English language is the primary medium of learning and teaching at the Open University and is therefore central to students’ attainment and progression (see Erling, 2009). Over the past five years, six models of English language across the curriculum and three models of English language student support have been established at the OU. In 2011, the English Language Provision (ELP) Programme carried out an evaluation of the impact of these models on students, and to a lesser extent tutors and module teams (see Adinolfi and Kerr, 2011). As a result of the evaluation, the ELP Steering Group has proposed that a mixed economy of language provision be considered consisting of English for academic purposes modules and a range of language awareness and development provision ‘embedded’ within subject and programme areas. This presentation will outline the models and the findings of the evaluation and draw out the implications for the university’s curriculum development and widening participation strategies, including a number of key focus areas from OU Futures 2010-13.
