The Design And Research Of Chemistry Classroom Problems To Solve The Driving Problems In Teaching

"Ordinary high school chemistry curriculum standard(2017 Edition)" was promulgated at the beginning of 2018,to develop core literacy curriculum standards of chemistry as a subject,construct the development objectives of high school chemistry curriculum core literacy of students in Chemistry Teaching in comprehensive,that should pay attention to the creation of real and valuable problem situation,promote the formation and development of students the core quality of chemistry.In this context,how to implement the requirements and suggestions of curriculum standards and how to better solve problem solving problems in the context of the new round of curriculum reform are put forward.The purpose of this study is to explore the general characteristics of the driving problems in chemistry classroom teaching,the characteristics of good driving problems,the presentation of driving problems,the design models and paradigms of driving problems,and the specific case verification and improvement of the drive through the literature and case design.Model to guide the design of middle school teachers pay attention to driving problem in teaching,and provide a general design method and process of driving problem,finally make teachers master the design of driving problem,promote the students' ability to solve the problem of classroom teaching and enhance the ability of thinking.The paper is divided into five parts.The first part discusses the research background,research objectives and research contents.In the second part,we summarize the problems of "problem","problem solving"and "driving problem" through literature review.The concept is defined,and the current situation of problem solving teaching in China and the value of driving problems are studied.The third part is the theoretical basis of the research.This research is conducted under the guidance of learning motivation theory and problem solving theory.The fourth part of the thesis is the theoretical and practical research.It puts forward the design model of the driving problems in the classroom problem solving teaching,discusses the characteristics of the good driving problems,and expounds the various parts of the model in combination with the specific teaching case fragments.In the part of practical research,the teaching contents of "material quantity review course","chlorine gas nature" and "ion reaction" were selected as teaching contents.The role of driving problems in cultivating students' core literacy,the design of driving problems based on the history of chemistry and experimental operation were discussed respectively,and the teaching was carried out.The design of the driving problem in the course was reconsidered.The fifth part of the paper combs the research results,and points out the shortcomings in the research.By using literature research,action research and case study,this paper designs a general model of driving problem design in chemistry classroom teaching through about two years' study time,and designs the related teaching cases by using the model.In the analysis and application of the case,it discusses the rationality of the model step by step.The design of driving problems in chemistry classroom teaching provides a train of thought.
