Team Work
The class teacher/s and student/s need to work like a team, with the teacher being the coach who needs to continually encourage, motivate and intrigue each and every player, demanding high performance while ensuring that no individual gets bogged down in detail or overwhelmed with targets. This is particularly difficult in the sessions immediately after mimicking has been introduced since students become easily confused and tired when they first tackle mimicking. It is essential that each and every student understand why he or she is doing each activity, without taking undue amounts of time to explain. Whether the target is speed, creativity, effective use of repetition, making short clear sentences or so on, it is essential that every student is aware that the particular target is a guideline, and may be modified by them to suit their needs.
The need for speed is not a transparent goal and causes many cognitive problems for students since few realize the link between the ability to talk fast and easily understandable pronunciation and meaning, nor do most quickly realize that they are actively learning vocabulary items or good syntax through the peer-on-peer activities, Indeed it will be quite some time before these processes become self-evident and even more so in seminar classes. It's relatively easy to get most students intellectually and physically engaged in actively learning with verbally active classes while the real trick is to get everyone interested. If it's boring for the teacher it will probably be even more so for the students, especially for those who want cognitive understanding before they tackle something. These students are not recalcitrant, they reasonably expect to understand what they're doing and clearly identify their targets before they do anything. It is up to the "coach" to make sure that participants see the relevance of what they're doing and are actively interested in achieving either their own personal goals, the activity targets, or both through doing the activity in an active way.
