In recent years, with the rapid development of science and technology, more and more the electronic media poured into the classroom, is toward intelligence, and procedural direction. Multimedia combination has been teaching workers the universal attention, however, at present, in the use of various teaching media, some teachers blind pursue high-quality precision instrument media, and to ignore the obvious media, especially the slide projection the use of media, some people even think the slide projection media will be eliminated sooner or later, it is a one-sided view, because all kinds of media has its own function and characteristics.

PPT making slides, it’s typesetting, the effect is very simple to add, in that its production is simple, and easy to master. And flash is different, flash production style protean, can fully designed to all you need any appearance, and can create a very elaborate effect. And flash and its biggest weakness is in the making. Make a slide type flash whether it wants to spend time or energy, are far more than the same effect PPT. And making flash, often also involved in programming problems. Not professional personnel, it is difficult to make to elegant flash slides. Instead, PPT only need simple to learn, can make. But when the teachers want to turn PPT to flash, you can easily make PowerPoint to flash video. This is their advantages. Instead, PPT and flash than its layout is a single, and can only be making slides, can not think flash that almost any production need can be animation, the same, all sorts of effects of the PPT than flash also appear negligible.

In many of the electronic media in the projector function more, the application of the slide show projection teaching is still has certain advantages. slide projector, overhead projector, simple in structure, easy to operation and make some high-quality precision instrument than media, slide projector, overhead projector is appeared old, but its simple structure, easy to operate, the teacher is so easy to use, and as the development of the science and technology progress, slide show projection teaching material method of making has also is varied, is easy to grasp and popularity. First of all, in recent years, photography technology progress day by day, and the camera function continuously improved, operating more and more simple, color photographic materials of improvement, the appearance of digital photography, the production of teaching materials for the slide projection provides a reliable guarantee, people want to get the slide teaching material is not difficult. In addition, the projection of the teaching material production also is easy to follow and low cost.

In the 1990 s, Microsoft developed Power Point (hereinafter referred to as the PPT) software on the world popular. At present, the world everyday at least 300 million people are using PPT, PPT people study and communication has become an important "world language". However, the application of the PPT but there are many drawbacks. Although every day there are countless PPT works born, but most PPT and lack of composition, demonstration works form a single, boring, the hard to avoid the disseminators by bitter. For example, the visual master Edward Taft (Edward Tufte) said: "with PPT for speech is more like a school performance drama: sensationalistic rhythm, slow and simple in form." In addition, because of the negative evaluation PPT there, many rich teaching experience but lack of education technology understanding of teachers even refused to enter into classroom PPT. But, as a kind of important demonstration way, PPT in reality, especially in the teaching of general application on line is the fact that does not dispute. We think that the key to the problem lies not in PPT itself, but in how to improve the design of the PPT manufacture and application level, make PPT effectively promote the education and teaching activities. A, PPT in teaching application and loses in general, PPT is used to design the expert's report, the teacher teaches, the product demonstration, advertisement publicity of electronic slides, make a presentation by computer screen or manuscripts can play the projector

Common computer education PPT design error as people have different computer proficiency, PPT design skill mastery is different, and education concepts, teaching methods of natural differences, makes the current college computer education PPT design has many problems, some problems and even serious effect on the teaching effect. On the basis of teaching practice and summarizes the observation, we can will common computer education PPT design error summarized mainly in the following respects: the first, some teachers believe that, as much as possible image appeared in front of the student help to improve students' perceptual knowledge, thus deepening the understanding of the students depth. But in fact this view is a big misunderstanding. We can also convert PowerPoint to video, And the text, data rational present different, the use of the image data in the teaching material, vivid image at the same time, for instance, you can convert PPT to avi format and upload onto youtube, also unavoidably perceptual strengthens theory weakening, material analysis of built weakened sickness. Limited to specific class, many teachers can only in unit time there were selectively transmission some more students at that time the images, video welcome information, and to professional disciplines of the basic theory of the emphasis is insufficient in, its directly result is course colourful, lectures and students from trumped effective knowledge, few brain thinking degenerates, this is a kind of typical at the shadow and lose the substance of mind and impetuous behavior. Second, teaching time, various content close degree, the computer education PPT courseware design also appeared information is huge, and the lack of new questions to think about time.
