Does anyone else find that their students results in c2 and c4 are much lower than the other modules? Our results for the past few years have given 'U' shaped graphs for c2 and c4 ie the students can either 'do it' or not with very little in the middle, whereas the other modules give negative gradient graphs showing more can do it than not. What's going wrong with these 2 modules? This for my sins is my one of my performance management targets, to analyse, report back and hopefully improve results for these 2 modules. Any help/advise welcome!
