the efficacy of using dissected cats (with and without handouts) compared with clay sculpting of human structures. Ten undergraduate laboratory sections were assigned to three…

Dissections of single species (e.g., fetal pig) are a common student learning activity in introductory biology courses. Such dissections demonstrate location of anatomical parts and provide dissection practice but provide less opportunity for student critical thinking, numeracy and demonstration of the scientific method. A comparative anatomy lab…

Active learning is a teaching methodology with a focus on student-centered learning that engages students in the educational process. This study implemented active learning techniques in an orthopedic assessment laboratory, and the effects of these teaching techniques. Mean scores from written exams, practical exams, and final course evaluations…

The effectiveness of two different laboratory techniques is compared to teach students majoring in science in a general chemistry laboratory. The results demonstrated that student laboratory activities with computer-interface systems could improve student understanding.

A retrospective analysis examines the relationships between formative assessments and exam grades in two undergraduate geoscience courses. Pair and group-work grades correlate weakly with individual exam grades. Exam performance correlates to individual, weekly online assessments. Student attendance and use of assessment feedback are also…

Bioscience staff and students at Glasgow University in session 2005-06 were questioned on their attitudes to animal uses in higher education, as follow-up to a similar survey 20 years before. Disapproval by students of animal use was generally reduced compared to 20 years ago, but students remained in a "moral bind", recognising the…
