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.
