In January 2014, 62 students graduated from the first for-credit course dedicated to Wikipedia. Learning focused on improved consumption of information, and collaborative construction of knowledge using the Wikipedia platform. This paper investigates the design and implementation of this course model, while highlighting the benefits and challenges to students & faculty. In addition to 128 medical articles in Hebrew Wikipedia, already viewed over 1.4 million times, students reported a unique learning experience that sharpened their collaborative skills as well as academic skills. This paper also presents the findings of a related study that focused on students’ learning experience, long-term impact and productive teaching practices. The study results helped fine-tune the pedagogical and administrative aspects of the course, influencing both teaching practices and the learning experience. Finally, the course is discussed in a wider educational perspective, presenting insights regarding reuse of the model, scaling possibilities and suggestions for further research.  相似文献

An experimental study involving 30 undergraduates (mean age = 20.5 years) in mental rotation (MR) training was conducted in an interactive Desktop Mental Rotation Trainer (iDeMRT). Stratified random sampling assigned students into one experimental group and one control group. The former trained in iDeMRT and the latter trained in conventional condition. A multifactorial pretest posttest design procedure was used and data were analysed using two-way analysis of covariance. Overall, there was substantial improvement in MR accuracy. Main effects of training and gender were observed, indicating that iDeMRT group and boys outperformed the control group and girls respectively. In addition, an interaction between training method and gender was present, indicating that boys were more accurate when trained in iDeMRT and performed moderately in conventional method. Female participants achieved equivalent improvement gain in MR accuracy regardless of the training conditions used. For the speed measure of MR, no appreciable improvement was observed after training.  相似文献

We add to research on embodied cognition by investigating the observational practices of amateur astronomers. Specifically, we take an interactionist perspective and examine how the body is recruited, moment by moment, as a resource for producing and communicating meaning during field activity. The data corpus is a set of ethnographic video records and field notes on the routines of a community of astronomers, especially small-group interactions during planning, searching for, observing, and confirming sight of a celestial target. Within this space, our analysis highlights how different modalities of embodied action and reasoning (gestures, tool use, gaze, touch, and others) were deployed and coordinated throughout the process of observing a celestial object and how those emerged in the transactions among participants. Our findings rehearse many issues and topics in the contemporary literature (e.g., gesturing for measuring or representationally) but also reveal important, novel forms of embodied action and reasoning in science, technology, engineering, and mathematics practices (e.g., training the eyes in averted vision and inscribing a celestial scene onto one’s hand). More broadly, these findings further affirm the power of interactionist analyses of knowing and learning while also surfacing areas in which expanded theorizing is needed to account for the full set of cognitive phenomena we observed.  相似文献

This study investigates the impact of an innovative conservation action campaign called Penguin Promises implemented at uShaka Sea World in Durban, South Africa. Communication tools included interpretive signage, exhibits with and without animals, presentations, and personal interactions, along with a specially designed postcard, on which visitors could write a promise (pledge) to make a change in their daily lives to become more environmentally responsible. Visitors who completed a card were contacted a year or more after their visit and asked about the outcomes of their promise. The results (N = 316) showed that 49.4% of respondents could give an example of something positive they had done for the environment, that they attributed to the campaign. Based on the study, recommendations are provided for the design of effective visitor conservation action campaigns.  相似文献

Abstract

In this study, we wished to investigate the factors that determine the direction of the spin axis of a pitched baseball. Nineteen male baseball pitchers were recruited to pitch fastballs. The pitching motion was recorded with a three-dimensional motion analysis system (1000 Hz), and the orientations of the hand segment in a global coordinate system were calculated using Euler rotation angles. Reflective markers were attached to the ball, and the direction of the spin axis was calculated on the basis of their positional changes. The spin axis directions were significantly correlated with the orientations of the hand just before ball release. The ball is released from the fingertip and rotates on a plane that is formed by the palm and fingers; the spin axis of the ball is parallel to this plane. The lift force of the pitched baseball is largest when the angular and translational velocity vectors are mutually perpendicular. Furthermore, to increase the lift forces for the fastballs, the palm must face home plate.  相似文献

Purpose: The ability to anticipate the actions of opponents can be enhanced through perceptual-skill training, though there is doubt regarding the most effective form of doing so. We sought to evaluate whether perceptual-skill learning would be enhanced when supplemented with guiding visual information. Method: Twenty-eight participants without soccer-playing experience were assigned to a guided perceptual-training group (n = 9), an unguided perceptual-training group (n = 10), or a control group (n = 9). The guided perceptual-training group received half of their trials with color cueing that highlighted either the key kinematic changes in the kicker's action or the known visual search strategy of expert goalkeepers. The unguided perceptual-training group undertook an equal number of trials of practice, but all trials were without guidance. The control group undertook no training intervention. All participants completed an anticipation test immediately before and after the 7-day training intervention, as well as a 24-hr retention test. Results: The guided perceptual-training group significantly improved their response accuracy for anticipating the direction of soccer penalty kicks from preintervention to postintervention, whereas no change in performance was evident at posttest for either the unguided perceptual-training group or the control group. The superior performance of the guided perceptual-training group was preserved in the retention test and was confirmed when relative changes in response time were controlled using a covariate analysis. Conclusions: Perceptual training supplemented with guiding information provides a level of improvement in perceptual anticipatory skill that is not seen without guidance.  相似文献

Children with disability continue to experience disadvantage in their school lives; thus, the question of what makes up an optimal school life, and whether this is different for children with disability, becomes critical. This paper reports on research into parental views about an optimal school life and the usefulness of Social Role Valorization theory as a framework for exploring this issue. Six focus group interviews were used to collect data from 30 parents. Children of a variety of ages, with and without disability, were represented. All groups were similar in the aspects they regarded as optimal in a child’s school life. These fell into five categories: being connected, growth, personhood, basic needs, and happiness. Despite this similarity across groups, there were some notable differences in the detail; for example, parents of children with disability had a stronger focus on children being wanted, high expectations, and being seen as an individual.  相似文献

This study explores and characterizes learners' participation patterns in MOOC forums, as well as the factors that correlate with learners' participation. Educational data mining and learning analytics methods were used to retrieve and analyze the learners' interpersonal interaction data, which had accumulated in the Coursera log files. The content in the forums was categorized based on Henri's criteria and converted into quantitative values that could be compared and visualized. It was found that only 20% of the learners were collaborating in the forums throughout the entire course and were responsible for 50% of the total posts. A portion of them earned the name “Super Active.” The analyses not only demonstrated the volume of activity and its pattern but also revealed the content of the discussions, which helped to highlight the needs and reasons for students' usage of the forums. The content analysis showed intensity in the “Cognitive” and “Discipline” categories. Thus, forum participants benefit from discussions not only socially but disciplinarily and cognitively as well. Furthermore, even though a strong significant correlation was found between the learners’ completion status and their activity in the forums, a group of learners, who did not complete the course, was highly active.  相似文献

Whilst graphical user interfaces (GUI) have gained much popularity in recent years, the need of the visually impaired to use applications in a non-visual environment is great. This paper promotes the provision of interfaces that allow users to access most of the functionality of existing GUIs using speech. This has been achieved by the design of a speech control tool that incorporates speech recognition and synthesis into existing packaged software, such as Teletext, the Internet or a word processor. The tool developed has taken the menu structure as a means of demonstrating what is accessible by the use of speech input and output. The tool provides the facility to dump screen text into clipboard and read it out loud. Adapting existing GUI applications in this way requires successful integration of speech, which in turn requires a profound understanding of the medium and the development of human engineering techniques.  相似文献

Letter sound knowledge, which, together with phonological awareness, is highly predictive of pre‐school children's reading acquisition, derives from children's knowledge of their associated letter names and the phonological patterns of those names. In this study of 66 monolingual pre‐school children we examined whether phonological patterns between letter names and their associated sounds might be differentially associated with aspects of phonological awareness. Results suggest that rudimentary levels of phonological awareness may facilitate the learning of letter sound associations. However, more explicit phonological awareness appears to be linked bi‐directionally with letter sound knowledge with diverse name‐sound associations, with letter sound associations that do not follow regular patterns (e.g. ‘juh’ for ‘j’ and ‘huh’ for ‘h’) most closely associated with performance in more complex phoneme awareness tasks.  相似文献
