Abstract

This study investigated the extent to which it is justifiable to consistently employ cut-off scores of 100% in adaptive learning systems (ALSs) and whether it might be more desirable to employ more flexibility in these scores. To answer this question, we collected teachers’ opinions on the topic through a poll, a questionnaire and interviews. In addition, we conducted an experiment in which we tested participants’ knowledge retention a day after they studied facts under two different cut-off scores (high and low), within Memorylab (an ALS). We found the teachers participating in our study generally opposed to scores of 100%. Instead, they prefer lower scores that they assumed would result in a balance between protecting student well-being and a minimum workable knowledge level. In addition, most teachers prefer to differentiate between students and learning tasks when setting cut-off scores. The results of our experiment provide evidence that studying under different cut-off scores within Memorylab can effectively achieve such differentiation: learning based on the high cut-off score was associated with significantly higher levels of long-term knowledge retention one day later compared to the low cut-off score. In addition, we found that learning based on the low cut-off score was associated with higher learning efficiency compared to the high cut-off score. Therefore, learning based on a lower cut- off score could help to reduce time spent on studying and reduce stress among students, thereby further underscoring the benefits of adoption of lower cut-off scores. Overall, the results of this study indicate it would be more desirable to adopt lower and more flexible cut-off scores, as opposed to consistently employing cut-off scores of 100%.
