Computer Ability Assisted Assessment System for Large-Scale Heterogeneous Distributed Environments

Network-based computer aided assessment system has played an important role for computer education reform. In this paper, we firstly analyze the problems caused by computer aided assessment system in large-scale heterogeneous distributed environments. Then we give a short introduction of Zhejiang computer grade examination. Next, we mainly present the system of Zhejiang computer grade examination, highlighting the system architecture and design. In addition, the system´s key technologies consisting of are presented in detail in the paper, which consists of online realtime monitoring, intelligent examination evaluation, distributed concurrent processing, supporting heterogeneous environments, and reliable CAA middleware model. Finally we draw a conclusion and present the future work.
