The advent of the information age gave birth to the traditional teaching mode to modern teaching way to turn Change. In changing the way of Teaching process, PowerPoint Teaching (below” The advantages and disadvantages of the existing teaching PPT) became the focus of the discussion education, PPT to teach earning and teaching quality the contradictions between intensified

On the other hand, PPT teaching has also the complexity of the problem, the seriously influence the quality of teaching. In recent years, as the popularization and application of information technology, education media also more and more incline to more media-oriented. With computer aided multimedia classroom teaching the new way of teaching education is causing more and more attention. PPT teaching the new teaching mode for the universities is acceptable, and development and promotion is strong. However, in the process of teaching PPT, there is this or that kind of problem, especially the science and engineering teaching, because of its subject characteristics, teaching structure, the different ways of teaching, but also appeared a lot of the complexity of the problem. But, for PPT teaching to the solution of the problem, PPT research on the effect of teaching has been the debate, arguing.

PPT made problem

In PPT teaching, PPT making is a university skill. If PPT making good, rich in content, highlight key points and difficulties, and do not break concise, easy to be understood, it can improve the students' study result, improve the quality of teaching and the teaching effect. If PPT production well, too numerous or too inflexible, will greatly affect the quality of classroom teaching. In the interview and investigation of the process, we found that there are many science teachers is not standard and not make PPT with multimedia, some of teachers didn’t make PowerPoint presentation, but there are many practical ppt makers software for you, we can turn PowerPoint to flash video and make it freely. If you have some wonderful PowerPoint presentations and want to share them on the Internet, the best way to realize it is to convert PowerPoint to flash. Because the Flash format is the best option to share and distribute your PowerPoint presentations and anyone can easily view a PowerPoint presentation using a standard web browser, as more than 95% of all browsers have the Adobe flash plug-in already installed.

The reflection of the innovation for PPT teaching

PPT teaching in colleges and universities is not new but for PPT teaching not the advantages and disadvantages of the verdict, according to interviews and survey in PPT existing in the teaching of the five questions, and based on this, reflection, and put forward some rationalization proposal, the hope can give full play to the PPT teaching to the best advantage, make up for the defect of the PPT teaching, foster strengths and circumvent weaknesses, for the improvement of the teaching in colleges and universities PPT improve the teaching quality of the provide some reference. 1. The reasonable use PPT for teaching, prevent the blindness of use PPT, when we download some PDF teaching content and want to export it to PowerPoint, we can try to convert PDF to PowerPoint with it.

In classroom teaching, and not all teaching need to use PPT, teachers should according to the actual needs of the teaching content, teaching or traditional determined choice PPT blackboard teaching, or put the two combined, in order to avoid the blindness of use PPT. Admittedly, PPT teaching and traditional teaching has many advantages compared to the blackboard, but, PPT also exist defects and shortcomings of the teaching, this is in our analysis of the above has also seen, therefore, it is necessary to put the two kinds of teaching methods used in combination, teachers are using PPT teaching process, to fully absorb the advantages of traditional teaching, the teaching and traditional teaching PPT organically, to realize "complementarily and complement each other", must not superstitious or relying too much on PPT, and to properly deal with the traditional teaching method and the teaching methods of the modern PPT relationship, do it from each director, bring out the best in each other. In the interview and investigation of the students of science and engineering process, many students will be mentioned two teaching methods combined use of teachers, the effect of classroom teaching will be good, teaching mode is easy to students accepted, so, simple to use PPT teaching is not necessarily the best, the teacher must according to the practical courses and teaching content characteristics.
