With the quickly development of network technology, the traditional education mode and the studying condition are facing with the serious challenge. The education based on the Web is gradually becoming the trend of future CAI' s development, which breaks through the traditional education' s limitation and grows promptly with the unique superiority.This article is quadrifid. Firstly, it introduces the correlation theory of distance learning. Secondly, it mostly analyzes the theoretic foundation of the learning environment' s designing in distance learning' s network: three learning theories, teaching mode and students' interaction. And how to design the learning environment under that theory, which can adapts to the students themselves' characteristic. Then puts forward the new structure. Thirdly, according to the importance, function, system design, realization, designs and expatiates a course learning and test system of 《 circuitry of simulating electron》 . Lastly makes a conclusion vs the whole article. |
