A study of the history and systems of the psychology of learning is su
bstantive and complex, but the controversy over what is learning and w
hat are the products of the learning process should be studied by teac
hers. The emphasis of learning on the stimulus side by Pavlov to the f
ocus of reward and reinforcement on the response side by Thorndike and
Skinner should be evaluated. The bridge from S-R to S-O-R learning by
Mowrer's emotional conditioning, and the interpretation of internal a
nd cognitive factors of social learning (Bandura) and information syst
ems theory should be examined. From social learning and information sy
stems has emerged a psychology of pedagogy.
