of ethnographic data. The tools Gilmer employs as she hones her teaching skills include collaborative learning and technology. She views the classroom through various theoretical perspectives: social constructivism, cultural-historical activity theory, and a theory that involves the dialectic between the structure of the learning environment and the agency of the learners (a group among whom she includes herself). She provides a wealth of autobiographical detail as well as the results of her action research, which followed up on its original subjects after an interval of 11 years, to see what impact her course had on their professional growth. Above all, this volume is proof of what can be achieved in education when teachers are as interested in the process of learning as they are in their subject itself.
