This study used the learners' eye movement data to observe the learner attention impact of digital material with immediate feedback and delay feedback, and observe the different eye movement data when using different reward case. In this study, our object is eight 12-year-olds young people. The experimental independent variables have ”feedback”, ”sex” and ”learning achievement”. The experimental dependent variable is the learning attention of young people. According the experimental results, the discussion is as follows: (1) this study prove immediate feedback can enhance the learning attention. (2) In immediate feedback, boys have higher learning attention than girls. Learning attention doesn't have change in learning achievement factor. (3) After the feedback happened 1 sec., learning attention becomes higher in immediate feedback. Finally, the future work of this study can add the experiment population and use brain wave measurement to observe the learning attention of young people.
