Abstract
In recent years, some reports have begun to show a significant relationship between the scores of English proficiency tests and the amount of time spent studying in e-learning（microstep study）developed by us. To date, no reports about e-learning exhibit a significant relationship with comprehensive English proficiency test performances. These results are due to a learning method based on the characteristics of implicit memory, which is the basis of language proficiency, and a new data collection technology（scheduling）that collects a large amount of longitudinal data with matching time conditions to achieve effective English vocabulary acquisition. This paper introduces the features of implicit memory, which is the foundation of linguistic ability, and a scheduling technology that takes these features into consideration to collect high-quality longitudinal data. Furthermore, by introducing a new test principle, we achieved the automation of formative evaluation, which supports knowledge acquisition. Finally, based on the background to the development of the ʻmicrostep study’, we consider what each researcher should do to advance DX in education.
