| Abstract | #englisch#The number line estimation task captures central aspects of children´s developing number sense, that is, their intuitions for numbers and their interrelations. Previous research used children´s answer patterns and verbal reports as evidence of how they solve this task. In the present study we investigated to what extent eye movements recorded during task solution reflect children´s use of the number line. By means of a cross-sectional design with 66 children from Grades 1, 2 and 3, we show that eye-tracking data (a) reflect grade-related increase in estimation competence, (b) are correlated with the accuracy of manual answers, (c) relate, in Grade 2, to children´s addition competence, (d) are systematically distributed over the number line, and EUR replicate previous findings concerning children´s use of counting strategies and orientation-point strategies. These findings demonstrate the validity and utility of eye-tracking data for investigating children´s developing number sense and estimation competence. (DIPF/Orig.). |
