Welcome to CEAPP

The Corpus of English for Academic and Professional Purposes (CEAPP) is a growing, publicly available, searchable, and longitudinal online corpus of videos and their transcripts of naturally occurring classroom interactions. Housed and curated by the Center for Research on English Language Teaching and Learning at Penn State, the database includes ClassBank, originally part of TalkBank.org, and video data from university-level intensive ESL and STEM classrooms.
