The goal of the Department of Biological Sciences faculty was to evaluate how effectively our undergraduate biology program supports the goals and intended outcomes of our department and institution. Student responses in written assessment tests have provided the foundation of this evaluation. Each semester questions were selected by a…

Studies of test dimensionality indicate that many large-scale science assessments measure multiple dimensions. These findings have reinforced the perspective that science achievement is an inherently dynamic process and that there is benefit in reporting subscores in science. A limitation with some of these studies is that they fail to indicate…

This study focuses on how the treatment effects of a teacher professional development initiative in science differed by school capacity. In other words, the authors are primarily concerned with treatment effect heterogeneity. As such, this paper complements ongoing evaluation of the average treatment effects of the initiative over time. The…

Argues that science educators often face the problem of abnormal distributions when conducting large-scale assessments or evaluating national curriculum projects that require complex sampling plans. Examines the precision of science test scores. (DDR)

This report discusses the purposes and nature of various forms of assessment that can be used to enhance, support, and monitor the progress of science learning in elementary school classrooms. Chapters included are: (1) "Introduction" (describing assessment priorities); (2) "Issues in Assessment" (discussing validity, correspondence between…
