Promoting Understanding of Several Elements of Nature of Science Using an Analogy: A Tangram Activity

Developing a proper view of the nature of science (NOS) amongst teachers and students has been the goal of science education for decades. This article discusses an innovative activity designed for training preservice science teachers on NOS. We endorse an approach according to which several aspects of NOS can be explicitly discussed and explained. This activity is an extended version of a tangram activity introduced by Choi (2004). Aside from introducing NOS elements covered by Choi, our tangram activity also introduces the following elements: (1) theories are valid products of science, (2) the role of subjectivity and bias in science, (3) the importance of scientific community in science, (4) prediction is part of science, and (5) creativity and imagination are important in science. The activity can be used decontextualized (i.e., as a stand-alone lesson) in science methods classes, but it also has high potential to be contextualized within content related to the history of science. In this article, we provide procedures for using an analogy activity (the tangram activity) and explain how to connect each part to NOS elements. This activity was tested successfully in several science methods courses, a NOS course, and two professional development workshops.

The Home Inquiry Project: Elementary Preservice Teachers’ Scientific Inquiry Journey

by Mahsa Kazempour, Penn State University (Berks Campus)

This article discusses the Home Inquiry Project which is part of a science methods course for elementary preservice teachers. The aim of the Home Inquiry Project is to enhance elementary preservice teachers’ understanding of the scientific inquiry process and increase their confidence and motivation in incorporating scientific inquiry into learning experiences they plan for their future students. The project immerses preservice teachers in the process of scientific inquiry and provides them with an opportunity to learn about and utilize scientific practices such as making observations, asking questions, predicting, communicating evidence, and so forth. Preservice teachers completing this project perceive their experiences favorably, recognize the importance of understanding the process of science, and reflect on the application of this experience to their future classroom science instruction. This project has immense implications for the preparation of a scientifically literate and motivated teacher population who will be responsible for cultivating a scientifically literate student population with a positive attitude and confidence in science.
