2001年以“全面提高学生生物科学素养”为理念的生物课程标准正式颁布,“探究性学习”成为中学生物教学的重要理念和指导原则。随着新课标的进一步实施和贯彻,一些新问题也摆在了广大教师面前,比如课堂教学过程中学生提问较多而影响教学任务的完成,或者教师提问时课堂气氛不够活跃,课堂缺乏生机;教师艰辛的投入却换来学生考试成绩的不理想;实验课学生主动性差,应付了事等等。 In 2001, the standard of biology curriculum based on the idea of ​​“improving student’s biosciences in an all-round way” was officially promulgated. “Inquiry Learning” has become an important concept and guiding principle in biology teaching in middle schools. With the further implementation of the new curriculum standard and implementation, some new problems are also placed in front of the majority of teachers, such as classroom teaching process more questions and affect the completion of teaching tasks, or teacher questions classroom atmosphere is not active enough, the classroom lack of vitality; teacher Difficult inputs in return for the student test scores are not ideal; experimental students poor initiative, deal with things and so on.
