| The rapid development of computer and network communication technology has offered a more extensive space for technology of computer-assisted instruction. Recently a variety of online examination, teaching, and contest has become an important way in the teaching-support systems. However, these systems are subject to achieve an evaluation for objective topics instead of an effectively automatic evaluation of subjective topics. Therefore, how to realize the automation in evaluation systems is a research hotspot and one of the difficulties in recent years, which will, on the one hand, send students a timely feedback of the results of the in-class exercises, after-school practices of basic courses of programming, the mid-term and final term examinations to promote students'self-training and improve their programming skills; on the other hand, reduce, to some extent, the workload of teachers, increase the work efficiency and help teachers to devote better to teaching.On the basis of the existing supporting systems for basic course teaching in various types of programming and the researches of online evaluation system, with the modern educational theories and technology as foundation , the LAMP as development environment of the software, the double-core CPU as the hardware platform, this thesis carries out the research and design of online evaluation teaching-supporting system on the platform. First, this thesis introduces the existing domestic and foreign supporting systems for basic course teaching in various types of programming and the researches of online evaluation system, and explains the function and impact of the present online evaluation system on various types of programming courses. Second, it carries out a detailed research of online evaluation teaching-support system of programming based on the modern education theories and technology, popular LAMP website framework on Internet and the multi-core CPU hardware platform. Then, it focuses on the design and implementation of on-line evaluation system on a multi-core CPU hardware platform, which will improve the solo-core system and solve the problem of low efficiency in the single-thread or single-process evaluation. Finally, this paper summarizes the major work currently done, discusses the problems in the current system, and makes an outlook for further study and settlement. |
