Research Methods Tutor (RMT) is a dialogue-based intelligent tutoring system for use in conjunction with undergraduate psychology research methods courses. RMT includes five topics that correspond to the curriculum of introductory research methods courses: ethics, variables, reliability, validity, and experimental design. We evaluated the effectiveness of the RMT system in the classroom using a nonequivalent control group design. Students in three classes (n = 83) used RMT, and students in two classes (n = 53) did not use RMT. Results indicated that the use of RMT yieldedstrong learning gains of 0.75 standard deviations above classroom instruction alone. Further, the dialogue-based tutoring condition of the system resulted in higher gains than did the textbook-style condition (CAI version) of the system. Future directions for RMT include the addition of new topics and tutoring elements.
研究方法辅导器（RMT）是一个基于对话的智能辅导系统，用于配合本科心理学研究方法课程使用。RMT包括五个与基础研究方法课程的课程设置相对应的主题：伦理学、变量、信度、效度和实验设计。我们使用非等效对照组设计评估了RMT系统在课堂上的有效性。三个班级的学生（n = 83）使用了RMT，两个班级的学生（n = 53）未使用RMT。结果表明，使用RMT所产生的学习收获比仅通过课堂教学高出0.75个标准差。此外，该系统基于对话的辅导条件比其教科书式条件（计算机辅助教学版本）产生了更高的收获。RMT未来的发展方向包括增加新的主题和辅导元素。
