Graphing is an important tool for seeing patterns, analyzing data, and building models of scientific phenomena. Teachers of elementary school children use graphs to display data but rarely as tools for analyzing or making sense of data (Coleman, McTigue, & Smolkin, 2011). We provide a set of lessons that guide preservice elementary school teachers to analyze their conceptions about graphing and use graphing to (a) see patterns in data, (b) discuss and analyze data, (c) model scientific phenomena, and (d) teach and assess inquiry-based science. Examples are adduced for how we guided and supported preservice elementary teachers in their conceptual understanding and deeper use of graphing.
Despite a large body of research on effective discussion in science classrooms, teachers continue to struggle to engage all students in such discussions. Whole-class discussions are particularly challenging to facilitate effectively and, therefore, often have a teacher-centered participation pattern. This article describes the Critical Response Protocol (CRP), a tool that disrupts teacher-centered discussion patterns in favor of a more student-centered structure that honors students’ science ideas. CRP originated in the arts community as a method for giving and receiving feedback to deepen critical dialog between artists and their audiences. In science classrooms, CRP can be used to elicit student ideas about scientific phenomena and invite wide participation while reducing the focus on “correct” responses. In this article, we describe our use of CRP with preservice science teachers. We first modeled the CRP process as it would be used with high school students in science classrooms, then discussed pedagogical considerations for implementing CRP within the preservice teachers’ classrooms. We conclude this article with a discussion of our insights about the opportunities and challenges of using CRP in science teacher education to support preservice teachers in leading effective whole-class discussion and attending to inclusive participation structures.
