This video is a presentation about transformative teacher development activities. The presenter (Gerardo Valazza) starts by defining CPD (Continuous Professional Development) and discusses different ways to engage in CPD, such as reading articles, attending conferences, and observing other teachers. He then delves into the concept of effective CPD, drawing on the work of Silvana Richardson and Gabriel Diaz Maglio. Gerardo introduces the acronym INSPIRE, which stands for Impactful, Needs-based, Sustained, Collaborative, In-practice, Reflective, and Evaluative. Gerardo explains each letter of the acronym and provides questions to help teachers reflect on their own CPD practices. The overall message is that effective CPD should be focused on improving student learning and should involve a combination of learning, reflection, and action.
