Digital High School Chemistry Experiment Teaching Case Development And Applied Research

In order to skillfully take advantage of information technology to make up for the traditional experimental short board, so that digital experiment in chemistry teaching can fully play its role, this paper combines the research results at home and abroad, the first of the advanced digital experimental teaching model research, comprehensive comparison of after the advantages and disadvantages of a variety of teaching modes, weaknesses, developed four digital experimental teaching case: one study of digital sensors pH purple cabbage pigment discoloration based, the second is based on the pH sensor explore acetate hydrolysis, the third is explore ethyl acetate-based colorimetric sensor hydrolysis Fourth explore temperature and concentration on the hydrolysis of copper sulfate-based digital sensor. Fully integrated digital sensor test content and test the characteristics of rationalizing experimental device, experimental optimization process, so that the experiment related change is more clear and intuitive, more quantitatively demonstrated.During classroom practice research, a reasonable choice of subjects, to develop research programs to further deepen the psychology of, and thus the case for commissioning, optimization, upgrade; further attitude of digital experiments visits from classroom practice to study the digital test case application, the impact on student learning and attitudes produce their effects.The author found that digital experiment can be achieved experimental phenomena "static" to "dynamic" change, digital experiments carried out, allowing students observed dynamic changes of chemical reactions of some parameters, not only focus on results, more attention Chemistry experiment procedural; in addition, for the same problem, you can multi-angle observation of different phenomena, the students divergent thinking, which will help students to develop knowledge of the formation;Finally, process improvement and experimental operation of the instrument to stimulate students’ innovative consciousness.
