Rating scales and rubrics are commonly used measurement tools in educational contexts.
Unfortunately, there is a great deal of controversy surrounding how data derived from these …

The number line estimation task is widely used to investigate mathematical learning and
development. The present meta‐analysis statistically synthesized the extensive evidence on …

Mental representations of numerical magnitude are commonly thought to undergo
discontinuous change over development in the form of a “representational shift.” This idea …

We tested children in Grades 1 to 5, as well as college students, on a number line estimation
task and examined latencies and errors to explore the cognitive processes involved in …

In this study, we aimed at investigating whether it is indeed the spatial magnitude
representation that links number line estimation performance to other basic numerical and …

Research has shown that difficulty adaptation is a promising instructional technique in digital
game-based learning. Nevertheless, although the strength and direction of difficulty …

Although the development of number-line estimation ability is well documented, little is
known of the processes underlying successful estimators' mappings of numerical …

Learning of the mathematical number line has been hypothesized to be dependent on an
inherent sense of approximate quantity. Children's number line placements are predicted to …

Despite their importance in public discourse, numbers in the range of 1 million to 1 trillion
are notoriously difficult to understand. We examine magnitude estimation by adult A …

A large body of evidence supports the central influence of counting in the development of
adequate arithmetic skills. Moreover a substantial amount of children with mathematical …
