In this paper the augmentation of worked examples with animations for teaching problem-solving skills in mathematics is advocated as an effective instructional method. First, in a cognitive task analysis different knowledge prerequisites are identified for solving mathematical word problems. Second, it is argued that so called hybrid animations…

A question-answering strategy for problem solving is described, and the effects of instruction in that strategy on student learning are examined in a computer-assisted context involving 46 fifth graders. The reasons students trained in guided questions performed better are discussed. (SLD)
