Due to the increasing use of very large databases and data warehouses, mining useful information and helpful knowledge from transactions is evolving into an important research area. In the past, researchers usually assumed databases were static to simplify data-mining problems. Thus, most of the classic algorithms proposed focused on batch mining, and did(More)
Evaluation of CAL systems Improving classroom teaching Interactive learning environments Media in education a b s t r a c t Previous studies have pointed out that computer games could improve students' motivation to learn, but these studies have mostly targeted teachers or students in elementary and secondary education and are without user adoption models.(More)
Human flesh search (HFS), a phenomenon that has recently emerged over the Internet, represents the interaction between the virtual and real worlds. The term "HFS" is equivalent to "cyber manhunt" in the West, although there were more large-scale HFS events reported in the East recently. While the majority of academic articles on HFS have focused on the(More)

Web design guidelines are adopted by many usability evaluation methods as one of the criteria for success, while usability is proven to significantly impact Website performance. Since Web design guidelines cover a broad range of system and interface design solutions, knowledge of them can be considered as a prominent indicator of Web design skills for(More)
Keywords: Instant messaging Task-oriented communication Simplex and complex communication Emotional effects Emoticons a b s t r a c t Many studies have shed light on general computer-mediated communication, instant messaging (IM), and emotion or emoticons, but little is known specifically about the impacts of emoticons in task-oriented IM communication in(More)
Simulation beginners often spend a great amount of time to accumulate the knowledge as well as the experience to overcome the technical complexity of computer simulation. Limited by time availability, classroom instructions usually contain little simulation statistical analysis after many hours of simulation modeling and programming. However, the success of(More)
The popularity of distance education has grown rapidly over the last decade in Taiwan's higher education, yet many fundamental teaching–learning issues are still in debate. While teacher–student interaction is a key success factor in distance education, little work has been done on the teachers. The intent of this research was to clarify teacher's(More)
