王桂卿 《化学教学》2005,(1):124-125
许多重大的科学发现不单单是向人们昭示科学家在其专业领域内科学研究成果,更为重要的是科学家向人们提供了一种揭示自然界变化规律的创造性科学方法。高级中学课本《化学》(上科版)将“元素周期律的发现”作为教学内容之一,目的是“通过对元素周期律发展简史的学习,不仅能使我们了解具体的发展过程,更重要的可以从中学到科学研究的一种模式和科学思维的一些方法”。  相似文献

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/.  相似文献

We have developed a tool for the authoring of adaptive CAL courses, called "Dynamic Courseware Generator" (DCG). It generates an individual course according to the learner's goals and previous knowledge, and dynamically adapts the course according to the learner's success in acquiring knowledge. The DCG runs on a WWW server. The learner receives from this server an individualised course targeted to a specified goal. Afterwards, s/he is adaptively guided by the course through a space of teaching materials on the WWW. Unlike other CAL courses on the WWW, a course produced by the DCG is interactive, it tests the learner's knowledge and dynamically adapts to the student's progress. The authoring tool can be used also for collaborative authoring and learning.  相似文献

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.  相似文献
