The National Council of Teachers of Mathematics (NCTM) emphasizes the teaching of "Big Ideas" in mathematics. This study focuses on the part-part-whole (PPW) relationship as a crucial aspect of word problem solving involving addition and subtraction. This study, conducted in the United States, evaluated the effects of conceptual…

This study examines relationships between mathematical problem-solving performance (in terms of strategies used and accuracy) and the main cognitive domains associated with mathematical learning (i.e. executive functions, verbal comprehension and social perception) of children with and without autism spectrum disorder (ASD and non-ASD resp.). The…

The purpose of this study was to examine the effects of a number line intervention with supported self-explanation on student understanding of fraction magnitude and quality of explanation. Participants were three U.S. middle school students with significant behavior problems. Participants were given eight lessons containing explicit instruction…

Intervening on causal systems can illuminate their underlying structures. Past work has shown that, relative to adults, young children often make intervention decisions that appear to confirm a single hypothesis rather than those that optimally discriminate alternative hypotheses. Here, we investigated how the ability to make informative causal…

The purpose of this investigation was to examine communication skill use and related characteristics, as well as factors associated with problematic communication during conferences, in parents and teachers of children on the autism spectrum (AS). Participants were 36 parent-teacher dyads who completed questionnaires on communication, defined…

During the past 20 years, numerous studies examining the use of problem posing in mathematics instruction have documented positive outcomes in terms of students' problem-solving skills, creativity, and attitudes and beliefs regarding the study of mathematics. However, despite these promising results, problem posing in mathematics instruction has…

Mathematical problem-solving is a core content of primary school education. Therefore, it is necessary to provide all students with a meaningful way of acquisition of problem-solving skills. The objective of this research was to verify the effectiveness of a problem-solving routine based on the Pólya's model and the use of cognitive strategies…

This article presents the natural disaster and how it affects children over the world. When there is a natural disaster occurring such as hurricanes, tornadoes, flooding, it can affect not only the family but the children as well. The children are often left to relocate, live with other family members, or separated from their parents. Natural…

Children with intellectual disabilities experience well-documented challenges in the development of problem-solving, particularly related to mathematical word-problem solving. Such challenges are related to both linguistic and conceptual skills. While interventions to assist children in developing conceptual skills are well reported, linguistic…

The development of children's lie-telling abilities is considered to be a social and cognitive milestone. While occasional lying is developmentally appropriate, the use of frequent, antisocial lies as a maladaptive problem-solving mechanism can indicate behaviour problems. Since lying is often considered a moral transgression, researchers should…

Although anti-bullying programs often include a component that focuses on strengthening teachers' abilities in identifying and addressing bullying, it is not clear which bullying situations teachers find difficult to address and what type of support is needed. In the current qualitative study, we investigated what teachers considered difficult…

This study's purpose was to investigate effects of 3 intervention approaches for building working memory (WM) and improving word-problem solving (WPS). Children with mathematics difficulties (n = 240; 7.51 years [SD = 0.33]) were randomized to 4 conditions: a control group, general WM training with contiguous math practice, WPS intervention…

The purpose of this study was to explore the efficacy and acceptability of problem-solving consultation for homeschooling families with children who exhibited externalizing behavior problems. Three families participated, with multiple siblings participating from each family. Six children were male and 1 child was female. Children's ages ranged…

This study's purpose was to investigate effects of 3 intervention approaches for building working memory (WM) and improving word-problem solving (WPS). Children with mathematics difficulties (n = 240; 7.51 years [SD = 0.33]) were randomized to 4 conditions: a control group, general WM training with contiguous math practice, WPS intervention…

Elementary school children (ages 7-11) struggle to understand mathematical equivalence, a foundational prealgebraic concept. Some manipulations to the learning environment, including well-structured nontraditional arithmetic practice alone, have been shown to improve children's understanding; however, improvements have been modest. The goal of…
