Applying the technology acceptance model in a study of the factors affecting usage of the Taiwan digital archives system
(2011-01-01) Hong, J. C.; Hwang, M. Y.; Hsu, H. F.; Wong, W. T.; Chen, M. Y.
The rapid development of information and communication technology and the popularization of the Internet have given a boost to digitization technologies. Since 2001, The National Science Council (NSC) of Taiwan has invested a large amount of funding in the National Digital Archives Program (NDAP) to develop digital content. Some studies have indicated that most respondents had no confidence in particular digital archive websites. Thus, with the Technology Acceptance Model (TAM) as a theoretical basis, the focus of the present study was to identify the factors influencing usage. Extension of the roles of perceived playfulness and interface design was also explored to identify the reasons that digital archives might not be accepted by some users. The present study used a random sampling method to distribute questionnaires to digital archive users via e-mail. The Structural Equation Modeling (SEM) method was used to verify the appropriateness of the study model and whether the hypotheses were confirmed. Study results indicated that the “interface design” is an important factor that influences people to use the digital archives, and that it is separate from the “human factor” and the “human–computer interface” (HCI). Moreover, the results showed that HCI had a significant impact on the “perceived ease of use” and on “usage intentions.” However, the human factor interface showed a significant impact only on “perceived ease of use.” With respect to the hypotheses regarding “usage intentions,” the “perceived usefulness,” “perceived ease of use,” “attitude,” and “perceived playfulness” were not related to “usage intentions.” Therefore, it is necessary to consider the quality of interface design in the development of digital archives in order to promote usage.
Collaborative learning in technological project design
(2010-01-01) Hong, J. C.; Yu, K.C.; Chen, M. Y.
The POWERTECH contest in Taiwan was established in an attempt to promote inventiveness and technology to elementary school pupils. The POWERTECH contest is designed as a collaborative learning system for project design. Project design is comprised of technical processes, which include the construction of an artifact and improvement of its functions. Thus, pupils learn scientific and technical knowledge through a collaborative design project. The purpose of the study was to examine how collaborative learning could be facilitated in technological project design, and whether and how pupils working collaboratively were able to share their design ideas. The study was carried out by analyzing the design portfolio compiled by a team of four elementary school pupils who were engaged in a collaborative design project that focused on making a robot rat for the POWERTECH contest. A portfolio analysis was used in this study to help researchers assess the actual collaboration process among the team members. The study indicated that collaborative learning in a contest facilitated the sharing of knowledge and resources among the team members. Furthermore, reflections essential for problem-solving among the team members were often raised during the design process. These reflections were also conducive to the reduction of mistakes during the contest.
Developing physics concepts through hands-on problem solving: A perspective on a technological project design
(2011-01-01) Hong, J. C.; Chen, M. Y.; Wong, A.; Hsu, T. F.; Peng, C. C.
In a contest featuring hands-on projects, college students were required to design a simple crawling worm using planning, self-monitoring and self-evaluation processes to solve contradictive problems. To enhance the efficiency of problem solving, one needs to practice meta-cognition based on an application of related scientific concepts. The objective of this study, then, was to analyze the physics concepts employed by the students as they completed a hands-on project named Crawling Worm, during which they had to overcome problems encountered by the requirements of their design as well as those brought on by competition. Based on the analysis of the participants’ working portfolios and on reviews and interviews by engineering professors, the results of this study show that the crawling worm design competition encouraged the practice of problem solving, and it facilitated the learning of physics concepts such as friction, torque, four bar link, material properties, and so on.
