"Probably the best evaluation of a thinking skills programme
I have seen . . .a model of what an evaluation can be. . . a real-world
one, with all the problems of real-world schools. . .the evaluation
is amazingly comprehensive, looking at both pupil and teacher performance,
and using a variety of different kinds of methodologies, including
paper-and-pencil tests, observations, checklists, questionnaires,
and the like. This is really a class piece of work."
