The class lead-in is like music "gateway", drama "prelude", which can apply colours to a drawing atmosphere, focus into the situation,stimulate interest in learning.Because of the current students’ interest in learning biology curriculum is not high,the class lead-in in high school biology teaching process has not been enough attention.Besides the study of high school biology classroom import relatively lack.So it is necessary for specific materials to explore practical and guide significance to the class lead-in, enhance students’ interest in learning biologyand improve the quality of teaching.Based on the Rogers’ s humanism learning theory, theory of the zone of proximal development and Piaget’s constructivist learning theory,the paper summarizes and expounds the function, principle, classification of the current biology classroom import,through consulting a large number of literature.This paper collects the import case 66 for the steady state and the environment of high school biology of people’s education,in xinyuan county second middle school students as the research object.In the effective classroom before and after the import case,through the study of distributed object "about students learning interest and learning attitude questionnaire survey found that experimental classes students compared with that in comparative classes of learning interest and learning attitude had obvious increase.The experimental class student’s result has increased significantly by Choosing some students to interview,which found that after class the students got more easy to master new knowledge, through experimental classes in comparative classes.In conclusion, this study about three the steady state and the environment of compulsory module import case has optimized in each chapter, provided systematic classroom import case, for the high school biology teachers has certain reference significance.The effective classroom import can make students do the subjective initiative of biological learning better, better achieve biological teaching, help the biological teaching to improve the effect of classroom teaching and significantly improve student performance.But this study also had some limitations,such as the object scope of too small, lack of representative;limited byI teaching practice time,studiedonly one semester practice effect and some chapters import case is not ideal enough. |
