| Abstract(in English) | We have developed the Web-based Java Programming Learning System (JPLAS) and have used it in Java programming courses. To deal with students on different learning levels, JPLAS has three types of problem functions that have different diffculty, namely element fill-in-blank problems, statement fill-in-blank problems, and code writing problems, which have been implemented by plural students who studied in our group at different years. As a result, the codes for JPLAS have become complex and redundant, which makes further extensions very hard. In this paper, we propose the coding rule so that the whole implementation of JPLAS follows the MVC model, and refactor it based on our proposal. In this rule, we adopt 1) the abstract class for database accesses, 2) the responsibility chain design pattern to implement three types of marking functions, 3) the human interface transition using JSP and Ajax. We compare the number of code files for JPLAS before and after the refactoring, and check the number of additional files required to extend JPLAS to incorporate two new functions, which verifies the effectiveness of our proposal. |
