Familiarity with learning contexts is important in the field of mobile-assisted language learning (MALL). Several review studies on MALL have been published to date. However, scholars have not covered certain aspects of familiar contexts in their reviews, such as which learning/instructional methodologies support learning in familiar contexts or what the affordances of familiar contexts are for language learning. To address this gap, the authors in this study reviewed research articles related to MALL in familiar, authentic environments published in the past 10 years. The reviewed articles were from journals published in the Social Science Citation Index between 2009 and 2018. The main aim of this study was to review the published articles to understand (1) pedagogical approaches, (2) data collection, (3) locations, (4) affordances of authentic environments and (5) issues in MALL research. The results revealed that the most frequent items in reviewed articles were task-based learning and communicative language teaching (pedagogical approaches); questionnaires, pretest and posttests and interviews (data collection); the local community and campus (locations); daily encounters, language learning and cognitive load (affordances of authentic environments); and small sample sizes and short-term interventions (issues in MALL research). Based on the results, the authors in this study made several suggestions and provided implications for educators and researchers in the field about MALL in familiar, authentic environments. 相似文献

For this study the researchers designed learning activities to enhance students’ high level cognitive processes. Students learned new information in a classroom setting and then applied and analyzed their new knowledge in familiar authentic contexts by taking pictures of objects found there, describing them, and sharing their homework with peers. An experiment was carried out in which 58 junior high school students were divided into a control (n = 30) and an experimental (n = 28) group. The control group studied and completed learning activities with traditional textbooks while the experimental group used electronic textbooks and a learning system, Virtual Pen for Tablet PC (VPenTPC), in order to gauge the feasibility of the proposed approach. The post-test results show a significant difference between the control and experimental groups. In our analysis of the various approaches students took to complete the task, we were able to identify thirty cognitive and metacognitive strategies for using mobile technology, from which we selected the ten most frequently used ones. The results show that low ability students make better use of strategies than their high ability peers, resulting in significant learning gains. The results also show that most students perceive VPenTPC positively. Based on these results, we suggest some implications along with conclusions and directions for future research. 相似文献

The purpose of this study was to explore students’ conceptions of context-aware ubiquitous learning (u-learning). The students participated in a u-learning exercise using PDAs equipped with RFID readers. The data were collected from individual interviews with each of the students by a trained researcher, and the responses of the interviewees were further analyzed using the phenomenographic method. The analysis revealed five categories of conceptions of u-learning, including “u-learning as the application of technology,” “u-learning as a platform for attaining information,” “u-learning as a timely guide,” “u-learning as increase of knowledge” and “u-learning as active learning.” There conceptions are viewed as a hierarchy, from less advanced to more sophisticated. An in-depth analysis of the students’ conceptions of learning indicated that students held multiple conceptions of u-learning. This study further suggests that inquiry practices (such as allowing open-ended exploration for the learning topic) should be addressed in u-learning activities, as these practices may foster more sophisticated conceptions of u-learning. 相似文献

In this study we content analyzed the online discussion of several senior-high-school groups on a forum of a virtual physics
laboratory in Taiwan. The goal of our research was to investigate the nature of non-course-based online discussion and to
find out some useful guidelines in developing such discussion forums for learning purposes. We adapted Henri’s framework and
models (1992) for our analysis. The content analysis was conducted in terms of participation rate, social cues, interaction
types, and cognitive and metacognitive skills. In this study, we compared the result patterns of two discussion conditions
(‘required’ (R-) condition versus ‘non-required’ (NR-) condition) of a non-course-based discussion forum and investigated
how the quality of message content changed in the processes of discussion. In the R-condition, participants were required
to reply to the thread before they were allowed to read other messages on the forum, whereas participants in the NR-condition
were not restricted to this demand. The results showed that for both conditions, the most frequently involved interaction
type was ‘direct response’, and the most frequently used cognitive skill was ‘elementary clarification’. Fewer participants
of the R-condition strayed from the subject under discussion in comparison to the NR-condition. However, larger percentage
of message content containing metacognitive components was found in the NR-condition. When taking the sequences of postings
into account, we found that for the R-condition, the percentage of metacognitive component in the message content tended to
increase in the up-third postings, whereas for the up-third postings of the NR-condition the percentage of non-cognitive components
substantially increased. Overall, the results of our study indicated that the way in which participants used cognitive and
metacognitive skills during the discussions was related to the discussion conditions. The initial requirement of reply fostered
the use of cognitive skills, but it did not necessarily induce the use of high-level cognitive or metacognitive skills. We
concluded that beside the discussion conditions the moderators’ guidance would be influential in determining the quality of
online discussion on a non-course-based discussion forum.

Dichroa Lour., a small genus of Saxifragaceae, contains about 12 species,
ranging from the mainland of S. E. Asia southward to Pacific islands. But most of
the species are more restricted in distribution. Of the 12 recognized species, six are
known from South China and Indochina; three are confined to west and northwest
New Guinea; two are endemic to the Phillipines. Only one species is widely distributed
in S. E. Asia. In the present paper, the genus is divided into two sections and two
series based on the number of stamens and the characteristics of the ovary. One spe-
cies is described as new. 相似文献

The popularity of mobile devices has encouraged the advance of ubiquitous learning, in which students are situated in a real‐world learning environment with support from the digital world via the use of mobile, wireless communications, or even sensing technologies. Most of the ubiquitous learning systems are implemented with high‐cost sensing devices for detecting the locations or behaviours of learners; moreover, these systems mainly focus on providing learning guidance or learning materials, while facilities for supporting mutual help among students are usually ignored. In this study, we propose a context‐aware ubiquitous learning platform (CULP) which uses low‐cost cell phones with embedded cameras and Internet service to support ubiquitous learning. CULP is able to provide instant support for learners in the ubiquitous learning activity; that is, learners can receive help from the right people via the hints given by the learning system when they encounter problems during their learning activities. The experimental results of a Personal Computer‐Assembling course show that, with the assistance of the new learning platform, both the learning efficiency and the learning achievement of the students were significantly improved. 相似文献

Lectures are often thought of in terms of information transfer: students (do not) “get” or “construct meaning of” what physics
professors (lecturers) say and the notes they put on the chalkboard (overhead). But this information transfer view does not
explain, for example, why students have a clear sense of understanding while they sit in a lecture and their subsequent experiences
of failure to understand their own lecture notes or textbooks while preparing for an exam. Based on a decade of studies on
the embodied nature of science lectures, the purpose of this article is to articulate and exemplify a different way of understanding
physics lectures. We exhibit how there is more to lectures than the talk plus notes. This informational “more” may explain
(part of) the gap between students’ participative understanding that exists in the situation where they sit in the lecture
on the one hand and the one where they study for an exam from their lecture notes on the other. Our results suggest that in
lectures, concepts are heterogeneous performances in which meaning is synonymous with the synergistic and irreducible transactions of many different communicative modes, including
gestures, body movements, body positions, prosody, and so forth. 相似文献
