Inverse is a critical topic throughout the K–16 mathematics curriculum where students
encounter the notion of mathematical inverse across many contexts. The literature base on …

The main goal of the present research is to gain a better understanding of the consequences
of background noise on learning, with a specific focus on how noise may impair maths …

We investigated elementary school children's use of direct subtraction (DS) and subtraction
by addition (SBA) when mentally solving multi-digit subtractions. Fourth-to sixth-grade …

Interleaved practice is a promising approach to foster the adaptive use of subtraction
strategies. By intermixing strategies, comparison processes are evoked, which prompt more …

We propose to assess conceptual knowledge of mathematical notions by having recourse to
isomorphic word problems. We assumed that failing to solve isomorphic problems is an …

Informal strategies reflecting the representation of a situation described in an arithmetic word
problem mediate students' solving processes. When the informal strategies are inefficient …

This chapter provides an overview of the current findings about (the obstacles in) primary
school children's strategy use in the domain of multi-digit arithmetic. This involves addition …

Interleaved practice combined with comparison prompts can better foster students' adaptive
use of subtraction strategies compared to blocked practice. It has not been previously …

Using the choice/no-choice methodology we investigated Dutch fourth graders'(N= 124)
adaptive use of the indirect addition strategy to solve subtraction problems. Children solved …

To date, of the many studies on early algebraic thinking, none, to our knowledge, has
examined the relationships between algebraic thinking and negative numbers. Students …
