课堂的主体参与者是教师和学生,课堂是否高效最终还是这两个因素在起决定性作用。学生学习生物的主动性、积极性、需要教师去调动、培养和引导。如果师生双方都行动起来,沉闷的、令人憋屈的生物课堂气氛定会以充满活力、充满快乐的课堂氛围而取代。因此,构建初中生物高效课堂,我认为必须牢记两个“重视”。一、重视教师自身的专业的发展1.用娴熟的专业知识去准备每一节课,争取获得高 The main participants in the classroom are teachers and students. Whether the classroom is efficient or not will ultimately play a decisive role in these two factors. Students learn biology initiative, enthusiasm, teachers need to mobilize, train and guide. If both teachers and students act, the dull, obsessive biology class atmosphere is set to be replaced by a vibrant, joyful classroom atmosphere. Therefore, to construct a junior high school biology efficient classroom, I think we must keep in mind two “emphasis ”. First, attach importance to the development of their own professional teachers 1 with the expertise to prepare each lesson, strive for high
