The Construction and Application of a Teaching System of Hand-held Technology Digital Chemical Experiments Containing "One Research, Two Websites, Three Laboratories, Four Models, and Multiple Practical Platforms"

The requirements for the training of chemistry students in normal universities are gradually hightened with the progress of the new curriculum reform. In order to solve the problem of "how to establish a teaching system for hand-held technology digital chemical experiments" in experimental teaching in normal universities and to promote the cultivation of innovative talents in the 21st century, the "seven types of knowledge and seven types of ability" chemistry teacher training framework was formulated and a teaching system of handheld technology digital chemical experiments containing "one research, two websites, three laboratories, four models, and multiple practical platforms" was created on the basis of the research and practice of undergraduates' knowledge and ability training in normal universities. The research can play a guiding and exemplary role in the training of preservice teachers for higher education.
