In Improvisation Theatre, actors create a performance on the spot; there are no lines to memorise or rehearse. Improv actors use a series of activities which help them to develop their techniques in listening and connecting with other actors. They can then respond better to new contexts and create original and spontaneous plays. “(…) improvisation is characteristic of any human action that is not fully scripted and determined – which is the case in most of our daily encounters”. (Sawyer, 2011, P. 12) This strongly resonates with the ideal context we want to provide for language learning: a supportive and safe environment where students learn to be creative, spontaneous and willing to take risks. The role of the teacher is to offer this context where structure and improvisation are in balance. At the LSE Language Centre we have been using Improvisation activities in English for International students since 2012 and we are currently piloting it in other languages. In addition, in sessions with teachers, we explore Improv activities and applications, with the aim of inspiring teachers to incorporate these techniques into the classroom, which we think transform the student learning experience. In this interactive workshop we will briefly present our findings, based on student feedback and teacher observation and practice a series of activities with attendees so that they experience Improv first hand.
