Computational estimation: Theoretical and methodological foundations

Abstract

The practical significance of computational estimation is noticeable in everyday life, but the place and role of estimation within mathematical abilities is also important. The paper presents the theoretical and methodological foundations of the concept of computational estimation, the development of estimation skills, and it gives a systematic overview of computational estimation strategies. Computational estimation, due to its nature, has not been much examined and a small number of papers that have tested the effectiveness of the teaching instruction have been observed. However, the results so far suggest that it is possible to develop the estimation ability in both children and adults, and that this contributes to mathematical flexibility, better achievement and attitudes towards mathematics. The place of estimation in the curricula was examined and methodical recommendations for teaching were given. Computational estimation should be integrated into as many mathematics teaching content as possible, and new research suggests that estimation skills should be developed from preschool age.
