Educational studies of toddlers' number sense and emerging arithmetic skills
The project directs attention to early knowledge of numbers and arithmetic skills and how to support development in preschool education. A pedagogical challenge is to support toddlers’ (1-3-year-olds) competences in a goal-oriented practice, considering that early interventions show large effects in a longitudinal perspective. The DUTTA project contributes knowledge of how children develop from “not knowing” to “knowing” how to use numbers in arithmetical problem solving and develop teaching strategies in preschool. The project is conducted in three preschools during three terms. Data collection and teaching interventions are collectively designed and developed by researchers and preschool teachers. Variation theory of learning is the theoretical framework for interpreting learning and for identifying prosperous teaching strategies.
