A DEVICE FOR STUDYING PROBLEM-SOLVING BEHAVIOR.
Robert J. Glaser · 1954
Abstract : A device was developed to study diagnostic problem-solving behavior. It consists of a problem card which describes the problem situation in words, diagrams, or pictures; a procedure board which permits the subject to 'perform' a procedure and obtain feedback cues as a result of having performed the procedure; and a solution board which contains a set of possibly correct solutions which give the subject knowledge of the adequacy or correctness of a particular solution when it is decided upon.
