Research On Teaching Strategies Of Senior Middle School Chemistry Experiment Guided By Subject Core Literacy

Lide to cultivate people is the fundamental task of education.For whom to train people,who to train for,and how to train people are the fundamental issues of education.Chemistry,as an experiment-based discipline,has its own unique role in Lide Shuren's career.Its key role is to cultivate students' core literacy,that is,to cultivate students' "macro-recognition and micro-analysis" and "change".Concept and balance thinking","evidence reasoning and model cognition","scientific inquiry and innovation awareness","scientific attitude and social responsibility" and other five disciplines.Experimental teaching is an important part of cultivating the core literacy of students' chemistry subject,and it should be the focus of high school chemistry curriculum teaching.Due to many reasons,the high school chemistry experiment teaching in some places and schools has been weakened.The main reason is that the strategy of high school chemistry experiment teaching is not deep and systematic,and the experimental teaching methods are relatively outdated.For a long time,there have been many researches on high school chemistry experiment teaching,but there are relatively few researches on high school chemistry experiment teaching strategies based on the core literacy of the subject,so it is necessary to carry out practical research on it.This subject is oriented to the core literacy goals of the chemistry subject,using questionnaire surveys,interviews,quasi-experimental research and other methods to conduct practical research on the strategies of high school chemistry experiment teaching.Firstly,it explains the research background and significance of the subject,analyzes the status quo of research on high school chemistry experiment teaching strategies at home and abroad through the literature research method,and introduces the research content and methods of the thesis;secondly,defines related concepts and theories And the overview,laying a theoretical foundation for the subject research;again,using questionnaire surveys and interviews with three middle schools in D city as the research object,to investigate and research the current situation of high school chemistry experiment teaching under the subject core literacy orientation of the case subjects,and analyze the high school in D city The main problems in chemistry experiment teaching are: the choice of experimental problems is less related to production and life,and the lack of innovation in the design of experimental schemes,the choice of experimental reagents,and the choice of experimental instruments.Exploring the roots of the problems in high school chemistry experiment teaching from two levels of objective and subjective factors;finally,combining with the actual situation of high school chemistry experiment teaching in D city,from cultivating chemistry learning interest,expanding the content of chemistry experiments,focusing on chemistry experiment innovation,and guiding students to become independent Explore the cooperative learning and other aspects,and put forward the teaching strategy of high school chemistry experiment guided by the core literacy of the subject.According to the high school chemistry experiment teaching strategy guided by the core literacy of this subject,taking the properties of iron and ferrous salts in the People's Education Edition "Chemistry 1" and the transformation of experimental teaching as examples,the teaching practice research is carried out and the research process is carried out.Evaluation,reflection and summary,further verifying,revising,perfecting and proposing strategies for high school chemistry experiment teaching guided by the core literacy of the chemistry discipline,providing valuable references for improving high school chemistry experiment teaching.
