Contexts as switchmen: The variable effects of formal and informal instructional strategies on student achievement

This study presents an exploratory theoretical framework that analyzes the extent by which the contexts of classroom instruction mediate the effects of instructional strategies on achievement. The study first presents the two main tasks that teachers face in classrooms-teaching, and controlling the social order. The study then elaborates on formal and informal instructional strategies that teachers use to manage these tasks. The main foci of the study is to show that the effects of these different instructional strategies on student achievements vary by grade level. The results suggest that the contexts of instruction determine the magnitude and direction of the effects of instructional strategies on achievement. Positive effects on student achievement appear when a functional congruence occurs between teachers' instructional strategies and the contexts wherein they are used. The analyses suggest that changes in the cognitive, social, and institutional contexts of classrooms may change the relative efficacy of specific instructional strategies. Consequently, researchers should pay more attention to the changes in the sociology of classrooms during students' school careers. This study was supported by a post-doctoral fellowship from the Fulbright Foundation and by a small research grant from The Spencer Foundation. My wholehearted appreciation is given to the support I received from the Foundations. I am especially grateful to Charles Bidwell from the University of Chicago, who encouraged me to pursue this study during my post-doctoral visit in 1994–95. Discussions with Benjamin Wright and his warm support have been more than essential. The hospitality and the academic environment at the NORC and the University of Chicago have done wonders to the fruition of ideas advanced in this study.
