| 概要 |
Due to the recent progress of ICT, computer science education for kids has received great attention. However, such attempts focus on computational science, such as programming, but not on informationa...l science, which includes how to express information, like digitization. With the motivation to teach informational science to kids, the author has already developed workshops and classes about the Fourier transform and the sampling theorem. These notions are subjects taught at universities, and they are too difficult for kids to understand. But they could be fascinating educational materials for kids since they are closely related to many physical phenomena, such as rainbows. Although many kids enjoyed the workshop the author developed, we had to exclude kids in early elementary school grades from our workshops because we had to assume that kids had already learned average in mathematics. In the past workshops, we explained the Sampling theorem after the Fourier transform, which requires the notion of average. Instead, without using the Fourier transform, we just only treat the Sampling theorem, which shows the minimal frequency of digitization to reconstruct a continuous function, like sound waves. To make learning the theorem fun for kids, we adopt an approach like a puzzle-solving game, where the kids first see a strange phenomenon related to the theorem and try to discover its mechanism using many hands-on materials, such as flipbooks and a Web app. In this paper, we show the approach and materials developed by the author for two workshops.続きを見る
