Potential teachers' appropriate and inappropriate application of pedagogical resources in a model‐based physics course: A “knowledge in pieces” perspective on teacher learning

Abstract

We used a “knowledge in pieces” perspective on teacher learning to document undergraduates' pedagogical resources in a model‐based physics course for potential teachers. We defined pedagogical resources as small, discrete ideas about teaching science that are applied appropriately or inappropriately in specific contexts. Neither right nor wrong, all pedagogical resources can be used to build toward a more sophisticated pedagogical stance. We collected three kinds of data across this 11‐week course: videotapes of class sessions, undergraduates' written assignments and projects, and individual interviews. We qualitatively analyzed these data for pedagogical resources that undergraduates applied both appropriately and inappropriately to make sense of the large concept of model‐based science instruction. We identified four such resources: (1) the teacher's role is to provide the right answer, (2) guiding students is less certain than telling them (the right answer), (3) a good model includes scientific terms, and (4) children are creative thinkers. We examined the ways potential teachers' inappropriate application of these four pedagogical resources interfered with their attempts to understand science teaching through modeling. We also explored how seemingly problematic small ideas about teaching were applied appropriately toward a more nuanced description of model‐based science instruction. In our discussion and implications, we recommended ways content course instructors and science education researchers can identify and build from potential teachers' pedagogical resources to help them better understand the large concept of model‐based science instruction. © 2013 Wiley Periodicals, Inc.

Learning from avatars: Learning assistants practice physics pedagogy in a classroom simulator

“…The use of a classroom simulator to practice pedagogical skills is grounded in this perspective, and represents a new modality of clinical practice. Harlow and colleagues have described pedagogical resources as "small, discrete ideas about teaching… activated in specific contexts to understand the teaching and learning of science" [42] (pg. 1099).…”

Assessing the interactivity and prescriptiveness of faculty professional development workshops: The real-time professional development observation tool

“…Hammer et al [75] describe the general process by which people relate their current situation to familiar past experiences as framing or resource activation, and several studies have shown that students' engagement and apparent abilities are influenced by the framing they adopt [76][77][78]. Similarly, PD researchers have shown that instructors approach teaching in context-dependent ways [79][80][81][82][83], which lends weight to the idea that the framing that faculty take up within workshop settings plays a role in what they gain from their participation. Although faculty may quietly or vocally contest a workshop leader's instructions, every participant will adopt some framing that influences their thinking during the session, regardless of whether or not the workshop leader guides them towards a particular orientation.…”

Role-plays for preparing physics teaching assistants and learning assistants

“…A previously-identified TA belief is that "guiding students is less certain than telling them (the right answer)" because it introduces unnecessary uncertainty into the learning process [12]. Researchers have established that instructors who practice guiding students have less negative attitudes toward instructional reform and increased buy-in to inquirybased learning (IBL) [1].…”
