The purpose of this article is to disclose and comment upon some of the conceptual and empirical confusions that confront a revised concept of intelligence which sees intelligence as general skill(s) that can be directly taught rather than as a relatively fixed ability. Implications for teaching thinking skills are discussed. (IAH)

This article responds to a critique of a study in which an ambitious program of thinking skills instruction was designed, implemented, and evaluated. Concepts of intelligence and thinking skills are explored, the relationship between the two is analyzed, and the impact of instruction on both is considered. (IAH)
