How do students feel when the rate of English usage increases from 60% to 90%? This study showed that those students increased the scores of their self-efficacy scale, their reproductions of reading and the item which says “you can keep up with the difficulty of the class.” However, canonical correlation analysis revealed that there were two types, the highly-motivated students and the well-performing students, at a rate of 60 % and 90 %. The characteristics of the two types at the rate of 60 % were found to be different than those at 90%. It proved that the students managed to adapt themselves to their learning environment, where they struggled to understand the meaning of the CE. Those who were weak in English used the patterned procedure as a clue to improve in the classroom. Furthermore, another result proved that the experience of CE in elementary school influenced their mindsets toward classroom English.
