Study skills were an early and important topic in reading; however, since the 1970s, they have received relatively little research attention. The authors systematically analyzed the research conducted on study skills from 1900 to the present. Several themes emerged including: (a) motivation and affect; (b) activities described; (c) metacognition; (d) programs described; (e) assessments created; and (f) the use of study skills in electronic environments. The final theme has made an impact on how students study. The authors make the case that students must learn how to study in a different environment, specifically the electronic environment, to be competitive in today's world. (Contains 1 table.)
