When PPT presentations are used in lectures (lectures, speeches), it is often difficult to see them from a distance. The reason for this is that the venue for lectures (lectures, speeches) was not considered when doing PPT. Generally speaking, if the audience is more than 100 people, the font size should be as large as possible and as bold as possible. If it is held in a standard classroom with about 50 people, the font size should be moderate, so as to avoid the effect that people who are far away can't see it.

Second, pay attention to the color matching of the presentation.

1, the color of the text should have a great contrast with the color of the background, which is convenient for the listener to see the text, images and graphics clearly and achieve an intuitive effect. Try to avoid the similar tone of the two, which will lead to the effect that the words and images cannot be seen clearly.

2. The background color should be combined with the season of the content. For example, if the lecture is held in summer, the background color should be cool, and patterns such as ice and snow should be used to make the listeners feel a little cool. If the lecture is held in winter, the background color should be as warm as possible, with patterns such as the sun and flames to make the listeners feel warm.

Third, we should pay attention to the audience.

1. Judging from the age structure of the audience, the audience is primary school students. According to Piaget's children's cognitive theory, primary school students are in the concrete operation stage. Abstract thinking is not developed enough, so we should insert as many cartoon pictures (dynamic and static) related to the lecture content as possible with necessary sounds to increase the visual and auditory intuitive effect of the manuscript, thus stimulating students' interest in learning and improving their learning attention.

If the object is an adult. In PPT presentation, there should be more words and fewer pictures. Sometimes you can add some knowledge structure graphics and so on.

2. According to the knowledge structure of the audience.

For people with relatively low knowledge level, the courseware should contain pictures, words and sounds as much as possible, and some video files can be selected when conditions permit. For people with a relatively high level of knowledge, the knowledge structure in the courseware should be rigorous and orderly, with more words, supplemented by corresponding graphics and pictures. Confusion of bullets and numbers of knowledge structure or writing errors should be avoided.

Fourth, we should pay attention to the capacity of the text in the demonstration courseware.

In the production of PPT presentation, we often see that the layout of the presentation is dense, there are many words, and the speaker speaks very fast. The lecturer entered the second demonstration before taking notes. The note-taker just sighs because he didn't finish taking notes, while the listener wants to make a complete note, which leads to imperfect notes or even no notes. On the other hand, you are too busy taking notes to listen to what the teacher is teaching. Therefore, when making PPT demonstration courseware, the number of words displayed should be moderate, so that the number of words is consistent with the progress of the content taught.

Five, should pay attention to avoid production is too monotonous.

We emphasize that PPT courseware should not be too flashy, it will play a leading role, but at the same time it should not be too monotonous. The background, pattern and color of each slide are the same, lacking individuality. With the increase of lecture time, the listener will feel that it is only a renovation of the text content, and there is no new change in vision, which will cause a boring feeling. Therefore, when making PPT courseware, we should use the system template as little as possible, and usually find more courseware materials for storage, and combine them when making courseware, so as to combine static and dynamic, change colors, increase visual effects, and then improve learning interest and efficiency.

Sixth, we should pay attention to distinguish between lecture notes and lecture notes.

Generally speaking, the courseware made by PPT has lecture notes and lecture notes, so it is necessary for us to distinguish them in the making process in order to achieve the expected effect.

1. If it is a PPT courseware for lectures, just grasp the knowledge structure and the main points mentioned above.

2. If the prepared lesson plan passes PPT.

Designed as PPT courseware for classroom teaching. So generally speaking, class notes should at least include the following parts:

1. Content import

This part usually includes content review, situation or question introduction.

2. The content overview of this lesson lists the main teaching contents of this lesson in a simple and clear way to help students understand the learning tasks and objectives of this lesson. Usually, you can use hyperlinks to connect the content overview with the detailed teaching content, which is also convenient for students to understand the relationship between knowledge.

3. Multimedia teaching content display This is the main part of classroom teaching, which can present a reasonable content logical framework for the content overview part. Usually, multimedia can be used to achieve better teaching content display effect.

4. Practice, summary and popularization

This part is the consolidation, summary and review of this lesson. At ordinary times, we should practice to consolidate the key and difficult points of teaching, and at the same time summarize and put forward the problems that need students to think further.
