Sampling Investigation And Analysis On The Low Efficiency Of Biological Experiment Teaching In Grade 7 In Tianjin

Biology is a natural science based on experiment.Biological experiment plays a vital role in biology teaching.It is not only an important part of biology teaching,but also an effective teaching method in biology teaching.Since 2001,with the advancement of the new curriculum reform of basic education,new requirements have been put forward for junior high school biology experiment teaching.However,in recent years,inefficient teaching has been plagued junior high school biology experiment teaching,which is not conducive to the progress and development of students,but also seriously affects the implementation of junior high school biology experiment teaching objectives in the new curriculum reform.Based on this,it is urgent to study the effectiveness of junior high school biology experiment teaching and effective teaching strategies related to biology experiment teaching.This research combines the effective teaching theory with the“new requirements”of junior high school biology experiment under the background of the new curriculum reform.It starts with the attitude of junior high school students towards biology experiment class,some learning behavior of students before,during and after the experiment class,and the discipline performance of the experiment class.By using the method of questionnaire survey,the teaching of biology experiment class in grade seven can not be achieved.The new curriculum standard requires that the specific factors of inefficient teaching be investigated and studied.Combining with the statistical results of questionnaire survey data,this paper analyses the reasons leading to inefficient teaching of biology experiment.On the basis of consulting relevant literature,combining with my practical teaching experience and understanding,and it puts forward corresponding teaching strategies exploratorily,In addition,the study also provides relevant case analysis,close to the actual experimental teaching,which can provide valuable reference for the vast number of front-line teachers in the actual experimental teaching.
