Knowledge of science
A critical word in advance: As early as the year 2004, a study group at the University of New South Wales (Australia) came to the conclusion that we are overpowering our slide presentations.
It is counterproductive to convey information in a mixture of acoustic, visual and possibly even moving forms. Information would be better understood if delivered either acoustically or visually.
Why overwhelm us with presentations?
The reason: When text and language run in parallel, the writing dominates. The spoken word fades away and is forgotten.
But: films are not bad per se; because they meet the habits of man: man is an eye-catcher and takes visual information particularly efficiently.
But what does the reality look like? Slide presentations are often of miserable quality. It still seems to hold the prejudice that the number of slides and information correlates with the competence of the presenter.
In addition, most slide presentations are filled with far too much text and details. But the opposite is true, both in terms of the amount of slides and their content: less is more.
Step 5: Compress your collection of materials to theses
Now proceed to assign the collected material to the individual outline points. With regard to the number of slides there are quite contradictory recommendations in theory and practice. Basically, "When in doubt, cut it out!"
If you have doubts about whether a slide is needed, then remember: "In really good presentations, something is shown that could not be better presented verbally." So the question of goodness is this: does a slide make the audience understand and contribute to it? to convey my content faster / better?
Frequently quoted is the 10-20-30 rule by Guy Kawasaki; it means that a slide presentation does not include more than 10 slides, should take minutes under 20, and should have a font size of at least 30 point.
Step 6: visualize your theses
Avoid all that eats reading energy, such as logos, small pictures, legends, ornaments, shadows, boxes, footers, and the like. Even my headings are not necessary in my opinion - you are finally present and explain what is to be seen.
Slides should be like traffic signs: Quick and easy to understand. So, separate yourself from everything that is not absolutely necessary.
Differences are important!
Forgo a "master": human perception usually processes every image completely new. If, however, large parts always look the same, the brain concludes "I already know" and shuts off.
Design your slides differently. Only the first and last slide should appear in the "corporate identity dress" (fonts, colors, logo), in between, variety is needed.
Contrasts and harmonious colors
Choose a white / light or dark background. You can also choose a signal color (light green, orange) - the contrast is clear, so the writing or picture elements are easy to recognize.
Use colors that harmonize with each other - these are the colors that are in the color circle, such as orange and blue or green and red.
Less is more!
Never write more than 40 words on a slide. Typically, you will get less than 20 words. Some experts say: the contents of a film should be captured in less than two seconds.
Use a large font, at least 24, better still 30 point. This not only promotes legibility, but also limits the space available to you - so you are automatically forced to self-imposed. Also, use a large line spacing.
Pictures and graphics
Never use more than 7 pieces of information (lines / text blocks, images, graphics, symbols ...) because working memory capacity is limited to 7 (+/- 2) elements.
Include full-page pictures (photos) without labeling in the lecture. The picture should build up tension and work for you - you will provide the explanation with your presentation. If you do not use full-page images, only small cut-outs, arrange the image elements asymmetrically, ie not centered.
Step 7: Hold a trial and correct your slides
The more important your presentation is, the more time you should invest to practice and improve it. Ask your colleagues, friends or friends for their judgment. Try to keep your speech clear.
If you do not succeed in doing so, then make yourself a speech, but without formulated sentences, otherwise there is a risk that your presentation sounds too "wooden" or monotonous. Finally, check that your presentation is error-free in terms of content and dramaturgy, spelling and punctuation, and form and readability.
