Extensive Reading (ER) has been spreading in many schools and more and more teachers are trying to implement ER into classrooms these days. On the other hand, they frequently face worries and misunderstandings of students, parents, and/or colleagues. School teachers often find it difficult to persuade them because they cannot show them enough evidence. In order to support those ER instructors, this research first reveals that 1) both total word count read and average wpb (words per book) have positive correlation with English proficiency tests and that 2) average wpb has stronger correlation with test results than total word count read. This study may be able to provide ER instructors some tips for guiding ER practitioners properly.
