Abstract (in Japanese) (See Japanese page) 
(in English) To let students study the object-oriented programming of writing program codes without redundancy, we have proposed the code clone elimination problem in Java programming learning assistant system (JPLAS). In this problem, a student is asked to modify the given problem code with code clones into the answer code without them, where the answer code is verified by the unit test on JUnit and the code clone detection test. For this problem, we categorize the four code clone elimination methods: (1) using correct grammar, (2) generating a proper method, (3) generating a proper class, and (4) applying the template method, and prepare the corresponding assignments. The trial application of the simple assignments clarified that the number of solving students rapidly decreased in (2)-(4). In this paper, we propose a three-step learning method for the code clone elimination problem targeting (2), which consists of (1) understanding how to solve the problem, (2) pointing out the code clones in the problem code, and (3) writing the answer code. Through applications of the proposal to students in our group, the effectiveness is confirmed.
