电视与农村发展问题探讨   总被引：8，自引：0，他引：8  

胡黎虹 《湖南大众传媒职业技术学院学报》2003,3(1):39-41

在市场化和商业化进程中的电视行业中,农村遭遇冷落已是不争的事实。农村需要电视,期待电视,电视却冷落农村甚至背离农村。两者已经成为现代社会中的一个突出矛盾。出现这种现象的原因归结起来主要有三个:一是市场因素的制约,二是电视从业者观念的局限,三是对于收视事实的误读。办好农村电视节目要重点突出,突出特色,加强联合,增强节目的互动性和参与感,还要抓住主要受众群,突出节目的对象性。  相似文献   

Extending expectancy-value theory predictions of achievement and aspirations in science: Dimensional comparison processes and expectancy-by-value interactions     

《Learning and Instruction》2017

Based on TIMSS data (18,047 Grade 8 students from the four OECD countries that collected data for multiple science domains), this study integrated dimensional comparison theory and expectancy-value theory and tested predictions about how self-concept and value are related to achievement and coursework aspirations across four science domains (physics, chemistry, earth science, and biology). First, strong support for social comparisons suggested that high achievement in a particular domain enhance students' motivation in the same domain, which in turn predicted domain-specific aspirations. Particularly, self-concept significantly interacted with value to predict aspirations. Second, in the processes underlying the formation of self-concept and intrinsic value, students tended to engage in negative dimensional comparisons between contrasting domains (physics vs. biology) but positive dimensional comparisons between assimilating domains (physics vs. chemistry). Similar dimensional comparison processes were evident for the effects of self-concept and intrinsic value on aspirations. The results generalized well across all countries.  相似文献   

Becoming a tutor: student scaffolding in a game-based classroom     

Natalia Monjelat  Laura Méndez  Pilar Lacasa 《Technology, Pedagogy and Education》2017,26(3):265-282

Student interaction in school contexts is a topic that has been researched from many different perspectives. However, the role of students as tutors scaffolding other peers is not normally addressed, since studies are usually focused on the teacher. Moreover, considering the many technologies that can support students’ work nowadays, studies describing specific practices are still needed in order to understand the many possibilities and constraints that can emerge from the use of these tools in the field of education. This exploratory case study aims to extend research on scaffolding between students, presenting data from an ethnographic study where a commercial video game was introduced as part of the curricular activities. Analytically, the scaffolding metaphor is the departing point to describe in detail how the scaffolding process took place, focusing on its purposes and on the role of students as tutors. Our findings reveal how students offered mostly procedural scaffoldings, performing tutor functions such as highlighting relevant features, reducing levels of freedom or controlling the frustration. Results highlight that students can perform scaffolds, and this should be considered as part of the classroom design, making this process visible. Moreover, specific features of the video game enhanced these interactions, which should also be considered when designing game learning environments in the future.  相似文献   

WebIntera-classroom: an interaction-aware virtual learning environment for augmenting learning interactions     

Jingjing Chen  Jianliang Xu  Tao Tang  Rongchao Chen 《Interactive Learning Environments》2017,25(6):792-807

Interaction is critical for successful teaching and learning in a virtual learning environment (VLE). This paper presents a web-based interaction-aware VLE – WebIntera-classroom – which aims to augment learning interactions by increasing the learner-to-content and learner-to-instructor interactions. We design a ubiquitous interactive interface that integrates a pen-and-paper interface with a web-based whiteboard to promote effective learner-to-content interactions. We develop a learning analytics tool that instantly shows learners’ learning interactions, with which instructors can supervise learner-to-instructor interactions. We implement a high-granularity Learning Analytics Engine (hgLAE) to broadcast, record and play a lecture recording. The hgLAE identifies hotspots in a lecture recording and raises students’ awareness of the hotspots when they watch the recording. WebIntera-classroom has been deployed in 11 universities in China. The system obtained high satisfaction in the questionnaires (N?=?464) and face-to-face interviews (N?=?60) conducted with the users from China Jiliang University. We compared the students’ performance, respectively, achieved in traditional classroom and in WebIntera-classroom at China Jiliang University during 2012–2013. The result demonstrates that the students could gain performance improvement by using WebIntera-classroom.  相似文献   

Applications of augmented reality-based natural interactive learning in magnetic field instruction     

Su Cai  Feng-Kuang Chiang  Yuchen Sun  Chenglong Lin  Joey J. Lee 《Interactive Learning Environments》2017,25(6):778-791

Educators must address several challenges inherent to the instruction of scientific disciplines such as physics -- expensive or insufficient laboratory equipment, equipment error, difficulty in simulating certain experimental conditions. Augmented reality (AR) can be a promising approach to address these challenges. In this paper, we discuss the design and implementation of an AR and motion-sensing learning technology that teaches magnetic fields in a junior high school physics course. The purpose of this study is to explore the effects of using natural interaction on students’ physics learning and deep understanding compared to traditional learning tools. The 38 eighth graders who participated in this study were assigned to either an experimental group or a control group. Analysis of the results shows that the AR-based motion-sensing software can improve students’ learning attitude and learning outcome. This study provides a case for the application of AR technology in secondary physics education.  相似文献   

From learning to labour to learning for marginality: school segregation and marginalization in Swedish suburbs     

Dennis Beach  Ove Sernhede 《British Journal of Sociology of Education》2011,32(2):257-274

In this article, using data from ethnographic research, we try to present some glimpses of the way education is described as an experience and possibility ‘from below’, by pupils who grow up and study in schools in the most segregated and territorially stigmatized suburbs on the outskirts of our major cities. What we feel they describe is an experience of schooling for surviving the social and economic consequences of curtailed citizenship in a post‐industrial society rather than one of schooling that offers possibilities of integration and full citizenship or social transformation. Our findings have significant policy implications in this respect. Sweden has historically pursued projects aimed at educational inclusion but has recently taken a significant turn toward neo‐liberalism and educational consumerism, since which time various disadvantaged groups have become increasingly concentrated compared with others in under‐achieving schools in an economically threatened public sector. The article discusses some aspects and possible consequences of this development.  相似文献   

Perceived physical competence,enjoyment and effort in same‐sex and coeducational physical education classes     

Minjeong Lyu  Diane L. Gill 《教育心理学》2011,31(2):247-260

Perceived competence is a key motivational determinant of physical activity behaviours in adolescents, and motivational determinants are influenced by the class environment. The purpose of this study was to investigate levels of perceived physical competence, enjoyment and effort in class, focusing on gender and class‐type differences. Participants were 546 adolescents (289 males, 257 females) who were in same‐sex or coeducational physical education classes. The Hierarchical Physical Competence Scale (HPCS) and questionnaire measures of enjoyment and effort in classes were used to investigate students’ perceptions. Results of 2 × 2 multivariate analysis of variance (MANOVA) indicated that students’ perceptions of physical competence, enjoyment and effort in classes differed according to gender and class type, but these differences must be viewed in light of strong interaction effects. That is, female students reported more positive and adaptive perceptions in same‐sex classes and were more affected by class type than were male students.  相似文献   

Students’ experience of synchronous learning in distributed environments     

Anissa R. Stewart  Danielle B. Harlow  Kim DeBacco 《Distance Education》2011,32(3):357-381

This article reports on a two-year ethnographic study of learners participating in multi-site, graduate-level education classes. Classes sometimes met face-to-face in the same physical location; at other times part of the class met physically elsewhere. Yet all were linked through the virtual space. Ethnographic analysis of four data types explored how the instructor and students were able to interact through videoconferencing technologies. Most of the interaction occurred between the local and distance learners by way of cultural guides, local students assigned to host a distance learner through Google Video chat. The distance learners were able to receive real-time attention from the instructor and were able to share differing perspectives that contributed to increased satisfaction in the course. These interactions allowed for a dynamic collaborative effort among a diverse set of actors in the field of education.  相似文献   

从伯克的"语言四维度"看"印象系列"的修辞效果     

张娴静 《怀化学院学报》2011,30(7):98-100

在<语言是象征行动>中,伯克明确提出语言四个基本维度:诗学、逻辑与语法、修辞以及伦理学.这四个维度几乎覆盖了语言的所有范围:诗学语言在富有情感的同时也含有理性的成分;逻辑语言并不仅仅局限于语法及逻辑思维,更应与理性相结合,指导行动;修辞语言贵在用劝说、劝勉的语气达到合作竞争的目的;伦理语言,要求我们真实准确地表达人格品...  相似文献
