This study describes the ways in which 36 preservice elementary teachers (PSETs) incorporated text into slides (n = 158) they designed for use with K-5 students during whole-group mathematics instruction. A qualitative content analysis was conducted to determine the extent and purposes for which the PSETs used slide text. Overall, 80% of slides…

This study investigates how preservice elementary teachers (PSTs) engage and reflect on two science disciplinary practices: engaging with representations and engaging in evidence-based arguments. In the context of elementary science, teachers blend multiple practices across curricular topics and instruction. However, studies of teachers' use of…

Prospective elementary teachers must understand fraction division deeply in order to meaningfully teach this topic to their future students. This paper explores the nature of the subject content knowledge of fraction division possessed by a group of Taiwanese prospective elementary teachers at the beginning of their mathematics methods course. The…

This paper describes the genesis and purpose of our geometry methods course, focusing on a geometry-teaching technology we created using NVIDIA[R] Chameleon demonstration. This article presents examples from a sequence of lessons centered about a 3D computer graphics demonstration of the chameleon and its geometry. In addition, we present data…

The purpose of this study was to explore the effect of providing preservice teachers the opportunity to collect real data in a science methods inquiry investigation and using the data, design data displays in their mathematics methods course. The research questions focused on how preservice teachers' understandings of data displays, research…
