First and foremost, Intensive Interaction is highly practical. The only equipment needed is a sensitive person to be the interaction partner. The approach works by progressively developing enjoyable and relaxed interaction sequences between the interaction partner and the person doing the learning. These interaction sequences are repeated frequently and gradually grow in duration, complexity and sophistication. As this happens, the fundamentals of communication are gradually rehearsed and learnt in a free-flowing manner. The style of the teacher person is relaxed, non-directive and responsive. In fact, a central principle is that the teacher person builds the content and the flow of the activity by allowing the learner basically to lead and direct, with the teacher responding to and joining-in with the behaviour of the learner. This simple principle is the one used by adults in interaction with babies during the first year. The first year is the period of development when a baby carries out intense and very rapid learning of the fundamentals of communication. Much of the development of Intensive interaction was based on reading of the scientific research on the way in which human beings learn to communicate during the first year.
It has made a significant contribution to the development of effective communication curriculum for those with complex learning and communication difficulties
The teaching sessions are therefore frequent, quite intense, but also fun-filled, playful and enjoyable. Both participants should be at ease with enjoyment of the activity as the main motivation. A session could be highly dynamic, with a great deal of vocalisation, sometimes with fun-filled physical contacts, or a session may be peaceful, slow and quiet, both these styles will be observes within many classes at our school.
