Problem solving, not placing blame, is important. It shifts from a person problem to a process problem which is completely non-judgmental. The QTL members bring suggestions which are discussed and voted on by the entire QTL team. If passed, it is brought before the class and voted. If passed, it is implemented immediately.
Students feel that the faculty has listened and are more responsive to listen to the faculty.
Another part of Kizen is continuous assessment, not summative on the part of assessing the student's performance, but formative on the part of assessing the student AND the faculty performance. Continuous assessment and continuous improvement, a little at a time. The advent of the computer in the classroom is lending itself to facilitate this process. I have all of my assessments on-line. The last assessment provided by the student is what is taken as the evaluation.
