优化课堂结构 构建优质、高效的[小组自主互助合作]　教学模式－让学生动起来，课堂活起来，效率高起来

培养学生的创新精神和创新能力。让学生成为课堂的主人，把课堂时间还给学生。让学生充分的合作、交流、探究、评价，让学生自己提出问题，解决问题。充分尊重学生的潜能和主体地位，把大量的课堂时间留给学生，使他们有机会进行相互切磋，共同提高。提倡[教师当好导演，学生当好演员]，不能把学生当成[听众]。创造一种民主、和谐的教学氛围，从而达到优化课堂教学，提高课堂效率的效果。

Cultivate the students' pioneering spirit and compentence. Let the students be the owners of the class and return classes and time to them. Let the students cooperate， communicate， probe and evaluate completely. Let the students find and solve problems by themselves. Fully respect the students' latent energe and main status. Leave the main class time to the students so as to make them have the chance to discuss with each other and make progress together. We advocate ＂Teachers should be good directors and students should be good actors.＂ Don't regard the students as ＂audience＂. We should create a democratic and harmonious teaching atmosphere to get the result of bettering the classroom instruction and heightening the class efficiency.
