Integrated Teaching Design And Practice Of "Teaching,Learning,and Evaluation" In Junior High School Chemistry Based On Core Literacy

On March 25,2022,the Ministry of Education of the People’s Republic of China issued the Chemistry Curriculum Standards for Compulsory Education,which put forward the essential core quality of chemistry for junior middle school students.The new curriculum standards require the establishment of a scientific view of evaluation,the adherence to the orientation of core literacy,the development and strengthening of process evaluation,and the improvement of terminal evaluation.Therefore,through the integration of "teaching,learning and evaluation" to achieve the development of junior high school chemistry core literacy is the only way to the new curriculum reform.By reading literature,this paper understands the research status and shortcomings of the integration of "teaching,learning and evaluation" at home and abroad and its research status in chemistry teaching.Combined with the investigation and existing problems of the integration of "teaching,learning and evaluation" in junior high school chemistry teaching,this paper determines the research topic and analyzes the research significance and value of the topic.This paper takes the development of students’ core literacy as the fundamental purpose,combines the integration of "teaching,learning and evaluation" with the core literacy of chemistry in junior high school,and chooses two courses of "Caring for Water Resources" and "Water Purification" as examples for teaching design.Study the curriculum standards,analyze the quality of teaching content,formulate teaching objectives,teaching and evaluation objectives before class,design targeted homework,students’ classroom performance evaluation form and teachers’ classroom teaching evaluation form based on specific teaching content and teachers’ evaluation opinions.On this basis,the students in the experimental class and the control class are taught.After the end of the classroom teaching practice,the post-design test paper was used to conduct a quantitative analysis of the practical effect.SPSS27.0 was used to conduct a statistical analysis of the chemistry scores of the experimental class and the control class,and the development of students’ core literacy of each subject was analyzed through the graph data.The results show that the integrated teaching mode of "teaching,learning and evaluation" is conducive to establishing students’ self-confidence and improving their interest in exploration,thus promoting the development of students’ core chemistry literacy,and helping teachers effectively detect students’ learning situation,which has a certain effect on the improvement of academic performance.This teaching mode conforms to the educational reform,can promote the development of students’ core quality of chemistry,and can provide reference for the implementation of the integration of "teaching,learning and evaluation" by front-line teachers in junior middle schools.
