Web-based technology has a dramatic impact on learning and teaching. A framework that delineates the relationships between learner control and learning effectiveness is absent. This study aims to fill this void. Our work focuses on the effectiveness of a technology-mediated virtual learning environment (TVLE) in the context of basic information technology(More)
In recent years, Web applications have grown rapidly As Web applications become complex, there is a growing concern about their quality and reliability. In this paper, we present a methodology that uses an Object-Oriented Web Est Model (WTM) to support Web application testing. The test model captures both structural and behavioral test artifacts of Web(More)
Recently, the extraordinary growth in the World Wide Web has been sweeping through business and industry. Many companies have developed or integrated their mission-critical applications using Web technologies. As Web applications become complex, testing Web applications becomes crucial. This paper extends traditional data flow testing techniques to Web(More)
Multicast routing is an effective way to communicate among multiple hosts in a network. It outperforms the basic broadcast strategy by sharing resources along general links, while sending information to a set of predefined multiple destinations concurrently. However, it is vulnerable to component failure in ad hoc network due to the lack of redundancy,(More)
Abstract: During recent years, optimal electrification of isolated offshore systems has become increasingly important and received extensive attention from the maritime industry. Especially with the introduction of electric propulsion, which has led to a total electrification of shipboard power systems known as all-electric ships (AESs), the need for more(More)
A framework that delineates the relationships between learner control and learning effectiveness is absent. This study aims to fill this void. Unlike previous research, this study compares the learning effectiveness between two learning environments: traditional classroom and Technology-mediated Virtual Learning Environment (TVLE). Our work focuses on the(More)
