Abstract :
In this paper,we present the comprehensive version of CSIEC (Computer Simulation
in Educational Communication), an interactive web-based human–
computer dialogue system with natural language for English instruction, and
its tentative application and evaluation in English education. First, we briefly
introduce the motivation for this project, survey the related works and illustrate
the system structure with flow diagram. Then we describe its pedagogical
functions, especially free chatting and chatting on a given topic.We summarise
the free Internet usage within 6 months and introduce its integration into
English classrooms, as well as the formal evaluation results of the integration.
The evaluation findings show that the chatting function has been improved
and fully used by the users, and the application of the CSIEC system in English
instruction can motivate the learners to use English and enhance their learning
process. Lastly,we discuss the application-driven approach of system development
and draw some conclusions for future improvement.
