Thinking about the form of assessment SCT offers for classroom interaction: Dynamic assessment.
Dynamic assessment aims to jointly construct the best performance with the learner. In this sense, DA tells us what students can do "with help" rather than "on their own" as traditional assessment does. DA is future oriented, in the sense that it stretches learners performance and mediates learners 'towards an independent performance...' (Swain et. al, 2010)
This concept was very controversial in my mind at the beginning, because it seemed a little bit unfair and loose. However, it makes a lot of sense to me now, if you think that every time we assess with the traditional methods -for instance, a multiple choice test- we are creating an artificial setting for performance, since it is not very likely to deal with those at work or when communicating with other people in a second language; and opposite to what your parents (and I myself) tell you, you are not alone in life. You interact with people and co-construct meaning in conversation, or aid yourself with books and teachers when creating a code for Astrophysics.
Nevertheless, some issues of accountability emerge and also identity. How do we report results from DA and how we make them valid for other people or institutions? How do we deal with students' expectations of more traditional tests and their (my T_T) obsessive dependance on grades to understand their academic identity?
