Research On The Effective And Interactive Opening Mode Of Classroom Teaching Of Different Types Of Chemistry In Junior High School

The classroom teaching process is an interactive process in which teachers and students communicate and develop together.The dynamic generation of classroom teaching relies on real and effective interaction in classroom teaching.Effective interaction in teaching enables students to develop good emotional attitudes and values while acquiring knowledge and skills,processes and methods,so as to better achieve the teaching goals.However,in my work,the author found that junior high school chemistry classroom teaching lacks the awareness of questioning,and there are problems such as few interactions,monotonous interaction methods,limited interaction objects,and insufficient interaction depth.Relevant databases also show that there are not many public reports on the ways of teacher-student interaction in junior high school chemistry classroom teaching and its effectiveness,especially there are fewer related studies on the effective interactive opening mode of classroom teaching.Based on the above situation,this paper consults and analyzes related literature,and on the basis of further understanding the current research status of effective interaction in classroom teaching,researches on the opening mode of effective interaction in classroom teaching of different types of junior high school chemistry.The thesis takes all junior students in the school where the author teaches as the research object.Through questionnaire surveys,classroom observations,teacher interviews,and exchanges,we understand the interaction of students ' classroom learning and teacher's classroom teaching,and then use the designed observation scale to compare different classes.Types of repeated observation,evaluation,and recording of teaching cases in teaching practice,analysis and summary of the effective interactive opening mode of classroom teaching,and designing effective interactive opening mode of new courses,review courses,and experimental exploration courses repeatedly used in teaching practice.The modes are as follows:new teaching class-creating a situation,focusing on questions ? asking questions? "soldier teaching soldiers" ? student evaluation ? summary and improvement;review class-mode 1-recalling old knowledge ? stimulating students' questions ?multiple student answers ? students Comment ? Teacher's comment;Review class-Mode 2——Comment papers?Focus on the problem?Question the reason?Student explanation ? Student comment ? Student summary ? Teacher's error correction;Experimental inquiry class — — Propose questions ? Conjecture and hypothesis ? Design and evaluate the plan ? Student experiment ? Group report exchange?Focus on generative problems?Students explain the reasons?Student evaluation ? Teacher's summary In the process of practical research,compare students' academic performance vertically and horizontally,and observe and understand the growth of teachers and students.The research results show that an effective classroom interaction opening mode can enhance students' interest and confidence in learning,create a harmonious classroom atmosphere and teacher-student relationship,increase the interest and vitality of teaching,thereby improve students' quality and academic performance,and promote teacher professional growth And business improvement.Years of teaching practice also shows that this research has created a higher level of teaching and research teams,and has contributed to the formation of an effective interactive teaching system for junior high school chemistry classes with school characteristics.
