The Applied Research Of Physical Model Construction In The Module Teaching Of Molecule And Cell

At present,the "curriculum standards" at home and abroad all require students to have modeling ability,and "model" has become an important part of the talent selection test.Through literature review,it is found that the existing biophysical model of high school is fragmented and not systematic,so it is particularly important to carry out the applied research on the teaching of physical model construction.This paper takes the compulsory 1 module of high school biology in people's education edition as the research material,and carries out the application research of physical model construction in high school biology teaching from three aspects.Firstly,the paper reviews the current situation of the model construction in biology teaching by literature analysis and defines the relevant concepts.Second,it summarizes the content of physical model construction in compulsory 1 textbook,and expounds the specific application of physical model construction in teaching from five aspects:modeling reasons,material preparation,knowledge preparation,modeling guidance and model application.Thirdly,a one-month practical study was carried out in a middle school in nanchang city.The changes of the experimental group and the control group before and after the education experiment were compared through classroom observation,questionnaire survey,test and interview,and the practical research results were obtained.Preliminary results show that:Physical model construction teaching can significantly improve students' interest in biology learning.It can improve students' performance to a certain extent,and the better the result is with the teaching,but it still cannot achieve significant improvement in a short time.In addition,physical model construction teaching can improve students' ability of cooperation,communication and modeling.
