The authors provided several direct quotes to support these claims. The following quote is representative, ‘‘I find that my teaching has improved, I find that I understand more about what I’m doing, why I’m doing things, and I find that’s been an improvement’’ (p. 246). Note that although the researchers provided a teacher’s self-reported data that indicated change in practice, the teacher provided no specific information about the nature of changes in practice or thinking. This general trend was pervasive in the research studies, whether included in or excluded from this literature review. Instead of descriptions of specific changes in pedagogy, the researchers reported that teachers perceived their practices had changed. What the researchers typically provided was more specific information on how the teaching culture changed as a result of teachers’ participation in a PLC.
