Within teacher education problem-based learning (PBL) has the potential to enrich teaching and learning across the curriculum. It is suggested that PBL may offer a means of providing authentic scenarios for assisting pre-service teachers before encountering teaching practice. The use of media-based educational triggers and authentic scenarios may form a bridge between their studies and real-world teaching practice. Five media-rich educational triggers are described in early childhood education, physical education, educational technology, project management and inclusive education. Reusable media-based educational triggers may also provide potential resources for other educators within teacher education.
