When you think of a typical chemistry classroom, you might envision a professor filling multiple chalkboards with text, equations, and chemical structures, while students write furiously in their notebooks. PPT is one of means of multimedia teaching, it currently is a kind of auxiliary teaching form which is used mostly, especially at some developed areas, schools have been equipped with multimedia teaching equipment, with all of this is the Gospel of the teachers and students, but as a teacher, we can not completely depend on it, be selective to use, to make the teaching in our usual PPT to play a "perfect" effect.

The PPT courseware has own many content such as the text, images, sound, video, animation and so on. in teaching, its main played a large capacity and diverse forms, vivid and lively, intuitive and clear and easy to operate, and other effects.

In the current, PPT technique is quite popular in class teaching, how many people who can really use it well? And the degree of abuse are also common, so, How to make elegant and practical courseware? I talk about some personal experience:

1. The right multimedia, avoid out of control. I like to use pictures, pictures is eye-catching than text. Words are all over the place, and let people stuck in the Wiki data text sea; And good pictures have the effect that make the finishing point, need to take the time to collect and prepare Story to facilitate readers to understand. I am mostly afraid that I pick out a picture that I didn't expect, so I really don't like PPT the dynamic display function, unless special needs, or a diagram into many steps to show, but if need to your PPT to be played automatically, a method you can try to convert PowerPoint to DVD format, and then burn PPT to DVD, you need to use a pile of crap to transfer the gap, only old professor, or special like waste of class time professor just do it like that, this is I have been trying to avoid, is to avoid the uncertainty of speech (lecture) process, it is better succinctl.This integrated approach has proven effective in improving student learning in this course, in which students must master the ability to visualize, manipulate, and refine three-dimensional crystal structures. In materials science, understanding the crystal structure of a solid-state material is often helpful for understanding its chemical, electrical, optical, or mechanical properties.

2. PPT content must be clear at a glance, including short writing, outstanding title, suitable expression, and cooperate with appropriate speeches. If audience needs to read your PPT with effort, this page content is failure. Except few exceptions, PPT shall cooperate with the content of the speaker, and not to provide new content, the distraction. Domestic teaching PPT with too much text, less picture, this may and over the wall means deficiency it. Google is powerful tools for searching images, baidu was beguiled by money.

3 when making the images, video or other material,it must be related with teaching content, To very good "to urge hair" effect, it good for the teacher to teach and students' learning.

4. We should also realize that knowledge course is suitable for PPT teaching, and skilled PPT for blackboard writing to teach, the reason is that process. Skills need to practice, only intended to practice can make people have a basic understanding, for this PPT have a supplementary., Although, PPT has so many dynamic content, can demo process. But without considerable energy and skills is not enough to spot demonstrate the dynamic process, this is PPT as a congenital deficiency of media, also need to pay attention to the content of the user considerations.

Finally, we still have to realize clearly that PPT is lubricant, do not increase the engine itself power; PPT is flame retardants, itself does not reduce the release of energy. Successful speech comes from the grasp of content, Not for a better understanding of the course content, PPT itself won't help us achieve the purpose of teaching. The Key is education evaluation problem, if cannot establish a good teaching evaluation mechanism, is more than of poorly PPT scourge of deep reasons. The lecture level of young teachers, and have nothing to do with PPT.as a university teacher, I thanks for my students for provide me a Powerful tool PowerPoint to flash software in an accidental opportunity, which help me make many effective teaching PPT.

While the SMART Board and Tablet PCs offer new tools for students to master critical skills, they are just two of the tools that Buhro uses. The document camera, a high-quality digital camera that can project photos, books, brochures, transparencies, slides and objects onto the screen, offers him a means of projecting images of the three-dimensional models of chemical structures that have been standard in chemistry courses for decades.
