The popularity of computer games has grown enormously in recent year. Many studies and systems that incorporate the inherent elements such as "pleasure" and "fun" in the game to improve a learner's motivation have been developed in the field of learning environments. However, there are still few studies of situations where many learners gather at a single(More)
Many studies and systems that incorporate elements such as “pleasure” and “fun” in the game to improve a learner’s motivation have been developed in the field of learning environments. However, few are the studies of situations where many learners gather at a single computer and participate in a game-based learning environment (GBLE), and where the GBLE(More)
The aim of this study is to design and develop an interaction model to perform the collaborative teaching process among pedagogical agents. A pedagogical agent has a role in a situation of the teaching process. However, the role is not fixed, but dynamically changed according to the learner's understanding. So, in this paper, we have analyzed the(More)
The competency and curriculum for human resource development in knowledge based society are proposed in each country. We think the keywords are “collaborative problem solving” and “effective use of ICT”. In particular, the competency to perform the collaborative problem solving and learning with others on the network is requested in next generation. We have(More)
The aim of this research tries to design a learning support model that includes a teacher who gives a lesson in a school and distance teaching assistants (Distance TAs) who asynchronously support group learners, who are engaged in problem-solving activities in a learning support environment and develop Distance TA’s learning support methods and some tools(More)
We analyzed the effect of high hydrostatic pressure (HHP) treatment on reducing sugar production in the tuberous root of sweet potato (Ipomoea batatas), based on pressure-gelatinization of starch and subsequent saccharification by internal amylases. HHP treatment at up to 600MPa at ambient temperature for 10min did not apparently affect the reducing sugar(More)
The authors have developed the Internet browser application Gymn@zilla for L2-learning. In this paper they present a dynamical image annotation: Gymn@zilla automatically provides explanatory images drawn from Internet for words in L2. The Internet-images are often photos of daily events. The authors discuss the psycholinguistic implications of images in L2(More)
