RESUMEN
The present study was designed to experiment the effect of De Bono’s CoRT Thinking Program on the Concept Map Performance of Senior Secondary School students of grade IX and X in relation to their level of intelligence. Two identical groups comprised of 51 respondents in each i.e. Experimental and Controlled were drawn with the help of multiclustered random sampling techniques and level testing. While treatment tenure Experimental Groups were taught with CoRT Thinking Program and Controlled Groups were taught with traditional way in a controlled condition as per requirement of experimental method. Results of the experiment were then analyzed by different statistical techniques. It was observed that CoRT Thinking Program has significant effects on concept map performance. Level of intelligence has also been found to have significant effect on some component of concept map performance.
