传统课程中的教师是课堂教学的中心,这决定了学生在课堂中的地位是被动的、消极的。教师仅仅把学生当作装知识的“容器”,过于强调接受学习、死记硬背、机械训练,遏制了学生的创造性思维能力。在化学教学中应有意识地不失时机地给学生提供创新的环境,使他们敢于创新、乐于创新 Teachers in traditional courses are the center of classroom teaching, which determines that students’ position in the classroom is passive and negative. Teachers only regard the students as “containers” of knowledge, which emphasize acceptance of learning, rote learning, mechanical training, and curb students’ creative thinking ability. In chemistry teaching, we should consciously lose no time to provide students with an innovative environment so that they dare to innovate and be willing to innovate.
