Abstract
With the emergence of information technology, wireless communication and mobile devices are the newest applications in education. The wireless technology enhanced classroom (WiTEC) integrates wireless local area network, mobile learning devices, and client-server architecture to support instruction and learning activities in classroom. This paper introduces the framework of three learning activity levels, namely learning function, learning episode, and learning flow, as the basis to design and develop an integrated system to support various kinds of learning activities in WiTEC. A teacher can use the system to form new learning flows before class and to implement them in class. A two-stage evaluation was conducted in three elementary classes to investigate the usability and feasibility of the proposed system. The participated teachers indicated that the integrity mechanism of three learning activity levels eases the burden of preparing, implementing, and reviewing instruction and learning.
