Research contributes to our world in many different ways, and impact is the benefit research brings to society, outside of academia. In this talk entitled "Research into Second Language Acquisition: Dissemination of Results and Impact," the presenter will first present two research questions and how they set about investigating them. The two research questions are (a) What is the most effective way of teaching business English / workplace English? and (b) How can instruction support the second language development of L2 learners? The presenter will then explain how the research is made accessible to students and suggest what the social impact of their research has been.
