Instructional Design And Implementation Of "Chemical Batteries" Based On Conceptual Construction

The chemical battery as an important part of high school chemical theoretical system,is of great significance to the development of students.Advances in the study of science and education endows high school teaching with new meaning to correct errors of the current system.Not only can help students assimilate basic knowledge and training basic skills,but also can improve students' Scientific Literacy,the instructional design and implementation based on conceptual construction is.Helping students' character development and providing the key to development and ability for students realistically.This thesis includes the following six parts.Part ?:First of all,this paper analyzes the problems of the current teaching system of chemical batteries and the urgent requirment of instructional design of chemical batteries based on conceptual construction.Then an overview of "Chemical batteries" Based on the Construction of Idea was provided to analyze the present situation of the study of concept construction and the teaching of chemical battery based on the conceptual construction.Last but not least,we designed the purpose and tasks of the study.Part ?:A review on the instructional design.Part ?:An analysis of teaching contents.First,analysizing the status and role of "chemical batteries"in curriculum and textbooks,then analysis of "chemical battery" the value of knowledge was come up,finally,determining the kemal concept framework of chemical batteries based on the basic chemical concepts construction.Part ?:An analysis of students' learning situation.Analysizing the preconception and misconception of students through pretest paper,semi-structured interviews and interviews with teacher.Part ?:Instructional design and implementation of "Chemical batteries" based on conceptual construction.Testing the teaching effect with homemade test volume and analysizing the results using SPSS and WINSTEPS software.Part ?:Based on this thesis,the author put forward the research conclusion and corresponding solutions of the problems in teaching,summarize the research problems and shortcomings,and design the next research plan.The innovation of this research is that set a new perspective of the characteristics of the chemical battery based on the construction of teaching concept.To construct the concept teaching,author puts forward a chemistry battery teaching method based on concept construction and two instructional designs of chemistry batteries.
