A wave of good courseware - courseware \

Mechanical Vibration and mechanical wave, \It is a positive piece of courseware, ten large and small, concentrated product parts, basically covers the mechanical vibration and mechanical waves in the teaching of all the necessary content, has great generality. Regardless of which version of the textbook, and regardless of which region of the teachers, as long as able to use this part of teaching. This piece courseware product features, the reach of the general courseware. The courseware is not only in the layout,[link widoczny dla zalogowanych], color, structure and transitions such as the design of a generous, crisp, concise and easy to operate, it is more important is that it leverages Flash's interactive features, is difficult to sort out the physical relationship between the handled just right. As two examples of simple harmonic motion - pendulum and spring oscillator, we can demonstrate to the students to find its rule, it is difficult to make clear such as \relations, and courseware to shift the size of the physical display rapidly changing direction was clear. Teachers in both full presentation, you can also step analysis, or dynamic or static, or single or double, all the teachers decision. Vibration of the whole image and waveform image of two tough one chapter, the same mathematical form and woven into different physical nature of the difficulties of teaching. Around these two images need to say a lot of things,[link widoczny dla zalogowanych], we found that of the very smart, he does not like the same courseware as the children talk about the whole thing will fall into moving, but to seize the only performance with multimedia tools to be the most critical points prominent, for those who can use conventional means to resolve the content is left to the teachers themselves to resolve. For example, the image vibration, of seizing only the \this simple picture, however, when you change the shift speed or vibration cycle, but it can accurately draw images of different vibration t Similarly, the waveform image, caught the wave of the definition of the main points: Dissemination is the wave of the \into a more eye-catching yellow) of the displacement,[link widoczny dla zalogowanych], two different waves of displacement is the most vivid interpretation of the concept. Wave interference and diffraction of waves have a wonderful design of the pen. Wave diffraction contrast technique using diffraction phenomenon highlights the conditions, the effect is very clear t change the distance between two coherent wave sources,[link widoczny dla zalogowanych], the strength of interference fringes are changed, rare in the general courseware, the design has certain degree of difficulty. We note that those who can change the parameters to control the physical phenomenon where the use of this technique as much as possible, which greatly enhanced the interactive features of courseware for teachers to organize students to independently explore provides excellent conditions. Teaching wave interference has three levels: the phenomenon of wave interference,[link widoczny dla zalogowanych], wave superposition and wave interference pattern analysis. Arranged in the courseware of the third and give up the first two. In fact, the first two levels of hand, the use of conventional means of teaching the most obvious or powerless, and thus most in need of a dynamic description of the third level will only need a static image can be, say that this is a pity. Can be seen in the courseware design, to create what is, not making anything, are the first issues to consider.
