  13. 13. CASE STUDY • 20 persons: 3 CGIAR, 2 Law, 8 CS teachers & 7 CS TA’s. • An online survey about usefulness, teacher issues and how the tool can resolve these. • on average: 40 mins are spent using SAM. 9Thursday 8 December 11
  14. 14. CGIAR CASE STUDY issue for teacher addressed Provide feedback to the students ✔ ? Being aware of what students are doing ✔ ✔ Knowing about collaboration and communication ✔ ✗ Knowing which documents are used and how much ✔ ✔ Knowing how and when online tools have been used ? ✔ Finding the students who are not doing well ✔ ? Finding the best students ? ? Knowing how much time students spent ? ✔ Knowing if external learning resources are used ✔ ? 10Thursday 8 December 11
