This case study examined teachers' on-the-fly formative assessment conversations, that is, how teachers collect information from students' thinking and use that information to support their learning during teacher-student interactions. Previous studies have typically analysed whole-class discussions on the level of speaking turns, and have…

This multiple case study focused on the implementation of a computer-aided design (CAD) simulation to help students engage in engineering design to learn science concepts. Our findings describe three case studies that adopted the same learning design and adapted it to three different populations, settings, and classroom contexts: at the…

Teachers' professional knowledge is assumed to be a key variable for effective teaching. As teacher education has the goal to enhance professional knowledge of current and future teachers, this knowledge should be described and assessed. Nevertheless, only a limited number of studies quantitatively measures physics teachers' professional…

This paper reports on a case study of an immersive and integrated multi-instructional approach (namely computer-based model introduction and connection with content; facilitation of individual student exploration guided by exploratory worksheet; use of associated differentiated labs and use of model-based assessments) in the implementation of…

Describes the construction of assessments on inclines and friction from blueprints--or shells--which address the tasks of planning, hands-on, analysis, and application. Examines the reliability and validity of the assessments as well as the comparability of the assessments generated with the shell. Contains 48 references. (Author/WRM)

Suggests improvements for implementation of the "Views on Science-Technology-Society" instrument. Analyzes the scaling properties of some scoring procedures within the unique response model and discusses ways to produce "best fidelity" measurements. Presents a multiple-response model that could take advantage of all the…
