Study On The Current Situation Of Cross-penetration Teaching Of Biology And Chemistry In High School And Countermeasures

With the continuous promotion of basic education reform and the new college entrance examination model in many places,it makes for the comprehensive development of students receive more and more attention,and biology is a basic subject in natural science,which is the science of studying the phenomenon of life and the law of life activities,and is most closely connected with chemistry,which studies the composition,structure and properties of substances.Based on the characteristics of biology itself,cross-pollination with chemistry in high school biology teaching helps to cultivate students into well-rounded people.This thesis takes learning transfer theory,system theory,and multiple intelligence theory as the theoretical basis,and after defining the concepts of interdisciplinary and permeable teaching,and integrated curriculum,it organizes the intersection of knowledge between the compulsory part of high school biology and chemistry according to the order of biology textbooks and the requirements of curriculum standards,and argues the importance and feasibility of cross-permeable teaching between high school biology and chemistry.In addition,the author used student questionnaires and teacher interviews to understand the current teaching status of cross-penetration between biology and chemistry in high school.Through analysis,there are three main problems of high school biology teachers in teaching cross-penetration between biology and chemistry in the biology curriculum: 1.Teachers do not pay attention to the relevant content of cross-penetration between biology and chemistry;2.The educational value of cross-penetration with chemistry is not fully exploited;3.Teachers do not explore the cross-penetration The teaching methods are not explored enough.However,most students think that combining chemistry helps biology learning.In response to the problems reflected by the survey,the following strategies are proposed in combination with practice and teachers’ feedback: 1.Take the initiative to learn the relevant knowledge and form the awareness of subject crossover;2.Do a good analysis of the learning situation before class and pay attention to the progress of chemistry teaching;3.Create a platform for subject crossover and promote teachers’ cooperation and communication;4.Expand the channels of subject crossover and enhance students’ migration Awareness.The author combines the problems and countermeasures,carries out the teaching design of cross-penetration between high school biology and chemistry,and discusses and exchanges with first-line biology teachers to optimize the design.This paper presents the teaching design of cross-penetration between high school biology and chemistry in two sections of "Detecting Sugars,Fats and Proteins in Biological Tissues" and "ATP,the " Currency " of Energy in Cells" in Compulsory 1 of the PEP.
