Competent instructional designers must have specific skills to successfully facilitate learning and to improve the performance of individuals and organizations. While some authors and professional organizations have identified the capabilities required for effective instructional designers, only a few have validated these skills by collecting data from actual practitioners. The purpose of this article is to discuss the results of a research study we conducted to identify and empirically validate competencies for instructional design professionals. 相似文献

From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central
to a domain can maximize students’ effort associated with constructing new schemas. In addition, interfaces that minimize
working memory demands due to the interface per se, for example by mimicking existing non-digital work practice, can preserve
students’ attentional focus on their learning task. In this research, we asked the question: What type of interface input capabilities provide best support for science problem solving in both low- and high-performing students? High school students’ ability to solve a diverse range of biology problems was compared over longitudinal sessions while
they used: (1) hardcopy paper and pencil (2) a digital paper and pen interface (3) pen tablet interface, and (4) graphical
tablet interface. Post-test evaluations revealed that time to solve problems, meta-cognitive control, solution correctness,
and memory all were significantly enhanced when using the digital pen and paper interface, compared with tablet interfaces.
The tangible pen and paper interface also was the only alternative that significantly facilitated skill acquisition in low-performing
students. Paradoxically, all students nonetheless believed that the tablet interfaces provided best support for their performance,
revealing a lack of self-awareness about how to use computational tools to best advantage. Implications are discussed for
how pen interfaces can be optimized for future educational purposes, and for establishing technology fluency curricula to
improve students’ awareness of the impact of digital tools on their performance. 相似文献

This article traces how citizenship in Hong Kong is constructed via familial tropes that privilege sameness and a politics of identification; this rhetorical representation, I argue, not only perpetuates a jus sanguinis model of citizenship that privileges ethnic blood ties, but also allows the state and the dominant citizenry to justify neoliberal and racist practices that exclude brown bodies. By analyzing the citizenship claims made by the marginalized South Asian community in Hong Kong and the subsequent responses they receive from the mainstream public, I demonstrate that racialized populations face a rhetorical double bind: on the one hand, they must deploy the familial metaphors commonly used by the existing citizenry to demonstrate their sense of belonging, but, on the other hand, such tropes reinscribe them in a power hierarchy that undermines their subjectivity. This case study illuminates that while it is commonly seen as a viable rhetorical tactic for marginalized rhetors to resist and participate, the repurposing and redeployment of dominant tropes have significant limitations as they are constricted by power structures that are staunchly in place. 相似文献

There is now widespread agreement that America's schools are in serious trouble. However, there is little consensus regarding what should be done about it. The school reforms currently being suggested are the most radical since the elimination of the one room school. School reforms of the 1980s—personnel selection, job redesign, evaluation/ feedback, incentives, instructional technology, and organization rede-sign—are reviewed from a performance technology perspectivee Reasons for their lack of success are discussed, in particular the schools' lack of interest in instructional design and technology. The most likely future reforms, those that involve the organizational redesign of schools, are discussed along with the impact such changes would have on the potential for applying performance technology in the schools. The paper concludes with actions that performance technologists in both business and academic environments can take to encourage the application of their technologies in the schools. 相似文献

In criterion‐referenced tests (CRTs), the traditional measures of reliability used in norm‐referenced tests (NRTs) have often proved problematic because of NRT assumptions of one underlying ability or competency and of variance in the distribution of scores. CRTs, by contrast, are likely to be created when mastery of the skill or knowledge by all or most all test takers is expected and thus little variation in the scores is expected. A comprehensive CRT often measures a number of discrete tasks that may not represent a single unifying ability or competence. Hence, CRTs theoretically violate the two most essential assumptions of classic NRT re liability theory and they have traditionally required the logistical problems of multiple test administrations to the same test takers to estimate reliability. A review of the literature categorizes approaches to reliability for CRTs into two classes: estimates sensitive to all measures of error and estimates of consistency in test outcome. For single test administration of CRTs Livingston's k2is recommended for estimating all measures of error, Sc is proposed for estimates of consistency in test outcome. Both approaches compared using data from a CRT exam and recommendations for interpretation and use are proposed. 相似文献
