Elementary Pre-service Teachers' Perceptions of Assessment Tasks to Measure Content Knowledge for Teaching about Matter

This study explores how 79 elementary pre-service teachers evaluate the importance and pertinence of assessment tasks, designed to elicit information about content knowledge for teaching (CKT) about matter—a foundational topic for physical science. Drawing on a cognitive perspective and using think-aloud procedures, we had the participants answer different assessment items that described teaching scenarios related to elementary science instruction for topics such as properties of matter, changes in matter, the model of matter, and conservation of matter. We aimed to explore (1) how familiar pre-service teachers felt these task scenarios were in regards to their (pre-service) teaching experience and (2) how important they considered these task scenarios for the work of elementary teachers.
