A similar result is found by others investigating the impact of an explicit/reflective approach to NOS learning on preservice teachers participating in a research apprenticeship (Schwartz, Lederman, & Crawford, 2004). In this study, 11 of 13 participants showed gains in NOS understandings based on pre and post responses to an open-ended questionnaire and follow up interviews. All of these participating preservice teachers were able to link their NOS understandings to their specific research experiences. The authors suggest that these changes were due to participation in seminars and journaling activities designed to explicitly address target NOS outcomes. An interesting finding of this research is that the context of research itself seemed to play less of a role in impacting NOS perspectives than did the seminars and the journaling respectively. It is also worth mentioning that the preservice teachers who were most able to reflect in this study were those that viewed themselves as outsiders looking in to the practice of science during the process of reflection. This is noteworthy in that it seems to suggest that the process of enculturation into the practice of science and subsequent identity formation as a scientist may actually hinder the reflective process. In contrast to this perspective, Richmond and Kurth (1999) document increased conceptions of NOS when participants in research apprenticeships view themselves as insiders in working science labs. We agree with this latter perspective and believe that a desirable feature of research apprenticeships is the degree which participants can view themselves as working members within a culture of practice. Such a transition from outside to inside the practice of science actually supports notions of reflection in the midst of practice as opposed to reflection on past experiences (Schön, 1983; 1987).
