Using field-based assignments in math methods courses can help address the disconnect teacher candidates often experience between their prior math learning, developing understanding of learning theories, and clinical experiences. The document discusses how assignments like observations, interviews, and teaching help unify these experiences when supported by coursework. However, research shows methods courses may not be long enough to affect lasting change. Therefore, it is important to understand how field-based assignments specifically support teacher candidate learning and practice. The presentation aims to provide a rationale for these assignments, examples used, and their impact on developing teacher candidates' visions and skills in teaching mathematics.
