The Ion Balance In Aqueous Solution,Based On The Technology Of Handheld Teaching Design

The chemical equilibrium theory occupies a very important position in the chemical reaction principle, important theory optional4the third chapter "balance" ion in aqueous solution in the ionization equilibrium hydrolysis equilibrium, precipitation dissolution equilibrium is to undertake the principle of chemical equilibrium version of high school chemistry teaching. In this part of the content of inquiry teaching design, this study using handheld technology to replace the traditional experiment, conventional experiment by modern teaching technology, and designed the corresponding instructional design on the basis of it, the aim is to cultivate students the particle concept. At the end of the study, analysis of the advantages and disadvantages of using handheld technology to experiment teaching, and thus to the reflection, the purpose is to provide a set of innovative teaching ideas for teachers.The full text altogether includes five parts:The first part expounds the value selected topic basis, research current situation, research purpose and research.The second part expounds the theoretical basis of this study, laid the theoretical basis for research.The third part is the review of the related literature, summarize and reflect on the existing on handheld technology experimental case, then designed the experiments for this study.The fourth part is to formulate the corresponding inquiry experiment and teaching design for the research content.The fifth part is the conclusion and the limitations of this research. A brief overview of the main conclusions of this study, provide a reference for the future teaching.
