Research On The Application Of Guided Inquiry Modeling Teaching In Senior School Chemistry

It is clearly provided that the core accomplishment should be implemented in the first-line teaching in the new curriculum standard.However,in the first-line teaching,teachers always have limited experience in modeling teaching activities,and more theoretical support is needed to implement model cognitive accomplishment in teaching activities.Mainly through the reading of literature,it is found that MBI teaching mode is a hot topic in foreign teaching practice,while China's modeling teaching practice focuses on teaching strategy research,without defining the mainstream teaching mode.This study aims to find out the connotation and current situation of modeling teaching through literature study,investigation method,interview method,action research method and other scientific research methods,to build a guided inquiry modeling teaching model,to test its effectiveness in modeling teaching practice,and to provide more experience and suggestions for modeling teaching of chemistry discipline.In order to achieve the purpose of the study,three aspects are studied.First of all,through self-designed questionnaire survey to understand the current situation and views of front-line teachers' modeling teaching,through interviews to understand the views of middle school students on chemistry learning activities in front-line classroom.Second,based on the theoretical basis and the actual situation of the investigation,the teaching model of guided inquiry is constructed,and the teaching design is based on the relevant content of the "principles of chemical reaction" module.Research three,choose a senior high school sophomore ordinary class teaching practice.After the completion of the practice,the effectiveness of the model is tested from three dimensions: chemistry learning achievement,chemistry learning interest and model thinking by using the questionnaire of chemistry learning interest of senior high school students and model thinking test volume.Through the research,the main conclusion is drawn:(1)The questionnaire survey found that the front-line teachers' model concept has been expanded,the types of models are no longer limited to the material model,the nature of the model is no longer limited to the physical simulation of the prototype,more and more teachers apply modeling teaching in the new teaching and review class;(2)Based on the theoretical study and practical investigation,this paper constructs the guided inquiry modeling teaching,and expounds the teaching requirements and characteristics of the modeling teaching mode from the teaching objectives,teaching conditions,teaching contents,basic teaching processes and teaching means.The basic links of guided inquiry teaching mode are: problem situation,model representation,model modification,model construction,model application,evaluation and reflection.And through the statistics of the number of models in the textbooks compiled by the People's Education Press,and the analysis of the characteristics and teaching needs of the chemistry discipline,it is determined that the focus of chemistry teaching content in senior high school is three types of theoretical model,material model and cognitive model,and three types of models are selected for teaching design in the module of principles of chemical reaction.(3)guided inquiry modeling teaching can improve students' chemistry learning results and model thinking ability to a certain extent,can help students to carry out language expression,analysis and comprehensive ability training,and enhance students' interest in chemistry learning.The practice has proved that the model teaching mode of guided inquiry is helpful to cultivate students' model cognition accomplishment and is an effective teaching mode.
