Research On Teaching Design Of Chemistry Review For Senior High School Based On Model Construction Theory

"Evidence reasoning and model cognition" is one of the core qualities of middle school chemistry.The new round of teaching reform emphasizes that students should understand the important role of model construction in learning and scientific research.Model construction has also become teaching research in recent years.Hot topic.In teaching,Teachers based on the teaching content context,students' cognitive perspective,based on the nature of problem-solving,focusing on student-oriented development to construct a certain thinking model,so as to improve students' ability to understand the world.Due to the guiding role of the college entrance examination,the time for high school chemistry review is short.Teachers pay attention to sea tactics and lack the cultivation of students' core literacy,which restricts the development of students' personalities.The literature research,found that the teaching design based on model construction of high school chemistry review is few and not given.The third year of high school chemistry review is how to use model construction for instructional design.Therefore,under the guidance of the model construction theory,it is significant to carry out the teaching design of high school chemistry review and cultivate students' higher-order thinking logic.This article uses the literature research method to sort out domestic and foreign teaching research,finds the deficiencies of the research,and summarizes the relevant theoretical basis as support to further understand the theory of model construction;adopts the case research method to modify and integrate through its teaching cases.The operation steps of teaching design for senior middle school chemistry review are studied: teaching content analysis-information integration-model preparation,analysis and construction-model application-model feedback five steps.Transform these five-step design links into the basic process of teaching design for the third year of chemistry review,and further integrate analysis,modification,and perfect model construction,and compile a review of high school chemistry based on image problems in ion balance,chemical process flow review,and organic chemistry inference topics.Reviewing the teaching design case for the third year chemistry teacher to provide operability and case demonstration for the teaching design of the model construction of the senior chemistry teacher.And use the teaching design under the model construction theory to carry out educational practice,and then test the two classes taught by the test question evaluation research method,survey the test students,and compare the test results to understand the students' cognition and use of model construction Circumstances,the promotion of senior middle school chemistry review,etc.The research shows that: first,it can realize the teaching design of high school chemistry review under the model construction theory,and summarize the basic steps and case demonstrations for the use of model construction in the teaching design of chemistry review in high school;second,in teaching practice,students learn to transfer the application of model construction thoughts Senior three chemistry review improves the efficiency of review,enhances the accuracy and speed of answering questions,and improves students' chemistry subject literacy;third,the teaching design guided by model construction has deliberately changed the classroom teaching mode of senior three chemistry review through scientific methods Study the teaching of chemistry subjects and promote the professional development of teachers.
