RECOMMENDATIONS FOR PRESENTATIONS
Electronic presentation - an electronic document, which is a set slides designed to demonstrate the work done. Presentation purpose is a visual representation of the author’s intention, the most convenient for perception. 
An electronic presentation should show something that is difficult to explain in words.
Presentation Scheme:
1. title slide (corresponds to the title page of the work);
2. goals and objectives of the work;
3. the general part;
4. the main part;
5. conclusions.
Slide Design Requirements
Title slide
The presentation begins with a slide containing the title of the work (report) and the name of the author. These elements are usually shown in a larger font than the body of the presentation. As the background of the first slide, you can use a picture or photo that has directly related to the topic of presentation, however, text on top of such an image should be read very easily. A similar rule is observed for the background of the remaining slides. However, a monotonous background or a background in the form of a soft gradient looks on the first slide also quite spectacular.
General requirements
The average calculation of the time required for the presentation is based on the number slides. 
Usually, one slide takes no more than two to three minutes. 
It is necessary to use the maximum screen space (slide) - for example, stretching the drawings. 
Design should be simple and concise. 
Each slide must have a title. 
The design of the slide should not distract the attention of listeners from its content. 
The presentation should be completed with a brief summary containing its main points, important data presented in the report, etc.
Header Design
The purpose of the title is to clearly inform the audience about the contents of the slide. 
The title should indicate the main idea of ​​the slide.
All headers should be in the same style (color, font, size,tracing).
Heading text should be 24 to 36 points.
Font selection
To design a presentation, you should use standard, widely common fonts such as Arial, Tahoma, Verdana, Times New Roman, Calibri, etc.
The font size for the information text is 18-22 points. Font less than 16 points poorly readable when projected onto the screen, but an excessively large font size makes it difficult fluent reading process. When creating a slide, keep in mind that sharpness images on the big screen are usually lower than on the monitor. Uppercase are perceived harder than lowercase. Bold, italics and capital letters use only for highlighting.

The topic selection is carried out by student number in the group list, which is located on the main page of the distance learning portal in the section Student - Student Lists

After creating and making a presentation, you need to rehearse its presentation and your performance. Check how the presentation as a whole will look (on the screen computer or projection screen) and how long will it take to display it.

The topic of the abstract is selected according to the student number in the group list, which is located on the main page of the distance learning portal in the section Student - Student Lists
