Lectures are often thought of in terms of information transfer: students (do not) "get" or "construct meaning of" what physics professors (lecturers) say and the notes they put on the chalkboard (overhead). But this information transfer view does not explain, for example, why students have a clear sense of understanding while they sit in a lecture…

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students' interests in participating in opportunities to do real science? What are the discursive "resources" they draw on to introduce authentic science to students? The purpose of…

Consists of a metalogue between two authors in which critical issues associated with peer review are identified. Highlights theory and practices that are salient to the continued improvement of science education. (DDR)

Reports on learning when engaged in a four-month experience of co-teaching a water unit in a seventh-grade classroom. Suggests that co-teaching allows for a mode of learning that is not captured by Schon's notions of reflection-in-practice and reflection-on-practice. Concludes that co-teaching, as co-learning, is praxis. Contains 26 references.…

Microanalyzes graph use in lectures drawn from artifacts compiled from videotaping all lectures and seminars in a 13-week ecology course. Focuses on both the text and the gesture-related references made in the reading of a graph in an ecology lecture. Contains 36 references. (DDR)

Investigates the relationship between students' views of the nature of scientific knowledge and their own learning of physics, and the evolution of this relationship over time. Uses two intensive case studies to illustrate students' views over time. Discusses the changes in students' views concerning the nature of scientific knowledge and the…
