Analyses highlighting the epistemic dimension of students' participation in science have dominated science education literature for the past several years. While most of this literature has focused on how students learn together, the relational nature of these knowledge-building interactions has been under-examined. In response, this paper…

Increasingly, multi-representational educational technologies are being deployed in science classrooms to support science learning and the development of representational competence. Several studies have indicated that students experience significant challenges working with these multi-representational displays and prefer to use only one…

The Teaching for Transformative Experiences in Science (TTES) model is designed to foster transformative experiences (e.g., experiences with science content involving the application of that content in ways that expand perception and value in everyday experience). This study presents a case study of a high school biology teacher learning to…

Clinical interviewing is viewed here as a social interactional pattern in order to examine the nature and limits of the technique as a means of scientific data acquisition. I defend the technique against criticisms that it is ecologically suspect and prone to systematic biases, mainly due to influence of the interviewer on the interviewee or to…

In this article, I propose that at the juncture of disciplines, the mind is involved in at least 3 cognitive activities: overcoming internal monologism or monodisciplinarity, attaining provisional integration, and questioning the integration as necessarily partial. This claim is supported by interview data I collected primarily from faculty…

Presents a case study of third graders' development of place value conceptions to illustrate an approach for documenting students' mathematical development in the social context of the elementary school classroom. Documents the evolution of communal mathematical practices in which students participate and the development of individual…

Evaluated the PREG conceptual model of human question asking. Found the model was sufficient as it accounted for nearly all of the questions produced by students, and was discriminating in that it could identify the conditions in which particular classes of questions are or are not generated.

Five experiments explored a potentially more productive application of educational technology in which an individual learner has the opportunity to develop a social relation with a computer by interacting with an animated pedagogical agent. Results support the introduction of interactive pedagogical agents to promote meaningful learning in…

This study analyzes the interpretive activities of scientists related to familiar and unfamiliar graphs. The analyses show that when scientists were familiar with a graph, they read it transparently and thereby leapt beyond the material basis to the thing the graph is said to be about. In contrast, when scientists were less familiar with the…
