In high school biology teaching, we piloted the discussion-based teaching, the specific approach is divided into four steps. The following is an introduction of the teaching of “Reproductive Biology of Biology” in the first section of Chapter Three as follows: (1) Arrangement of Pre-syllabus An outline of the pre-syllabus is an important means of cultivating students’ self-learning abilities and ability to analyze and solve problems. The outline is as follows: 1. What is asexual reproduction? What kinds of asexual reproduction? What is the difference? What is the practical significance of grafting? 2. What is sexual reproduction?
