Extensive reading (ER) is regarded as an effective method by which English language learners can make substantial gains in reading fluency and overall language acquisition. For language teachers, however, actual implementation of ER into curricula has proved daunting. In response to three ER management issues: establishing accountability, providing appropriate assistance, and ensuring students are reading large quantities of text, the authors will report on the implementation of two online ER management systems designed to overcome these hurdles - Xreading® and M-Reader. These online reading support systems were utilized by two senior high-school classes studying in a university bridging program. One class (n=24) read paperback graded readers (GR) but completed online quizzes provided by M-Reader®; the second class (n=20), using the Xreading® platform entirely, read e-books on their smartphones or personal computers and completed online post-reading quizzes.
