This study statistically examines students who conduct extensive reading in the first and second semesters by focusing on the reading volume of word counts to address the following research questions: 1) Is there a difference in word counts between students who conduct extensive reading in the first semester and those who continue it in the second semester? 2) Are there any differences in word counts between the three groups: students who conduct extensive reading for the first time only in the first semester, those who conduct it for the first time only in the second semester, and those who conduct it in both semesters? In 2017, extensive reading was implemented for 31 second-grade nursing students. No significant differences were detected for the first question. However, approximately 73% of students increased their word counts. Regarding the second question, a significant difference was found between the two groups such that certain students decreased their word count, which practitioners should be aware of. If a class includes experienced students who read extensively, they can serve as role models for novice students practicing it for the first time.
