Research On Effective Teaching Strategies Of High School Biology Units Under The Background Of New Curriculum Refor

Under the background of the new curriculum reform,"deepening educational reform and promoting quality education" proposed by the State Council,requiring changing the previous learning form that required students to memorize by rote and do a lot of brushing questions to improve their grades,and cultivating socialist builders and successors with all-round development of morality,intelligence,physique,aesthetics and labor on the basis of reducing students’ burden.Effective teaching suits the times need,which the maximum teaching outcomes are obtained with the minimum energy consumption.Selection and optimization is the key to effective teaching.Focused on the "inefficient" phenomenon of high school biology unit teaching,This paper combined with the research results of current effective teaching strategies and effective biology teaching theory.Under the background of the new curriculum reform,the main purpose is to improve the "effectiveness of biological learning" for high school students;Combined with the status of high school biology unit teaching in Hechuan Middle School,It is discussed that the strategies to improve the effective teaching of high school biology unit,which is helpful to complete the expected teaching goals and promote the all-round development of students.The author defines the concept of effective teaching of high school biology units through literature review,and obtains the characteristics of effective teaching of high school biology units by combing through domestic and foreign research results and empirical research during internship.According to the characterization,it is constructed that an effective teaching index system of high school biology.A questionnaire made according to the system;Through questionnaire surveys of students and interviews with teachers,we can knew the current situation of effective biology teaching in high schools.Combined with the analysis of classroom teaching action research,It was explored that the main crux of the effective existence of high school biology.From the pre-class preparation,in-class implementation and post-class evaluation,the author proposes effective teaching strategies for high school biology units: effective teaching preparation for high school biology units: knowledge-systematic arrangement strategy,motivation-continuity maintenance strategy,purpose core-literacy integration strategy;In terms of effective teaching of high school biology units and implementation: scene-creation strategy,problem string strategy,group cooperative strategy and so on;Evaluation of effective teaching of high school biology units: evaluation of overall design,evaluation of relevance planning.According to the construction strategy,the author carried out the teaching design and practice of "The Nature of Genes" in the high school biology compulsory course II "Genetics and Evolution" of the People’s Education Edition,and analyzed the application effect.The analysis shows that the effective teaching strategies of high school biology units can play a certain role in improving teaching effectiveness and students’ thinking ability.
