Research On Designing Problem Of Chemistry Textbook Of Middle School

In the chemistry teaching of middle school , textbook is the most important resources for teachers'teaching and students'learning, its design will directly interfere with the students'study.In order to promote change of students'learning style and training student'problem consciousness and innovation ability, textbook's design must industriously set up problem situation, through which develop students'proactive study. The text falls chemistr -y textbook'problem into unit problem and section problem, which the design of each part problem put forward academic conceptualization. On the theory research basis we analyse design situation of unit problem and section problem of chemistry textbook of prevailing different editions of middle school.We make an action research for the problem of chemistry textbook in the use of practical classroom teaching.There eight parts in the full text.In the first part we propose the problem.This part sets out the new curriculum reform and the teaching practice has put forward demands to the textbooks ,thus make the significance clearly of this study.The second part is the study of the status quo.This part of the existing te-xtbooks about the study to explore activity is reviewed,and in this find out a breakthrough in this study.The third part presents the purpose, approach and methods to complete this study.Part IV is the academic conceptualization of unit problem design of middle school chemistry textbooks.The theory of the design of unit problem contains four aspects of function ,features ,contexts attention and express present ,which make in-depth study for each part.The fifth part is the academic conceptualization of section problem design of middle school chemistry textbooks. The theory of the design of section problem contains four aspects of function ,features ,contexts attention andexpress present ,which make in-depth study for each part.Part VI is case analysis of chemistry textbook of prevailing six editions of middle school. In this part ,we analyse the problem of chemistry textbook of prevailing editions through two dimension of unit problem and section problem.The unit problem mainly study problem'design of RenJiao Core Course edition,LuJiao edition,ShangJiao edition, and contrastive study the case for aspects of function ,features ,contexts attention and express present.The section problem study all editions, and the study is contrastive study the case for five aspects of function ,features ,contexts attention , kinds and express present.Seventh part is the study of problem'spendable practical instance of textbook of prevaili -ng editions.In this part we choose the textbook of LuKe Core Course edition 1, and we adopt listening to the teacher in class to find out teachers how to use the textbook in classroom.Through recording the class teaching, we can observe the situation of teacher'teaching ,which we can know how many problem is from the textbook and how many from the teacher'design.We also understand the manner and use of the students for the textbook.Through practical instance, we may find the utilization rate of textbook'problem, and understand the point of view and suggestion of the teacher and the student from interviewing them. Understanding the practical teaching is offering some instructive proposal for our design theory of textbook'problem , and improve it.The eighth part is the problems and prospects. In this part we summarized our research drew a conclusion, and put forward some suggestions about the design of the inquiry and the development of inquiry. Finally, we point out the inadequacies in this study, and we points out the direction for future research, too.
