Resumen de Effective Use of Demonstration Assessments in the Classroom Relative to Laboratory Topics.

David T. Pierce, Thomas W. Pierce

• Demonstration assessment is an effective pedagogical tool for improving the learning of concepts in introductory chemistry classes. However, in apparent contrast to the learning cycle paradigm, a differential analysis of test-question responses showed that students' improvements were not as evident when the concepts introduced in lecture-based demonstration assessments were later reinforced in an accompanying laboratory. These findings should help instructors to more effectively target this beneficial yet demanding form of classroom assessment.
