Physical manipulatives enhanced knowledge acquisition by engaging learners in hands-on experiences that supported spatial reasoning. These tools allowed learners to see, touch, and manipulate objects, improving their ability to mentally rotate and visualize structures. This study challenged the assumption that most learners are purely visual by…

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,…

A study was designed to determine the effects of various ball sizes on children's catching ability and to examine the results as a between- and within-group factor. It was believed that the use of the two-test design would help to establish the validity of past and future tests of this nature. The between-subjects design group consisted of 48…

A resource and activity guide for the developmentally disabled that focuses on fine motor skills is presented. Attention is directed to fine motor behavior during the first year (vision, grasp, and release and reaching), and behaviors developing at 13 months (the interaction of fine motor and cognitive skills). An introductory section considers…
