The purpose of this study was to gain insight into overcoming the high dropout rate issue in computer-based learning. For this purpose, we focused on goal setting that acts as a source of motivation. We investigated how learners can be motivated by encouraging them to set effective goals by themselves. We used average scores as reference information and examined its effects on goal setting and task motivation. Three experiments were conducted using a sequential addition task in which participant’s task motivation was reflected in their performance. The presented average scores in comparison with participants’ own scores on the task were manipulated (high / low / no presentation of average score), and we compared goal set points and task motivation between each group. The results showed that participants in high average score condition set higher goals than participants in other groups, and there were positive correlations between goal set points and task motivation. Based on the results, we discussed the effectiveness of presenting reference information to encourage learners to set effective goals for sustainable computer-based learning.
