A Test of a Model of Educational Productivity among Senior High School Students

AbstractData from a national sample of 1,955 17-year-olds participating in the National Assessment in Science in 1981-82 were used to test a model of educational productivity involving ability, motivation, quantity and quality of instruction, and the environments of the home and class. When a set of 11 individual predictors were regressed on achievement and attitude, the educational productivity model was generally supported. With predictor variables controlled for one another, student achievement was related to ability, motivation, science, amount of homework, class environment, home environment, amount of television viewing, sex, and race. Student attitudes were found to be positively related to ability, motivation, attitude toward the teacher, amount of homework, the class environment, and the home environment.
