Interpret with Caution: COPUS Instructional Styles May Not Differ in Terms of Practices That Support Student Learning.

There is a growing need for valid and reliable measures to monitor the efficacy of undergraduate science, technology, engineering, and mathematics (STEM) reform initiatives. The Classroom Observation Protocol for Undergraduate STEM (COPUS) is a widely used tool originally designed to measure the presence of overt instructor and student behaviors. It has subsequently been used to characterize instruction along a continuum from didactic to student centered, and more recently to categorize instruction into one of three styles.

Drawing on student knowledge of neuroanatomy and neurophysiology.

Drawings are an underutilized assessment format in Human Anatomy and Physiology (HA&P), despite their potential to reveal student content understanding and alternative conceptions. This study used student-generated drawings to explore student knowledge in a HA&P course. The drawing tasks in this study focused on chemical synapses between neurons, an abstract concept in HA&P.

Students' illustrations of the human nervous system as a formative assessment tool.

The purpose of this study was to explore students' knowledge and learning of the human nervous system (HNS) in an introductory undergraduate Human Anatomy and Physiology course. Classroom observations, demographic data, a preinstructional unit test with drawings, and a postinstructional unit test with drawings were used to identify students' overall knowledge and learning during the unit of study. Quantitative and qualitative analysis indicate that students have an initially poor understanding of the nervous system with many prevailing alternative conceptions.

Comparison of views of the nature of science between natural science and nonscience majors.

Science educators have the common goal of helping students develop scientific literacy, including understanding of the nature of science (NOS). University faculties are challenged with the need to develop informed NOS views in several major student subpopulations, including science majors and nonscience majors. Research into NOS views of undergraduates, particularly science majors, has been limited.
