Research On Classroom Teaching Of Interdisciplinary Concepts In Chemistry Curriculum From The Perspective Of Core Literacy ——Taking "Energy And Matter" As An Example

Under the background of the new curriculum reform,our country pays great attention to the cultivation of students' core qualities at present.Discipline core literacy is the concentrated expression of the value of discipline education,and is the correct value,essential character and key ability that students gradually form through discipline learning.With the implementation of new course reform and the issuance of new course standards,our country pays more attention to the training of students' scientific ideas and the development of their comprehensive quality.By incorporating interdisciplinary concepts into chemistry classroom teaching,students can understand the core concepts of science from an interdisciplinary perspective,solve practical problems with interdisciplinary thinking,and develop core qualities.Therefore,integrating interdisciplinary concepts into the teaching of the course has higher theoretical and practical significance,can help students form a perfect structure of scientific knowledge,form rigorous scientific attitudes,and develop the view of scientific nature.In addition,this process is conducive to promoting the professional development of teachers,so that educational and teaching activities follow the pace of social development.In order to achieve the above purpose,this study takes the interdisciplinary concept "energy and material" as an example.First,the origin and research status of the interdisciplinary concepts at home and abroad are analyzed.Second,on the basis of comparing the curriculum standards of various disciplines in high schools in China with NGSS in the United States,the possibility of selecting the content of chemical disciplines for interdisciplinary teaching is analyzed and the teaching forms are integrated.The teaching content takes the carbon cycle in the ecosystem as the main line.Chapter 1,Section 2 of the compulsory requirement of chemical selectivity for high school students' Education Edition-"Calculation of reaction heat",carries out the teaching design of this section in the form of new teaching and carries out the teaching practice.Finally,in order to verify the effectiveness of the cross-disciplinary concept "energy and substance" in the teaching of chemistry in high school,the students' learning situation is evaluated in the form of pre-test and post-test.The pre-test and post-test exercises examine the students' mastery of the cross-disciplinary concept "energy and substance" from different perspectives.Based on the above theoretical and empirical studies,the relevant conclusions can be drawn: interdisciplinary teaching can enhance teachers' and students' interdisciplinary awareness,help students understand the nature of the core concepts of disciplines,improve the ability of interdisciplinary comprehensive problem solving,and develop students' comprehensive literacy.
