Can research on science learning and instruction inform standards for science education?

We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper.

高等学校应为我国制造业的快速发展培养更多的专业人才

随着改革开放的不断深入,特别是我国进入WTO后,经济全球化的进程已成为一股不可阻挡的洪流,我国制造业必须努力进取,去适应国际通用的规则和规范的程序.在制造自动化技术方面,我国与国际上发达国家之间的差距还是比较大的,我们只有加快发展步伐,方能逐步赶上世界先进水平.如何从今天的制造大国走向明天的制造强国,这是值得我们深思的问题.作为高等学校,尤其是工科高校,为我国制造业的快速发展培养出更多的、合格的专业人才,这是我们义不容辞的责任.本文从我国制造业的现状出发,通过与国外先进制造技术的比较,找出我国制造业与世界先进水平之间存在的差距,明确今后发展的目标和重点,针对这些目标和重点,确定我们专业人才的培养方向,以及如何采取更为有效的教学手段,源源不断地培养出合格的专门化人才.     

现代教育技术,实施创新教育的有效途径

作为创新教育一部分的教育方法和手段创新以现代教育技术为依托，现代教育技术是创新教育的桥梁，它对创新教育的很多方面产生重要影响，运用现代教育技术是实施创新教育的有效途径。但我们在运用现代教育技术时还要注意到它的两面性。     

基因技术与人的自身改造

摘要基因科学的进展使人类得以在基因的层次上认识和改造人类自身，通过基因技术对人类自身进行改造的美妙前景给人类带来了巨大诱惑，然而由于生命本身的复杂性、科学方法本身的界限以及基因科学与技术本身还原论方法的缺陷，也使人类对自身的改造面临诸多不确定因素和风险。     

Disruptive silence: deepening experiential learning in the absence of technology

Technology plays an integral role in the lives of the majority of the US population. As technology becomes integrated into young people’s lives, questions arise regarding its effects on learning. This exploratory study draws on interviews with students who attend university in the United States to determine how separating students from technology deepens experiential learning. Participants were interviewed following a study abroad course to New Zealand, during which they were disconnected from technologies such as cell phones, the Internet and social media. In the interviews, students discussed their feelings of being disconnected and describe how disconnecting impacted their overall experience. Participants agreed that disconnecting from technology had positive effects on experiential learning and the global experience. Major themes that emerged include students’ enhanced immersion and engagement, the value of disconnection in providing opportunities for personal growth and the difficulty of initial separation from technology as a result of conditioning.

陶瓷工艺课程实践教学新思路

根据陶瓷工艺课程的特点，注重实践教学，合理调配理论与实践教学时数，变“课程实验”为独立的“实验课程”；实验项目以设计性、研究性和综合性实验为主，形成由“基础实验一综合实验一科研与应用实验”的实践教学新体系；既考虑对学生专业基本原理、基本知识和基本实验技能的培养，又能培养学生的创新意识与发现、提出、解决问题的综合能力。
