A Practical Research On The Application Of Chemical Popular Science Resources In High School Chemistry Teaching Under The Guidance Of Core Literacy

The development of science and technology has created a situation in which the knowledge of various disciplines intermingles with each other,and chemistry science resources,not only disseminate the basic knowledge of chemistry,but also involve many fields such as society,life,and environment.Their significance is not only to spread scientific knowledge,but also to broaden students’ horizons,develop their thinking and let them appreciate the connection between chemical knowledge and production,life and society.The rich and diverse chemistry science resources are an excellent educational resource.This study is guided by constructive learning theory,humanistic learning theory,and informal learning theory under the guidance of core literacy,and uses chemistry science resources to integrate them into teaching and learning to stimulate students’ interest in learning and promote the formation of students’ core literacy in chemistry.The purpose of this study is to understand the application and attitudes of high school chemistry teachers towards chemistry science resources in classroom teaching and the understanding,perceptions and attitudes of high school students towards chemistry science resources;secondly,to analyze the effects of applying science resources through watching science videos and designing and implementing teaching cases using chemistry resources;thirdly,to explore the ways of applying science resources through analyzing the effectiveness of applying science resources.In this regard,the author has conducted the following researches.First,a questionnaire was prepared for high school teachers and students to study teachers’ application and attitude toward chemistry science resources in classroom teaching,and high school students’ understanding,opinions and attitudes toward chemistry science resources through a questionnaire.Second,based on students’ basic and subject-based knowledge,we selected relevant science videos,organized students to watch them,and analyzed the impact of science videos on students’ learning by means of student interviews.Third,the teaching design of science application was designed,and a case practice study was conducted,divided into experimental and control classes,and the teaching effects were analyzed by means of post-class tests and interviews with listening teachers and students.The study showed that most teachers agreed that chemistry science resources could help improve classroom teaching,cultivate students’ love for chemistry,and increase their interest in learning,and they were also willing to use chemistry science resources to assist their teaching.The problems were that chemistry teachers paid little attention to chemistry science resources,did not understand them deeply,and lacked time and energy to select suitable chemistry science resources.Students’ acceptance and recognition of chemistry science resources are very high,and students are interested in their learning.The use of popular chemistry resources in chemistry teaching is conducive to improving classroom efficiency,stimulating students’ enthusiasm and interest in learning,helping students’ learning and understanding,promoting not only students’ academic performance,but also their love for chemistry,promoting the development of students’ core literacy,and contributing to students’ development.Therefore,teachers should act as a popular science worker in teaching,use chemistry science resources in classroom teaching,give full play to the beneficial effects of chemistry science resources,promote students’ overall development and improve their core literacy in chemistry.The means that can be used are: first,based on the knowledge of textbooks,second,to meet the interests and knowledge acceptance ability of students,third,combined with the historical facts of chemistry,and fourth,combined with life and social hot issues.
