新课程改革强调倡导学生通过“自主、合作、探究式”学习,利用“问题导学法”进行教学活动,学生的学习目标性、针对性、主动性更加强。基于问题而学习,自主学习不是漫无目的,而是在生物教师的引导下,围绕着有价值的问题,寻找解决问题的线索,展开思考、讨论、学习、探索,提高学生学习的兴趣,使课堂教学更有效、更高效。教师在教学过程中有意识地创设情境,引导为学生提问;通过解决学生在课堂上生成的问题,吸引学生注意力;通过研读教材,利用其设计的问题难易梯度,合理提问。
The new curriculum reform emphasizes advocating students through “independent, cooperative, exploratory ” learning, the use of “teaching method ” teaching activities, student learning objectives, targeted, more initiative. Based on the problem of learning, autonomous learning is not aimless, but under the guidance of biological teachers, around the valuable problems, find clues to solve the problem, to think, discuss, learn, explore, improve students’ interest in learning so that Classroom teaching is more effective and efficient. Teachers consciously create situations during the teaching process, guide questions for students, attract students’ attention by solving the problems generated by students in the classroom, and make use of the difficulty of gradients and questions as they are designed through reading teaching materials.
