The educational technology has the very intense practical orientation, but because this practical orientation is too powerful, it causes the researchers of educational technology can be unable to stop to think some basic theory questions, and be far away from asking educational technology some ultimate questions about educational technology. So it has caused that afer semicentennial developing educational technology still exit some questions such as confusing, the reality helpless, deficient theory, although it has obtained many encouraging performance, but it is unsuitable that educational technology is the commanding point of education reform and the breach status. Facing these conditions, educational technology needs carry on reviewing and looking up in historical and reality multiple field, needs integrate and conclude for obtained studying results, needs reflect on own level, and need to have the big breakthrough in the discipline elementary theory construction.

教育技术具有非常强的实践价值取向，但这种实践取向的过于强大往往使得教育技术的研究者们无法停下来思考本领域一些基本的理论问题，因此直接导致了教育技术学在经历了半个多世纪的学科建设历程之后，尽管取得了诸多可喜的成绩，但是依旧存在理论与实践研究的诸多问题，这对于面临新技术的发展和世界范围的教育改革浪潮而给予的教育技术作为教育改革的制高点和突破口的地位是极不相称的，教育技术学迫切需要在历史与现实的多重视野中进行回顾与前瞻，对已经获得研究成果进行综合和归纳，需要对学科自身进行深层次反思。

Modeling and stability analysis problem of linear switched system are emphasized in this part and main results include:(1) Through investigation in the projection of 〓 on x, where x denotes continuous state vector, a series of sufficient conditions for stability, asymptotic stability and unstability of linear switched system's equilibrium in the sense of Lyapunov are achieved. And also, a sufficient and necessary condition for state bounded stability of linear switched system is received.(2) For a class of periodical linear switched system whose switching sets are a group of ordinal lines starting from the original point, it's proved that state bounded stability can be defined by the running characteristic in a single period (3) Based on linear switched system, the concept of linear switched system network is put forward. Linear switched system network is a complex network interconnected by many linear switched systems.
