This paper, first delivered at the 1979 Conference, reviews 25 years of experimental research into production and presentation variables. A number of suggestions are made for continuing research in specific areas and a bibliography of 45 references is appended. 相似文献

This paper examines the basic notions of Ferdinand de Saussure (1857–1913) who was a preeminent figure in the development of linguistics and the foundation of structuralism. It suggests that a key aspect of twentieth century thought has been the growing recognition that the study of language can offer a framework through which we can develop an understanding of our world. It thus proposes that language is fundamental to the process of learning mathematics on every level whether it be through classroom discussion, group exploration, teacher exposition or individual interaction with printed material. Ensuing from this the paper investigates possible mathematical perspectives upon Saussure's ideas and explores what contribution his work can offer to enhance and enrich the interpretive framework through which we observe mathematical activity in the classroom. It takes as an example a mathematical investigation carried out by a group of 12 year old girls and develops the analysis from a Saussurian stance. The paper concludes that language is the medium through which, and in which, mathematical ideas are formed and exchanged. 相似文献

The role of the principal is imperative in creating a school climate that nurtures differences and equality at the same time. Policy and legislation in Ireland dictates the responsibility of school principals in preventing and intervening in issues relating to bullying. The current research investigates the extent to which principals consider the impact of bullying on their students and the strategies they take to combat it in their schools. We consider how principals respond to bullying and what supports they feel are missing for them to adhere to relevant policy. A sample of 918 principals from a range of schools across Ireland completed an online survey. The results demonstrated some positive actions by principals such as the provision of anti-bullying policies. However, they also document areas that need more action such as increased access to counsellors and appointing a specific staff member to deal with and tackle bullying in each school. Guidance from the Department of Education and Skills in Ireland on the development and provision of an anti-bullying programme is called for. Results are discussed in light of the current Anti-Bullying Procedures established by the Department of Education and Skills and the Action Plan for Bullying 2013. 相似文献

The Cooperative Research Centres Program aims to enhance the effectiveness of the overall Australian R&D effort by drawing together researchers from several institutions to create the concentrations of resources which are needed, in many research fields, to keep pace with the rapid scientific and technological progress which is occurring internationally. The Centres link together outstanding groups of researchers, from both the public and private sectors, with the users of research from appropriate industry sectors and other sectors of the economy and provide opportunities for research users to participate actively in the planning and operation of the research activities. The Program was started in 1990. Fifty-two Centres have now been approved across six major R&D and industry sectors representing, when these Centres are fully established, a commitment by the government of some $100 million per year and, from the participants, of some $200 million per year. This constitutes some six percent of the national R&D effort. 相似文献

Child abuse: adolescent records vs. adult recall 总被引:4,自引:1,他引:4
In a follow-up study of incarcerated Connecticut youth, 69 subjects were interviewed during young adulthood. On follow-up, 26 gave histories of abuse discrepant with histories obtained from records and interviews conducted in adolescence. Eleven subjects agreed to an additional clarification interview, at which time they were apprised of the discrepancies. Of these, eight had adolescent records indicating that abuse had occurred but denied abuse during the adult follow-up interview. The remaining three had adolescent records indicating no abuse had ever occurred, but, on follow-up, reported having been abused. The additional clarification interviews revealed that all 11 subjects with discrepant histories had, in fact, been abused. Reasons for these discrepant data and strategies to enhance the investigator's ability to obtain accurate data regarding abuse are discussed. 相似文献

The results of recent studies into the use of the concept mapping heuristic seem to demonstrate that meaningful learning results through its use in science classrooms. While this underscores the need to use more effective instructional strategies in science teaching, the issue of the intervening variable of anxiety in learning and science achievement, and the possible use of a metacognitive strategy in anxiety reduction have not been addressed. This study, therefore, sought to find out if the metacognitive strategy of concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 (30 boys, 21 girls) senior secondary one (grade 10) students participated in this experiment. Two instruments—the Zuckerman Affect Adjective Checklist and the Biology Achievement Test—were used in pre- and posttest administrations to measure the treatment effect on anxiety and achievement, respectively. Findings support the stand that concept mapping is significantly more effective than the traditional/expository teaching strategy in enhancing learning in biology. In addition, it apparently reduces students' anxiety towards the learning of biology. A significant reduction of anxiety was noticed for male subjects. 相似文献
