Abstract: This is an experimental study on the effect of thinking lesson on stu-dents' thinking ability. The results show that thinking lessons can signifi-cantly raise the speed of thinking, broaden the scope of thinking,strengthen the ability to elaborate and improve creative thinking. Increase in the ability to generalize is not significant. We found that the potential of cultivating students' thinking abilityexists in school teaching, and the breakthrough point to tap the potentialis to teach correct thinking procedures and make them a habit. Becausethe general procedure and the one related to specific subjects are bothimportant, we suggest that the two kinds of thinking lessons be integra-ted.
