Teaching Practice And Research Of Constructing High School Biology Efficient Classroom Based On KWL Model

Under the background of new high school curriculum standards and education and teaching reforms,higher requirements have been placed on the quality and efficiency of high school biology classrooms.Many researchers have applied new teaching methods and teaching models to high school biology classrooms to make good use of the classrooms.Time to efficiently achieve teaching goals,advocate students as the main body of the classroom,strengthen exchanges and cooperation between teachers and students,and cultivate students with all-round development.The KWL(Know,Want to know,Learned)mode of teaching is a learning strategy based on schema theory.On the basis of existing cognition,students can actively acquire new knowledge through autonomous learning,which can reduce teachers’ teaching in the classroom.time and improve classroom efficiency.This paper will take this as the starting point and use the KWL model to construct an efficient high school biology classroom,which can not only promote the development of KWL teaching in curriculum learning,but also provide certain benefits for front-line teachers in high school biology using the KWL teaching model to build an efficient classroom.This study uses the literature review method to define the related concepts of KWL teaching and efficient classroom,and expounds and analyzes the research status of KWL teaching and efficient classroom at home and abroad.Design the implementation plan of applying the KWL model to the high school biology classroom,and apply the KWL model to the high school biology classroom through the experimental research method to carry out teaching practice research.Two classes of students whose situation is basically the same as the research object,through the KWL teaching practice,analyze the pre-and post-test scores of the students in the two classes and the results of the interviews with teachers and students,the main research results and conclusions are as follows(1)Based on the KWL model teaching construction The high-efficiency biology classroom in high school is feasible,and the three-link teaching of the KWL model is the key factor in constructing an efficient classroom.(2)The use of KWL model teaching can improve students’ biological performance,and it has different effects on students at different levels of learning ability.Using SPSS software to analyze the scores of the two classes,there was no significant difference in the pre-test scores(P > 0.05),and the two post-test scores after the teaching practice showed that there was a significant difference between the experimental class and the control class(P < 0.05).,and from the scores of students in the experimental class,it can be concluded that KWL teaching has a more significant impact on the biological performance of students with low and middle levels.student biology.(3)Under the KWL model,students’ autonomous learning ability and questioning ability are improved,teachers and students interact more in class,and cooperative learning among students makes the classroom more active.Students become the main body of the classroom,the teaching effect is good,and the efficiency of biology classroom is improved.Finally,in view of the shortcomings of KWL teaching in this experimental study,the research and reflection on the subject research are carried out,and the KWL teaching suggestions are summarized,and the future research prospects are put forward.Efficient classrooms promote the development of middle school biology education.
