Collaborating to enhance student reasoning: Frances' account of her reflections while teaching chemical equilibrium

Many researchers report that teachers' pedagogies often reflect non-constructivist referents, however less research reports on means of assisting teachers to become more constructivistly oriented. This paper reports on a teacher's changing perceptions during collaborative, two-year interpretive research involving two researchers, herself, and her students. The researchers collaborated with the teacher to promote students' theory-evidence coordination and use of word explanations, with an emphasis on developing and critiquing chemical equilibrium theory using experimental data. As the collaboration proceeded the teacher's beliefs and practice became increasingly focussed on students' reasoning and their discussion of ideas related to experimental data. The teacher reported benefits for herself and for her students as a consequence of this change. Key factors in relation to this change included researchers' modelling of target practices, and changes in the teacher's (a) perception of her students' abilities, (b) beliefs in relation to constructivism, and (c) understanding of chemistry concepts.
