Valid and Reliable Science Content Assessments for Science Teachers
Authors: Tretter Thomas R., Brown Sherri, Bush William S., Saderholm Jon C., Holmes Vicki-Lynn
The purpose of this article is to offer the validity and reliability evidence for teacher science content assessments developed as part of the Diagnostic Teacher Assessments of Mathematics and Science (DTAMS) project. It was found that validity was strengthened by systematic synthesis of relevant documents, extensive use of external reviewers, and field tests with 900 teachers during assessment development process. The subsequent results from 4,400 teachers, analyzed with Rasch IRT modeling techniques, offer construct and concurrent validity evidence.

Preservice Teachers’ Research Experiences in Scientists’ Laboratories
Authors: Brown Sherri, Melear Claudia
The study describes an apprenticeship course designed to provide preservice secondary science teachers opportunities to engage in an authentic, extended, open-ended scientific inquiry. The model included placing preservice teachers with scientists in expert/novice roles where each teacher would be actively engaged in constructing knowledge. Findings indicated that participants acquired scientific skills and content knowledge; however, they expressed limited use of these in their classrooms.
