Scholars have acknowledged abstraction as the keystone of computational thinking. To foster K-12 students' computational thinking and STEM literacy, students' ability to think abstractly should be enhanced. However, the existing…

Considers well-structured problems versus ill-structured problems and presents models for how learners solve them, as well as models for designing instruction to support problem-solving skill development. Information processing theories of learning, an emerging theory of ill-structured problem solving, constructivist learning, and situated…

This theory-based article describes how data analysis tools, simulations, and modeling software, when used in the proper instructional contexts, provide young learners with rich intellectual environments for inquiry in science learning. Highlights include inquiry learning; abilities of learners; and the integration of technology within classroom…
