Elevers problemlösningsstrategier
En studie av gymnasieelevers val av strategier vid problemlösning
The purpose of this study is to examine senior high school students? strategies and reasoning when solving mathematical problems and make a review of the concept problem solving. The purpose is also to examine if the students? choice of strategies are influenced when their mathematical knowledge is improved.The study was conducted in two science classes at a senior high school. All the students were asked to individually solve two mathematical problems. After that, a few randomly chosen students were interviewed and asked to elucidate their process of thought when solving the problems. The study revealed that the students had preferred to use graphic strategy, algebraic strategy and reverse counting strategy. A small number of other strategies are also represented.Moreover, the result showed that students with a higher mathematical level of knowledge tended to choose algebraic strategy.
