Research On The Application Of Cooperative Learning In Junior Middle School Chemistry Group From The Perspective Of Core Literacys

The study of chemistry in junior middle school is the extension and connection of natural science in primary school and it is also the preliminary study of chemistry.It is of great significance to study how students learn chemistry,what teaching tools and media teachers use it to make students have strong interest in chemistry,and how to adopt effective teaching strategies in class.However,the traditional classroom has the problem of "what teachers teach and what students learn",which is not conducive to the development of students' awareness of cooperation and comprehensive ability.Group cooperative learning is an effective teaching method for students to explore their own learning through cooperation.The research on the teaching application of group cooperative learning from the perspective of chemistry core literacy is in line with the requirements of the new curriculum reform,which is conducive to promoting the overall development of students.This paper mainly includes the following six parts:The first part:introduction.First of all,this paper expounds the research background of group cooperative learning,makes a literature review of core literacy and group cooperative learning,and puts forward the research purpose,research ideas and methods.Research significance and feasibility analysis of this study based on the conclusion of literature review.The second part:analysis of the theoretical basis and basic connotation requirements of the chemical core literacy in junior high school.Based on the literature review,the concept of "core literacy" and "subject core literacy" is defined.Based on the development of Chinese students' core literacy,junior high school chemistry curriculum standard and senior high school chemistry subject core literacy,the paper draws on the research methods of Beijing junior high school science research institute to analyze the connotation of junior high school chemistry core literacy The basic connotation of literacy includes "macro micro combination","conservation of change","symbolic representation","experimental innovation" and "scientific environmental protection".The third part:the theoretical basis and model construction of junior middle school chemistry group cooperative learning from the perspective of core literacy.Firstly,the concept of "cooperative learning" and "group cooperative learning" is defined.Based on the theory of research group cooperative learning,combined with the basic connotation of junior middle school chemistry core literacy,the basic teaching mode and process of junior middle school chemistry group cooperative learning from the perspective of subject core literacy is designed.The fourth part:the investigation,analysis,specific methods and approaches of cooperative learning in junior middle school chemistry group from the perspective of core literacy.First of all,the questionnaire is designed to investigate the basic status of the cooperative learning in the internship school.Secondly,the questionnaire data statistics and analysis are carried out to find the existing problems.Finally,the specific solutions and ways are put forward to promote the effective development of cooperative learning in the group.The fifth part:research on the cooperative learning practice of junior middle school chemistry group from the perspective of core literacy.Based on the theory of constructivism,using the designed teaching mode and process,we choose three dimensions of chemical practice,chemical cognition and chemical application:"making oxygen in the laboratory","molecules and atoms","chemical formula and valence","law of conservation of mass" to design and practice junior middle school chemistry cases,Before and after the practice,we take achievement test and scale evaluation to effectively evaluate the small combination Evaluate and analyze the effect of learning.The sixth part:results and prospects.This paper summarizes the research practice of group cooperative learning from the perspective of chemistry core literacy in junior high school.It finds that group cooperative learning can cultivate students' interest in chemistry,improve students'comprehensive ability,help students develop their chemistry core literacy ability and improve students'chemistry performance,put forward research deficiencies and prospects on the research content.
