One of online distance learning’s positive attributes is its flexibility. However, the possibility of engaging in periods of non-enrollment (breaks) usually ends in students dropping out. In this paper, the intention to continue of those students who have not enrolled in the second semester is analyzed, adopting a long-term program perspective. This continuance intention is compared with the subsequent restart (or dropping out) in the third semester. This analysis has confirmed that the models of continuance intention and effective re-enrollment are essentially different. Continuance intention is more rational, even logical, and is mainly based on the level of satisfaction or dissatisfaction with the educational experience (difficulty of the learning materials or perception of the learning system). Effective re-enrollment is more practical or pragmatic, with more importance given to the effects of student dimension variables, for example, motivations for studying, previous university experience, or environmental variables, such as having a job. 相似文献

The purpose of the present work is to describe the progression in the conceptions of prospective primary teachers about school
science content while they were participating in three teacher education courses following the same constructivist oriented
strategy. The participants’ written output was analyzed in various categories—selection of content, types of content and their
relationships, levels of complexity, and presentation of content to pupils. There was evidence for some progress in their
conceptions of the content from a traditional view to another that we termed intermediate since it did not reach the vision
that we consider to be the most complex. Finally, we present a General Itinerary of Progression on school content that could
serve as a referent for initial teacher education. 相似文献

In an experiment with rats, an appetitive conditioning method was used to investigate the generality of the hypothesis that
extinction should arouse attention to contextual cues, resulting in all learning in that context becoming context specific.
Rats received appetitive conditioning with a tone either while extinction of a flasher occurred (Group With Extinction) or
while it did not (Group No Extinction). Half of each group was subsequently tested in extinction in the context in which training
had taken place or in a different context. The results revealed a three-way interaction of extinction and context with trials,
in a direction opposite to the one the hypothesis would suggest. When rats were tested in a different context, there was generally
better responding in Group With Extinction than in Group No Extinction. In the same context, there was generally lower responding
in Group With Extinction than in Group No Extinction. Subsequent testing showed an ABA recovery effect. Results are discussed
in terms of the challenges they pose for the revised retrieval theory presented by Callejas-Aguilera and Rosas (2011). 相似文献

Proper field delineation plays an important role in scientometric studies, although it is a tough task. Based on an emerging and interdisciplinary field nanoscience and nanotechnology– this paper highlights the problem of field delineation. First we review the related literature. Then, three different approaches to delineate a field of knowledge were applied at three different levels of aggregation: subject category, publication level, and journal level. Expert opinion interviews served to assess the data, and precision and recall of each approach were calculated for comparison. Our findings confirm that field delineation is a complicated issue at both the quantitative and the qualitative level, even when experts validate results. 相似文献

AbstractThe visual behaviour is a determining factor in sailing due to the influence of the environmental conditions. The aim of this research was to determine the visual behaviour pattern in sailors with different practice time in one star race, applying a probabilistic model based on Markov chains. The sample of this study consisted of 20 sailors, distributed in two groups, top ranking (n = 10) and bottom ranking (n = 10), all of them competed in the Optimist Class. An automated system of measurement, which integrates the VSail-Trainer® sail simulator and the Eye Tracking SystemTM was used. The variables under consideration were the sequence of fixations and the fixation recurrence time performed on each location by the sailors. The event consisted of one of simulated regatta start, with stable conditions of wind, competitor and sea. Results show that top ranking sailors perform a low recurrence time on relevant locations and higher on irrelevant locations while bottom ranking sailors make a low recurrence time in most of the locations. The visual pattern performed by bottom ranking sailors is focused around two visual pivots, which does not happen in the top ranking sailor's pattern. In conclusion, the Markov chains analysis has allowed knowing the visual behaviour pattern of the top and bottom ranking sailors and its comparison. 相似文献

Dyslexia is a specific learning disability characterized by difficulties with accurate and/or fluent word recognition and
by poor spelling abilities. The absence of other high level cognitive deficits in the dyslexic population has led some authors
to propose that non-strategical processes like implicit learning could be impaired in this population. Most studies have addressed
this issue by using sequence learning tasks, but so far the results have not been conclusive. We test this hypothesis by comparing
the performance of dyslexic children and good readers in both implicit and explicit versions of the sequence learning task,
as well as in another implicit learning task not involving sequential information. The results showed that dyslexic children
failed to learn the sequence when they were not informed about its presence (implicit condition). In contrast, they learned
without significant differences in relation to the good readers group when they were encouraged to discover the sequence and
to use it in order to improve their performance (explicit condition). Moreover, we observed that this implicit learning deficit
was not extended to other forms of non-sequential, implicit learning such as contextual cueing. In this case, both groups
showed similar implicit learning about the information provided by the visual context. These results help to clarify previous
contradictory data, and they are discussed in relation to how the implicit sequence learning deficit could contribute to the
understanding of dyslexia. 相似文献

Advanced displays and natural user interfaces (NUI) are a very suitable combination for developing systems to provide an enhanced and richer user experience. This combination can be appropriate in several fields and has not been extensively exploited. One of the fields that this combination is especially suitable for is education. Nowadays, children are growing up playing with computer games, using mobile devices, and other technological devices. New learning methods that use these new technologies can help in the learning process. In this paper, two new methods that use advanced displays and NUI for learning about a period of history are presented. One of the methods is an autostereoscopic system that lets children see themselves as a background in the game and renders the elements in 3D without the need for special glasses; the second method is a frontal projection system that projects the image on a table in 2D and works similarly to a touch table. The Microsoft Kinect© is used in both systems for the interaction. A comparative study to check different aspects was carried out. A total of 128 children from 7 to 11 years old participated in the study. From the results, we observed that the different characteristics of the systems did not influence the children's acquired knowledge, engagement, or satisfaction. There were statistically significant differences for depth perception and presence in which the autostereoscopic system was scored higher. However, of the two systems, the children considered the frontal projection to be easier to use. We would like to highlight that the scores for the two systems and for all the questions were very high. These results suggest that games of this kind (advanced displays and NUI) could be appropriate educational games and that autostereoscopy is a technology to exploit in their development. 相似文献

How important is the role that the different social institutions play in adolescents’ emotional development? This study alludes to the social capital framework to explain the influence that the family, school and peer relations have on the social-emotional competencies (SEC) of adolescents, immigrants and locals living in Southeastern Spain. Three social capital and socio-emotional competencies assessments scales were used in the study with 1614 pupils from 7 secondary schools. The results show that: (1) The social capital is a predictive and explanatory factor in adolescence. (2) The social relations that influence the SEC the most are those developed at school, followed by peer relations and, lastly, the family. (3) Spanish and Romanian teenagers show higher social capital and more SEC than Moroccans. (4) There are SEC gender differences among the Spanish group. (5) An immigrant school puzzle is observed in the Moroccan teenagers group who value school the most. (6) The family’s low emotional influence, particularly among Moroccan women, suggests that there is a deterioration of the institution and the existence of inter-generational differences. According to the results, schools remain a privileged space for SEC intervention programmes. 相似文献
