Much research in educational technology has focused mainly on how the technology supports student learning. Research on what teachers need to know in order to appropriately incorporate technology into their teaching has been limited because of the lack of theoretical grounding for understanding teachers' cognitive process of technology integration…

Models and modeling are a major issue in science studies and in science education. In addressing such an issue, we first propose an epistemological discussion based on the works of Cartwright (1983, 1999), Fleck (1935/1979), and Hacking (1983). This leads us to emphasize the transitions between the abstract and the concrete in the modeling…

The evolution of human-computer interaction design (HCID) over the last 20 years suggests that there is a growing need for educational scholars to consider new and more applicable theoretical models of interactive product design. The authors suggest that such paradigms would call for an approach that would equip HCID students with a better…

This investigation delineates a multi-year action research agenda designed to develop an instructional model for teaching the nature of science (NOS) to preservice science teachers. Our past research strongly supports the use of explicit reflective instructional methods, which includes Thomas Kuhn's notion of learning by ostention and treating…

This article explores how students' mathematical representations can be used as formative assessments. We introduce a framework for teaching and learning that integrates representations as instructional and assessment tools, and illustrate these uses of student representations with reference to a study conducted with 250 5th-grade students. This…

Material from the literature and from current research on teacher thinking is used to explore models of teachers' interactive thinking and relationships among teachers' practical theories of teaching, interactive thinking, and classroom action. (IAH)
