The focus of this study is students’ learning with a Connected Chemistry unit, CC1 (denotes Connected Chemistry, chapter 1), a computer-based environment for learning the topics of gas laws and… (More)

This study lies at an intersection between advancing educational data mining methods for detecting students’ knowledge-in-action and the broader question of how conceptual and mathematical forms of… (More)

Connected Chemistry (named CC1 to denote Connected Chemistry Chapter 1) is a computer-based environment for learning the topics of gas laws and kinetic molecular theory in chemistry. It views… (More)

We investigate students’ strategies in exploring computer models and the way these relate to the underlying mathematical behavior of the model, and to prior knowledge in the domain. In the Modeling… (More)

There has been a body of emerging research describing students’ understanding of complex systems. This research has primarily studied students understanding of complex phenomena in science. However,… (More)

This study investigates young children’s perspectives in explaining a selfregulating mobile robot, as they learn to program its behaviors from rules. We explore their descriptions of a robot in… (More)

How can we characterize the ways in which students explore computer models to find needed information? Do the types of goals that guide their exploration affect these characteristics? Is the path of… (More)

How can we characterize the ways in which students explore computer models to search for information? In the Modeling Across the Curriculum project, we enable students’ exploration of computer models… (More)

This paper presents Frog Pond, an interactive code-first learning environment about biological evolution. We deployed Frog Pond as part of a six-day curricular unit on natural selection implemented… (More)
