It became almost a cliché to say that in the twenty-first century education cannot be based on teaching specific content and skills but should focus on “learning how to learn” and on the development of more general cognitive abilities. There are two major proposals for handling this problem. The first suggests focusing on students’ general cognitive and problem-solving skills which can then be applied in any content area. The second proposal is to develop cognitive strategies “inside” the curricular areas. The first approach thus calls for an addition of a new learning subject – “cognitive lessons” – while the second presupposes a rather radical reform of curricular teaching/learning that would assign cognitive goals to subject lessons. “Instrumental Enrichment” is analyzed as an example of a standalone cognitive program that develops such general skills as analytic perception, comparison, and classification that can then be “bridged” to curricular material. The cognitive infusion approaches propose to infuse cognitive skills into the curricular lessons without significant changes in the curricular material itself. Finally, the developmental education approach presupposes a rather radical change in the curricular material that would allow every curricular lesson to be turned into a cognitive lesson.
