农民作为现代农业的主体,提高其文化素质的、现代农业科技知识和技能水平以及市场经营能力,将直接影响到农村经济发展进程和效果。传统的农业科技推广模式与传播途径已经无法满足农村经济发展对科技和劳动力素质的要求。北京农村远程信息服务工程中心在研究分析北京农村居民采用农业科技的行为特征和学习障碍的基础上,率先在全国将现代远程教育技术引入农业科技推广与信息服务工作,建立起以覆盖北京地区为主的农村远程信息服务系统。该文对系统研究应用过程中涉及问题进行分析介绍,以供参考。  相似文献   

Representational Issues in Students Learning About Evaporation     

Russell Tytler  Vaughan Prain  Suzanne Peterson 《Research in Science Education》2007,37(3):313-331

This study draws on recent research on the central role of representation in learning. While there has been considerable research on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced teacher insights into students’ thinking.  相似文献   

Tongan students’ attitudes towards their subjects in new zealand relative to their academic achievement     

Mo’ale Otunuku  Gavin T. L. Brown 《Asia Pacific Education Review》2007,8(1):117-128

Research indicates that affective attitudes such as liking of a subject and confidence in one’s ability within a subject predict academic performance. Generally, immigrant minority students have positive attitudes and often have low academic performance. This study examines the self-efficacy and liking of subjects of New Zealand students and analyses the relationship of those attitudes towards academic performance in mathematics, writing, and reading by self-reported ethnicity. Data were obtained from the norming samples from the Assessment Tools for Teaching and Learning project in New Zealand. Of special interest are the relationships between attitude and performance for Pasifika and Tongan students in New Zealand. Tongan and Pasifika students had positive attitudes, but their mean scores were not significantly different to other ethnic groups except in writing for Tongan students. Tongan and Pasifika students did have lower academic performance than majority and Asian immigrant students in all three subjects. The correlation between liking and self-efficacy was fundamentally zero for Tongan and Pasifika students, while it was weakly positive for majority and Asian immigrant students. Together these results question the power of self-efficacy and liking attitudes to predict academic performance for immigrant students from agrarian or traditional societies. Further, the data suggest that ‘school effects’ are most likely explanations for this relationship, rather than lack of attachment, opposition, or deficiency theories.  相似文献   

Does Student Language Ability Affect the Assessment of Teacher Language Ability?     

David Coniam  Peter Falvey 《Journal of Personnel Evaluation in Education》2002,16(4):269-285

This article arises from an investigation into the classroom language assessment (CLA) component of the Hong Kong English language benchmark test for lower secondary (Grades 7–9) teachers of English as a second language (ESL). After some background to the benchmarking initiative in Hong Kong and to the CLA test, the article describes a small-scale study into the effect of student levels of ability on grades awarded to teachers working in schools with differing ability intakes. In the study, a group of ESL teachers were videotaped teaching ESL classes at two different student ability levels, with the two sets of videos assessed by trained CLA assessors. Results indicate that, although there is some variety in the grade awarded to the two different classes taught, variation in grades may well be attributable to individual teacher performance rather than to external factors such as the ability levels of the students being taught. The grades awarded were generally consistent, irrespective of whether classes of high-ability students or low-ability students were being taught.  相似文献   

建构主义学习环境下师生角色的转变     

徐银燕 《广东技术师范学院学报》2002,(1):99-103

建构主义学习理论发端于皮亚杰的发生认识论。 90年代以后 ,由于多媒体计算机和基于Inter net的网络通讯技术为建构主义学习环境的实现提供了技术支持 ,建构主义学习理论在教育界产生深远的影响。建构主义学习环境的实现使教育模式和教育理念发生了变化 ,教师的角色和学生的角色也随着变化 :教师从传统教学中单一的知识传授者转向学生意义建构的帮助者、协作者、组织者和促进者 ;学生从传统教学中知识的被动接受者转向信息加工的主体和知识意义的积极建构者  相似文献

Private and Public Schooling in Ghana: A Census and Comparative Survey     

James Tooley  Pauline Dixon  Isaac Amuah 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2007,53(4):389-415

A census and survey of schools in the district of Ga, Ghana, explored the nature and extent of private education, and compared inputs to public and private schooling. Three quarters of all schools found were private, with almost as many unregistered private as government schools. Several important differences between registered and unregistered private schools were noted, including age, fee levels charged, teacher salaries and class size. A range of inputs, such as teacher activity, availability of desks, chairs, libraries, toilets and drinking water, were used to compare inputs to government, unregistered and registered private schools. Some conclusions are explored about the potential role for the private sector in helping meet “education for all” targets.  相似文献
