Design And Practice Of Chemistry Balance Teaching Based On Core Literacy

The development of students is inseparable from basic education.High school education is to further enhance the comprehensive quality of students,clarify the positioning of high school education,and develop core literacy as the main driving force to actively cultivate students' independent development ability.This requires that teachers' teaching should not only focus on the imparting of knowledge,but also the cultivation of core qualities of the subject.Chemistry is a basic subject,and it has strong practical application in production and life.The content of chemical balance in high school chemistry is highly conceptual,complex and abstract,and is closely related to many chemical production processes.In the test paper,both the students 'understanding ability and the students' core chemistry qualities are tested.Have presented considerable challenges.How to gradually teach the core literacy of students while teaching theoretical knowledge in the teaching process is already a practical problem that most front-line teachers have to think about.Through interviewing teachers,analyzing academic conditions,interpreting course standards,and combining core literacy analysis chemistry balance teaching goals on the basis of three-dimensional goals,this paper proposes a teaching strategy for cultivating students' core literacy,and practices by designing chemistry balance cases.In this process mainly done the following work:Interviews with first-line teachers found that some teachers 'cognition of core literacy is not clear,and more attention is paid to the teaching of knowledge in classroom teaching,while neglecting the development of students' core literacy.In the aspect of chemistry balance teaching,most teachers believe that the main reason for students 'difficulty in learning chemistry balance is the abstraction of the concept of chemistry balance and the lack of students' reasoning ability.Through teacher interviews and student academic analysis,the current situation of chemistry balance teaching in some high schools in Henan Province was investigated,and chemistry balance teaching goals were formulated.On this basis,the teaching strategy of chemistry balance under core literacy was proposed: creating teaching situations to stimulate students Learning interest;constructing students' particle view and developing students' core literacy;constructing models to promote students' thinking ability;establishing students' balance view and enhancing subject literacy ability;cleverly setting up problem chains to promote the construction of students' knowledge framework;establishing correct classroom value orientation.Design chemistry balance teaching cases based on chemistry balance teaching strategies,and carry out teaching practice at Q High School in Kaifeng City.Using SPSS for data analysis,the significance level of high school(5)and(6)classes is 0.561,there is no obvious difference,and it can be used as a parallel class for teaching practice.Select the high school(5)class as the experimental class to adopt the new teaching design for teaching practice,and the class(6)as the control class to use the traditional teaching design for classroom teaching.After the implementation of the case,the data analysis of the student's achievements showed that the chemical balance teaching results showed that:(1)In the classroom practice,through observation of the experimental class and the control class,it was found that the experimental class students had more classroom interactions during the class,the response was faster,and they were able to Ask some meaningful questions.(2)The average score of the test questions of the experimental class is higher than that of the control class,especially the microscopic particle question and the calculation question have a certain improvement.(3)Interview students found that students liked the new instructional design and strengthened the ability to collaborate with classmates in the classroom.It has been proved by practice that the teaching practice based on the core balance of chemistry balance has played a positive role in cultivating students' core literacy.
