A Web-Based Learning Platform Based on Super Learning Objects: “Chao Zi” Ning Kang, Tao Wang, Shengquan Yu and Heping Hao Educational New Media Learning Supermarket, China Education Television (CETV), Beijing, China hao.heping@gmail.com Abstract. This paper presents a Web-Based Learning Platform based on a super learning object (Chao Zi) with these unique features: self contained teaching objects, openness, capability of aggregation and evolution. Because the learning units of this platform are small and stand alone, it provides flexibility for both learners and authors. As a tool for personal construction of knowledge, it provides a learning environment in which learners can choose any Chao Zi to study on, to write notes, to make links with other Chao Zi and to communicate with other learners who study on the same one. All related Chao Zi, according to their semantic associations, are presented to learners. All learner-generated information related to Chao Zi contributes to the evolution of Chao Zi, which exemplifies the power of learning networks and distributed learning. This paper addresses three major platform components: Chao Zi, the learning environment of Chao Zi, and the service interface between both parts. Keywords: Web based Learning platform; Learning Object; e-Learning; Introduction In the traditional web-based learning platform, educators have to build up the whole e-course for their online teaching. Learners have to register for the whole course and study chapter by chapter, according to the course pace. There are several weaknesses in this pattern. First, it lacks flexibility for both teachers and learners. For teachers, it is hard to renew learning content because too many procedures need to be followed according to the process of building an online course. Some students, especially those adult learners or professionals who already know part of what the course covers, may like to focus on certain knowledge or skills according to their needs, based on their own structure of knowledge, rather than go through all of the chapters. Second, in the traditional approach, educators take all responsibilities to develop an online course; learners have no chance to make changes to the course content or make their own contributions. In order to increase the flexibility for teachers and learners, to facilitate the learners’ process of construction of knowledge, and to leverage the learning via a social learning network, we designed and implemented a Web-based learning platform based on the Chao Zi mechanism. In Chinese, Chao means super; Zi refers to knowledgeable people such as Kong Zi(Confucius) or Lao Zi (Lao Tzu), who are well-known intellectual people in Chinese history, Zi also means elements of entity. Chao Zi not only shares the same features as learning objects, such as being sharable, scalable, reusable, and adaptable, but also has unique ones: self contained teaching object, openness, capability of aggregation and evolution. As a self-contained teaching object, Chao Zi is a small,
