【摘要】 近年来，我国围绕素质教育的开展，掀起了教学改革的浪潮。较为科学的教学改革思想是：充分了解学生获取知识的信息加工过程，根据学生认知过程和特点科学地设计教材和教法，通过启发式的方法引导学生有效地获取知识，发展认知技能。本着这一教学改革的思想，朱新明教授和Simon教授，进行10多年的协作研究提出了示例演练教学法。示例演练教学法将“例中学”和“做中学”有机地结合起来，以“示例演练”作为基本的学习形式，是一种有利于素质教育的教学模式。 本课题在前人对示例演练教学法的研究基础上，深入理解和分析了示例演练教学法。紧紧抓住示例演练教学法符合学生认知规律和适合不同层次学生的两大优点，弥补网络教学中传统教材电子化、缺乏教学策略的不足，尝试着将示例演练教学法应用于网络教学中，以达到两个目的： 1、解决目前网络教学存在的“书本搬家”的问题，使网络教学开展得更好。 2、变传统的“一刀切”的课堂教学模式为分类推进、共同进步，让不同层次的学生在网上示例演练教学环境下都以自己最好的状态进行学习，将自己的潜能最大程度地发挥，进行最有效地学习。 基于以上两个目的，本课题探索了网上示例演练教学模式，从知识库、学生模型、教师模型、支持系统四个方面入手，提出了网上示例演练教学系统模型。并据此模型，选择初中一年级代数为教学内容，设计开发了一个网上示例演练教学系统实例——网上示例演练教学学苑。更多还原

【Abstract】 Recently, our country have been prevailing the trend of the reform of instruction focusing on the quality education. The more scientific principal of the reform should be as follows: Firstly, the process of information for assimilation of knowledge must be clearly find out. Secondly, Developmental method which instructs students’ efficient gain for knowledge and the development for cognitional skills is rooted on these: the students’ characteristics of cognitional process and scientific design for textbooks and instruction method. Based on the principle of the above reform of instruction, Prof. ZhuXinMing and Prof. Simon put up with Theory of Learning From Examples And Through Problem Solving after ten years’ corporative research. The instruction based on this theory systematically combine the "learning from examples" and "learning by doing". The fundamental form of the study model guided by the theory of learning from examples and solving by problems benefits the quality education.This subject deeply understand and analyse the Theory Of Learning From Examples And Through Problem Solving based on the former research for it. One of the two superiorities is the theory’s accordance with students’ cognitional rule, the other the theory’s fitness for different level of students. This theory also crack the inferiority of the electronic edition of the traditional web-based instruction textbooks and the measures. Further, the theory’s application to the web-based instruction is tried. All these aimed at the two goals below:1. Solv ing the problem of "move of books" which exists in current web-based instruction and making the web-based instruction better.2. The traditional instruction model of "one knife’s cutting" are evolved to classified advance and entire progress. This evolve promotes students in different level study most efficiently by the web-based Learning From Examples And Through Problem Solving, and exert the greatest potential with the best situation.Based on the above two goals, this subject delve into the model of the web-based Learning From Examples And Through Problem Solving. From theknowledge-database, students’ model - teachers’ model and supportive system , the system model of the web-based Learning From Examples And Through Problem Solving come into being .On the basis of the model, an applied system called "the study gardening of the web-based Learning From Examples And Through Problem Solving are put up with choosing the algebra in the first-grade junior high school.更多还原
