Why Open-book Tests Deserve a Place in Your Courses. With the proliferation of learning management systems (LMS), many instructors now incorporate web-based technologies into their courses. While posting slides and readings online are common practices, the LMS can also be leveraged for testing. Purely online courses typically employ some form of web-based testing tool, but they are also useful for hybrid and face-to-face (F2F) offerings. Some instructors, however, are reluctant to embrace online testing. Their concerns can be wide ranging, but chief among them is cheating. Instead of wasting valuable time to deter cheating, open-book tests shift the onus of responsibility onto the students themselves. They are the ones who must track down answers and page through online notes.
