论文学和艺术对美德、感受和情感教育培养的贡献

宏观教育和道德教育的一些看似合理的论断之间具有种种联系：（1）教育是一种宏观文化知识，而不是狭义的学术或技能培训；（2）我们所认为的教育应包含个人成长的道德诉求；（3）情感发展是这种道德形成的重要组成部分；（4）文学和艺术在这种情感教育中起重要作用。这里的主张是，要更清楚地认识德育与文学艺术的相关性，需要一个正确处理道德生活中认知和情感相互作用的德育观。     

The Cultural Roots of Professional Wisdom: Towards a broader view of teacher expertise

Perhaps the most pressing issue concerning teacher education and training since the end of the Second World War has been that of the role of theory—or principled reflection—in professional expertise. Here, although the main post-war architects of a new educational professionalism clearly envisaged a key role for theory—considering such disciplines as psychology, sociology and philosophy as indispensable for reflective practice—there are nevertheless well-rehearsed difficulties about crediting such disciplines with quite the (applied) role in educational practice of (say) physiology or anatomy in medical practice. This paper argues that while recent developments in professional teacher education and training may have moved on from erstwhile instrumentalist and/or applied science (competence and other) perspectives, there may yet be a case for further progress towards a rather more sophisticated philosophical psychology of teacher knowledge and expertise.     

Opportunities and challenges for campus-based universities in Africa to translate into dual-mode delivery

Abstract

With the growing demand for tertiary education, especially in Africa, the transformation of contact universities to dual-mode institutions is critical. However, conventional universities have had limited success establishing the dual-mode delivery stream. This paper assesses barriers to adoption and implementation of open and distance learning (ODL) in conventional higher education institutions in Cameroon, Kenya and Rwanda by applying a framework on innovation adoption to case studies of ODL in higher education in these countries. This qualitative meta-study shows that the transition to dual-mode is not systematic and that there are various barriers, ranging from national policy and funding; infrastructure, organisational structure and capacity; complexity and cost of ODL; as well as student and staff skills and perceptions, which have impeded adoption. Based on the findings, this paper makes recommendations for implementing ODL in existing conventional universities. Cases of successful transition to dual-mode are provided.     

The dynamic impact characteristics of tennis balls with tennis rackets

The dynamic properties of six types of tennis balls were measured using a force platform and high-speed digital video images of ball impacts on rigidly clamped tennis rackets. It was found that the coefficient of restitution reduced with velocity for impacts on a rigid surface or with a rigidly clamped tennis racket. Pressurized balls had the highest coefficient of restitution, which decreased by 20% when punctured. Pressureless balls had a coefficient of restitution approaching that of a punctured ball at high speeds. The dynamic stiffness of the ball or the ball-racket system increased with velocity and pressurized balls had the highest stiffness, which decreased by 35% when punctured. The characteristics of pressureless balls were shown to be similar to those of punctured balls at high velocity and it was found that lowering the string tension produced a smaller range of stiffness or coefficient of restitution. It was hypothesized that players might consider high ball stiffness to imply a high coefficient of restitution. Plots of coefficient of restitution versus stiffness confirmed the relationship and it was found that, generally, pressurized balls had a higher coefficient of restitution and stiffness than pressureless balls. The players might perceive these parameters through a combination of sound, vibration and perception of ball speed off the racket.     

Teachers' perceptions of technology education: Implications for curriculum innovation

This paper describes research into teachers' perceptions of technology education carried out as part of the Learning in Technology Education Project. Thirty primary and secondary school teachers were interviewed. Secondary teachers interpreted technology education in terms of their subject subcultures as did some primary teachers. The primary teachers were also influenced by current initiatives, outside school interests and teaching programs. Specializations: investigations in science, science and technology education. Specializations: learning theories, history and philosophy of science, chemical education.
