Effect of instructional procedure and pupil locus of control on achievement and attitudes

The purpose of this study is to determine the effect of instructional procedures differing in degree of student control on achievement and attitudes of pupils identified as having an internal or external locus of control. Two sixth-grade classes (N=47) were divided into internal and external locus of control groups. Half of the internals and externals in each class were randomly assigned a structured instructional procedure and half assigned a contract procedure. A two-week unit on nutrition was taught to all students, using a structured or contract method. There were no significant differences in achievement among any of the groups. However, the internal-contract group seemed to show a more positive attitude toward the unit than did the other three groups. These results suggest that instructional procedure may not differentially affect achievement of internal and external sixth graders over a short period, but that attitudes toward instruction may be affected.
