Schools, skills and risk 总被引：1，自引：0，他引：1
Skill development involves important choices for individuals and school designers: should individuals and schools specialise, or should they aim for an optimal combination of skills? We analyse this question by employing mean–standard deviation analysis and show how cost structure, benefit structure and risk attitudes jointly determine the optimal investment strategy. With combined data from DOT and CPS, we establish an upward sloping mean–variance opportunity frontier in skills space. 相似文献

One of the modules in the course Food Chemistry at Wageningen University (Wageningen, The Netherlands) focuses on quantitative
problem-solving skills related to chemical reactions. The intended learning outcomes of this module are firstly, to be able
to translate practical food chemistry related problems into mathematical equations and to solve them and secondly, to have
a quantitative understanding of chemical reactions in food. Until 3 years ago the learning situation for this module was inefficient
for both teachers and students. For this learning situation a staff/student ratio of 1/25 was experienced to be insufficient:
the level of student frustration was high and many students could not finish the tasks within the scheduled time. To make
this situation more efficient for both students and teachers and to lower the level of frustration, digital learning material
was designed. The main characteristic of this learning material is that it provides just-in-time information, such as feedback,
hints and links to background information. The material was evaluated in three case studies in a normal educational setting
(n = 22, n = 31, n = 33). The results show that now frustration of students is low, the time in classes is efficiently used, and the staff/student
ratio of 1/25 is indeed sufficient. A staff student ratio of around 1/40 is now regarded as realistic. 相似文献

In December 1994 the Dutch government started several projects concerning the implementation of Information and Communication Technology (ICT) in the educational system. To systematically gather data on the use of ICT in other countries the Aggiornamento survey was started. The aim of the project was to find and describe transferable ‘examples of best‐practice’ on the use of ICT in education by teachers and students. Because of its great importance to the Dutch economy the attention was initially focused on the use of ICT in vocational education. During the project other forms of education were included in the survey. The Aggiornamento‐project used printed and electronic resources as well as working visits to obtain information. The initial project ended in May 1996 with a final public report on the World Wide Web (in Dutch). This article gives an overview of the results of the survey. The project will be continued.
This article explains the rationale, context, activities and the conclusions of the intial project. 相似文献

Building models to describe processes forms an essential part of molecular biology research. However, in molecular biology curricula little attention is generally being paid to the development of this skill. In order to provide students the opportunity to improve their model building skills, we decided to develop a number of digital cases about developmental biology. In these cases the students are guided to build a model according to a method that is based on expert analysis and historical data; they first build a simplified model based on the wild-type only and then they extend this model step by step based on experimental results. After each extension, the biological implications of the extension are evaluated. The first case was evaluated three times during a regular course at Wageningen University, The Netherlands and once at the University of Zurich, Switzerland. The analysis of audiotapes revealed that students did indeed engage in the reasoning processes, which are typical for model building. Furthermore, exam results seem to suggest that working with the case indeed facilitates model building in analogical situations and the students judged working with the case positively. 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
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

A framework for teaching scientific inquiry in upper secondary chemistry education was constructed in a design research consisting of two research cycles. First, in a pilot study a hypothetical framework was enriched in collaboration with five chemistry teachers. Second, a main study in this community of teachers and researchers was conducted on the process of designing teaching scientific inquiry based on the enriched framework. Also, the enactment by five teachers and 80 students (age 17) of a designed inquiry module on “Diffusion: moving particles” was studied. This resulted in a theoretically and practically founded framework for teaching scientific inquiry, in which an iterative cycle of inquiry for students and a student inquiry community are essential. © 2009 Wiley Periodicals, Inc.

We report evidence that university reputation affects wages of bachelors in China. An unconditional difference between a top-100 university and a top 400–500 university of 23% is increased to some 28% by adding controls. Within the top-100 there is no differentiation in pay-off. Self-rated quality of high school, while affecting quality of university attended, has no effect on earnings. 相似文献

在教育经济学研究领域,传统的教育选择研究文献往往假定个体只考虑教育收益,忽视了投资风险的真实存在。已有文献对教育选择行为的预期假定存在较大差异,强加在个体身上的假定可能导致对教育选择行为的不正确推论,而使用个体主观预期数据替代这些假定能更准确地分析个体教育决策行为。采用2007年在北京六所高校所做的"研究生教育态度的调查",利用预期收入、风险数据对北京高校大学生的研究生教育选择问题进行的实证研究发现,预期收入对选择研究生教育有显著影响,而风险对教育选择的影响却不尽相同:收入风险对于教育选择的影响不明显,主观风险对选择研究生教育则有负效应。此外,还发现就业率是大学生决定是否进一步接受教育的重要因素,所学专业就业率越高,选择继续接受研究生教育的愿望越小。上述研究结果暗示,政府相关部门应定期公布劳动力市场数据,便于大学毕业生对收入和就业状况形成合理预期,从而对未来的教育作出理性选择,有效发挥人力资本的作用。 相似文献
