Research On The Cross Teaching Of Biology And Chemistry In High School Under The Concept Of Core Literacy

With the continuous development of the science and technology society,the demand for comprehensive talents is higher and higher.At present,the teaching of middle school in our country is still based on the sub-disciplinary curriculum,although it can let the students acquire the knowledge within the subject,it is also artificial to separate the links between the subjects,which is not conducive to the overall development of the students.In the course reform of basic education,which started in 2001,it is pointed out that it is necessary to dilute the boundary between subjects and strengthen the connection between subjects,it can be seen that interdisciplinary teaching plays an important role in promoting the all-round development of students.With the implementation of the new college entrance examination policy,the students who choose biology in the selected subjects are far more than those who choose chemistry,but biology and chemistry are inseparable,in order for students to better understand and master knowledge,it is necessary to make appropriate interdisciplinary for the intersection points related to chemistry in biology.The new curriculum standard 2017 points out that strengthening horizontal links between disciplines can help students understand the nature of science,ideas and methods,interdisciplinary scientific concepts and processes,which is helpful to develop students' core literacy.Therefore,it is of positive significance to cross-teaching of biology and chemistry in high school under the concept of core literacy.This study mainly includes the following parts.The first part is an introduction,which mainly discusses the research background,purpose and significance,present situation,content and methods,and defines relevant concepts and puts forward the innovations.The second part is the theoretical basis of interdisciplinary teaching under core literacy.The third part is to investigate the current situation of cross-teaching of biology and chemistry in senior high school under the concept of core literacy,it is found that most teachers are no stranger to cross-teaching of subjects at present,and they also affirm its necessity and significance,however,it is not highly used because there are no related teaching cases,finally,some suggestions for implementing interdisciplinary teaching based on core literacy were also putforward.The fourth part is based on the results of the questionnaire survey and the four dimensions of core literacy,taking the human education version as an example to sort out the intersection of biology and chemistry in high school.The results show that there are 66 intersections related to core literacy,and the abundant intersections illustrate the necessity of interdisciplinary in biology teaching in high school.The fifth part is to select typical intersections for proper case analysis under the core literacy concept,and propose the discipline cross-teaching general pattern.Finally,the case is applied to teaching practice and tested through paper and pencil tests and interviews,the results show that interdisciplinary teaching can help students better understand and master knowledge to a certain extent;interdisciplinary teaching is conducive to improving students' comprehensive ability and developing students' core literacy.This study aims to provide suggestions and references for first-line biology teachers to carry out interdisciplinary teaching based on core literacy.
