The purpose of this study is to examine the effects of a physical education lesson performed by using digital teaching materials and digital portfolios in an elementary school. This study discussed a lesson of vaulting box exercise which took place 8 hours in November, 2005. The subjects were 37 fourth graders and were taught by one male teacher with 13-year teaching experience. In this lesson, the digital teaching materials developed in advance were applied in order that they could be used at any time according to each child's skill. Moreover, digital portfolios were utilized in order that children could do both self and mutual evaluation of his/her improvement of the learning subject and motor skills. Their skill levels, their perceived motor competence score, the actual state of using the digital teaching materials and children's feelings of effectiveness of using them were measured before and after the unit. And, their formative evaluation scores and their feelings of effectiveness of using the digital portfolios were measured during the unit. The results were as follows:
1. The motor skills of all the children improved notably: they came to be able to perform forward roll on the vaulting box with three or more stairs after the unit.
2. The children's formative evaluation scores were highly maintained through the unit.
3. The actual state of using the digital teaching materials and the changing process of effectiveness of using them through the unit became clear.
4. The feelings of effectiveness of using the digital portfolios improved significantly after the unit.
5. The perceived motor competence scores improved significantly after the unit.
