The paradox of trust in online collaborative groups   总被引:1,自引:1,他引:0  
Open and sustained discussions in heterogeneous collaborative online groups should provide opportunities for adults to reshape their thinking, deeply understand the subject content, and have their voices heard and respected. These opportunities turn on trust. The ability to trust thoughts that are different from their own is influenced by the learners’ ability to be open about their beliefs and to develop healthy self–other relationships within their small groups. These issues are examined through a qualitative phenomenographic perspective of the stories of the students enrolled in two online adult learning classes utilizing a problem‐based and collaborative pedagogy. The findings indicate that group members import trust issues into the group, which then become issues for the group‐as‐a‐whole. To resolve these issues, the groups engage in several evading behaviors to avoid the types of discussion necessary to fully deal with the difference and resolve the trust issues.  相似文献

Eighteen Long-Evans rats were exposed to a MULT VT 30-sec EXT schedule of water presentations. The EXT schedule was signaled by a 2500-Hz, 70-dB tone. Mean number of bites of a plastic target during atone (S?) increased across sessions, whereas the mean number of target bites during the VT component signaled byno tone (S+) decreased across sessions. Changing the multiple schedule to MULT EXT EXT produced a decrease in target bites during the tone. Reinstating the original MULT VT 30-sec EXT schedule produced an increase in number of target bites during the tone (S?). Changing the multiple schedule to VT 30-sec VT 30-sec produced a decrease in target bites during the tone. The results indicate that target biting in rats increases in the presence of the exteroceptive tone (S?) of the MULT VT 30-sec EXT schedule, and that target biting during the tone varies directly with the negative correlation between tone and water presentations.  相似文献

ABSTRACT

Since Idaho State University Libraries’ implementation and promotion of EBSCO Discovery Service (EDS) in 2014, its electronic resources team continues to troubleshoot seamless content discovery for library patrons. But nothing prepared us for the kind of content issues the Library would have to deal with on a day-to-day basis. This report discusses ways of managing content in EDS to improve discovery of resources, including linking issues to ClinicalKey records and dealing with “bound with” local catalog records. It also addresses obstacles and solutions, as well as the authors’ experience working with EBSCO Support.  相似文献

This paper presents the results of a study designed to examine the effects of distance delivery on student performance and classroom interactions in an upper level science (Histology) course. Outcomes were assessed by comparing performance on content pre- and posttests for students enrolled in on-campus and on-line sections of the same course. Interactions were classified according to initiator, topic, and Bloom's taxonomy level for content interactions. The resulting patterns were analyzed to compare behaviors in different settings. It was found that although the groups were indistinguishable in content knowledge at the outset of the study, by the end of the semester, students in the on-line group significantly out-performed their peers in the on-campus section. The on-line settings had a greater proportion of high-level interactions (according to Bloom's taxonomy) than the on-campus setting.  相似文献

To obtain benefits in the provision of public services, managers of public organizations have considerably increased the adoption of artificial intelligence (AI) systems. However, research on AI is still scarce, and the advance of this technology in the public sector, as well as the applications and results of this strategy, need to be systematized. With this goal in mind, this paper examines research related to AI as applied to the public sector. A review of the literature covering articles available in five research databases was completed using the PRISMA protocol for literature reviews. The search process yielded 59 articles within the scope of the study out of a total of 1682 studies. Results show a growing trend of interest in AI in the public sector, with India and the US as the most active countries. General public service, economic affairs, and environmental protection are the functions of government with the most studies related to AI. The Artificial Neural Networks (ANN) technique is the most recurrent in the investigated studies and was pointed out as a technique that provides positive results in several areas of its application. A research framework for AI solutions for the public sector is presented, where it is demonstrated that policies and ethical implications of the use of AI permeate all layers of application of this technology and the solutions can generate value for functions of government. However, for this, a prior debate with society about the use of AI in the public sector is recommended.  相似文献

The purpose of this investigation was twofold: (a) to compare most and least economical runners on use of attentional strategies and (b) to determine whether the least economical runners within the subject sample could improve running economy (RE) with the use of an active associative (relaxation) attentional strategy. Subjects (N = 36) completed an initial assessment of attentional style and RE; then the 12 least economical runners ran in each of three laboratory sessions using control, passive associative, and active associative attentional strategies. Results showed that the most economical and least economical runners did not differ in associative style use. The most economical runners, however, reported less dissociation use and more use of relaxation than did the least economical runners. No significant physiological or psychological changes were associated with any of the three attentional strategy conditions. The findings are related to possible differences in how most and least economical runners use associative strategies.  相似文献

Articles concerning computer law abound. Institutions of higher learning have produced lengthy documents addressing computer ethics on campus, and several organizations have printed materials to educate the public. Are these efforts working? Are the ethics and values in the business world and in the education world the same? Several scenarios are examined in investigating these questions.  相似文献

The study investigates the preschool readiness of moderately preterm children and, in particular, the likely presence of learning disabilities at preschool age. Its theoretical model detects linguistic comprehension and expression; memory-related metacognition and cognition skills; orientation and motor coordination skills; premathematics and preliteracy ones. The research project involved an experimental group made up of 55 moderately preterm children (mean age?=?62 months, mean gestational age?=?34.6 weeks), without any clinical neonatal complications, and low birth weight (M?=?2,100 g, SD?=?350 g); a control group made up of 55 full-term children without pre- and perinatal complications. The children’s primary school reference teachers were given a questionnaire (Observative Questionnaire for Early Identification of Learning Disabilities), which was aimed at identifying any likely social and cognitive skill deficits at preschool age. The data, submitted to nonparametric univariate variance, show how scores of moderately preterm children in the metacognition [U (n1 e?n2?=?55)?=?35, p?=?0.04, r?=?0.49] are statistically lower, other cognitive skills (memory, orientation, and visual–motor coordination) [U (n1?e?n2?=?55)?=?32, p?=?0.02, r?=?0.45], premathematics [U (n1?e?n2?=?55)?=?32, p?=?0.02, r?=?0.44], and the total score [U (n1?e?n2?=?55)?=?31, p?=?0.02, r?=?0.12]. Such data would seem to suggest the need for hypothesizing preventive training and educational paths as a prerequisite for the development of the school abilities.  相似文献
