The GLOBE Visualization Project: Using WWW in the Classroom

Though commercial interest in the World Wide Web is growing, the potential uses of the medium as a learning tool are numerous. The GLOBE Visualization Project is one such educational application. We have designed and implemented a WWW-based, user-friendly, language-independent, graphical user interface providing access to visualizations created for GLOBE, a multinational program of education and science. The target users of the system are K–12 students and their teachers from over 1100 schools in 39 countries; other clients include the GLOBE scientific investigators and members of the public internationally. Navigation is intuitive, and employs the metaphors of a Control Panel which changes the image appearing in a Viewscreen. The interface can be learned empirically by persons of all ages regardless of technical expertise or native language; context-sensitive help is provided for users who prefer documentation. The GLOBE Visualization server is on the World Wide Web at URL http://globe.gsfc.nasa.gov/globe/.

Broken Links: The Ephemeral Nature of Educational WWW Hyperlinks

The use of distributed (Internet) resources to enhance both traditional and distance education has caused much excitement in the science education community. However, one of the difficulties with relying on such freely available distributed resources has been the lack of certainty that the resources will be available for students next month, next semester, or next year. We have recently been involved in the development of three graduate-level biochemistry courses designed for high school teachers. Development of these courses relied heavily upon distributed science education resources. As a consequence, they represented a set of authentic science education resources that could be monitored over time to determine their rate of extinction. In total, the three courses contained 515 nonredundant URLs representing either scientific content of science education pedagogy. These have been monitored on a monthly basis during the 14 months since the creation of the courses (August 2000). During this period 85 (16.5%) of the URLs have ceased to function or had their content changed. The most attrition was seen in URLs with the edu, com, and org domain names, in which 17.5, 16.4, and 11% have already become inaccessible.     

试论问题情景式教学与科学思维方法的培养

1999年 12月在南京举办的“3+综合”高考改革研讨会上 ,一位中学校长的发言令我陷入沉思。该校长 92年所执教的两个高三毕业班在化学高考中取得了均分 94的好成绩 ,然而 ,两年后学生返校时 ,他仍将当年的高考试卷给这些学生测试 ,结果平均分只有 16 .6 ,差距之大 ,令人瞠目。该校长在对试卷得分的详细分析后发现 :所得分数主要是与化学思维方法相关的内容 ,具体的知识和运算技巧几乎遗忘殆尽。可见 ,化学教学中如何以学科知识为载体 ,培养学生科学的思维方法 ,应是每一个化学教师值得研究和探索的问题。笔者通过对多年教学实践的反思 ,深深…     

Normal science and the paranormal: The effect of a scientific method course on students' beliefs

A nonequivalent control group design was employed to test the effectiveness of an interdisciplinary course on the scientific method in increasing students' skepticism toward the paranormal. The course explored legitimate methods of scientific inquiry and compared them to faulty, and often fraudulent, methods of pseudosciences. Topics included elementary logic, logical fallacies, statistics, probability, the scientific method, characteristics of pseudosciences, and the prevalence and persistence of pseudoscientific theories and beliefs. Students enrolled in a psychology and law class served as a control group for the “Science and Pseudoscience” class (the treatment group). At the start of the term, students in both groups completed the Belief in the Paranormal Scale (Jones, Russell, and Nickel, 1977) and a measure of beliefs in their own psychic powers. At the end of the semester, students completed these same measures. Results demonstrated that while there were no initial differences between the control and treatment groups in their belief in the paranormal, students in the “Science and Pseudoscience” class demonstrated substantially reduced belief in the paranormal relative to the control class. There were no changes in students' beliefs in their own paranormal powers. Implications for science education and research on teaching thinking are discussed.     

基于WWW技术的教学系统

随着信息高速公路的迅速发展,ＣＡＩ（计算机辅助教学系统）的开发研制也转向了网络化、智能化和多媒体化。本系统采用Ｉｎｔｅｒｎｅｔ的ＷＷＷ技术,如ＨＴＭＬ制作、ＣＧＩ编程、Ｊａｖａ和ＪａｖａＳｃｒｉｐｔ编程、ＧＩＦ８９ａ动画制作、ＶＲＭＬ（虚拟现实）制作等技术,实现了既可用于课堂教学,又可以用于学习者通过网络和通用的浏览器自学、复习、自测、质疑以及在网上与老师、同学对话或讨论的“模拟电子技术”课程教学系统
