This study explores science communication on Twitter by investigating a sample of tweets referring to academic papers in five different scientific fields. The specifications of science communicators on Twitter, the characteristics of those who initiate actions (by tweeting), the extent and quality of reactions (retweeting), individual and group interactions, and the distribution of tweets across types of engagement in the process of science communication (i.e., dissemination, consultation, and evaluation) were explored. A broad array of actors is involved in the communication of science on Twitter, with individual citizens and individual researchers playing an important role. In principle, this is promising for creating direct interaction, which can be difficult through more traditional mass media. The vast majority of communication activities regarding academic papers is undigested dissemination with almost no sign of debate, contestation, or collective reflection. Another general finding of this study is that bot accounts play a major role in the science communication landscape on Twitter. 相似文献

In this paper, we focus on understanding the critical role of everyday citizen in planning and policy-related issues in their city enabled by the newly emerging technological platforms such as mobile-based application and internet-based participatory platforms. The interest and capability of citizens to use and benefit from such online platforms that facilitate urban planning has grown in recent times, which makes it important to study the nature of these platforms and civic engagement that is facilitated through them. We study three such platforms and provide policy recommendations to urban planners based on our analyses of the platforms. 相似文献

In sub-Saharan Africa, where there is limited financial and human capital, it is important to examine how social relationships may serve to promote or undermine human capital formation. However, little is known about the contributions of social relations to human capital development, especially in terms of academic achievement in Africa. This study examined how variations in key aspects of social relations among teachers; between teachers and students; between principals, teachers, parents and students affect achievement in mathematics among sixth graders in 70 schools in six districts in Kenya. We modeled mathematics achievement as a function of measures of social perception and support while adjusting for school-, classroom- and student level background characteristics. We found that net of teacher subject knowledge and background characteristics, teachers who display commitment to teaching by always correcting homework and keeping students engaged during math lessons had their students performing better. Teacher absenteeism and lack of interest in teaching were negatively associated with performance in math. Lack of parental involvement in the classroom also had negative effects on grades. At the school level, the level of engagement of the principal, measured by supervision of teachers and good interpersonal interactions with parents had positive effects on math achievement. Schools where parents provided material and financial support had better grades, while student delinquency and absenteeism negatively affected grades. 相似文献

Teachers' perception of changes to their teaching practice, with respect to digital technology use in secondary school mathematics, during their participation in a research project are reported. Two case studies are presented of teacher perspectives illustrative of the range of perceived changes teachers made to their practice and positions along the ‘path of change’ during their participation in the project. Participating in a project supportive of teacher change and resulting in perception of substantial change was necessary, but not sufficient, to meet the goal of transformative use of digital technologies to increase the level of cognitive demand experienced by students. 相似文献

This study examined pre-service primary teachers' perspectives on teaching and learning experiences within college-based courses in ‘practical’ subject areas within a teacher education programme. Following three individual lectures (one each in art, music and physical education), pre-service teachers (n=11) participated in focus group interviews sharing their perspectives on the teaching and learning experiences. These data were analysed thematically and supported by teacher educators' (n=3) planning and reflection documentation. Although the problematic nature of the ‘practical’ suggests appeal and peril of the ‘practical’, the important nature of negotiating the ‘practical’ to enhance student learning is apparent. Students emphasised the value of practical engagement and expressed a strong preference for working in groups to create a safe learning environment to develop confidence and competence. These insights suggest key aspects of a pedagogy of teacher education in these ‘practical’ areas. The importance of being aware of and, in some cases, challenging student perspectives on how they learn best in these curricular areas is discussed. 相似文献
