Re-examining the relationship between three-dimensional science and engineering knowledge and student interest: a mixed methods study

Abstract Now more than ever, the world needs citizens comfortable with interdisciplinary problem- solving in Science, Technology, Engineering, and Mathematics (STEM) to address global environmental and health challenges, including extreme weather, habitat destruction, and air pollution, among others. However, many countries report an insufficient number of individuals with experience in STEM problem solving. In addition, recent research indicates low interest and knowledge in STEM fields. Government organizations, corporations, and nonprofits ask for pre-university STEM education that increases student interest and knowledge in STEM fields. In this mixed-methods study, we explored a potential relationship between interest and three-dimensional (3D) science and engineering knowledge. We analyzed student surveys, classroom artifacts, and teacher interviews to explore student scores and self-proclaimed interest. Results revealed six multi-faceted profiles, with all students reporting average or high interest and scoring low, average, or high on the 3D science and engineering assessment. In addition, four extreme student cases were selected to illustrate and articulate some of the complexities associated with possible linkages between 3D science and engineering knowledge and interest. Our results suggest that reciprocity between interest and knowledge development is more nuanced and complex than a simple correlation or relationship might suggest.
