Professor David Crystal's world-leading research on language policy, diversity and usage, conducted at Bangor since 2000, has led to a transformation in terms of public and political attitudes, both nationally and internationally, towards the nature and use of language in public and private discourse. In particular, the research has led, since 2008, to an increased awareness of linguistic diversity, changes to governmental policies on language, and the development of the world's first targeted online advertising technology, which today indexes billions of impressions across 11 languages to provide real-time data services in the emerging online advertising world.
This research by Professor Yaron Matras has impacted on the way local services communicate with minority populations by encouraging them to re-assess language needs. It has had its effects in the fields of health and welfare, education, and policy making in relation public services. In particular it has demonstrated the need to base language policy on reliable mechanisms of data collection and the assessment of such data. One of the key outcomes was the establishment of the world's largest online language archive, Multilingual Manchester. The research also highlighted the existence of relatively unknown languages such as Kurdish and Romani in Manchester. It has also helped explain communication patterns among people who speak related dialects, such as immigrants from different Arabic-speaking countries, and has shed new light on the way in which people who are multilingual make use of their languages.
The research of Professor Paul Simpson and Dr Joan Rahilly has informed and enhanced the broader awareness and understanding of English language in the context of secondary level education in Northern Ireland, and has had particular influence on both clinical and developmental assessment of language use. The end users who have benefited from this research include (i) schools, colleges and lifelong learning, (ii) health and well-being agencies, and (iii) voluntary organisations and charities. The main achievements can be summarised as:
Dr Julia Sallabank's research into Guernsey's little-studied indigenous language, Guernesiais, has greatly informed language planning and policy on the island, particularly with regard to teaching methods and raising awareness of the language among the population. Moreover, her documentation of Guernesiais, specifically the recording of audio samples, constitutes a significant contribution to the preservation of Guernsey's identity and cultural heritage. Sallabank's broader expertise on the revitalisation of endangered languages has also been solicited by language officials elsewhere, notably Jersey, the Isle of Man and New Caledonia, and resulted in her participation in UNESCO's Panel of Experts on language diversity.
By 2008, Welsh language policy was failing to deliver consistent bilingual public services in Wales. Research at Cardiff University's School of Welsh helped UK and Welsh Government policy-makers understand the weaknesses and inconsistencies of the language regime. The research also made policy-makers aware of alternative regimes and legislation in state-wide and devolved governments overseas. Outcomes based on Cardiff recommendations include:
The Natural Language Toolkit (NLTK) is a widely-adopted Python library for natural language processing. NLTK is run as an open source project. Three project leaders, Steven Bird (Melbourne University), Edward Loper (BBN, Boston) and Ewan Klein (University of Edinburgh) provide the strategic direction of the NLTK project.
NLTK has been widely used in academia, commercial / non-profit organisations and public bodies, including Stanford University and the Educational Testing Service (ETS), which administers widely-recognised tests across more than 180 countries. NLTK has played an important role in making core natural language processing techniques easy to grasp, easy to integrate with other software tools, and easy to deploy.
The EPP Project identifies criterial features for second language acquisition. It has engaged stakeholders in the teaching and testing of language learners. This is facilitated by the EPP network and website. The project has enabled Cambridge Assessment to define the English language constructs underlying Cambridge examinations at different proficiency levels more explicitly. The work has improved the tests themselves, but also allowed Cambridge Assessment to better communicate the qualities of their tests for accreditation and recognition. Stakeholders are more actively engaged through provision of resources for teachers, testers, ministries of education etc., on the website, and in seminars. The project has led to further research with an international language school, which has led to teachers and parents of the school pupils being more aware of the needs for successful second language acquisition.
Research by Macaro and collaborators since 1999 led to the distillation of eight principles regarding foreign language pedagogy, and to the development of video- and paper-based materials to support the application of these principles in teacher pedagogy and in teacher education programmes in England. The application in Schools and Higher Education Institutions was facilitated through an ESRC-funded impact project involving language teachers and teacher educators, and it was extended and sustained through the creation of practitioner clusters based on the research. Teachers report that changes have taken place in their modern languages departments following engagement with the research, with benefit to student learning; these changes have included much greater, and better quality, interaction in the foreign language, and a greater focus on processes and strategies in skills development. Teacher education programme providers have incorporated the research-based principles into their programmes, with impact on their student-teachers' practice.
The research findings have led directly to a decision by Cambridge English Language Assessment to change the assessment criteria in their examinations to include assessment of metaphor use. The availability of the research report on the Cambridge website widens the impact of the findings to English Language Teaching and Assessment more broadly, changing attitudes to the assessment of metaphor use at the crucial university-entry level in particular.
The findings have also led to change in the advice given by the British Council for those involved in communication with people from different linguistic backgrounds. The advice is available on their website, which receives several million hits per year (see below for details and exact numbers of hits). This advice has been amended to include information on metaphor. The website has been used by teachers to improve language teaching materials and enhance the way that students are helped to engage in academic courses in English.
Cambridge English Language Assessment is a sector leader and delivers assessment to just under 4 million students per year, including the 1.5 million candidates who take the International English Language Testing System (IELTS) for entry to English-speaking universities. Cambridge examinations are recognised by 13,000 institutions in 130 countries. The British Council is a global leader in English Language teaching and is a respected provider of impartial advice. The adoption by these agencies of these research findings can be expected in turn to lead to a greater focus on metaphor in language classrooms around the world.
This impact is on educational policy and practice in relation to the international teaching of German as a foreign language and is based on research into differences in linguistic variation between England and Germany. The differences lie in: perception of non-standard varieties in the two countries; the status of the standard language in each; and different attitudes towards it. The research stimulated debate, in Germany and abroad, about the variety of German appropriate for use in classroom instruction, and resulted in acceptance that teaching only the register of formal writing is not adequate to the needs of contemporary communication. New teaching manuals have been produced and curricula revised, placing greater emphasis on everyday speech.
