| Cultivating talents with core literacy is the refinement and concretization of our party’s education policy,and also the objective requirement for implementing the fundamental task of“cultivating people with morality”.The “General High School Chemistry Curriculum Standards(2017 Edition 2020 Revision)” clearly points out the necessary core literacy and level requirements of high school students.Cultivating the core literacy of chemistry discipline helps students form correct values,essential characters and key abilities on the basis of understanding subject knowledge.The core literacy of chemistry is manifested in the activities of solving chemical problems,and experimental teaching is one of the most distinctive activities of this discipline,which has irreplaceable functions and values.Traditional chemistry experiment teaching is rarely based on the perspective of cultivating discipline core literacy.Therefore,it is of great significance to fully explore the function of chemical experiment teaching based on the goal of cultivating the core literacy of the subject.This paper takes the experimental content in the compulsory textbooks of senior high school chemistry as the carrier,fully excavates the core literacy teaching function of the experiment,and explores the effective teaching strategies to realize the core literacy teaching function in the process of chemical experiment teaching,aiming at achieving the goal of comprehensive education.The main research contents of this paper are as follows:First of all,by consulting the literatures to understand the research status of chemical experiment teaching function,the experimental content of high school chemistry compulsory course is systematically sorted out.Based on the five core literacy perspectives of “macro identification and micro analysis”,“changing ideas and balanced thinking”,“evidence reasoning and model cognition”,“scientific inquiry and innovation consciousness”,and“scientific attitude and social responsibility”,the teaching functions of five kinds of chemical experiments in textbooks have been explored in this paper.Secondly,the questionnaire survey method and interview method are used to conduct an in-depth investigation on the implementation of the core literacy teaching function in ordinary high school chemistry experiment teaching.Finally,based on the survey results,many teaching strategies in combination with specific cases have been also put forward.The teaching practice research is carried out by taking the first volume of the compulsory textbook of Jiangsu Education Edition “Prepare a Solution of a Certain Amount of Substance Concentration”,“Properties of Concentrated Sulfuric Acid” and “Testing of Sulfate Ions” as examples,and the teaching effect is tested by after-school test questions to verify the feasibility and effectiveness of the teaching strategy.Through the research on the function of chemical experiment teaching from the perspective of core literacy,the research conclusions were obtained:(1)In the teaching of high school chemistry experiment,the teaching function of chemical experiment was innovatively excavated from the perspective of core literacy,and the corresponding teaching strategies were put forward,which significantly improved the effect of experimental teaching and comprehensive education.(2)The implementation of chemical experiment teaching that fully excavates the teaching function of core literacy will help students master subject knowledge in problem solving and promote the effective implementation of subject core literacy in the process of knowledge learning. |
