title = "Examining teachers{\textquoteright} support of students{\textquoteright} learning of dynamic geometry in a CSCL environment",
abstract = "We report on a case study of a teacher{\textquoteright}s implementation of a CSCL project to understand how teachers{\textquoteright} pedagogical interventions influence students{\textquoteright} mathematical reasoning in a collaborative, dynamic geometry environment. A high school teacher engaged a class of students in the Virtual Math Teams with GeoGebra environment (VMTwG) to solve geometric tasks that the research team designed to promote collaboration and mathematical justification. The VMTwG allows users to share both GeoGebra and chat windows to engage in joint problem solving. Our analysis of the teacher{\textquoteright}s implementation and his students{\textquoteright} interactions in VMTwG shows how his technological and pedagogical content knowledge, revealed through his instructional interventions, shaped his students{\textquoteright} movement among empirical explorations and deductive justifications.",
