传统的化学教学是单向灌输式的教学，忽视了学生的认识活动，学生处于被动接收的地位，学完全受制于教。教师教得越多，反而给学生获取知识、独立思考和行动提供的机会越少，形成了“化学小八股”：教师—押题—教得分方法—讲类比习题学生—猜题—做模拟题—练公式化步骤... Traditional chemistry teaching is one-way indoctrination teaching, ignoring the student’s cognitive activities, students are in a passive receiving position, and learning is completely subject to teaching. The more teachers teach, the fewer opportunities for students to gain knowledge, independent thinking and action, and the less chance they have for the formation of “chemical babolets”: teacher-chart-teaching method-speaking analogy student-guessing question-doing a mock question — Practice Formulation Steps...
