This article reports on a mixed methods study that evaluated the efficacy of a study counselling intervention programme at a South African university. Quantitative data, collected by means of the Learning and Study Strategy Inventory, indicated that the study skills intervention programme brought about statistically significant improvements in participants' study skills profiles. The qualitative findings that were collected from 10 participants served as a contextual lens to develop a more holistic understanding of the quantitative results. It is argued that multidisciplinary collaboration is required to address the heteregenous needs of students within the higher education context.  相似文献

The uncanny valley posits that very human-like robots are unsettling, a phenomenon amply demonstrated in adults but unexplored in children. Two hundred forty 3- to 18-year-olds viewed one of two robots (machine-like or very human-like) and rated their feelings toward (e.g., “Does the robot make you feel weird or happy?”) and perceptions of the robot's capacities (e.g., “Does the robot think for itself?”). Like adults, children older than 9 judged the human-like robot as creepier than the machine-like robot—but younger children did not. Children's perceptions of robots’ mental capacities predicted uncanny feelings: children judge robots to be creepy depending on whether they have human-like minds. The uncanny valley is therefore acquired over development and relates to changing conceptions about robot minds.  相似文献

Longitudinal tracking of 107 three- to-thirteen-year-olds in a cross-sequential design showed a 6-step theory of mind (ToM) sequence identified by a few past cross-sectional studies validly depicted longitudinal ToM development from early to middle childhood for typically developing (TD) children and those with ToM delays owing to deafness or autism. Substantively, all groups showed ToM progress throughout middle childhood. Atypical development was more extended and began and ended at lower levels than for TD children. Yet most children in all groups progressed over the study's mean 1.5 years. Findings help resolve theoretical debates about ToM development for children with and without delay and gain strength and weight via their applicability to three disparate groups varying in ToM timing and sequencing.  相似文献

This paper examines the experiences of undergraduate university students in response to the employment of video podcasts to support learning and teaching about exotic ecosystems. Six, 15–20‐minute podcasts were made accessible to students through a virtual learning environment, either online or to download to mobile technology. The students were free to watch the podcasts whenever and wherever they chose to. The perceived and actual effectiveness of the technology was assessed by written questionnaire, focus groups and summative assessment results. Students agreed that the podcasts were effective in supporting learning and teaching on the course, largely by offering a flexible and visual learning experience. The podcasts were also perceived as a useful resource for revision and assessment, providing visual images that stimulated factual recall and highlighted knowledge gaps. There were no significant differences, however, in examination essay grades comparing cohorts prior to and post adoption of podcasts. The key to improving the student learning experience appears to lie not in adopting new pedagogy, but in reflexively developing the existing pedagogic strategies employed by both teachers and learners. Of primary importance is uniting the individual learning experience of podcasts with group exploration and critical discussion in a collaborative learning framework.  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

In light of the media industry’s growing focus on audience engagement, this article explores how online and offline forms of engagement unfold within journalism, based on a comparative case study of two American public media newsrooms. This study addresses gaps in the literature by (1) examining what engagement means for public media and (2) applying the concept of reciprocal journalism to evaluate the nature of reciprocity (direct, indirect, or sustained) in the give-and-take between journalists and their communities. Drawing on direct observation and in-depth interviews, this article shows how this emerging focus on engagement is driven by public media journalists’ desire to make their relationship with the public more enduring and mutually beneficial. We find that such journalists privilege offline modes of engagement (e.g., listening sessions and partnerships with local organizations) in hopes of building trust and strengthening ties with their community, more so than digital modes of engagement (e.g., social media) that are more directly tied to news publishing. Moreover, this case study reveals that public media organizations, in and through their engagement efforts, are distinguishing between the communities they cover in their reporting and the audiences they reach with their reporting.  相似文献

The paper uses multilevel analysis procedures to examine individual- and group-level learning barriers that have the greatest impact on pupil achievement in Uganda. The data for this study were collected in 2014 among 2711 Grade 6 pupils attending 82 schools in two rural districts of Iganga and Mayuge in Uganda. Data used in this paper are part of a larger study which sought to examine the schooling patterns, as well as the quality of education received by children living in rural settlements in Uganda. Among the learning barriers with the greatest impact on pupil achievement at the individual-level were lack of parental involvement, lack of pre-primary school attendance, grade repetition, and lack of basic learning resources such as writing materials. At the school-level, the barriers with the most impact on pupil achievement were lack of teacher lesson preparedness, lack of teacher-classroom support by subject advisors, distance between school and teachers’ place of residence, lack of basic classroom resources, and whether or not the teacher kept pupil learning progress records. Implications of the findings for policy and practice are outlined.  相似文献

Exosomes, nanosized membrane-bound vesicles released by cells, play roles in cell signaling, immunology, virology, and oncology. Their study, however, has been hampered by difficulty in isolation and quantification due to their size and the complexity of biological samples. Conventional approaches to improved isolation require specialized equipment and extensive sample preparation time. Therefore, isolation and detection methods of exosomes will benefit biological and clinical studies. Here, we report a microfluidic platform for inline exosome isolation and fluorescent detection using inertial manipulation of antibody-coated exosome capture beads from biological fluids.  相似文献
