In the first part of this article, the use of Generalizability (G) theory in examining the dependability of concept map assessment scores and designing a concept map assessment for a particular practical application is discussed. In the second part, the application of G theory is demonstrated by comparing the technical qualities of two frequently…

The idea that formative assessments embedded in a curriculum could help guide teachers toward better instructional practices that lead to greater student learning has taken center stage in science assessment research. In order to embed formative assessments in a curriculum, curriculum developers and assessment specialists should collaborate to…

Our project to embed formative student assessments in the Foundational Approaches in Science Teaching curriculum required a close collaboration between curriculum developers at the Curriculum Research & Development Group (CRDG) and assessment developers at the Stanford Educational Assessment Laboratory (SEAL). This was a new endeavor for each…

Given the current emphasis on conducting high-quality experimental studies, it is becoming increasingly important for researchers to accompany their studies with evaluations of the "fidelity of implementation" of the experimental treatments. This article compares the form and extent of an experimental treatment to student learning. The study…

Assessment of and for learning has occupied center stage in education reform, especially with the advent of the No Child Left Behind Federal legislation. This study examined the formative function of assessment--assessment for learning--recognizing that such assessment needs to be aligned, at least in part, with the summative function of…

Formative assessment was hypothesized to have a beneficial impact on students' science achievement and conceptual change, either directly or indirectly by enhancing motivation. We designed and embedded formatives assessments within an inquiry science unit. Twelve middle-school science teachers with their students were randomly assigned either to…
