Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes. 相似文献

As low-stakes testing contexts increase, low test-taking effort may serve as a serious validity threat. One common solution to this problem is to identify noneffortful responses and treat them as missing during parameter estimation via the effort-moderated item response theory (EM-IRT) model. Although this model has been shown to outperform traditional IRT models (e.g., two-parameter logistic [2PL]) in parameter estimation under simulated conditions, prior research has failed to examine its performance under violations to the model’s assumptions. Therefore, the objective of this simulation study was to examine item and mean ability parameter recovery when violating the assumptions that noneffortful responding occurs randomly (Assumption 1) and is unrelated to the underlying ability of examinees (Assumption 2). Results demonstrated that, across conditions, the EM-IRT model provided robust item parameter estimates to violations of Assumption 1. However, bias values greater than 0.20 SDs were observed for the EM-IRT model when violating Assumption 2; nonetheless, these values were still lower than the 2PL model. In terms of mean ability estimates, model results indicated equal performance between the EM-IRT and 2PL models across conditions. Across both models, mean ability estimates were found to be biased by more than 0.25 SDs when violating Assumption 2. However, our accompanying empirical study suggested that this biasing occurred under extreme conditions that may not be present in some operational settings. Overall, these results suggest that the EM-IRT model provides superior item and equal mean ability parameter estimates in the presence of model violations under realistic conditions when compared with the 2PL model. 相似文献

The purpose of this study was to investigate the potential for using case‐based pedagogy as a context for collaborative inquiry into the teaching and learning of elementary science. The context for this study was the elementary science teacher preparation program at West Visayas State University on the the island of Panay in Iloilo City, the Philippines. In this context, triple linguistic conventions involving the interactions of the local Ilonggo dialect, the national language of Philipino (predominantly Tagalog) and English create unique challenges for science teachers. Participants in the study included six elementary student teachers, their respective critic teachers and a research team composed of four Filipino and two U.S. science teacher educators. Two teacher‐generated case narratives serve as the centerpiece for deliberation, around which we highlight key tensions that reflect both the struggles and positive aspects of teacher learning that took place. Theoretical perspectives drawn from assumptions underlying the use of case‐based pedagogy and scholarship surrounding the community metaphor as a referent for science education curriculum inquiry influenced our understanding of tensions at the intersection of re‐presentation of science, authority of knowledge, and professional practice, at the intersection of not shared language, explicit moral codes, and indigenization, and at the intersection of identity and dilemmas in science teaching. Implications of this study are discussed with respect to the building of science teacher learning communities in both local and global contexts of reform. © 2001 John Wiley & Sons, Inc.

This article introduces a research study on student model formation and development in introductory mechanics. As a point
of entry, I present a detailed analysis of the Long Decay Model of one-dimensional projectile motion. This model has been
articulated by Galileo (in De Motu) and by contemporary students. Implications for instruction are discussed.

This study examined the relationship between adolescents’ attachment style and their decision to enter mentoring relationships. The participants were 569 Greek Cypriot high school students. It was found that adolescents who have a mentor are more secure in their attachment than those who do not. Girls with low scores in secure attachment do not enter easily into mentoring relationships. Older adolescents are more anxious in their attachments, probably because they can better appreciate the possible difficulties if something goes wrong; thus, they are more reluctant to take the risk of starting a mentoring relationship than younger students. Furthermore, secure attachment was found to be positively correlated to the perceived impact of the whole experience: the more secure the attachment, the stronger the mentoring bond seems to be. 相似文献

Adolescent success providing satisfying support in response to a close friend's call in a caregiving task was examined as a potentially fundamental developmental competence likely to predict future social functioning, adult caregiving security, and physical health. Adolescents (86 males, 98 females; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other) were followed from ages 13 to 33 (1998–2021) using multiple methods and reporters. Early caregiving success was found to predict greater self- and partner-reported caregiving security, lower negativity in adult relationships, and higher adult vagal tone. Results are interpreted as advancing our understanding beyond simply recognizing that adolescent friendships have long-term import, to now identifying specific capacities within friendships that are linked to longer-term outcomes. 相似文献

The evaluation of faculty development programs 总被引:1,自引:0,他引:1
This article reviews literature pertinent to the evaluation of faculty development programs and presents data from several studies conducted at two institutions. These data were consistent with those previously reported in that faculty participants consistently expressed satisfaction with development services. In addition, one study found that most faculty members voluntarily took some action to improve their instructional effectiveness, though only a minority pursued these efforts in depth. Volunteers who worked intensively with a faculty development consultant improved more on objective measures of effectiveness than did those who were only superficially involved in improvement efforts; those who received no consultative assistance failed to improve significantly. Evidence from a final study provided a control for faculty motivation and led to the conclusion that improvement was contingent both on faculty desire to improve and on the availability of professional assistance. 相似文献
