Students in a junior- and senior-level Anatomy and Physiology course have the opportunity to correct missed exam questions ("regrade") and earn up to half of the original points missed. The three objectives of this study were to determine if: (a) performance on the regrade assignment was correlated with scores on subsequent exams, (b)…

Studying physics for nonphysics majors at college level is usually a process of learning new problem-solving skills and sometimes seems a frustrating experience. In an attempt to provide students with more learning resources, online homework was required to supplement the instruction. This study reveals the role of the online homework assignments…

Peer educators can be a powerful addition to classroom learning environments. Traditionally, the university science teaching model relies on graduate teaching assistants (GTAs) to provide instruction in laboratory class sessions, but there is increasing evidence that undergraduate TAs (UTAs) can fill an equivalent role. A comparison of student…

How can science instructors prepare students for the statistics needed in authentic inquiry labs? We designed and assessed four instructional modules with the goals of increasing student confidence, appreciation, and performance in both experimental design and data analysis. Using extensions from a just-in-time teaching approach, we introduced…

Traditional lectures have come under increasing criticism as research indicates lectures may be less effective in achieving learning outcomes than other teaching methods. Student engagement and success can potentially be improved by changing traditional lectures to instructional methods using active learning techniques. Active learning refers to…

Asserts that the scientific literacy of the average person can be evaluated adequately only with a definition that involves thinking processes and ignores test-taking skills. (PR)

Describes how one teacher and 46 general chemistry students used portfolios as part of the evaluative process. Argues that any worthwhile assessment must address questions about the inevitable impact of testing on students and their learning. (PR)

Many students fail to integrate biological knowledge into larger conceptual frameworks. Although textbooks and lectures in general biology courses emphasize major concepts, when students respond to questions, they often appear to be randomly grasping at disconnected sound bites of biological knowledge. The knowledge they have accumulated does not…
