远程教育与社会主义农新村建设

现代远程教育不仅在开展农民的文化教育与技能培训、构建农村学习型社会、建设社会主义新农村方面有着得天独厚的优势和特色,而且与农民科技文化教育的许多特点、特征与要求相适应、相一致,故能适应和满足其多方面、多层次、多类型、多功能的教育与培训的要求,自身也有着良好的发展前景.     

现代远程教育及其责任伦理构建

本文从现代远程教育所具有的道德性属性出发,分析了当下现代远程教育所面临的道德困境,指出现代远程教育要想在当前建设社会主义和谐社会下肩负起自身的历史使命,实现可持续发展,除了要借助法律和制度的力量来规范自身外,更应该强调自身的道德属性,拒斥功利倾向、工具主义的影响,更应该构筑属于自身的责任伦理.     

Offering Adequate Pedagogical Progression via Mobile Equipments—— Experiment of a French Engineering School

Students may enter our 5-year engineering school in France at two levels ： first and third year. However, due to their quite different backgrounds （ this is especially true for third year students ）, we need to provide newcomers with a 6-week training period during which they follow classes in the fields where they particularly feel weak. Unfortunately, depending on the student＇s background, this is not always possible to bring him/her to the expected level. Another aspect one needs to mention is that these students may not have the same weaknesses in a given field. However, for economical reasons, those classes follow a uniform program as it is not feasible to provide a customized progression. In this paper we discuss how to redesign a mathematics course so as to offer tailored exercise sequencing. Groups of 20 students could then draw their exercises from an intranet database according to their previously completed work, try to solve it by themselves, request additional hints and even ask for some direct help from the teacher. Such a database is currently under development. If it turns out several students stumble against the same difficulty the teacher could show the whole class room how to solve it using the digital projector. This project goes one step further than our initial mobile education project （ 2003 - 2004 ）. Until recently, we had used the equipment in a unique direction, from the instructor toward the students. Here, in this new project we are focusing on the whole loop in order to offer a more adequate （personalized） pedagogical progression ： from the student to the teacher （when the tablet PCs are monitored by the teacher）, and back toward the students （when a direct help is provided by the teacher）.
