To meet the challenges emerged from the complex environmental, social, cultural and economic changes in the 21st century, anyone needs critical creative thinking. Although both modes of thinking is different one to another, they are closely related and even complementary. Each person has naturally the potential to think critically and creatively. However, in order to be able to use them, they need to be studied and developed, and it is very effective to do in the classroom either integrally with the school subjects, or through critical and creative thinking explicit teaching. If the mental revolution is to be applied to improve the education sector, one of the most important agenda is to include the programs for developing the creative and critical thinking skills into the curriculum.
