The difference between lecture and trial lecture: lecture is a kind of pre-class behavior, which is the teaching assumption and theoretical basis for teachers to express topics orally, that is, teachers tell their own teaching design on the basis of preparing lessons, and it is a relatively independent teaching organization form after preparing lessons and before teaching. It is an explanation of the design of classroom teaching scheme, not only what to teach, how to teach, but also why to teach so, emphasizing depth. Trial lecture is a simulation of conventional teaching, which requires candidates to fully demonstrate their classroom teaching skills in a specific situation and within a limited time. In short, the lecture is about teaching design and its analysis, and the trial lecture is the concrete implementation of teaching design and its analysis.
