Observation Is Insufficient for Discovering that the Surface of Still Water Is Invariantly Horizontal.
Among women college students who did not know that the surface of still water in a bottle is always horizontal, two types of specific task procedures designed to elicit self-discovery of the principle were ineffective. Failure to acquire the concept was reflected in inaccurate responses on the adjustment task and by inability of students to verbalize a correct strategy.
