When the presentation made by PPT is used in lectures (lectures, speeches), it is often difficult to see it at a distance. The reason for this is that the venue of lectures (lectures, speeches) is not considered when PPT is made. Generally speaking, if the audience is in an environment with more than 100 people, the font size should be as large and 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, attention should be paid to the color matching of the presentation.

1, the color of the text should have a big contrast with the color of the background, which is easy for the listener to see the text, images and graphics clearly, so as to achieve an intuitive effect. Try to avoid the similar tone of the two, thus causing the effect of not seeing the text and images clearly.

2. The background color should be combined with the season of the content. For example, the lecture is held in summer, and the background color should be cool and refreshing, with patterns such as ice and snow to make the listener feel a little cool. If the lecture is held in winter, the background color should be as warm as possible and matched with patterns such as sun and flame, so that the listener feels warm.

Third, attention should be paid to the audience

1, according to the age structure of the audience, if the audience is a primary school student. According to Piaget's children's cognitive theory, primary school students are in the stage of concrete operation. Abstract thinking is not developed enough, so we should insert as many cartoon pictures (dynamic and static) related to the lecture content as possible and match them with necessary sounds to increase the visual and auditory intuitive effects 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, pictures, texts and sounds should be included in the courseware as much as possible, and some video files can be selected when conditions permit. For people with 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 or wrong writing of bullets and numbers of knowledge structure 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 and there are many words, and the lecturer speaks quickly. The lecturer has not finished taking notes, and then he enters the second presentation. The note taker just sighs for not having finished taking notes, and the listener wanted to make a complete note, which leads to imperfect notes and even no notes. On the other hand, you are too busy taking notes to listen to what is being taught. 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 making too monotonous.

We emphasize that PPT courseware should not be too flashy, which will take the lead, but at the same time, it should not be too monotonous. Every slide has the same background, pattern and color, and lacks individuality. With the increase of lecture time, the listener will feel that it is just 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 to reserve, and combine them when making courseware, so as to achieve the combination of static and dynamic, change the color, increase the visual effect, and then improve the interest and efficiency of learning.

Six, should pay attention to distinguish between lecture notes and lecture notes.

Generally speaking, courseware made by PPT has lecture notes and lecture notes, so it is necessary for us to distinguish their differences in the production process in order to achieve the expected results.

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

2. If the prepared lesson plan is passed PPT.

Designed as PPT courseware for classroom teaching. So generally speaking, the lecture 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 correspond to the content overview part to present a reasonable logical framework of content. Usually, multimedia can be used to achieve better teaching content display effect.

4. Practice, summary and extension

This part is the consolidation, summary and review of this lesson. Usually, it is necessary to practice and 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.
