Thinking about formative assessment as conceptual building blocks and lever for promoting peer interaction
Sarah and team - that's a solid blueprint. I'm impressed and reading this inspires me to want to register for the course.
The nature and structure of the course lends itself well to incorporating structured e-Activities as building blocks your summative assessment. These could take the form of blog posts / reflective journal like activities covering discrete steps leading up to the preparation of the summative assessment items (eg the issues paper). These e-activities are a good way to generate peer learning support for the OERu learners.
