The first volume details the procedures used in second, fourth, and sixth grades and inservice training projects and their results; the second presents data on achievement, attitude, and interaction analysis. The purpose of the project was to test some theoretical principles of teacher influence with particular emphasis on different patterns which occur in different teaching situations. The four main objectives were 1) to collect normative data; 2) to analyze verbal interaction patterns, at three grade levels, in classrooms that score above and below average in pupil achievement and positive pupil attitudes; 3) to develop procedures and equipment to tabulate coded interaction data directly into a matrix; and 4) to work with a small group of teachers to help them modify their teaching behavior and to identify models of classroom interaction. The results are discussed in detail under four headings: 1) teaching effectiveness as a field of knowledge; 2) helping a teacher change his teaching behavior; 3) outlining the contributions which the project makes for those who conduct research; and 4) describing some of the contributions of this project for the classroom teacher. Appendixes to volume 1 include the achievement and attitude tests used for each grade, the inservice training instruments, and the analysis of covariance for the sixth grade. (MBM)
