In this article, we describe the development of a mobile butterfly-watching learning (BWL) system to realize outdoor independent learning for mobile learners. The mobile butterfly-watching learning system was designed in a wireless mobile ad-hoc learning environment. This is first result to provide a cognitive tool with supporting the independent…

A major determinant of the success of educational intranet sites is their usability. In addition to measures of task performance and navigation behavior, psychometric instruments are used to evaluate usability and the quality of human-computer interaction more generally. However, there is a lack of validated instruments for the evaluation of…

Powers, Burstein, Chodorow, Fowles, and Kukich (2002) suggested that automated essay scoring (AES) may benefit from the use of "general" scoring models designed to score essays irrespective of the prompt for which an essay was written. They reasoned that such models may enhance score credibility by signifying that an AES system measures the same…

In this article, we present a study focused on developing students' understanding of the ecology through participation in a technology-supported urban planning simulation--specifically, 11 high school students in Madison, Wisconsin acted as urban planners to redesign a local shopping street using a Geographic Information System (GIS) model. This…

Having students express their understanding of difficult, new material in their own words is an effective method to deepen their comprehension and learning. Summary Street[R] is a computer tutor that offers a supportive context for students to practice this activity by means of summary writing, guiding them through successive cycles of revising…

PDAs (Personal Digital Assistants) have been used widely in educational settings. In this study, the visual illustration of a scientific text (cognitive-interest illustration, emotional-interest illustration, or no illustration) was manipulated to investigate its impact on student interest in instructional materials, achievement, and time spent on…

In this study, the relevance of the distinction between sequential and global learners in the context of learning with hypertext was investigated. Learners with global learning style were expected to produce better results when learning with hypertext, whereas learners with sequential learning style should profit from a structural aid in form of a…

Increasingly, technology skills are becoming central to academic and economic success. More and more technological tools are becoming a vehicle for teaching and learning and a vehicle for buying and selling goods. However, research continues to show that women lag behind men in PC-ownership regardless of social economic status (SES) or education…

With the expansion of Internet-based instruction, research-based guidelines are needed to support faculty decision making during course design to ensure student success and satisfaction with instruction incorporating new delivery technologies. This investigation consisted of two phases. In Phase One, computer skills and attitudes toward…

In a series of 5 experiments in 2000 and 2001, several hundred students at two different universities with three different professors and six different teaching assistants took a semester long course on causal and statistical reasoning in either traditional lecture/recitation or online/recitation format. In this article we compare the pre-post…

The purpose of this study was to compare the relative effectiveness of live (SERT) and computer-based (iSTART) reading strategy training. Prior to and after training, participants read scientific texts and self-explained after each sentence. They also answered comprehension questions. Students showed improvement in the quality of their…

Users of educational hypertext are faced with the challenge of creating meaning both within and between texts. Cohesion is an important factor contributing to whether a reader is able to capture meaning and comprehend text. When readers are required to fill in conceptual gaps in text, comprehension can fail if they do not have sufficient…

This analysis of gender performance differences in a first-level New Zealand university course in computer science is predicated on the model of academic ability proposed by Charles Spearman, the eminent educational psychologist and statistician. The regression model is based on the theoretical constructs of general academic ability and specific…

Arguing against the common perception of technology as passive, neutral, and universal, this article presents a theoretical analysis of a commonly used and frequently studied technology--Computer Mediated Communication (CMC)--to illustrate how a technology that is often undistinguished in practice and research is indeed active, biased, and…

This study investigated strategies teachers can use to improve students' use of self-regulated learning strategies in a Web-based setting. SRL is defined as a learner's intentional efforts to manage and direct complex learning activities and is composed of three primary components including cognitive strategy use, metacognitive processing, and…
