Benson, Jean S.; Yeany, Russell H. – Journal of Research in Science Teaching, 1986
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…

Yeany, Russell H.; Miller, P. Ann – 1980
Experimental studies based on diagnostic prescriptive instruction, as it affects science achievement of college, high school, and middle school students, were analyzed statistically by the procedure of meta-analysis to determine the effectiveness of this instructional treatment. "Effect size" was calculated on each of 30 dependent…

Yeany, Russell H.; Miller, P. Ann – Journal of Research in Science Teaching, 1983
Reviews and analyzes results of experimental studies based on diagnostic prescriptive instruction as it affects science achievement. Results indicate such instruction significantly and positively influences science achievement, but that there is no clear indication that use of prescription/remediation in addition to diagnosis brings about…

Benson, Jean S.; Yeany, Russell H. – 1980
Reported is a study that explores the effect on student achievement of diagnostic-prescriptive instructional strategies on preservice elementary education majors (N=43) enrolled in an introductory biology course. Factors of pre-treatment achievement and locus of control were analyzed as well. Units on Mendelian genetics, modern genetics, and…

Saunders, Ramona L.; Yeany, Russell H. – 1979
Reported is a study designed to determine the effects of diagnostic testing followed by prescribed remediation on the immediate and retained science achievement of middle school students, and to determine if effects of treatment were consistent across students' race and locus of control (LOC) levels. Three intact seventh-grade science classes were…

Saunders-Harris, Ramona; Yeany, Russell H. – Journal of Experimental Education, 1981
Subjects were assessed for locus of control and experienced either: no diagnosis; diagnosis; or, diagnosis and remediation. Immediate achievement was measured twice during the experiment; retention was measured 30 days later. Findings suggest that diagnostic or diagnostic/remedial instruction is effective in increasing middle school science…
