Practical Research On The "235" Teaching Mode Based On KWL Strategy In The Seventh Grade Biology Teaching

An important specific requirement of educational reform is that teachers should optimize teaching methods and advocate heuristic,inquiry and cooperative teaching.The KWL strategy studied in this paper is a metacognitive process based on students’ learning,which guides and records the learning process with three steps,namely,K（what I know）,W（what I want to know）and L（what I have learned）,so as to cultivate students’ learning ability.The "235" teaching mode refers to the teaching mode in which students’ learning is the mainstay,supplemented by teachers’ guidance,and the teaching tasks are completed through the teaching links of preview,cooperation,exploration,demonstration and practice,etc.in three teaching time distributions.In this paper,KWL strategy is effectively combined with "235" teaching mode,and the teaching design is based on "235" teaching mode of KWL strategy,so as to enhance students’ learning interest,cultivate and improve students’ autonomous learning ability and cooperative learning ability,and meet the requirements of education and teaching reform and development.This paper firstly analyzes the research status and theoretical research basis of KWL strategy and "235" teaching mode through the literature method,combined with the characteristics of junior high school biology classroom teaching,designs and constructs a student-centered,teacher-led,teaching effectiveness and reflective teaching model.The basic principle is the "235" teaching mode based on the KWL strategy,which is in line with the characteristics of junior high school biology and the characteristics of junior high school students’ physical and mental development.Secondly,two parallel classes in the practice middle school are selected as the research objects,and the KWL-based "235" teaching mode and the traditional teaching mode are used for practical teaching.Finally,the teaching effect is tested by means of questionnaires,interviews and the analysis of students’ biological performance.After four months of practical research,the students’ biological scores,questionnaire survey results and interview content were analyzed,and the conclusions were drawn: 1.The "235" teaching model based on the KWL strategy has an impact on students’ biological learning interest,autonomous learning ability,and cooperative learning ability.and so on has a significant improvement effect.2.The practical application of "235" teaching mode based on KWL strategy has been summarized.Third,put forward teaching suggestions for teachers who use the "235" teaching mode based on KWL strategy.Front-line teachers and scholars can take this as the direction of teaching innovation and future research to promote the progress and development of subject teaching.
