At the OU we create online/digital resources in various formats for our students, and expect them to be digital natives who can use them effectively, but what evidence do we have that this is the case? This session reports on research carried out to look at how students actually study. Students on three STEM second year modules who have study materials supplied in different formats (from entirely online to mostly book based) were surveyed, and in-depth interviews carried out. The results contained a few surprises which may influence how you design your course material going forward. Come and hear more about our findings.
