Linear Measurement in the Early Grades
Werner Liedtke
Perhaps the greatest quantity of work in the field of intellectual development and concept formation has been conducted by the Swiss psychologist, Jean Piaget. He has concerned himself not only with the learner, but also with the substance to be learned and its structure or logical organization. Piaget set himself the task of investigating empirically the basis for man’s conception of the real external world. With his ingenuous methods and experiments he has probed into the growth of children’s concepts in a variety of areas.
