Abstract: | Part of the work of teaching elementary science involves evaluating elementary students' work. Depending on the nature of the student work, this task can be straightforward. However, evaluating elementary students' representations of their science learning in the form of scientific models can pose significant challenges for elementary teachers. To address some of these challenges, we incorporated a modeling-based elementary science unit in our elementary science teaching methods course to support preservice teachers in gaining knowledge about and experience in evaluating students' scientific models. In this study, we investigate the approaches and criteria preservice elementary teachers use to evaluate elementary student-generated scientific models. Our findings suggest that with instruction, preservice elementary teachers can adopt criterion-based approaches to evaluating students' scientific models. Additionally, preservice teachers make gains in their self-efficacy for evaluating elementary students' scientific models. Taken together, these findings indicate that preservice teachers can begin to develop aspects of pedagogical content knowledge for scientific modeling. |
