生物新课程标准倡导探究性学习,要求教师引导学生主动参与探究过程。只有学生的主体作用得到发挥,生物课堂教学才能突破以教师传授知识为主要特征的相对封闭的传统教学模式;学生主体地位得到落实,学生才会有主动发展的机会。因此,在高中生物课堂教学中实施主体性教学,充分发挥学生的主体作用,调动学生积极主动地参与生物教学活动具有重要的现实意义。一、确定三位一体的教学目标课堂教学不仅传授给学生知识,而且也对学生 Biology new curriculum standards promote inquiry learning, requiring teachers to guide students to take the initiative to participate in the inquiry process. Only when the student’s main role has been brought into play can the biological classroom teaching break through the relatively closed traditional teaching mode characterized by the teacher’s imparting knowledge. Only by implementing the student’s subjective status can the students have the opportunity to take the initiative to develop. Therefore, it is of great practical significance to carry out subjective teaching in the teaching of biology in senior high schools, give full play to the main role of students, and mobilize students to actively participate in biological teaching activities. First, determine the trinity of teaching objectives Classroom teaching not only imparted to students knowledge, but also for students
