Experimental Study Of Problem-based Learning (pbl) Instructional Design Methods. Network Environment

One of goals of elementary educational reform was "cultivate students ability of collection and disposal information , the ability of obtain new knowledge^ the ability of analyses and resolve problem and the ability of communication and collaborate" in 《Element education course reform program(try stage)》 (2001 documents of ministry of education). Problem-Based Learning (PBL) is such a method that uses problem-solving skills and helps students acquire necessary knowledge and critical thinking skills to solve actual problems. The characteristic and objective of PBL are according with goals of elementary educational reform and learning means which were advocated as Collaborate Learning, Inquisitive Learning and so on. Nowadays, Web-Based PBL become the hotspot and core in the view of researcher. This study discussed mainly the core content and method of PBL instructional design in web environment, and verify, modify, perfect its validity by action research and experimentation.This study is separate into four phases: literature research theory study, experiment research and evaluation. This paper analysis the similarities and differences compared with Web-Based PBL and traditional PBL, and pointed out new ideas in Web-Based PBL. Summarizing the foundation of theory, We put forward the content of Web-Based PBL instructional design should comprise the main two parts: Design of Learning Environment, Design of Learning Activity. The core of Design of Learning Environment is design of problem, including the design of learning objective, learning resource, tools for resolving problem, coach strategy, scaffold strategy. The design of Design of Learning Activity are consisted of putting forward problem context, anglicizing problem, resolving problem and submit , evaluation of scheme to resolve problem. For the sake of the experimentation we designed and created the web-site for PBL, which incarnated the characteristic and require of Web-Based To verified, modified, perfected its validity by action research and experimentation. We selected three school : HengFu Middle school, FangCun JinDao Middle school in Guangzhou and First Middie school of NanHai in FoShan as experience base, and selected the geography of senior high school and the physics of junior highschool as content. In the end of paper ,we settled and analysis the data, pointed out the conclusions of the study flaw and suggestion.From the conclusion of the study we can see: teachers approved of the method of Web-Based PBL instructional design; students are filled with interesting and active in the learning process. The ability of analysis , explore, resolve the problem are improved clearly, The skills and initiative of using resource collaboration learning self-guided learning also are meliorated.
