Revelations from Three Consecutive Studies on Extensive Reading

■ This paper presents three consecutive studies on the effect of extensive reading on the development of reading and vocabulary for Taiwanese university nonEnglish majors. Each study used a different approach, with subsequent studies adjusting the methodology in response to the results of the previous year. These results confirm other findings, using different subjects in other countries, that (1) extensive reading can be integrated into an EFL curriculum, termed in-class sustained silent reading, at the university level; (2) extensive reading is at least as effective and efficient as traditional instruction in acquiring English as a foreign language and is more effective than traditional instruction when the treatment duration is longer; (3) book access and self-selection of reading are two keys to the success of a sustained silent reading program.
