Teaching Research Of "the Structure And Nature Of The Substance" Based On The Information Technology

“The structure and nature of the substance” is an important part of highschool chemistry, it’s from the microstructure constituted of material to study therelationship between structure and nature, It is great significant for letting students toform the value that the nature of the material is determined by the structure.“Structureand properties of crystals” is an important content in “The structure and nature of thesubstance”, Considering the situation that the structure and properties of crystals isabstract, it requires that students have high spatial ability, but the existing teachingmaterial are scattered which can’t fit the actual teaching needs. The author under theguidance of modern teaching theory, using the Flash and Diamond to design interactivecourseware "Metal crystal accumulation mode" and "Common crystal model", thecourseware image shows the contents of rotating of the typical crystal model,accumulating process of metal crystal, cutting crystal cell, coordination number and soon，It’s great reference value to the rest content of “The structure and nature of thesubstance”.This paper mainly includes five aspects of content:The first part introduces subject’s background, development and application status,research purpose, content and research methods.The second part, first define and analysis the advantage of Computer AidedInstruction, Then introduces the learning theory and basic ideas of supporting computeraided “The structure and nature of the substance”, common type courseware ofcomputer assisted instruction.The third part analyzes which content in the“The structure and nature of thesubstance” is suitable for using computers as an aid to teaching。“The accumulation ofmetal crystal”as an example illustrate the basic principle of designing courseware.Finally, it focuses on how to use the courseware embodies related knowledge.The fourth part introduces how to use the courseware guide teaching design of metal crystal and ionic crystalThe last part points out the insufficiency in research and put forward the next stepresearch direction of subject.
