Evidence-based teaching is a highly complex skill, requiring repeated cycles of deliberate practice and feedback to master. Despite existing well-characterized frameworks for practice-based training in K-12 teacher education, the major principles of these frameworks have not yet been transferred to instructor development in higher educational…

Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students' spoken or written argumentation.…

Graduate teaching assistants (GTAs) play a crucial role in North American colleges. At a mid-Atlantic, land grant institution, GTAs instruct 34,000 undergraduates per semester. Given this scope, GTAs exert a powerful influence on undergraduate learning, yet little is known about their teaching beliefs in relation to their classroom practices. This…

The purpose of this study was to investigate three second-year graduate students' awareness and understanding of the relationships among the "big ideas" that underlie the concept of derivative through modeling tasks and Skemp's distinction between relational and instrumental understanding. The modeling tasks consisting of warm-up,…

This study examined how characteristics of Collaborative Peer Video Analysis (CPVA) events are related to teachers' pedagogical outcomes. Data included 39 transcribed literacy video events, in which 14 in-service teachers engaged in discussions of their video clips. Emergent coding and Statistical Discourse Analysis were used to analyze the data.…

Teacher education students confront the challenging task of acquiring a unique and complex set of skills during their courses. These skills are acquired through the study of education theory together with practical experience in the classroom. Perhaps one of the most important skills that students quickly need to develop is that of reflective…

This dissertation utilized a multiple case study design to explore how advanced learners synthesize information about ill-structured topics when reading-to-learn and reading-to-do on the Web. Eight graduate students provided data in the form of think-alouds, interviews, screen video, digital trails, and task artifacts. Data analysis was based on…

The purpose of this paper is to demonstrate the value of using discourse analysis to understand users' interactions in a scenario-based virtual environment. This study investigated six dyads' synchronous discourses while they worked side-by-side to plan and implement goal-related decisions in a virtual inquiry. The Collaborative Process Analysis…
