How To Get A Create A Stunning Educational Slide-Lecture Now. Very often, when preparing for a Stunning Educational Slide-Lecture, teachers use slide-notes (presentations) as illustrative material. Based on this, one of the options for an educational resource can be a slide lecture, the educational material of which can be represented as:
Stunning Educational Slide-Lecture
- Graphics (photos, drawings, diagrams, etc.);
- Managed and unmanaged animation (two-, three-dimensional);
- Video and audio data.
The advantages of using slide lectures include:
- An ability to integrate various graphics and multimedia components of the presentation of educational content;
- A possibility of an extensive illustration of the lecture;
- An ability to flexibly manage the content of the slide lecture, which is ensured by quick access to the necessary information block at the moment;
- Arbitrary variation in the rate of a study of educational material;
- Prompt return to previously viewed material;
- An ability to illustrate the dynamics of some processes through the step-by-step demonstration of the informative block of the slide.
However, it should not be forgotten that the technology of using Lecture does not eliminate a lecturer from the educational process. It complements him. The main task of a lecturer is commenting on the content of slides, adjusting the pace of the lecture, changing the slides or the appearance of information blocks of the slide, as well as verbally adding some information to blocks shown on the slide if necessary.
There are a lot of free presentation tools on the Internet, but one should remember that if a slide lecture is unique and was made by the lecturer for a specific group, it would be of more interest and student engagement is likely to be higher. It is more complicated to create a perfect presentation that would be more useful and interesting for students than just search on the Internet for “do my essay cheap” or “ready-made presentations”, but the students learning outcome will be amazing.
The development of a slide design is the formation of color characteristics of visual information visualized on a computer screen or a projection screen while working with a slide lecture.
An important role in the organization of visual information is played by the contrast of objects concerning the background. There are two types of contrast: direct and reverse. In direct contrast, objects and their images are darker, and in reverse, they are lighter than the background. In the slide lecture, it is advisable to use the reverse contrast.
According to the psychology of perception, numbers, letters, and signs, presented in reverse contrast, are identified more accurately and faster even with smaller sizes.
The most commonly used techniques for creating logical stresses are:
- Image of the main object in a brighter color;
- Changing the size, brightness, location of the object;
- Object highlighting by flashing light.
The aesthetic-ergonomic indicators of the slide-lecture and the comfort of perception of visual information are significantly influenced by the degree of contamination of the field of the main object. It is recommended to place no more than 4–6 minor objects in the field of the main object. An increase in the number of secondary objects can lead to the dispersion of attention and, as a result, to the loss of the main object from the area of attention or to the merging of secondary objects with the background.
Particular attention should be paid to the use of illustrations. The use of one or another type of illustrations should be done in places that are difficult to understand, requiring additional clear explanations, as well as for generalizing and systematizing thematic, semantic blocks, for a general revitalization of all educational material.
A specific number of illustrations for a separate screen or the entire slide lecture is not specifically installed. It is necessary to determine this parameter individually in each specific case, taking into account:
- Content and nature of educational material;
- Selected teaching methods;
- Possibilities and specifics of education level and forms.
The informative part of a presentation should contain short words and sentences, to minimize the number of prepositions, adverbs, adjectives. Punctuation is not recommended to use as well even when slides contain “complete sentences”.
The title of the slide should attract attention, but at the same time, it should not distract students from the main information component of the slide. This is achieved by highlighting the title of a slide from the main text in a larger font (the difference should be at least 8 points) and using different colors for the text and title.
The text of a slide must be placed horizontally, the most important information should be placed in the center, which allows focusing the audience’s attention on the key points.
When filling a slide with information, it should be remembered that a person can simultaneously remember no more than 7-9 objects. Also, when forming the content of a slide, one should be guided by the following principle: the number of elements is inversely proportional to the semantic load of the slide. Therefore, areas that are not filled with any information are an important part of the slide, facilitating its perception. A properly prepared slide has wide gaps between the lines and spacious fields. Too much text or pictures will only worsen the student’s perception of information. Long lines get student’s eyes tired. It is better when a line is no more than 7–10 words.
The main rule – graphics, images, photographs, and animation is preferable to a text, but at the same time, illustrative materials should always refer to the text of the lecture.
A stunning slide-lecture will allow students to:
- better remember the needed material;
- diversify the lecture material;
- show video snippets.
Nowadays, no lecturer can deliver lectures without any handy visual material. Thus, the trend to create presentations is becoming more and more popular and should be mastered by every teacher to improve their performance.
