Based On The Balance Of The 《Dissolution Of The Undissolved Electrolyte Balanced》 The Teaching Research

I learn from the practice that the students in chemistry study often regard the chemical equilibrium, the ionization equilibrium, the hydrolisis balance, the precipitation and the dissolved balance as four independent knowledge to analyze separately and the understanding, but has not unified together properly; to make things worse, the students' understanding of the precipitation and dissolution balance has been apart from other balanced systems seriously. In view of such problems, I want to use the teaching method "Difficult To dissolve Electrolyte Dissolved Balance" to combine the four balanced system organic unions, helping the students to establish the balance thought, based on the balance knowledge foundation, which causes this chapter content and the balance theory to obtain the sublimation.Therefore using the motion research technique to this teaching research is of great significance to the teaching of the chapterPaper is divided into three parts. The first part discusses the basic high school chemistry curriculum requirements:high school chemistry curriculum standards need to be based on the examination outline as a guide, to improve the scientific literacy of students for the purpose. Define the concept of balance, cognitive development research. The second part of the action research method is mainly used to "the dissolution of insoluble electrolyte balance" the process of teaching and research. Include:1, Jilin City high school chemistry teachers in insoluble electrolyte balance of lesson planning and teaching the ionization status of the investigation; 2, Action Research in the Teaching of insoluble electrolytes and methods of application of the basic requirements; 3, dissolved in the electrolyte balance of insoluble Teaching action research. The third part is a summary of later work, reflection and evaluation of results, from the student's harvest, the harvest of teachers, teachers in the teaching methods of harvesting, Evaluation of the summary view for the future of teaching and methods of education recommendations, summarized The mode of teaching practice in a specific application. Finally, the paper studies the problems were discussed and prospects for the future continue to study the direction.In this research, through the design--practice--reconsidering--summary motion research process, each member of the chemistry group keeps on finding problems, solving problems, and perfecting problems. Through the practice processes of the three periods, I have found out a more ideal educational model and teaching method. Whien I have taught the students the dissolved balance of the electrolyte hard to dissolve, the students establish and form the balance thought.As a result, the students manage to deal with smoothly the difficult problems in this chapter. The students can understand and grasp the dynamic state of equilibrium by using the sublimation of the chaper...
