Social influence on endorsement in social Q&A community: Moderating effects of temporal and spatial factors     

《International Journal of Information Management》2021

This study examines the impacts of social influence, which are manifested by popularity and source credibility, on social endorsement in social Q&A community; and how the relationship is impacted by temporal-spatial factors. By collecting panel data from a large platform, the results of an econometric model demonstrate that popularity and source credibility are positively associated with social endorsement. With respect to the moderation effects, the results further show that time distance strengthens the effect of popularity on the social endorsement, but undermines the effect of source credibility; while crowdedness plays the role that strengthens the impact of popularity on the social endorsement, it has no significant moderating effect on the relationship between source credibility and social endorsement. Both theoretical and practical implications are discussed.  相似文献

Role of teacher-related factors and educational resources in science literacy: An international perspective     

《Studies in Educational Evaluation》2020

The study evaluated the relationship among teaching, leadership, teacher certification, student and teacher number related factors, and index of economic, social and cultural status (ESCS), and science literacy from an international comparative perspective. 2015 dataset of the Programme for International Student Assessment for Turkey, Singapore, the United States, Korea, Italy, and Brazil was used. Two-level hierarchical linear models were established for analysis. Results revealed that school ESCS was the best predictor of science literacy across six countries and additionally teacher-related factors came to the forefront of science literacy performance. The study underlined policymakers should focus primarily on policies that increase equity in education. Furthermore, the effectiveness of investments made in factors related to leadership, teacher certification, the number of students and teachers, which contribute very little to science literacy performance, need to be more questioned. Inferences about the findings were discussed in detail, and recommendations for further research were made.  相似文献

Value for learning during this time of transformation: the first-year students’ perspective     

Shalini Dukhan 《高等教育研究与发展》2020,39(1):39-52

ABSTRACT

Formal education was used by the apartheid government to prepare black South Africans for manual labour, thus there was little curricular focus on the development of higher-order cognitive skills. With the abolition of apartheid in 1994, the education system was re-valued and re-evaluated to provide wider access to quality education; the focus of education policies moved towards the development of self-regulation and higher-order cognitive skills for all learners. There is now a generation of learners who have experienced their schooling in the transformed education system, and it would be useful to understand, from their perspective, what they value in their development of learning within the higher education space. This study answers the question ‘Post-apartheid, what learning methods and resources do first-years perceive to be valuable to their learning when they enter university?’ Participants included 344 students taking a Biology course provided to medical science students at a South African university in 2018. Two questionnaires were administered towards the end of a six-week lecture period, responses were evaluated quantitatively and qualitatively. The first survey, comprised of Likert-style questions, was conducted to determine the students’ views on the mechanisms which they used to support their learning. The second questionnaire comprised open-ended questions and focused on the students’ perception of their learning experience in the course. The findings show that there was a significant (p?<?.001) percentage of first-years who thought that rote-learning would suffice for examination preparation at university, and preferred to engage with their peers and the textbook before they engaged with their lecturers when navigating challenging concepts. Schwartz's model of social values is used to show that more needs to be done for the development of higher-order thinking and self-regulation when students enter university, and to mitigate alienation between students and staff.  相似文献   

Professional development on fostering students’ academic language proficiency across the curriculum—A meta-analysis of its impact on teachers’ cognition and teaching practices     

《Teaching and Teacher Education》2020

This meta-analysis aggregates effects from 10 studies evaluating professional development interventions aimed at qualifying in-service teachers to support their students in mastering academic language skills while teaching their respective subject areas. The analysis of a subset of studies revealed a small non-significant weighted training effect on teachers’ cognition (g’ = 0.21, SE = 0.14). An effect aggregation including all studies (with 650 teachers) revealed a medium to large weighted overall effect on teachers’ classroom practices (g’ = 0.71, SE = 0.16). Methodological variables moderated the effect magnitude. Nevertheless, the results suggest professional development is beneficial for improving teachers’ practice.  相似文献

Drivers of information technology choice by individuals     

《International Journal of Information Management》2021

Technology acceptance has spawned considerable research in technology adoption, technology use, and technology switching. However, technology choice—i.e., an individual’s selection of a technology from a set of technologies that support similar tasks—has received limited attention in information systems research. This research was aimed at identifying the drivers of technology choice through a series of activities in two universities, in which students chose an information technology tool from various alternatives to complete the given tasks. A thematic analysis was conducted on the reasons for technology choice reported by 249 students, which yielded 18 technology, user, and environmental drivers that influenced individuals’ technology choice. This study provides insights into the drivers generally applicable for technology choice and drivers applicable in specific contexts. Implications for research and practice are discussed.  相似文献
