Tone Kvernbekk: Evidence Into Practice: Why We Need An Argumentation Model
Prof. Tone Kvernbekk is visiting the Science Colloquium Series. Kvernbekk is Deputy Head and Head of Studies at UiO's Department of Education. Her professional interests are primarily within philosophy of science, philosophy of education, argumentation and narrative theory, or some combination of them, as exemplified in this talk.
It is demanded of both professions and professional education programs that they be research-based. In this talk my point of departure is as follows: Evidence, for example in the form of data from randomized controlled trials (RCTs) cannot in themselves tell us what we should do in practice. To make use of evidence in practice we need to fit it into practical reasoning, and for that we need an argumentation model. Different models yield different roles for the evidence and suggest different contributions evidence can make to practice. I shall discuss three models: Philip Davies (a classic in evidence-based practice in education), Nancy Cartwright (a model based on an explicit view of causation) and Stephen Toulmin (an argumentation-theoretical model). I shall discuss what role evidence is accorded in each model and what kind of questions the models can and cannot answer.
