This study investigated the effects of different teaching and learning methods for statistics for 2 levels of prior knowledge on cognitive load, propositional knowledge, and conceptual understanding. Teaching methods were whether or not to provide students with propositional information, and learning strategies were self-explaining the learning material and explaining in pairs. The results indicate that prior knowledge facilitates propositional knowledge development and leads to differential effects of teaching and learning methods on conceptual understanding: Only low prior knowledge students profit from additional information in the learning task and/or explaining in pairs. An implication of these findings is that low prior knowledge students should be guided into the subject matter by means of working in pairs on learning tasks that comprise additional information. Once students have developed more knowledge of the subject matter, they should be stimulated to work individually on learning tasks that do not comprise additional information.  相似文献

Interdisciplinary project teams on agriculture and environment: A problem-oriented approach     

G.W.J. Barendse  D. van der Hoek 《The Journal of Agricultural Education and Extension》2013,19(3):83-103

Abstract

In a one-year, postgraduate, professional training course an interdisciplinary project approach is taught to prepare disciplinary specialists for interdisciplinary team work. This paper is based on five years of experience with such projects and deals with the conditions necessary to engage successfully in interdisciplinary project teaching. A high degree of organisation, firm guidance at the start of the project, feedback on actual practice from experts, the importance of cyclical working methods, the use of project planning techniques and product-oriented thinking are elements to be stressed. As an illustration a project is presented on environmental policy for a specific target group: greenhouse horticulturists in the province of Zuid-Holland, The Netherlands.  相似文献

Sexual behaviour profiles of HIV-positive youth in the Netherlands     

Linda van der Knaap 《Sex education》2013,13(4):406-420

Young people living with HIV are challenged when it comes to exploring their sexuality. Their sex education is hampered by the fact that their preferences and attitudes towards sexual behaviour are little known about. In this study from the Netherlands, Q-methodology was used to identify sizeable and meaningful sub-groups sharing common attitudes and viewpoints. Thirty of 48 eligible HIV-positive young people aged 12–21 years treated in one of the four Dutch HIV centres rank-ordered 45 statements on the topic. Thereafter, they explained their ranking. By-person factor analysis identified five distinct sexual behaviour profiles (SBPs): (a) safer sex & disclosure to steady partner; (b) motivated by faith and culture; (c) disclosure to good friends, values peer support; (d) conscientious, worries about disclosure and future; (e) self-confident, faith and family are important. Profiles differ in terms of the roles of culture and religion, the influence of family and friends, personal views about disclosure of HIV status, knowing the transmission mode, and viral load. Study results indicate that different approaches to sexual health education are required based on these different orientations. Q-sorts and SBPs may be helpful in discussing sexual behaviour with HIV-positive young people and in developing tailored strategies to meet their interests and needs.  相似文献   

Europe and the United States: the implementation of geographic information systems in secondary education in two contexts   总被引：2，自引：0，他引：2  

Sarah Witham Bednarz  Joop van der Schee 《Technology, Pedagogy and Education》2013,22(2):191-205

Since its inception in the early 1990s, geographic information science and its related technology, geographic information systems (GIS), have diffused slowly into select groups of K‐12 classrooms worldwide. The technology has not been adopted at a rate commensurate with expectations. The purpose of this article is to explore GIS implementation by comparing the variable status of GIS education in pre‐collegiate education in the United States and Europe and factors that appear to play a role in diffusion. The authors use a model of internal and external factors that influence adoption of education innovation as a heuristic to compare and draw conclusions.  相似文献

Military Wives' Stressful Disclosures to Their Deployed Husbands: The Role of Protective Buffering     

Andrea L. Joseph  Tamara D. Afifi 《Journal of Applied Communication Research》2013,41(4):412-434

This study combines the fever model with communication privacy management to examine the conditions under which military wives are likely to disclose their family stressors or engage in protective buffering with their deployed husbands. Military wives (N =105) whose husbands were deployed and who had at least one child completed a web-based survey about the communication of family stressors during deployment. Protective buffering was associated with negative health symptoms, and disclosure was related to marital satisfaction. Wives' perceptions that their husbands were in dangerous situations as well as their perceptions that husbands were supportive of their disclosures were both related to protective buffering and disclosure.  相似文献

Applying Visitor Preference Criteria to Choose Pro‐wildlife Behaviors to Ask of Zoo Visitors     

Liam Smith  Betty Weiler  Amy Smith  Pieter van Dijk 《Curator: The Museum Journal》2012,55(4):453-466

Abstract Many zoos now emphasize that their role in conservation includes influencing the behavior of their visitors for the benefit of wild animals. However, there is limited evidence of behavioral change to support this emphasis; one reason may be that requested behaviors are not viewed favorably by zoo visitors. The purpose of the present study was to involve zoo staff in a process of identifying and prioritizing pro‐wildlife behaviors using a set of criteria that noted what zoo visitors prefer. This was achieved by replicating Smith’s (2009a) study but including visitor‐preferred attributes identified in Smith, Curtis, and van Dijk (2010) . Across several zoos in Australia, 152 staff members participated in seven Nominal Group Technique workshops. Initially over 500 behaviors were identified and prioritized, first by filtering behavior lists, then by participants voting on behaviors. When voting, participants tended to choose behaviors promoting wildlife‐friendly consumerism and donations.  相似文献
