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

This survey-based study explored the mediated social attraction that a sample of Modern Family viewers had for Gloria Pritchett. Statistically speaking, viewers generally liked Gloria Pritchett, but her intersected social identity characterizations (e.g., harlot-spitfire prototype) guided her likability. Moreover, how viewers felt toward their ethnic, gender, and social class (not their membership in these groups) predicted viewer-character likability. Discussed are implications regarding the liking of Othered television characters and group identity, notions of intersectionality, and challenges associated with mainstream Latinidad. 相似文献

Linear factor analysis (FA) models can be reliably tested using test statistics based on residual covariances. We show that the same statistics can be used to reliably test the fit of item response theory (IRT) models for ordinal data (under some conditions). Hence, the fit of an FA model and of an IRT model to the same data set can now be compared. When applied to a binary data set, our experience suggests that IRT and FA models yield similar fits. However, when the data are polytomous ordinal, IRT models yield a better fit because they involve a higher number of parameters. But when fit is assessed using the root mean square error of approximation (RMSEA), similar fits are obtained again. We explain why. These test statistics have little power to distinguish between FA and IRT models; they are unable to detect that linear FA is misspecified when applied to ordinal data generated under an IRT model. 相似文献

This work presents the development of a scale of attitudes of secondary-school and university students towards animal welfare. A questionnaire was drawn up following a Likert-type scale attitude assessment model. Four components or factors, which globally measure animal welfare, are proposed to define the object of the attitude. The components are animal abuse for pleasure or due to ignorance (C1), leisure with animals (C2), farm animals (C3) and animal abandonment (C4). The final version of the questionnaire contains 29 items that are evenly distributed among the four components indicated, guaranteeing that each component is one-dimensional. A sample of 329 students was used to validate the scale. These students were aged between 11 and 25, and were from secondary schools in Aragon and the University in Zaragoza (Aragon's main and largest city, located in NE Spain). The scale shows good internal reliability, with a Cronbach's alpha value of 0.74. The questionnaire was later given to 1,007 students of similar levels and ages to the sample used in the validation, the results of which are presented in this study. The most relevant results show significant differences in gender and level of education in some of the components of the scale, observing that women and university students rate animal welfare more highly. 相似文献

An action research approach called soft systems methodology (SSM) was used to foster organisational learning in a school regarding the role of the learning support department within the school and its relation with the normal teaching‐learning activities. From an initial situation of lack of coordination as well as mutual misunderstanding and distrust among some of the actors in the situation, eight months of work yielded as a result a better working environment among the participants, the creation of a volunteer discussion group functioning on a permanent basis, and a clarification and modification of some of the learning support activities. This change can also be described as learning by learning support staff, school teachers and administrators on how to work together, as well as on how to support children's learning in a better way. Nevertheless, another event that occurred after the intervention shows the importance of considering a wider system than that limited by the participants in the intervention. 相似文献

Pigeons’ choices between larger, more delayed and smaller, less delayed reinforcers were examined while the pigeons lived in the experimental chamber for 23-h sessions. In Condition 1, 4 pigeons were food deprived prior to each session and exposed to one session every 4th day. Condition 2 was identical except that the pigeons began each session at their ad-lib weights. Condition 3 was identical to Condition 2 except that sessions were conducted on consecutive days. Condition 4 was identical to Condition 3 except that the subjects (2 pigeons from Conditions 1–3 plus a naive pigeon) could obtain reinforcers much less frequently. In all of the conditions, the pigeons consistently chose the smaller, less delayed reinforcers; the pigeons were impulsive. The restriction of food access caused a disruption in the diurnal pattern of feeding, but did not decrease impulsiveness even in this 23-h live-in procedure. 相似文献
