The document discusses using email and case studies as e-learning tools. Email allows for communication, sharing of attachments and activities, and monitoring of learner interaction. Case studies can incorporate multimedia to tell engaging stories and prompt research from different perspectives. Both tools support visual and verbal as well as active and reflective learners when used for collaboration, such as assigning group emails or activities to develop solutions. The trainer's role is to engage students, provide feedback, and support learners through online discussion or email while assessing learning through exams or papers.
