A Mathematics Teacher's Learning Through Reflection-in-Action

In this study, I investigated the learning of one secondary mathematics teacher through observations in two class periods. I analyzed his learning in relation to the communities of practice framework and found reflection-in-action was instrumental in his learning. I characterized the teacher’s reflection-in-action with the descriptors: developmental, hypothetical, and experimental. Developmental reflection-in-action involved the development of new understandings or practices. Hypothetical reflection-in-action involved imagined future situations. Experimental reflection-in-action involved repeated trials. I propose that the use of a cycle of reflection-in-action in professional communities may have a positive impact on teacher learning.
