Research On Classroom Teaching Based On Handheld Technology And Simulation Software To Promote The Development Of Core Literacy

The "Ionic Balance in Aqueous Solutions" contains the ionization of weak electrolytes,the hydrolysis of salts,and the dissolution balance of poorly soluble electrolytes,and it is an extension and intensification of the knowledge of "chemical equilibrium".The knowledge involved in this chapter is closely related to the view of chemical microparticles,and the content is relatively abstract.However,traditional teaching methods cannot be presented intuitively,which hinders students' knowledge of knowledge to some extent.On the other hand,with the implementation of the new curriculum standard,the development of students' core qualities has become the purpose of teaching,and deep learning is an effective means to develop students' core literacy.After consulting the literature,the author found that there are many researches on handheld technology and simulation software at home and abroad,but few people use the two together to apply to chemistry classroom teaching.Therefore,this study intends to combine handheld technology and simulation software to present the change of microparticles in solution in both macroscopic and microscopic aspects,reduce students' cognitive difficulty,help students to conduct in-depth learning,and promote the development of core literacy of subjects.The full text includes the following five parts:Part ?: Explain the background and significance of the research,review and sort out the data,summarize the research status at home and abroad,and explain the purpose and significance that this study will achieve.Part ?: Explain and define the concept and use of handheld technology and simulation software.Part ?: Through the literature and the status quo research,formulate the corresponding classroom instructional design.Part IV: Empirical research.The experiment and teaching design of this study were applied to practical teaching,students were followed up,and the results of the survey were analyzed.Part V: Summarize and reflect on the case.
