This study is the third in a line of investigations that examines pre-service teachers' conceptions of nature of science (NOS) and the translation of those conceptions into classroom practice. The purpose of the present study was to delineate the effectiveness of an intervention designed to facilitate pre-service teachers' inclusion of NOS in their classroom teaching. Four factors were identified as most influential in participants' teaching efforts: (1) knowledge of NOS, (2) knowledge of subject matter, (3) pedagogical knowledge, and (4) intentions towards teaching NOS. Intentions were the most critical factor. Participants, regardless of NOS views or science background, did not teach in accordance with their NOS views if they had not internalized the importance of teaching NOS. Those with strong intentions to address NOS explicitly were more successful. Those participants with strong intentions, well-developed NOS views, and extensive knowledge of science content were most successful in their instruction. Implications for the development of pedagogical content knowledge for NOS are discussed.
