Eight propositions regarding the interaction of teachers and students to create educational outcomes are presented and discussed: 1. It is necessary to look at both cognitive and affective outcomes whenever we want to evaluate the effectiveness of teachers, or an educational program. 2. There is a need for more research on the reciprocal interactions that constitute the learning process, e.g., the ways in which student behavior and teacher behavior affect each other. 3. There are important differences in the dynamics of the learning process among students from different cultures and no single teaching style works equally well with all of them. 4. Differential educational strategies must be designed that will somewhat equalize the educational outcomes between middle class children and the lower socioeconomic level children. 5. The emotional adjustment of students often has a powerful facilitating or deterrent effect on their mastery of cognitive skills. 6. To study each of these problems requires a research design that looks at the interacting effects of teacher and student characteristics on multiple educational outcomes. 7. The most effective learning systems deal with each student's individual learning needs. 8. The major task of the future is the implementation of these educational strategies. (JMF)
