The influence of learning style and training method on self-efficacy and learning performance in WWW homepage design training

The present study compares the relative effects of two training methods on learner's computer self-efficacy and learning performance in WWW homepage design. A field experiment was conducted by employing two classes of 10th graders. Results indicated that the behavior modeling training method yielded consistently superior performance and higher computer self-efficacy as compared with the instruction-based approach. Subjects with various learning styles performed substantially different in some learning tasks. The significant two-way interaction indicates the critical roles that gender and learning style played in interacting with training method. For learning performance, male students benefited more from the instruction-based and female students learned better in the behavior modeling condition. Concerning computer self-efficacy, female students gained more from the instruction and male students benefited more from behavior modeling approaches. For different learning style students, there exists a best-fit training approach. In addition, the best-fit training approach is task dependent. These results suggest that each individual training method has its unique merit to meet designated training objectives for learners with specific traits. Future research directions conclude the paper.

Substitutive competition: Virtual pets as competitive buffers to alleviate possible negative influence on pupils

Although competition is regarded as a powerful motivator in game‐based learning, it might have a negative influence, such as damage to confidence, on students who lose the competition. In this paper, we propose an indirect approach, substitutive competition, to alleviate such negative influences. The approach is used to develop a My‐Pet v3 system, in which pupils master subject materials to make their pets stronger, and compete against each other. Specifically, pupils learn Chinese idioms in a pet‐training game scenario, and their mastery of the material is related to the pets' strength to win the competition. The result of the competition is influenced by whether pupils spend enough effort on the learning tasks. This intention is expected to alleviate the negative influence that results from direct competition. A within‐subject experiment was conducted to examine the influence of substitutive competition. The results indicated that substitutive competition seems a promising scheme to maximise the power of competition. However, there were no apparent evidences in this study to demonstrate its effect to alleviate pupils' sense of failure, as compared with other two direct competition conditions.     

The effects of appeal types and candidates' poll rankings in negative political advertising

This paper combines the persuasion knowledge model (PKM) and priming theory to investigate the effects of different appeal types in negative political ads on voters' cognitive responses and candidate responses, and explore the moderating effect of an important candidate-related variable: poll ranking. The results indicate that negative advertising based on rational appeals is more beneficial to candidates who lag in the polls. However, negative ads based on emotional appeals generate better responses from voters when used by poll leaders. These effects are observed regardless of whether the race is between an incumbent and a challenger or two challengers.     

Investigating use continuance of data mining tools

While improving decisional quality is important to businesses, continued use of DMTs is a critical issue for managerial personnel. This problem mainly concerns the willingness of an individual to participate in the behavior. It can be further defined in a routine-based working behavior. This problem essentially involves three key issues, task fit, technology use, and habit. This study therefore integrates task-technology fit (TTF) model, expectation–confirmation mode (ECM), and habit, to examine the determinants of continued use of DMTs. Prior studies have focused on intention to use DMTs in the first time and only considered part of the three issues for identifying the determinants. 285 respondents from managerial personnel were collected to empirically evaluate this research model. The three issues are all important in influencing continuance use intention of DMTs. In particular, the task-technology fit indicates a direct effect on two factors of the technology use issue, user satisfaction and perceived usefulness, and an indirect effect on continuance use intention. User satisfaction and perceived usefulness, and habit are the key predictors of continuance use intention.

Transnational Governances in Higher Education: New Universities,Rhetorics, and Networks in Postwar Singapore

At the close of World War II, Japan’s ouster from Malaya led to the resumption of British control and a new outlook toward political independence. Higher education would play a central role in this complex transition, where the forces of decolonization and nation-building converged with drives toward both interethnic competition and multiethnic cooperation. These tensions stimulated a multiplicity of new rhetorics and new networks for universities and university students. This paper uses the framework of governance to uncover the contrasting rhetorics and networks produced by postwar Singapore’s new universities. By examining their structures and mechanisms of governance, the paper demonstrates how the sudden catapulting of university education to a crucial socio-political position redefined the intersections between education, language, culture, and nation. In doing so, it reveals that these redefinitions forecasted contemporary discourse and mechanisms in higher education.
