  14. 15. Educational ideal: basic argument Any system of education should aim to teach the knowledge, develop the skills, and foster the attitudes and dispositions of a “critical thinker”. A disposition to respond to perplexities with skillful critical thinking is helpful to anyone in managing their life. Attention to the knowledge, skills and attitudes of a critical thinker can improve them noticeably. Everybody encounters perplexities about what to believe or what to do. Skillful critical thinking is more likely to lead to a satisfactory resolution of such perplexities. Noticeable gain, more than expected. (Hitchcock 2004) Other studies found greater gains. A student can improve thinking in six different respects. (Swartz & Perkins 1990)
