Learning About Teaching Science: Improving Teachers' Practice Through Collaborative Professional Learning, Sarah E. Cloutier

Electronic Thesis and Dissertation Repository

This single, descriptive qualitative case study provides a snapshot of elementary teachers and their school principal’s multiple and competing views about personal and contextual factors affecting teacher engagement in collaborative professional learning (CPL) related to science education within the school environment. This study was viewed through the lens of Situated Learning Theory primarily by Lave and Wenger (1991) because viewing knowledge as situated has implications for understanding teacher learning and the design of instructional activities.

Data were collected from three female elementary teachers and their school principal in Ontario for a period of six months. The data included: five principal …

Exploring And Training Spatial Reasoning Via Eye Movements: Implications On Performance, Victoria A. Roach

Electronic Thesis and Dissertation Repository

This dissertation sought to determine if eye movements could serve as an indicator of success in spatial reasoning, and if eye movements associated with successful completion could be applied to strategically improve spatial reasoning.

Using the line images of Shepard and Metzler, an electronic test of mental rotations ability (EMRT) was designed. Two versions of the test were created, allowing for both a timed (6 seconds per question) and untimed testing environment. Four experiments were designed and completed to relate mental rotation ability (MRA) scores from the EMRT, to patterns in chrononumeric and visual salience data. In each experiment, participants …

Using Worked-Out Examples Of Written Explanation For Writing-To-Learn In Evolutionary Biology, Amy M. Yu

Electronic Thesis and Dissertation Repository

Content learning can be enhanced through writing-to-learn. Research into cognitive load theory suggests that the use of backwards faded, worked-out examples increases schema acquisition and concept transfer. However, these effects have not yet been demonstrated for writing-to-learn, particularly for the conceptual understanding of evolution. The effects of two writing conditions were investigated in a pre-test post-test quasi-experimental design. Groups in two conditions wrote explanations of evolution using six Darwinian principles: students in the completion condition completed backwards faded, worked-out examples of explanations; students in the problem solving condition wrote full explanations, thought to require means-end problem solving. The dependent variables …
