The WebQuest as an instructional tool has recently been widely adopted in K-16 education. However, its underlying principles and functionality are not well understood, which has resulted in an inconsistency in practice. This study identifies the underlying constructs of WebQuests as perceived by teachers and variables affecting their perceptions on WebQuests. A survey was conducted on teachers (n = 226) recruited from one large research university in the USA and a professional listserv. The findings reveal three constructs perceived by teachers as critical to WebQuests: constructivist problem solving, social interaction and scaffolded learning. Results also show that variables like purpose of WebQuest use, years of teaching, years of WebQuest use and gender predict, at various degrees, teachers' perceptions on WebQuests. Discussions are made on how the constructs identified can be used to improve online teaching and learning. Suggestions for future study are included by examining the influences of social, psychological and affective factors on learners' learning in WebQuests.

The present study investigated (1) the impact of cognitive styles on learner performance in well-structured and ill-structured learning, and (2) scaffolding as a cognitive tool to improve learners' cognitive abilities, especially field dependent (FD) learners' ability to thrive in an ill-structured learning environment. Two experiments were conducted with 116 college students recruited from a large research I university in the west of the United States. Experiment 1 (n = 42) employed the group learning strategy to match learners' cognitive styles in asynchronous online learning. The results showed that the style matching strategy failed to yield expected gains in ill-structured asynchronous learning for FD learners. Different from the style-matching strategy, experiment 2 (n = 74) used a scaffolding model proposed by Cazden (1988) to improve FD learners' cognitive abilities in asynchronous online learning. Results indicated that focusing on learners' cognitive abilities proved to be more effective than style-matching strategy for FD learners in both ill-structured and well-structured asynchronous online learning. Implications of the findings were discussed with suggestions for future research.

This chapter describes the college students’ online social communication patterns and behavior with a focus on the impact of individual differences on learners’ online communication. The study consisted of 27 college students who engaged in an online discussion over a period of fourteen weeks as part of requirements in an undergraduate educational technology course. The findings indicated that cognitive styles such as field dependence and field independence played a critical role in forming learners’ online social communication. Based on social compensation theory and Witkin et al.’s theory of individual differences, the authors claimed that effective individual communication in an online community can be fostered through creating learning support, taking into considerations factors like cognitive styles, complementary personality, interest and motivation in the process of design. Suggestions for future online learning are made with an emphasis on creating an effective online community for learning.

This chapter focuses on the design of human-computer interface, particularly the software interface design, by examining the relationship between the functionality and features of the interface and the cognitive factors associated with the design of such interface. A design framework is proposed followed by an empirical study to validate some of the theoretical assumptions of the framework. The findings indicate that learners become more perceptually engaged when a multiple sensory-input interface is used. Our study also shows that building affective interaction at the perceptual level could significantly enhance learners’ perceptual engagement which further leads them to cognitive engagement. Guidelines for designing an effective interface are proposed. The significance of the study is discussed with some suggestions for future study.
