Case Analysis And Research Of High School Biology "same Class And Heterogeneous"

With the deepening of the curriculum reform of basic education,the task of creating a person by virtue will be put into the school curriculum,and higher requirements will be put forward to the front-line teachers.Teachers need to improve their professional qualities to meet the requirements of the new curriculum reform."lesson with heterogeneous" is widely used in the research of basic education practice teaching,the same teaching content is presented by different teachers,which is more comparative,and it is easier to get the research results.This paper mainly selects the case of "lesson with heterogeneous" from the daily classroom of biology in the first year of senior high school,and through the case analysis of the four kinds of "lesson with heterogeneous" of the new teaching,the experimental class,the review class and the exercise lesson.The strategies to improve the effectiveness of four kinds of classroom teaching are put forward,and the overall strategies to enhance the effectiveness of classroom teaching in biology are summarized.This paper is divided into six parts:The first part describes the background,research significance,research methods and research process.The second part defines the relevant concepts and "lesson with heterogeneous" related literature review,including the isomerism of the same class,case analysis and classroom teaching effectiveness of the concept of definition,and the same class of heterogeneous types and domestic and foreign research status quo is briefly summarized.The third part analyzes the teaching cases of "lesson with heterogeneous" in the four classes of biology in senior high school.The fourth part aiming at the problems existing in teaching cases,and the teaching phenomena observed in the "lesson with heterogeneous",the author puts forward the strategies to improve the effectiveness of biology classroom teaching in senior high school.The fifth part summarizes the overall strategies to improve the effectiveness of high school biology classroom teaching.The sixth part reflects on the deficiency of this paper.
