ABSTRACT
This chapter focuses on an extensive study of the effects of Edward de Bono’s cognitive research trust (CoRT)-1 material on 67 Grade-7 students. With reference to measuring the effects of a thinking skills program, de Bono has discussed the difficulty of the problem: “Hard data are judged to be irrelevant or the result of teaching the test. Soft data in the form of teachers’ comments are judged to be biased or subjective. The memory of CoRT was assessed on ability to recall and describe each of the 10 areas covered in CoRT-1. A composite percentage score was derived for each student. De Bono claims that IQ test scores should not be affected by CoRT training. The Self-Concept as a Learner Scale was chosen as the most relevant scale available for measuring de Bono’s concept of self-concept as a thinker, from a perusal of Buros and the literature on measuring aspects of self-concept.
