Investigated the influence of locus of control and diagnostic testing with prescribed remediation on immediate and retained science achievement of preservice elementary education majors (N=43) during three introductory biology units. Findings, among others, show no locus of control times treatment interactions and differences in achievement…

Reports on effects of Individualized Goal Setting (IGS) Audio Tutorial (AT) instruction compared to classic AT instruction and effects of pretesting compared to no pretesting on students' locus of control. Indicates no significant effect on students' locus of control between IGS-AT v AT or between pretesting v no pretesting. (DS)

Investigated effects on meaningful learning achievement of concept-related instructional organization and locus of control orientation of 541 high school students. Indicates that externally-oriented subjects exposed to the treatment generally retained more than those in a comparison group. Other results are reported and discussed. (Author/JN)

Cites results of a study that assessed the effects of diagnostic prescriptive teaching strategies and locus of control on various cognitive levels of science achievement of college biology students, also examined the interaction between the instructional strategy and students' locus of control. Students' attitudes were also examined. (CS)

Measured the effects of three variations in the use of diagnostic-prescriptive (DP) teaching on the cognitive and affective biology achievement of high school students (N=93). Variations included: (1) no DP assistance; (2) teacher-managed DP; and (3) student-managed DP. Results favor DP approaches. (Author/JN)
