Non-rigid spatial thinking, or mental transformations where the distance between two points in an object changes (e.g., folding, breaking, bending), is required for many STEM fields but remains critically understudied. We developed and tested a non-rigid, ductile spatial skill measure based on reasoning about knots with 279 US adults (M = 30.90,…

Augmented Reality (AR) revolutionizes educational approaches by providing an immersive experience that superimposes virtual 3D elements onto the physical environment. This integration of virtual and real worlds addresses the challenge of understanding abstract concepts by enabling three-dimensional visualization and interaction. This study aims to…

Learning content-specific vocabulary is critical for students especially in content areas such as science. However, direct vocabulary instruction is lacking in many classrooms. This case study examined vocabulary instructional strategies within a 6th grade science classroom. The following questions were addressed: (1) What science vocabulary…

This study, a sub-study of a National Science Foundation (NSF) funded research project, applies a modified strategy of the U[superscript 2]MC for an eight-week afterschool robotics curriculum to promote upper elementary students' computational thinking in the second grade. Twenty-one students in second grade participated in a Life on Mars project…

The importance of culture and social interactions in disciplinary learning and language development within specific social practices and contexts is now an agreed-upon notion in the science education literature. In a pivotal article in 1990, Lemke introduced the idea of manual-technical operations as one of four modes making up the "hybrid…

STEM instruction often uses visual representations. To benefit from these, students need to understand how representations show domain-relevant concepts. Yet, this is difficult for students. Prior research shows that physical representations (objects that students manipulate by hand) and virtual representations (objects on a computer screen that…
