Teacher learning is essential to the teaching profession, because it has been strongly linked to improved teaching practices and teacher quality. The source for teacher learning is initial teacher education, a crucial phase in the learning-to-teach continuum. To gain insight into this influential period for student teachers' long-term professional lives, this exploratory study investigates student teachers' participation in learning activities and explores whether it is connected to their own effective teaching behaviours in a school-based teacher education setting for secondary education in the Netherlands. The results indicate that student teachers vary in their self-reported learning and that this learning relates positively to observations of their effective teaching behaviour. These findings have several implications for teacher education programmes that aim to enhance the likelihood that their student teachers will become career-long learning professionals.
