Junior High School Biology Classroom Use "practice First Then Teach" Model Research Of Cultivating Students’ Autonomous Learning Ability

The 21 st century is the era of fierce international competition, and the focus of competition is the talent competition,in the era of the rapid development of the knowledge, the knowledge update speed, cycle is short, information explosion, knowledge explosion.whether in this society full of competition for Junior high school students have the ability to adapt and competition ability, is whether the students have the ability of Autonomous learning.So school education take training students’ autonomous, cooperative learning mode, which can help students to better adapt to the nowadays,but it requires teachers to teach students how to learn, how to better grasp the knowledge.This gives the majority of the first line teachers to cultivate students’ independent learning, independent thinking, willing to explore, innovation ability of the new teaching goals and tasks.In this study through the Junior high school biology classroom teaching use "practice first then teach" teaching mode to cultivate students’ autonomous learning ability. "Practice first then teach" teaching model refers to teachers in the teaching process can not be simply to impart knowledge,and use all kinds of teaching methods, arouse students’ learning interest, form a kind of teaching mode of autonomous learning.This research focuses on "practice first then teach" teaching mode of teaching design in practice implementation and modification process.In this paper adopts, literature survey,case analysis combined with the questionnaire survey to Urumqi City, the fifth Junior high school in seventh grade class 4 students as the research object, before using "practice first then teach" teaching mode and students’ academic achievement and student learning of biological interest and motivation, students autonomous ability questionnaire scores as evaluation standard, fair evaluation of students’ autonomous learning ability, And the data were analyzed. The results of the study show that "practice first then teach" teaching model applied to teaching practice effect is obvious, the students’ interest and motivation has been significantly improved, think after studying biology very happy the number of percentage pretest 3.7%, Post test 37%, prefer to read extracurricular books about the biology of the number of percentage pretest 4%, Post test 49%;Students are basically formed a good learning habits, according to data statistics more than 50% of the students to be able to preview before class, after review and problem solving for reflection.The classroom efficiency is improved obviously,Actively to the teacher ask questions in class the number of students increased from 35% rose to 48.9%, they would actively doing exercises of write the number of students from 31.5% rose to 57.4%,The number of students willing to write questions actively from 31.5% rose to57.4% have learned the knowledge induction, summary of the number of students has increased significantly,The students’ academic performance is also improved obviously;use of "After the first practice teach" teaching model students before exam the average score of 58.9 points, the average score of the final exam students use after 71.2 points, there is clear difference.In biology class by design scenarios, exercises,guiding case etc. Guidance introduction of new courses, help to stimulate students ’interest and motivation to improve students’ Autonomous ability.In biology classroom teaching of "practice first then teach" teaching mode finally achieved the goal of training students Autonomous ability, achieve the goal of the new curriculum requirements.
