This presentation will introduce and demonstrate the Online Graded Text Editor (OGTE), a free, web-based tool developed by Dr. Charles Browne and Dr. Rob Waring to assist teachers doing extensive reading with turning ungraded webpages and content into student-friendly texts at just the right level. OGTE takes inspiration from previous well known tools made for researchers such as VocabProfile by Tom Cobb and AntWord Profiler by Laurence Anthony, but with an eye towards making the tool more user-friendly for practicing teachers and content developers. OGTE allows users to analyze and write texts utilizing a wide range of popular corpus-based vocabulary lists including the many lists from the NGSL Project, CEFR wordlists, Cambridge wordlists, the Oxford 3000 and the 20 levels used both at ER-Central.com, the free extensive reading site developed by Dr. Browne and Dr. Waring as well as the Extensive Reader Foundation Graded Reader Level Scale.
