The American society scientist sorrow Moran pointed out that the  PPT is the 21 st century new esperanto, Bill Gates to the human biggest contribution is his creation of the human social communication esperanto PPT. the great contribution the Bill Gates made to mankind is that he created the esperanto PPT of the human society

The world famous slides sharing website (http://www.slideshare.net/ above), a material on it said, at present on the world, every day at least 300 million people watching a PowerPoint (hereinafter referred as PPT). We have no need to investigate the data's Accuracy, at least we can see all around us, PPT has become the important learning and communicating the information technology tools, From international academic meeting to the medium-sized school classroom teaching; From the investment project report of millions of dollars to decide fate demonstrated the 5 minutes to apply for a job, Whether people realize that the PPT is wonderful or not , it has affected the study, work, and career and life of the speaker and the audience

1. Visual thinking and expression

people often use of words and language to express ideas, visualization refers to the different speaker of the thought mainly through the can see the pictures, the graph way transmission. Mainly used for teaching and because PPT is mainly used in meeting and other occasions, at least two causes special need to be paid attention to visual thinking and expression:

First, time reason, in the process of speech, PPT is operated by the speaker, cooperate the speech manipulation and flip, audience can't control their reading time. So, PPT seeing audience PPT, and not as reading when word can carefully taste and repeated browsing with thinking. people read the writing is linear, and at the same time will read the abstract text symbols in his own mind into meaning understand, need certain of time; And people look like instantaneous and at the same time into meaning understanding, reading comprehension of the image faster than words quickly. At the same time, it is also report and the characteristics of the classroom teaching of environmental requirements and have no time to let the audience one read it carefully screen above. So, ask the speaker to large chunks of text or rich thought into visual images, PPT don't need to express all parties as word (you can consider burn PowerPoint to DVD so that you can play PowerPoint on DVD or TV)

The designing and speech the effect of PPT will directly affect the speaker's teaching effect, how to design a high quality teaching PPT? Below I conclude that the seven fundamental principles:

2. The overall design

In the teaching activities, PPT is a media tool transferring the thought and information between the speaker and audience. Whether a class is wonderful or not, the key factor is the speaker not tool, can't put the cart before the horse, don't regard the PPT design is more important than content and the audience. The speaker design teaching, first of all the attention to your audience, pay attention to your speech content, and then, according to the need of teaching, according to the actual needs of teaching situation, flexibly design and use PPT, the goal was to use PPT to promote and improve the teaching effect.

In the teaching, PPT can realize two functions, the first function is a visual aid tool, to support the speaker lectures; The second function of PPT is independent of the media, or as a reading, transfer the speaker thoughts or teaching information, learning to read for learners. The general teaching activities, speaker with PPT is mainly use the first function.

Common misunderstandings: many speaker just PPT to write, use as a long speech, without full speech alternative PPT to play in the process of teaching in PPT report visual auxiliary function. This leads to the audience often try to read text on screen PPT speech, interference and spread the audience to the attention of the speaker I speak.

3. The perspective-taking

Don't get used to only according to your idea, you have to know the design PPT is for the audience,  the audience is god, your PPT is always for audience service, so in the design, don't be self-centered, from the point of view of the audience to transposition thinking how to design PPT.a small tips: when you making a teaching with PPT, and you can not exactly control the slideshow time, so you can try PowerPoint to video tool to change and convert PowerPoint to video format and let it play automatically according to your time setting.

Common misunderstandings: in his own speaker on a computer screen, no matter design PPT font size, color, and pictures of the details see clear, but at the meeting, the projection put PPT to the wall or the screen, the listeners in the back is a confused. Remember, the audience is not sitting at the table looking at your PPT.
