Investigating the Development of Preservice Science Teachers' Nature of Science Instructional Views Across Rings of the Family Resemblance Approach Wheel

While much is known about teacher learning of nature of science (NOS) concepts, less is known about how teachers develop an understanding of how to effectively teach NOS or how instructional views might differ across levels of the Family Resemblance Approach (FRA) wheel. Therefore, this study investigated the NOS instructional views related to different levels of the FRA wheel of preservice secondary science teachers as they completed a semester-long NOS course. At four times during the semester, data was collected through written documents and interviews about NOS instructional views. Participant NOS instructional views were evaluated in terms of three aspects of NOS teaching: explicit, reflective, and role of context (McComas et al., 2020). In terms of the explicit and reflective components of NOS instruction, participants generally progressed from utilizing inaccurate representations of NOS to inclusion of accurate implicit messages, and finally to explicit reflective instruction often mimicking course activities. As the semester progressed, their questioning also moved toward targeting more specific NOS aspects. As far as the role of context, participants moved from treating NOS as its own topic to a more embedded approach. Other findings include that preservice teachers tended to use more abstract and contextualized activities for social institutional aspects of NOS as opposed to concrete and moderately contextualized activities for cognitive-epistemic NOS. Features of the NOS course may account for some aspects of the learning progressions observed.

Automated summary

This study explored the development of instructional views on nature of science (NOS) concepts among preservice secondary science teachers during a semester-long NOS course. The findings revealed that teachers' instructional views progressed from utilizing inaccurate methods to incorporating accurate implicit messages, and finally to explicit reflective instruction. Additionally, teachers shifted from treating NOS as a separate topic to adopting an embedded approach in their teaching.
