Research Of "Hydrolysis Of Salt" Teaching By Interactive Intelligent Courseware

The reform of new curriculum advocates people-oriented, education shouldteach learners how to learn, interesting and methods, self-learning ability, and thehabits of thinking than the book knowledge are more valuable, it also asks for teachersto change the single and traditional methods of teaching,"Hydrolysis of salt" is alwaysa teaching focus and difficulty of teaching and learning in middle school, and it is basedon the understanding of the micro level. However the traditional teaching methodsgeneral with "macro-surface",which is difficult to show the microscopic particles andthe reaction, resulting in the students cognitive difficulties.Therefore, the authorproposes to make use of the information technology to reform the teaching method of"hydrolysis of salt ".Under the guidance of modern education theory and comprehensive analysis ofmaterials, the author uses Flash software to develop the courseware of " hydrolysis ofsalt", which is interactive, intelligent. Contains teaching courseware, animationresources, video resources, Learning resources, mind map, and classical test content,simulation of the motion of particles and change in aqueous solution, at the same time,let students experience the process of hydrolysis of self construction. To complete theteaching design and implementation, through the pre-test and post-test, and interview,confirmed that the teaching courseware of "hydrolysis of salt" has certain teachingvalues.This study includes seven parts, the main contents are as follows:The first part explains the reasons. To analysis teaching the value of "hydrolysis ofsalt", marshaled the literature review of teaching methods, expounded the contents andmethods of the research.The second part analyses the teaching of "hydrolysis of salt". Analysis of teaching includes the teaching content and the students, the threefold representation of"macro-micro-symbolic" should be teaching.The third part is the overview of interactive intelligent courseware. Introduction ofthe meanings and characteristics of Computer Assisted Instruction, the feasibilityanalysis of the topic includes hardware and theoretical basis,expounded the coursewareshould be adopted teaching strategy and the key problems need to be solved.The fourth part develops the teaching courseware. The courseware should followthe principles, the courseware content is displayed, focuses on the usage and effect ofanimation resources.The fifth part is teaching design. To explore the basic knowledge of students,designed the first class and the two class of teaching plan.The sixth part is teaching. Through classroom observation, student feedback, andteacher feedback test using interactive intelligent courseware for "Hydrolysis of Salt"teaching has certain superiority.The last part is conclusion and prospect. Pointed out the shortcomings of the study,the research puts forward the prospect.
