PowerPoint is the most common presentation design tools, because it the function of multimedia powerful and easy to operate, so many teachers with PowerPoint, for tools produce courseware. PowerPoint built-in rich animation, transition effects and various sound effects, and have strong hyperlink function, can be directly call external many files, and can satisfy the general teaching requirements.
Many teachers making courseware PPT there are some errors, such as demo contents of papers not clear, the levels of the structure in the slide to join many and the content of the course of the graphics and animation, has chosen not the right template and colour collocation and so on, so that many students at first think multimedia teaching is flowery, but soon lost interest, to yearn for the previous "the blackboard".
The author thinks that, courseware PPT has the characteristics of its own, and in the courseware and teaching, teachers should grasp several principles.
The structure of the courseware to clear
In the blackboard era, a section 45 minutes of curriculum, teacher's version of the book is generally two to 3 edition. And the same time PPT to use 10-slides 25 zhang, PPT make the class of information greatly enriched. But following a problem is, if there is no clear hierarchy, huge information will get students head spin, and record class notes is very difficult also.
To do structure is clear, the text to refine first courseware, the large character elaborates on teaching material does not have to be in the courseware the repetition, even to occur, also try to enrichment, in plain, scouring the text summarized the main points. Secondly, in the courseware can be repeated directory page, each finished a big problem, and repeat playlist pages, make the students also distracted can overtake course train of thought; There is the whole course project symbols and Numbers to unity, and try to keep consistent with teaching materials for students to take notes.
Prominent course content. Don't use of multimedia material and independent of the animation
Many teachers produce courseware, like to collect pictures in hand, animation and sound, no matter any relationship with the content of the course, isn't it help students understand and master knowledge, all in the stack courseware, even some "winning" courseware also is such.
Courseware for teaching service is, after all, too much, too fancy multimedia material instead will distract the attention of students. The author in the explanation of the E-mail transfer principle, who specially made contrast test, two level almost class, A class of courseware that part of use is A simple and unadorned simple picture example, B class is using A "wonderful" flash animation. After the end of the class along with hall test showed that A class of this part of the student's knowledge of good in B class. To student's interview also shows that many of the class B students only remember the flash of the cartoon characters and visual effect, but the really important knowledge but no attention too much.
In photography, the composition of the basic principles of the "negative", that is, as far as possible the theme from the elements in the picture has nothing to do less. Courseware can use this principle, use first "addition" the collected at ordinary times, with the teaching contents related material in PPT, and then do it again "negative" send repeated and correlation is not big material guarantees.
In the process of teaching attention grasp rhythm, hold the attention of students
Text the word in the slide leaflet to 30, 60 Chinese characters as appropriate, speak time to 3-5 minutes advisable, if a question or the content of the concepts more, slide it can not put down due to two tickets, avoid by all means is forced the text in a slide accumulation.
The research of psychology shows that students' attention span is around 15-25 minutes between, experienced teachers in found that students who the distraction of time, usually will insert a "baggage", get the students to focus the attention of the scattered to class. In making courseware PPT to conscious in the student easily distracted time periods, insert a animation, such as sound or can cause the attention of students material.
Templates and colour collocation
And the web design, PPT also taboo "colorful", too much color can appear mixed and disorderly, and scattered the attention of students. Generally speaking, in addition to the black and white, the most tie-in 3 colors. Suggested that each courseware ready to two kinds of colour collocation to adapt to different environment light. The first kind of blue BaiYu, suitable for environmental light to compare under the condition of strong use, this kind of colour collocation can let students see text, and not easy to generate visual fatigue. The second kind of a white background with black text, suitable for darker environment to use, because the white DeBan let students can see teacher "body language".
PowerPoint own dozens of template may have used all vexed, you can go to the BBS download some new template.
Teaching is the student as the main body, the roles of teachers a process, any type of multimedia courseware in this process is just a assistant method. The teacher can make PPT class key to highlight the difficulties, scattered, and it is difficult to use language description of the principle and process using multimedia material image, intuitive to demo it out. But courseware is not a class of all, the whole course is still to roles of teachers, so, we don't have to do the courseware matter, not by the students should be more thought so easily show come out, what we have to do is through the courseware show to arouse students' interest in study actively, promote the students' active explore and think, promote the students' creative learning .
