智能化时代传统媒介新闻理念的演进与方法创新     

刘坚 《传媒观察》2020,(5):5-11,F0002

在新闻智能化传播的环境下,传统媒介的新闻信息资源理念发生变化,智能算法成为新闻信息资源获取和开发的重要手段。智能化传播的新闻信息价值判断,建构了新闻事实信息-社会数据信息-用户需求信息三位一体的新闻信息价值确认系统,体现了智能化新闻信息价值理念的特殊追求。新闻信息生产流程中人工智能系统与新闻传播者形成特殊的生产关系,新闻信息生产理念强调人机协作与共处,由此产生新闻报道视野和新闻产品形态的变化。智能化的新闻发布机制,促进了新闻信息的多渠道推送和分散化传播,也有力推动了传统媒介新闻信息传播理念的智能化转变。  相似文献

Separated and integrated perspectives on environmental,economic, and social dimensions – an investigation of student views on sustainable development     

Teresa Berglund  Niklas Gericke 《Environmental Education Research》2016,22(8):1115-1138

The sustainable development (SD) concept is based on the idea that economic and social development should be linked to the environment. However, controversies about various associated issues often arise due to the differences in protagonists’ viewpoints, depending partly on whether they focus mainly on environmental, economic, or social dimensions and partly on ideological stances related (for instance) to the optimal ways of promoting economic growth and social justice. This study investigates views of 638 Swedish upper secondary students who responded to a questionnaire probing their views of SD from two perspectives. In the first, the dimensions were separately introduced, so the respondents only had to consider one dimension at a time. In the second, the dimensions were introduced in an integrated fashion, so the respondents had to consider effects related to all three dimensions. The results strongly indicate that the students’ views and priorities concerning the dimensions depend on both the perspective and the context. Implications for teaching and learning are discussed.  相似文献   

The scholarship of teaching: A comparison of conceptions held by experts and regular academic staff     

Carolin Kreber 《Higher Education》2003,46(1):93-121

Over the past decade the scholarship ofteaching has received considerable attention inthe higher education literature as a reactionto the widely cited Carnegie Foundation'sreport ``Scholarship Reconsidered'; however, theconcept has remained devoid of a unifieddefinition. A recent Delphi study conductedwith a selective group of scholars whoseexpertise lies in the area of universityteaching and learning indicated the extent towhich these ``experts' agreed with each other onimportant features and unresolved issues theyassociate with the scholarship of teaching. Building on the results of the Delphi study,the present article discusses the results of asecond survey comparing these ``experts' 'conceptions with those of a larger group ofscholars whose expertise lies in a differentacademic field (``regular academic staff'), inorder to identify the similarities anddifferences in the conceptions of thescholarship of teaching held by each of the twogroups. While regular academic staff werefound to associate the scholarship of teachingmore with good or effectiveteaching ``experts' pointed to notions such aspeer review and scholarly standards. Thediscussion of the results focuses on the notionof consensus reached within and betweenthe two groups. It is argued that in order topromote changes in policy with respect to whatis to count as scholarship, identifying andreporting ``experts' ' conceptions, thoughclearly necessary for promoting moreenlightened discussions on the issue, willremain insufficient. Policy change in academeis more likely to ensue as a result of thewider academic community reaching consensus onthe meaning, and nature, of the scholarship ofteaching. The wider academic community includes``experts', as well as colleagues in departmentsand disciplinary associations. The articleconcludes by exploring the notion of consensusthrough the lens of critical social theory.  相似文献   

Mapping the knowledge structure exhibited by a cohort of students based on their understanding of how a galvanic cell produces energy          下载免费PDF全文

Adrian Sin Loy Loh  R. Subramaniam 《科学教学研究杂志》2018,55(6):777-809

This study evaluates the use of an open‐ended question to determine students' knowledge structure on the topic of galvanic cells. The open‐ended question was developed and administered to 163 Grade 10 students who had earlier completed a course on electrochemistry. Students' responses were marked as well as coded on the basis of the fields identified from their responses. This was then evaluated statistically to determine the collective knowledge structure of the sample of students. The knowledge structure thus mapped contains both canonical concepts and alternative conceptions (ACs). An important finding emerging from this study is that instructors need to focus student's attention on the dynamic processes involving electrons and ions during the operation of galvanic cells. In order for students to fully understand how a galvanic cell operates, they need to see the whole picture. There are three critical components that lead to students' understanding of how an oxidation–reduction reaction can generate energy and how a circuit is complete: transfer of electrons during oxidation–reduction half‐reactions, flow of electrons within metals, and migration of ions in solution. Also, we found that it is possible for students to use correct chemistry concepts in an incorrect way by establishing linkages among these in an inappropriate manner. We reiterate that apart from evaluating students' ACs, it is also important to evaluate the links between the concepts and conceptions present in students' knowledge structure so that teaching can be made more effective.  相似文献   

Trainee teachers' conceptions of teaching and learning,classroom layout and exam design     

Fernando Dome´nech Betoret 《Educational studies》2004,30(4):355-372

The objective of this study centres on identifying and classifying the conceptions of teaching and learning held by future secondary school teachers, and on analysing the relationship between these conceptions and the way classroom space is organized and exams are designed. The test instruments used were applied to a sample of 138 graduates, who were all following the Pedagogical Aptitude Course (CAP) during the academic year 2002/03. Results show that the more traditional teaching/learning models are related to a more vertical classroom layout. Significant correlations between beliefs and exam demands were also found.  相似文献

Teaching Undergraduate Mathematics on the Internet     

Johann?EngelbrechtEmail author  Ansie?Harding 《Educational Studies in Mathematics》2005,60(2):253-266

This is Part 2 of a two-part study of how APOS theory may be used to provide cognitive explanations of how students and mathematicians might think about the concept of infinity. We discuss infinite processes, describe how the mental mechanisms of interiorization and encapsulation can be used to conceive of an infinite process as a completed totality, explain the relationship between infinite processes and the objects that may result from them, and apply our analyses to certain mathematical issues related to infinity.  相似文献   

Explanations of attitudes to change: Colombian mathematics teachers’ conceptions of the crucial determinants of their teaching practices of beginning algebra   总被引：1，自引：0，他引：1  

Cecilia Agudelo-Valderrama  Barbara Clarke  Alan J. Bishop 《Journal of Mathematics Teacher Education》2007,10(2):69-93

This article arises from a study whose overall purpose was to investigate the relationship between Colombian mathematics teachers’ conceptions of beginning algebra and their conceptions of their own teaching practices. The teachers’ understandings of their teaching practices were explored with a view to unravelling their conceptions of change in their teaching. Focusing on the perspectives of teachers afforded opportunities that exposed the powerful role that the teachers’ conceptions of social/institutional factors of teaching played in their conceptions of their practices. The degree to which the teachers attributed these (external) factors as crucial reasons for what they do in their teaching was the basis of a categorisation of their conceptions of the crucial determinants of their teaching practices into three types. The findings are particularly relevant to our understanding of the stability of mathematics teaching approaches in the Colombian context but have likely implications for a range of international education contexts. Specific implications for the development of the research into teachers’ conceptions of mathematics and its teaching, and for teacher education programmes are presented.
