Some basic principles of PPT Courseware making

PowerPoint is the most commonly used demo design tool at the moment, because it is powerful and easy to learn, so many teachers use PowerPoint to make courseware for tools. PowerPoint has a rich animation, transition effects and a variety of sound effects, and has a powerful hyperlink function, you can directly call the many external files, to meet the general teaching requirements.
Many teachers make PPT courseware when there are some misunderstandings, for example, the content structure of the presentation is not clear, the slides include many pictures and animations that are not related to the course content, the selection of inappropriate templates and color collocation, and so on, so many students at first thought that multimedia teaching is very fancy, but soon lost interest, began to miss the previous "blackboard."
The author thinks that PPT courseware has its own characteristics, in the course of making and teaching of courseware, teachers should grasp several principles tightly.
The structure of the courseware should be clear
in the Blackboard era, a 45-minute course, the teacher's version of the book is generally two to three editions. And the same time PPT slides to use 10-25, PPT so that the amount of information in the classroom is greatly enriched. But one of the problems with this is that without a clear hierarchy, huge amounts of information can make students disoriented, and it's difficult to record class notes.
to achieve a clear structure, first of all, the text in the courseware to be concise, teaching materials on the large section of the text is not repeated in the courseware, even if to appear, but also as far as possible to concentrate, to the plain, concise text summed up the main points. Second, in the courseware can repeatedly duplicate the table of Contents page, every time I finish a big question, I repeat the table of contents, so that the distracted students can catch up with the idea of the course, as well as the whole course of the project symbols and numbering should be unified, and as far as possible with the teaching materials to be consistent to facilitate the students to take notes. The
highlights the course content. Do not use irrelevant multimedia material and animation
Many teachers make courseware, like the collection of pictures, animation, sound, regardless of the course content has no relationship, is not conducive to students to understand and grasp knowledge, all piled up in the courseware, even some "award" courseware is also so.
Courseware is after all a service for the teaching, too much, too fancy multimedia material will distract students ' attention. The author in explaining the transmission principle of e-mail, has done a comparative test, two levels of the same class, Class A courseware in this part of the content is a simple plain picture example, Class B uses a "wonderful" flash animation. After the class, the test showed that class A students had better knowledge of this part than Class B. Interviews with students also show that many students in Class B only remember the cartoon characters and visual effects in Flash, while the really important knowledge did not pay attention to too much.
in photographic work, the basic principle of composition is "subtraction", that is, to minimize the elements irrelevant to the subject from the screen. CoursewareThe production can draw on this principle, first with "addition" to the usual collection, and teaching content has related materials into the PPT, and then do "subtraction" to the repetition and the relevance of the material to exclude.
Pay attention to the rhythm in the course of teaching, grasp the students ' attention tightly
the words in the single slide are 30-60 Chinese characters, the time is 3-5 minutes, if a problem or concept of more content, a slide can not be divided into two pieces, Don't force the text to accumulate on a single slide.
Psychological research shows that students ' concentration of time is about 15-25 minutes, and experienced teachers tend to insert a "burden" when they find students are distracted, concentrating their distracted attention on the classroom. In the production of PPT courseware, it is necessary to be conscious of the time when the students are easily distracted, inserting a animation, sound or other materials that can cause students ' attention.
Templates and Colors
and the design of the Web page, ppt also taboo "colorful", too many colors will appear messy, and distract students ' attention. Generally speaking, in addition to black and white, with a maximum of 3 colors. It is recommended that each courseware be prepared with two color combinations to suit different ambient light. The first kind of blue bottom Baiyu, suitable in the environment light relatively strong circumstance use, this kind of color collocation not only can let the student see the text, but also not easy to produce the visual fatigue. The second white background black word, suitable for use in the darker environment, because the white bottom slab so that students can see the teacher's "body language."
PowerPoint Dozens of templates that come with you may already be annoying, you can download some new templates to the forum.
Teaching is a student-centered, teacher-led process, any type of multimedia courseware in this process is only an auxiliary means. PPT enables teachers to focus on a class, difficult to disperse, the difficult to use language description of the principle and process with multimedia material image, intuitive demonstration. But the courseware is not the whole of a class, the whole course still take the teacher as the leading, therefore, we do not have to do all the courseware, not to the students should be thinking about the problem so easily displayed, we have to do is through the display of courseware to stimulate students to actively study the interest, to promote students ' active exploration and thinking, Encourage students to learn creatively.
