Research On Teaching Design And Application Of Chemistry Teaching In Senior One Based On POE Teaching Strategy

The POE teaching strategy is based on the student's standard.The teacher acts as a guide,allowing students to predict related issues based on their existing knowledge reserves and life experience,and then allowing students to generate cognitive conflicts through observation,and finally make reasonable explanations,and gradually guide students to take the initiative The knowledge is constructed to promote the teaching strategy of the efficient development of teaching activities.This article applies the POE teaching strategy to the teaching design of elementary compounds in senior high school and examines the effect of POE teaching strategy application.Firstly,by consulting the relevant literature of POE teaching strategy,Study the current situation of POE teaching strategy and its application in element compound teaching,and define the core concepts;secondly,in the theoretical aspects of constructivism and conceptual change Under the guidance,according to the basic requirements,principles,general modes of chemistry teaching design,the teaching design of chemical element compounds based on the POE teaching strategy is carried out,and the "chlorine" "And its important compounds" and "Iron and its important compounds" are designed to be implemented in the classroom of the experimental class for teaching,and the teaching design of the class is taught by the original teacher.Finally,the knowledge evaluation,questionnaire and Analyze the results obtained in the form of teacher interviews,draw research conclusions and summarize the difficulties encountered in teaching and make corresponding suggestions.Research conclusions:(1)After-class evaluation and analysis,the results of the experimental class have been significantly improved,there are significant differences,indicating that the high school chemistry teaching design based on the POE teaching strategy Conducive to students' understanding of knowledge and improvement of academic achievement.(2)Through the interest and attitude survey questionnaire and interview resules analysis of the two classes,it is shown that the theaching design using POE teaching strategy creates a rich context for students.With the help of experimental teaching,students pay attention to attracting studengts' attention.Students are more willing to be proactive while learning knowledge.Toanalyze and solve problems is conducive to improving studengts' interest and in learing.(3)The POE teaching strategy enables students to act as the promoters of the course,and the teaching activities are carried out around the students.students consciously complete the record of the learning activity sheet,enhance their initiative and the consciousness and persistence of learning chemistry knowledge.Therefore,the POE teaching strategy has It helps to enhance students' chemistry learning subjectivity.
