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…

This article focuses on how the representational properties of manipulatives affect the strategies children employ in problem solving. Two studies examined the effect of physical materials on 4-7-year-old children's problem solving strategies in a numerical (i.e., additive composition) task. The first study showed how children not only identified…

In order to better understand how to design hands-on child-computer interaction, we explore how different styles of interaction facilitate children's thinking while they use their hands to manipulate objects. We present an exploratory study of children solving a spatial puzzle task. We investigate how the affordances of physical, graphical…

Synergistic psychology has been proposed as a meta theory for synthesizing different psychological theories into an explanation of how social, cognitive, and biological factors interact in human behavior. The basic theoretical assumption in synergistic psychology is that internalized social interactions become higher mental functions that regulate…

The purpose of this study was to assess the effectiveness of two generative learning strategies, concept maps and manipulation of objects, and to determine if either works better with individual learners or in cooperative learning groups. A total of 80 sixth-grade students in science education were randomly assigned to group or individual…
