一、创设问题情境,提出合理有价值的问题思维来源于疑惑,对某一问题的思索是激起学习欲望,激励创新精神的积极因素。因而在教学过程中教师要深入研究教材,围绕教学目标精心设疑,精心设置障碍,突破教学重点难点,设计一个由浅入深,层层推进的进程,使学生的思维从表象到本质向纵深 First, create problem situations, and propose reasonable and valuable problem thinking originating from doubts. Thinking about a certain issue is a positive factor that stimulates learning desire and encourages innovation. Therefore, during the teaching process, teachers should study teaching materials in depth, carefully question the teaching objectives, carefully set obstacles, break through the key teaching difficulties, and design a process that progresses from shallow to deep, and pushes the students’ thinking deeper from appearance to essence.
