This article aims to describe the nature of emergent practice arising from conflicts student-teachers experienced in a teaching practicum and its implications for teacher learning. The authors used critical incident (CI) writing in ePortfolios as a means for student-teachers to record conflicts experienced and what was learned from them. The authors identified new teaching principles students developed through this experience. Furthermore, the authors also identified techniques and strategies they felt helped them teach effectively at their schools. Lastly, the critical incident also gives a view into the teaching principles, strategies, and world-view which comprise student-teacher emergent practice. The authors also regard the issue of theory to practice.
