This contribution enters into dialogue with studies conducted both at school and university level on the effectiveness of interaction between subject teachers and language teachers to improve learners' subject-specific discourse literacies.An overview is given of the key findings of a report by the National Center for Literacy Education (2013) in the USA, and main findings are linked to two recent South African studies on collaborative approaches to academic literacy support in higher education. This is followed by a comparison of the school and university settings under scrutiny, with specific emphasis on the shared success factors. An analysis of two curricula for academic literacy offerings at a university that is in the process of introducing subject-specific academic literacy interventions indicates that the effectiveness of the interventions is not necessarily dependent on team teaching approaches, but on institutionally supported, regular, integrative, mutually consultative planning with all stakeholders involved in an atmosphere informed by study and ongoing review. Report (1975) with regard to the implementation of 'language across the curriculum' in South African higher education. One of their primary aims is to "situate strands of current thinking in a framework that could clarify assumptions and implications potentially accepted uncritically today" (Van Dyk & Coetzee-van Rooy, 2012:7). The section of the Bullock report that was found by these authors to be applicable to South African higher education -chapter 26 -focuses on language and literacy policy development and the establishment of support structures for their development. The ultimate aim of the Van Dyk and Coetzee-Van Rooy article is to propose a framework with which insights presented in the Bullock report (1975), and experiences from those who worked towards the implementation of this report in different contexts (Marland, 1977 and Corson, 1975), could be used to guide thinking about the "language and literacy across the curriculum" issue in South African higher education today (Van Dyk & Coetzee-VanRooy, 2012:10).A pivotal issue addressed in Van Dyk and Coetzee-Van Rooy's article (2012:14) is curriculum approaches to support curriculation for the implementation of language across the curriculum. They quote Marland (1977:11) who distinguishes a 'disseminated approach' and a 'specialised approach' to curriculum. Disseminated approaches move the responsibility for the development of academic, quantitative and information literacies to the mainstream, involving language experts as well as faculty, administrators and other stakeholders (compare also Scott, 2009;Jacobs, 2009;Hibbert, 2011). Among the advantages of such models are the 'discursive spaces' they create for collaboration between language lecturers and subject specialists, and the empowerment of subjectspecialists to lexicalise and structure their tacit knowledge of literacy conventions in their specialised discourses.Among the challenges facing this type of model are that subje...
