This study adopted design and development research methodology (Richey & Klein, Design and development research: Methods, strategies, and issues, 2007) to systematically investigate the process of applying instructional design principles, human–computer interaction, and software
engineering to a performance support system (PSS) for behavior management in a classroom. The purpose was to examine how a
proposed instructional design framework based on Ausubel’s (The psychology of meaningful verbal learning, 1963) advance organizer theoretical approach could be used to address inherent problems of technically driven PSSs. Development
data were collected from a six-phase participatory rapid prototyping process using both qualitative and quantitative methods.
Findings indicated that (a) the advance organizer concept combined with a matrix design metaphor provided an effective way
to illustrate conceptual connections and relations among PSS modules and their elaborated information, (b) the system served
as a reference to support participants for exchanging ideas with other teachers as well as with parents of students, and (c)
the rapid prototyping process established parameters that helped the project team maintain a focus on users and collect data
useful for advancing to a higher phase of system development. Potential drawbacks pertaining to the proposed design strategies
and their possible corrective actions are also reported and discussed. 相似文献

Dynamic response of functional virtual prototyping of motorcycle under combined excitations 总被引：1，自引：0，他引：1
This paper developed 3D product models of motorcycle and engine by UGNX as well as virtual prototyping by ADAMS program with road roughness generated by MATLAB. Under the straight-line running condition, the dynamic responses of motorcycle multibody system to both road and engine excitations were compared with those to only road excitation in terms of vertical acceleration response, amplitude frequency response and power spectral density. The comparisons of simulation data showed that the response due to flat road excitation was around 20 Hz, while that to the combined excitations was in a wide frequency band, of which the major components focused on 10 Hz, 15 Hz, 35 Hz ,70 Hz, 100 Hz and even higher frequencies, reflecting the characteristics of engine excitation based on its unbalanced inertia force and torque. It is concluded that the high fidelity virtual prototyping can simulate the dynamics of motorcycle product well in investigating the vibration and ride comfort performance. 相似文献

To examine interface issues in an educational software program, we recruited twenty-two users in health sciences departments for a usability study. Using the GramStain-Tutor™ (GST) CD-ROM, these users performed tasks in navigating the program and using various interactive features. Their actions and comments were recorded with a digital video recorder and an audio recorder. The main results of our study are: (a) the majority of the users did not use the multiple navigational options available in the program; (b) navigational patterns differed based on the training background and content knowledge of the users; (c) several visual cues critical to program use were not discovered by the majority of the users; and (d) icons representing specific functions were not intuitive from users' perspectives. We demonstrated how a usability study of a relatively small number of users can identify specific problems in interface design. We recommend these interface problems be addressed before conducting educational studies that examine how educational software programs affect student learning. 相似文献

基于就业能力的大学生就业指导效果的实证研究 总被引：11，自引：0，他引：11
大学生的就业能力与实际就业关系密切,是影响就业指导工作成效的重要指标。通过对“大学生就业能力问卷”调查结果的因素分析,发现大学生就业能力包括四个因素:应聘能力、团队能力、创新能力和个性特征;用四维结构的就业能力衡量就业指导课程培训效果时发现,参训学生的应聘能力和团队能力方面得到显著改善,而创新能力和个性特征则没有发现明显改善。通过对“上海交通大学2006届毕业生调查问卷”所得数据的回归分析,发现就业能力中三个维度———团队能力、创新能力和个性特征对就业满意度有显著的贡献。最后对研究结论的意义进行了讨论。 相似文献

In Shanghai, a mega-city of approximately 24.15 million people (Shanghai Municipal Statistics Bureau, 2015, “Art. 13”), the population of migrant workers continues to increase. According to the Shanghai Municipal Statistics Bureau (2015), as of 2015, 9.81 million residents did not have household registration papers. Of these, 70%, or 6.87 million were migrant workers (“Art. 13”). The researcher relied on qualitative research techniques to explore the outcomes of an after-school program for the children of migrant workers. The study took place over a four-year period with data being collected throughout. Keeping in mind methodology limitations, the analysis affirmed the success of the hoped for outcomes of the program 相似文献

One approach to the development of software, which has received considerable attention in the software engineering literature, is rapid prototyping. We describe the rapid prototyping methodology and discuss some of its advantages and disadvantages. We then focus on the use of rapid prototyping in the project component of the typical undergraduate software engineering course. Several approaches to prototyping are described, along with various automated tools that support prototyping. Our experiences with prototyping in our undergraduate software engineering course are described, and we draw a number of conclusions vis a vis the use of prototyping. 相似文献

Rapid prototyping: An alternative instructional design strategy 总被引：1，自引：15，他引：1
Steven D. Tripp Barbara Bichelmeyer 《Educational technology research and development : ETR & D》1990,38(1):31-44
There is a design methodology calledrapid prototyping which has been used successfully in software engineering. Given the similarities between software design and instructional design, we argue that rapid prototyping is a viable model for instructional design, especially for computer-based instruction. Additionally, we argue that recent theories of design offer plausible explanations for the apparent success of rapid prototyping in software design. Such theories also support the notion that rapid prototyping is appropriate for instructional design. We offer guidelines for the use of rapid prototyping and list possible tradeoffs in its application. 相似文献

This article explores the shift from observation of users to participation with users, describing and investigating three examples of user-centered design practice in order to consider the new ethical demands being made of technical communicators. Pelle Ehn's participatory design method, Roger Whitehouse's design of tactile signage for blind users, and the design of an online writing program are explored for the creation of a dialogic design ethic. The development of effective collaborative design methods requires meaningful communication between users and designers, and dialogic ethics can guide the development of effective and humane technological design methods. 相似文献
