Three alternative approaches to assessment of exam responses were applied in an undergraduate biochemistry course. First, phenomenography was used to categorize written exam responses into an inclusive hierarchy. Second, responses to the same question were similarly categorized according to the Structure of Observed Learning Outcome (SOLO)…

The use of assessment methods is a widely discussed topic in education. Exams that are commonly used, however, may not necessarily assess student understanding at a high cognitive level. By implementing alternative assessment methods, instructors can influence student learning. Portfolio-based assessment (PBA) is a purposeful collection of student…

Science literacy involves knowledge of both science content and science process skills. In this study, we describe the Assessment of Critical Thinking Ability survey and its preliminary application to assess the critical thinking skills of undergraduate students, graduate students, and postdoctoral fellows. This survey is based on a complex and…

This article explores the problem of assigning grades to students engaged in nontraditional activities, especially scientific inquiry. We suggest using scoring rubrics to guide students in their work and to assist teachers with grading. We present the steps involved in the construction of rubrics, and we show sample rubrics. (Contains 5 figures.)

Describes an approach to evaluating students in a seminar-style science course that involves students in the design of the assessment instrument and defense of their own performance using the instrument, taking students' performance evaluation to a level beyond measuring learning and teaching effectiveness to self-reflection and critique.…
