# The Use of Worked Examples as a Substitute for Problem Solving in Learning Algebra

@article{Sweller1985TheUO, title={The Use of Worked Examples as a Substitute for Problem Solving in Learning Algebra}, author={John Sweller and Graham Cooper}, journal={Cognition and Instruction}, year={1985}, volume={2}, pages={59-89} }

The knowledge required to solve algebra manipulation problems and procedures designed to hasten knowledge acquisition were studied in a series of five experiments. It was hypothesized that, as occurs in other domains, algebra problem-solving skill requires a large number of schemas and that schema acquisition is retarded by conventional problem-solving search techniques. Experiment 1, using Year 9, Year 11, and university mathematics students, found that the more experienced students had a…

The acquisition of problem-solving skills in mathematics: How animations can aid understanding of structural problem features and solution procedures

- Mathematics
- 2010

It is argued that so called hybrid animations would be most effective for acquiring knowledge prerequisites for solving mathematical word problems, because they show the continuous transition from a concrete, but superficial problem representation to a more abstract, mathematical problem model that forms a basis for solving a problem.
