High School Chemistry Class Questions Applied Research

As the new round of curriculum reform attaches more and more importance to students' active and conscious learning,many front-line teachers are increasingly advocating "problem teaching",and question-based teaching is a simple and easy way in problem teaching.The teaching method has gradually become an important direction of chemistry classroom teaching reform.Question-string teaching is a kind of teaching in which the teacher carefully designs a series of closely related sub-questions to form a question string in different modules of the teaching content,and then guides the students to continue to think deeply and let the students' thinking develop further.the way.This study uses some theoretical knowledge about question strings as the basis to carry out applied research on question string teaching in high school chemistry classrooms.The main parts of the research are listed below:Firstly,the concept of question strings,some specific principles of question string design,the types of question strings,and the current research status of question string teaching in chemistry teaching are carefully combed and summarized using literature analysis methods.There are some problems in the design of string,and the related requirements for designing high-quality question strings in high school chemistry classroom are summarized.Secondly,according to different teaching purposes,corresponding cases are selected to carry out teaching design research on related question strings.Before carrying out the teaching design of the question series,the case was analyzed in detail for the status of each case in the teaching materials,the student's academic situation,and the teaching content in the case.To carry out instructional design on question strings.After designing the teaching process,the number of question strings used in each case,the type of question strings,and the role played by the question strings are also analyzed.Thirdly,the question string teaching was applied in the high school chemistry class,and the effects after the question string teaching was applied were analyzed from various aspects such as classroom performance and academic performance,so as to provide some reference for future teaching practice.Finally,based on the results of the study,the conclusions of the study are summarized and a research outlook is proposed.
