Development and evaluation of a personalized instructional system which enhance the motivation of learners.

传统上，在练习学习中，正确答案的百分比被视为一个反映学习者表现的因变量。从操作心理学的角度来看，我们对强化时间表的了解表明，正确答案是决定学习者学习行为反应率的重要自变量。在这个研究项目中，我们开发了一个个性化的英语拼写学习教学系统，可以控制每个学习者的正确回答百分比，并进行了一些实验来评估我们的系统的有效性。研究对象为10名初中生和大学生。一组参与者在高正确率条件下（约70%）学习英语单词拼写，另一组在低正确率条件下（约20%）学习英语单词拼写。如果将强化计划的知识应用到拼写学习中，我们期望参与者在高正确条件下学习到更多的东西。结果表明，在高正确率条件下，所有学习者都表现出更优异的学习成绩。他们在同样的日常会话中学习了更多的单词，他们在更短的学习时间内达到了学习标准。这一发现可以应用于许多领域。实地演练学习和方法可以激发学生的学习动机。

Traditionally, the percentage of correct answers in drill learning has been treated as a dependent variable which shows the performance of leaner. From the stand point of view of the operant psychology, our knowledge on the reinforcement schedules show that the correct answers are is an important independent variable which decide the response rate of learners studying behavior. In this research project, we developed a personalized system of instruction for English spell learning which can control the each learner's percentage of correct responses, and run some experiments to evaluate the effectiveness of our system. Participants were 10 junior-high school students and university students. One group of participant learned English word spelling in high correct rate condition (about 70%), and other group learned in low correct rate condition (about 20%). We expected that the participants learn more under the high correct condition if the knowledge of reinforcement schedule could be applied in spell-learning. Results showed that all learners showed more excellent learning performance in the high correct rate condition. They learned more words in the same daily session, they reached criteria of learn in shorter learning time. This findings can be applied to many. field of drill learning and the method may encourage students' motivation to study.
