This is the third Foundation session. This session probes deeper into how learning happens. The focus is on how learners construct an understanding of the world around them through experiences, social interactions, and making connections with their prior knowledge. Participants do an activity that offers them a shared experience upon which to reflect on the role of prior knowledge, social interactions and the use of models in their personal experience as a learner, by doing an activity that places them in the role of the learner. Participants consider the four foundational ideas on learning, and discuss the implications of the research on how to support learning as they present and design their activities.
