This article describes the development of a portfolio process based upon digital photographs taken to document the first teaching practicum of student teachers. This portfolio process was implemented solely for the purpose of enhancing learning through professional reflection. The authors argue that one of the strengths of portfolios is the potential for the inclusion of authentic evidence. However, viewed from this perspective the original portfolio process did not appear to be achieving the intended high level of authenticity. Furthermore, the portfolio process intended to promote self-reflection and the self-awareness that arose from genuine reflection. However, students’ selection justifications frequently appeared to be based upon the external judgement and feedback comments made by academic staff.
