A procedure-based observational scoring system and a notebook completed by students were evaluated as science assessments for 41 fifth grade students experienced in hands-on science and 55 fifth grade students inexperienced in hands-on science. Results suggest that notebooks may be a reasonable, although less reliable, surrogate for observed…

The role of performance assessments in making cognitive activity apparent to teachers and students was studied through descriptions of the cognitive activity of 31 fifth-grade students. Differences while carrying out a science performance assessment reveal critical differences between those who think and reason well with their knowledge of…

Examined fifth-grade teachers' grouping practices for hands-on science instruction. Found that teachers tended to form heterogeneous groups in relation to the composition of their classrooms, whereas students tended to form homogeneous groups with respect to gender, ethnicity, and achievement. Some classroom compositions severely constrained…

The degree to which performance assessments meet their dual mandate to evaluate student learning and inform instructional practice is not adequately addressed through traditional concerns for reliability and validity. A possible approach is suggested for examining the cognitive activity students engage in during a performance assessment. The…
