Abstract In order to improve the teaching effect, a new teaching mode based on smart phone-wireless screencast-projector has been well designed. These teaching units such as experimental principle, experimental instrument operation, correction of common error in experimental operation and safety training have been performed with high efficiency. This new teaching mode breaks through the limitations of lab space, which not only helps teacher instruct students with high efficiency, but also makes students do chemical experiments with good scientific habits and further increase their experiment grades.
