Abstract: Techniques are disclosed for teaching and learning about the substance of law, the doctrine of law, and the substance of lawyering skills. The same techniques may be applied to fields other than law. Information related to a course is provided to one or more students in an electronic form, such as on a CD/DVD or over a network connection. Such information may, for example, be related to a practicum exercise (such as a mock trial) and include a variety of information related to that exercise, including source materials and links to commentary by faculty members. The course also includes Faculty Supervised Tutorial Studies (FSTS), which are based on interaction between students and faculty throughout the course. Testing and/or assessment may be performed during the FSTS and/or at the conclusion of the FSTS. The testing/assessment may be conducted, for example, online through a written analysis or through a series of questions.
