This article reports on a case of participatory self-directed online learning within the context of a graduate-level instructional technology course. The course was about online learning environments and relied on both asynchronous and synchronous technologies. In this case, the instructor and students engaged in collaborative course design through one of the assignments where student teams and the instructor led one week’s worth of course activities and discussions. This article begins with a discussion of the literature on participatory self-directed online learning. Then, the article presents an overview of the course design, detailed discussion of the assignment that framed student participatory self-directed learning and two examples of student assignments. The framing question for organising this case was as follows: What lessons can a team of graduate students and the instructor learn about self-directed participatory online learning from a collaborative design project? The article ends with the overall lessons learned from the case and implications to future design of online activities.  相似文献

The creation of several forms of knowledge that would enable organizations to ask and say the right things during complex diagnoses is proposed. Based on the concept of knowledge combustion, the hypothesis testing knowledge blend (HTKB) is the cognitive equivalent of petrol for the combustion engine. The HTKB requires the creation of a knowledge hybrid that uses existing technologies to ask and say the right things. In addition to timing mechanisms and problem space maps, two forms of declarative knowledge (directions and explanations) are integrated to create the HTKB. These directions and explanations would be obtained directly from the video recordings of diagnosticians conducting teleconsultations. By providing these profound dialogues during the conduct of complex diagnoses, the HTKB should increase the knowledge capital of organizations. Formal analyses are beginning to validate the conceptual structure (blue print) presented in this paper, and the results will be provided in the future.  相似文献

This paper considers the ways that Information Ethics (IE) treats things. A number of critics have focused on IE’s move away from anthropocentrism to include non-humans on an equal basis in moral thinking. I enlist Actor Network Theory, Dennett’s views on ?as if’ intentionality and Magnani’s characterization of ?moral mediators’. Although they demonstrate different philosophical pedigrees, I argue that these three theories can be pressed into service in defence of IE’s treatment of things. Indeed the support they lend to the extension of moral status to non-human objects can be seen as part of a trend towards the accommodation of non-humans into our moral and social networks. A number of parallels are drawn between philosophical arguments over artificial intelligence and information ethics.  相似文献

Previous research has demonstrated that cognitive test validities are generalizable and predictive of academic performance across situations. However, even after accounting for statistical artifacts (e.g., sampling error, range restriction, criterion reliability), substantial variability often remains around estimates of cognitive test–performance relationships suggesting the presence of additional moderators. In the present study, we examine the sources of institutional variation in Scholastic Aptitude Test (SAT) validity across a sample of 110 institutions. Institutional characteristics moderated the size of SAT validities, such that more selective schools and schools that emphasize traditional assessment techniques (i.e., school records, standardized tests) showed higher SAT validities while schools that were larger and where students demonstrated more financial need, schools that emphasized the usage of alternative assessment techniques (i.e., essays, letters of recommendations, extracurricular activities), and schools that enrolled higher percentages of historically disadvantaged minority students generally exhibited lower SAT validities. Future directions in the understanding of situational influences on SAT–grade point average validities are discussed.  相似文献

In this paper we introduce certain constants that characterize exponential stability or exponential unstability of discrete linear time varying systems. We also present bounds for Lyapunov and Perron exponents in terms of the introduced constants.  相似文献

Research on ecological literacy often takes for granted that participants understand, and can construct the meaning within, the complex concepts involved, simply because they are able to use the appropriate terminology in a ‘fluent’ manner and/or can select the correct option on multiple choice tests. In this study, and in the larger two-year study it is part of, a trend has been unearthed regarding the ecological literacy of university students entering into a Bachelor of Education program. An analysis of the meaning contained in participant definitions has revealed that the vast majority of teacher candidates, graduates of many different universities, are unable to explain the meaning of key integrating ecological concepts at even a minimal level of maturity, alluding to a possible systemic problem. The findings, though preliminary, suggest that until we inquire into the meaning that teachers possess for key concepts rather than accepting fluent but shallow use of these concepts, we may be taking too much for granted.  相似文献

Although it is well established that Black male students are underrepresented in gifted educational programs in the United States, due to a scarcity of longitudinal prospective research, little is known about the protective factors at the child, family, and school level that increase the probability of Black male students being identified as gifted during early elementary school. Using data from the Miami School Readiness Project, we followed 6,926 low-income Black males from preschool through 5th grade to describe trajectories for the 453 Black males (6.5 %) who were identified as gifted, and examined child, family, and preschool variables associated with gifted classification. Boys were most commonly identified as gifted in first and second grade, and 15 % of the identified boys did not appear to be receiving gifted courses. Hierarchical multiple logistic regression analyses revealed that being classified as gifted in early elementary school was more likely for Black males who (a) attended public school pre-K programs at age four, (b) had higher cognitive, language, fine motor, behavioral, and emergent literacy school readiness skills before entering kindergarten, (c) spoke a language other than English at home, (d) were older upon entering kindergarten, (e) received higher grades in school, and (f) scored higher on standardized tests of math and reading. Predictors of gifted identification in the kindergarten year were different and weaker compared to identification in later years. Implications for early identification and intervention for talented Black males are discussed.  相似文献

The present study examined the interactive effects of school norms, peer norms, and accountability on children's intergroup attitudes. Participants (= 229) aged 5–11 years, in a between‐subjects design, were randomly assigned to a peer group with an inclusion or exclusion norm, learned their school either had an inclusion norm or not, and were accountable to either their peer group, teachers, or nobody. Findings indicated, irrespective of age, that an inclusive school norm was less effective when the peer group had an exclusive norm and children were held accountable to their peers or teachers. These findings support social identity development theory (D. Nesdale, 2004, 2007), which expects both the in‐group peer and school norm to influence children's intergroup attitudes.  相似文献
