Myth 1: Too much text information.
From the original English meaning of PowerPoint(PPT), Point means "main point", and PowerPoint can be understood as "showing the main point more effectively".
Some teachers simply think that it is enough to copy the main points of the contents of the book to PPT, which we call "textbook moving" Such a page is too informative for students, the focus is not clear, and it looks difficult.
Tips: Illustrated with pictures and texts, it liberates students' eyes.
The essence of PPT lies in visualization, that is, transforming the original obscure abstract text into a vivid scene composed of charts, pictures, animations and sounds, so as to be easy to understand.
Teachers need to change the practice of "copying" and "pasting" and try to summarize the key words and sentences in the teaching plan. You can refer to the following two principles: those who can use diagrams do not need tables, and those who can use tables do not need words. Pictures should be related to the teaching content of this lesson, not for pictures; If there are no charts or tables available, try to divide the text into items, preferably within 5 lines, and don't pile up a long paragraph of text.
Myth 2: Logical confusion
Logic is the soul of PPT! Without logic and hierarchy, PPT can only be regarded as a bunch of pictures and words. When some teachers do PPT, they are used to thinking about where to do it, and there is no good logical plan, which makes it difficult for students to understand.
Tip: Increase navigation and enhance students' memory.
First of all, the teacher needs to sort out the logic of a class's teaching content and draw up the outline of PPT content. When making PPT, you can add navigation to show the structure of the whole courseware, such as:
Catalogue: A simple and clear catalogue can present a clear context of the courseware, so that students can see at a glance and easily grasp the main contents;
Title bar: In addition to the title of the whole PPT, each page should be marked with the title of this chapter and the theme of this page.
Page number: add as much as possible if it is convenient.
Myth 3: The page is too fancy.
Some teachers will add some fancy elements unrelated to teaching to attract students' attention.
Note that some irrelevant contents in the courseware will distract students' attention, disturb their thinking and weaken the effect of classroom teaching!
Tips: The typesetting is neat and the PPT style is unified.
1, the overall template and tone should be unified.
There is no special need, generally do not change the tone or style of the background setting. If you want to have a sense of layering, you can use different gradients of the same background color to maintain color harmony;
2, fonts can be unified as much as possible.
If there are more than three fonts on a page, it will be a bit messy. Try to control the font in 1-2;
3. The selected materials are related to the teaching content.
Nowadays, the network resources are very rich, and teachers can choose a variety of materials when making courseware. But these materials must be related to the teaching theme, otherwise there will be two consequences: first, the courseware looks messy, and second, it will distract students' attention;
4. Don't use complicated action settings and animation schemes.
When switching pages, we should be careful with fancy movements and irrelevant sounds, especially when students need to think about problems, and suddenly switching sounds unrelated to the teaching content will easily disturb students' thinking and distract them. You can add some effects to the discussion of lighter topics, but it should not be more than two.
Myth 4: Do not test after PPT.
Some teachers think that after completing PPT, there is actually the most important step-on-site testing. If you miss this step, all your previous efforts will probably be in vain ~ ~
Tips: On-site test to ensure the classroom effect.
Check whether the versions are compatible. There are several versions of PPT software. After making it on your own computer, you have to record the on-site test, so that you can know whether the versions are compatible and ensure the normal demonstration.
Check the correctness of hyperlinks and action effects in PPT. Some courseware has many hyperlinks and action effects. If you don't carry out on-site testing, you may expose various problems when using it in formal occasions, such as dead chain or improper action effect, and it will be too late to modify it.
Compare the effect of computer and big screen. The effect on the computer is different from the visual and auditory effect displayed by the projector. Especially when there are many colors contrasting, overlapping and crossing, it often looks good on the computer, but students can't see the contrast effect of words and colors clearly on the big screen. At this time, field testing is particularly important.
