Physical Education in elementary schools needs higher-level materials than other subjects. Most PE teachers are also the instructors and the demonstrater. The students can learn through the teacher\'s motions and their methods. Nowadays most of the teachers in elementary schools are women and they used to avoid tPE class because of their lack of professional ability. These teachers want to have more useful materials for teaching and learning. Especially, it is important that they are not complicated and difficult to use it. So I produced the useful WBI material for rope-skipping. Nowadays the development of the Internet and multimedia brings very great learning effect to the field of education. The WBI materials with the Internet provide much multimedia data, so it can be called a flower of the learning and teaching materials. However, the existing Web materials for rope-skipping are not useful for elementary school students. They have many difficulties ; eg. becoming a member, a fee-charging site. So, it is hard to use for learning and teaching. In addition, the floating materials on the Web are just like a flood and so we have difficulties choosing right information. Therefore, I developed the WBI rope-skipping courseware so that every user can apply without problems.
