"MyScience" is a primary science education initiative in which being in a community of practice is integral to the learning process. This paper describes the ongoing journey to date of eight primary teachers from three primary schools who actively participated in "MyScience" over an extended period. Their views of interactions with mentors and students were analysed, in part, using attributes associated with both "communities of practice" and the "nature of science". Findings reveal teachers' new understandings about the teacher-student relationship and learning within a community of practice. Implications for science teaching and learning in primary school community of practice settings are discussed.
