Teachers......

Teachers are so busy that they just don't have much time for lesson design and development. They need to throw together a lesson in a few minutes on a Tuesday night that they can use with their students the next day. They need an approach that takes very little time but delivers good results.
Each day the teacher considers lesson objectives and strategies before students walk through the door. Once the students appear and the lesson begins, it is usually necessary to shift the lesson plan as the class proceeds and the teacher notes the reactions of various students. In many cases, the teacher must dig deep into the skill repertoire to find tactics that seem right for the situation that has developed. In some cases, the first new strategies will be successful, but it is a trial-and-error process.
Good teachers effectively "stumble toward competence" as they try out an array of strategies and tactics until they find the right ones. Experience helps to inform their choice of strategies, but novelty stands in the way of any teacher being able to coast along banking on previous experience.
Effective teachers engage in daily match-making, creating conditions to promote learning and connecting tasks with students, giving them what they need to be successful while nurturing the process and minimizing obstacles. The best teachers customize lessons so that each student is afforded opportunities that match needs, interests, preferences and skill levels.
