PowerPoint is now widely used in lectures to science students in most colleges of China. We summarize its advantages as producing better visual effects, high efficiency in information transfer, precise and systemic knowledge structure. Disadvantages of PowerPoint may be induced by irrelevant information in slides, neglect of interaction with students, uncontrolled speed in presenting or too strict order of slides. Strategies to avoid these disadvantages are proposed.

Blackboard platform is currently used for undergraduate education in our college. To investigate its role in physiology learning, we conducted a survey on undergraduate students in nurse major. The results suggested that Blackboard platform is helpful and playing an important role in physiology learning. But compared with other learning manners, e-learning on Blackboard is neither the mostly adopted method of learning, nor the preferred means in reviewing. We conclude that Blackboard is not a substitute of textbook, but Blackboard learning may become an important complement to traditional education in undergraduate students.
