The Essential Features of Technology and Technology Education: A Conceptual Framework for the Development of OBE (Outcomes Based Education) Related Programmes in Technology Education

It appears that programme development in technology education is emerging from an atheoretical perspective. This could be attributed to the absence/neglect of conceptual frameworks (philosophical underpinning) in the development of programmes in technology education. This article explores the role of the content dimension of the 'essential features' of technology and technology education in OBE (Outcomes Based Education) related programme development. An instructional programme was developed using criteria derived from the essential features of technology and technology education. In order to gauge learners' experience, in relation to these essential features, a qualitative case study involving 20 learners was undertaken at a College of Education. Engagement with theprogramme proved to be an empowering experience for the learners who had hitherto not had the opportunity to experience a formal programme in technology education. Although it could not be proved conclusively that cognitive development had occurred, positive inter-dependence,shared responsibility, social skills and enhanced learning were evident. The study has shown that criteria derived from the 'essential features' of technology and technology education could serve as a reliable yardstick to measure the extent of learning in relation to these essential features     

The Returns to Education: Microeconomics

In this paper we focus on education as a private decision to invest in "human capital" and the estimation of the rate of return to that private investment. While the literature is replete with studies that estimate the rate of return using regression methods where the estimated return is obtained as the coefficient on a years of education variable in a log wage equation that contains controls for work experience and other individual characteristics, the issue is surrounded with difficulties. We outline the theoretical arguments underpinning the empirical developments and show that the evidence on private returns to the individual is compelling. Despite some of these issues surrounding the estimation of the return to schooling, our evidence, based on estimates from a variety of datasets and specifications, is that there is an unambiguously positive effect on the earnings of an individual from participation in education. Moreover, the size of the effect seems large relative to the returns on other investments.     

Introducing Time‐to‐Educate in a Job‐Search Model

Transition patterns from school to work differ considerably across OECD countries. Some countries exhibit high youth unemployment rates, which can be considered an indicator of the difficulty facing young people trying to integrate into the labour market. At the same time, education is a time‐consuming process, and enrolment and dropout decisions depend on expected duration of studies as well as on job prospects with and without completed degrees. One way to model entry into the labour market is by means of job‐search models, where the job arrival hazard is a key parameter in capturing the ease or difficulty in finding a job. Standard models of job search and education assume that skills can be upgraded instantaneously (and mostly in the form of on‐the‐job training) at a fixed cost. This paper models education as a time‐consuming process, a concept which we call time‐to‐educate, during which an individual faces the trade‐off between continuing education and taking up a job.

全面理解人力资本的经济价值——教育经济学与培训经济学的融合

教育经济学不应只是正规学校教育的经济学,在终身学习的理念下,正规学校教育的结束并不意味着学习步伐的停滞和人力资本投资的终结。教育经济学未来拓展的路径,除了理论基础上的"外延式"发展外,还可以在原有的人力资本理论框架内走一条"内涵式"发展的道路,即强调综合考察人力资本投资的多种途径,特别是教育和培训这两种最主要的人力资本投资形式,让教育经济学走出正规学校教育经济学的固有领地,团结在人力资本理论的名义下,与培训经济学融合,走向人力资源开发研究的广阔天地,惟其如此,才能全面、深入地研究人力资本的经济价值及其实现机制。     

大学生人文素质的疏离与重建

人类创造的全部文化 ,包括科技和人文两部分。他们相辅相成 ,共同促进人类的发展与进步。可如今高等教育的现实却是 ,科学技术日益受到崇拜 ,而人文素质教育则逐渐疏离。在更加强调“以德治国”的今天 ,大学教育不应是科技与人文的分离 ,而应是二者的渐趋融合 ,正确认识科学技术的作用与限度 ,关注和营造人情化的生活世界

国家助学贷款：问题与建议

1996年高校招生实行并轨 ,高等教育收费制度的改革已日趋明朗 ,随着扩大招生、收费制度的改革 ,迎面而来的是逐年增多的贫困生 ,为了扩大教育消费、为了不让贫困生辍学 ,政府出台了国家助学贷款政策。实施几年来 ,显现出诸多问题 ,给全面落实带来了困难。目前国家助学贷款在重点院校进展顺利 ,而在普通院校及中小型院校进展缓慢 ,必须加以研究与解决
