Cecilia d'Oliveira and colleagues recently wrote an essay in Science about MIT's OpenCourseWare initiative, ten years after its inception. Among the stats:
OCW currently receives upwards of 1.5 million visits each monthfrom 900,000 unique individuals. Students have grown to42% of the audience, and educators and independent learnersnow constitute 9% and 43% of visitors, respectively. Twelvepercent of educators responding to a March 2010 visitor surveyindicated that they do incorporate OCW materials into theirown content as anticipated, but educators more frequently useOCW for personal learning (37%), to adopt new teaching methods(18%), and as a reference for their students (16%). Studentswere largely expected to use the site as a supplement to materialsthey received in their own classes, a use identified by 40%of students. Just over 43%, however, indicated that they alsouse OCW for personal learning beyond the scope of their formalstudies, and a further 12% use it as an aid in planning theircourse of study. Independent learners use OCW in a variety ofpersonal (41%) and professional (50%) contexts, including home-schoolingchildren and keeping up on developments in their professionalfield. 66% of visitors indicate they are mostlyor completely successful at meeting their educational goalsfor visiting the site.
