| 抄録(和) | Nowadays, Java has been broadly used in societies as a reliable and portable object-oriented programming language. To assist Java programming studies, we have developed a Web-based Java Programming Learning Assistant System (JPLAS). JPLAS provides several types of exercise problems to cover different study levels for students. However, none questions grammar concepts of a source code directly. In this paper, we propose a Grammar-Concept Understanding Problem (GUP) as a new type in JPLAS. A GUP instance gives questions about grammar concepts or behaviors of a code using simple natural language. Each answer can be a number, a word, or a short sentence, whose correctness is marked through string matching with the correct answer. Besides this, we present the algorithm to automatically generate a GUP instance from a given source code by: 1) extracting the registered keywords in the code, 2) selecting the registered question corresponding to each keyword, and 3) finding the data required in the correct answer from the code. For evaluation, we generate 20 GUP instances with a total of 99 questions from simple codes on fundamental Java grammar, and assign them to 100 undergraduate students in a university in Indonesia. The results show that the proposal is effective in finding 13 students among them who do not understand Java programming well and need the care of the teacher. |
