Acta Medica Okayama 2014 Learning computer science by watching video games 134 135 EN Hiroyuki Nagataki This paper proposes a teaching method that utilizes video games in computer science education. The primary characteristic of this approach is that it utilizes video games as observational materials. The underlying idea is that by observing the computational behavior of a wide variety of video games, learners will easily grasp the fundamental architecture, theory, and technology of computers. The results of a case study conducted indicate that the method enhances the motivation of students for deeper learning of computer science concepts.

Acta Medica Okayama 2007 A Fault Injection Method for Generating Error-correction Exercises in Algorithm Learning 200 205 EN Ryota Itoh Hiroyuki Nagataki Fukuhito Ooshita Hirotsugu Kakugawa Toshimitsu Masuzawa In this paper we propose a method for generating errorcorrection exercises for undergraduate students in computer science who learn algorithms. Our main goal is to inject faults automatically into a correct source code that implements an algorithm to be studied. The proposed method utilizes design paradigm of the algorithm to determine effective fault types and positions in a source code.<br> We have developed a prototype system and evaluated the appropriateness of the generated exercises to algorithm study. We carried out error-correction exercises in an algorithm class, and most students evaluated that the exercises are effective for algorithm study.

SciTePress Acta Medica Okayama 1 2011 A DISTANCE LEARNING SYSTEM WITH CUSTOMIZABLE SCREEN LAYOUTS FOR MULTIPLE LEARNING SITUATIONS 94 102 EN Hiroyuki Nagataki Koji Noguchi Ryo Katsuma Yukiko Yamauchi Naoki Shibata Keiichi Yasumoto Minoru Ito In this paper, we propose a new distance learning system that can adapt to various styles of learning activity. We assume that the system is used in distance classes with multiple live-streaming videos. Our system has functions to change the screen layout to best suit for the current learning situation for each of the participants in a class. The system also has a function to efficiently monitor the behavior of many students at a time. These functions enable us to adapt various learning activities in distance learning classes. We implemented a prototype of the proposed system and evaluated it in experimental classes. We confirmed that our system improved the activities in the experimental classes.

IEEE Acta Medica Okayama 2 2010 A kinesthetic-based collaborative learning system for distributed algorithms 97 101 EN Hiroyuki Nagataki Taichi Fujii Yukiko Yamauchi Hirotsugu Kakugawa Toshimitsu Masuzawa In this paper, we present a learning support system DASE-E to help students understand fundamental concepts of distributed algorithms in computer science. DASE-E is a collaborative learning system, in which the task of students is to devise a distributed algorithm. DASE-E offers a set of small wireless terminals with accelerometers. Each student plays the role of a process with a terminal, according to the algorithm that students devised. Each terminal enables a student to take physical actions that control the behavior of a process in the simulator. After the role playing simulation is finished, students discuss their activity played back on a screen. We implemented the system for learning distributed leader election algorithms, had a trial exercise in our research group, and we confirmed that it is effective to learn the critical part of distributed systems and algorithms.
