Correlational findings from four major teacher effectiveness studies were incorporated into a teacher training program whose preliminary results are presented in this set of five papers. N.L. Gage begins by briefly introducing this program's background and rationale. The second paper, Experimental Effects of In-Service Teacher Training Derived from Process-Product Correlations in the Primary Grades, by John Crawford and Jane Stallings, examines teaching skills which are associated with student achievement; instructions for developing teachers' skills are appended. Lyn Corno, in Effects of Parent Instruction on Teacher Structuring and Student Participation in the Third Grade: An Aptitude-Treatment Interaction Approach, discusses the effectiveness of a parent assisted program to develop students' cognitive and behavioral processes which promote successful adjustment to school. Although student attrition and aptitude treatment interaction complicate the analysis of program effects, results are generally positive. In the fourth paper, Nicholas Stayrook and John Crawford present preliminary findings from the analysis of classroom observational data. Finally, Alexis L. Mitman discusses Teacher Self-Report in an Experiment on Teacher Education and Effectiveness. Teachers' reactions to their training and factors affecting teacher training implementation are valuable in interpreting other findings. (Author/GDC)
