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…

An accurate assessment of cognitive abilities in populations that differ from the majority in cultural and linguistic characteristics is one of the main challenges in cognitive testing. Previously developed methods for assessment of the validity of cognitive scores in individuals with diverse backgrounds, such as the Culture-Language…

Reading comprehension is a fundamental skill to be developed from the early stages of reading acquisition and it is essential for both formative and personal learning. This study examines eye-tracking as a useful and complementary tool in the assessment and improvement of implicit reading comprehension. The aim is to understand the role of…

The main objective of this study is to assess the Spanish literacy competence of students enrolled in bilingual and trilingual programs by analyzing the developmental process and evolutionary course of reading during the first cycle of Primary Education. This analysis aims to determine whether the reading skills in Spanish of students in…

The aim of this study is to investigate the impact of technology-supported mathematical modeling method on the mathematical skills of a fourth-grade student with Mathematical Learning Disabilities. The study group consists of a fourth-grade student. It was discovered that the student lacked numerical and logical skills compared to other students.…

While symbolic number processing is an important correlate for typical and low mathematics achievement, it remains to be determined whether children with high mathematics achievement also have excellent symbolic number processing abilities. We investigated this question in 64 children (aged 8 to 10), i.e., 32 children with persistent high…

This study examined the factor structure of executive control throughout elementary school, as well as associations between executive control abilities in preschool and elementary school. Data were drawn from a longitudinal study of executive control development in a community sample of children (N = 294; 53% female, 47% male) oversampled for low…

Difficulties in monitoring reading comprehension result in poor comprehension. One key aspect of monitoring is metacomprehension, which refers to one's awareness of one's own reading comprehension. Previous studies have observed difficulties in metacomprehension among the deaf or hard-of-hearing (DHH) population. This study aims to determine…

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…

Two case studies of Australian primary school students tracked changes in their data interpretation and representation over three years. Students were engaged in predictive reasoning tasks based on their interpretation of a data table showing temperature change over time. Students' explanations and graphical representations were collected at the…

Purpose: This exploratory study aimed to investigate the potential impact of sentence-level comprehension and sentence-level fluency on passage comprehension of deaf students in elementary school. Method: A total of 159 deaf students, 65 students (M[subscript age] = 13.46 years) in Grades 3 and 4 and 94 students (M[subscript age] = 14.95 years) in…

Background: Teaching vocabulary may be an effective way to address poor reading comprehension. However, it is unclear how many words or word families a school aged child with poor vocabulary would need to learn to meaningfully impact comprehension. This study provides estimates of vocabulary size for children with differing vocabulary achievement…

This article assesses nutritional intake and adequacy in children with autism spectrum disorder (ASD), subdiagnostic autistic symptoms and children with typical development (TD). In total, 77 children diagnosed with ASD, 40 with subdiagnostic autistic symptoms and 333 children with TD were assessed. A validated food frequency questionnaire was…

Despite the lasting interest towards the relationship between intelligence and creativity, comparably less attention is paid to its age-related changes. Our paper considers the organization of fluid intelligence and psychometric indicators of creativity and is based on the experimental data obtained for children aged 11 (n = 99) and for young…

The study examines whether the average performance of the population with dyslexia in a working memory measure can be inferred dimensionally from the characteristics of the typical population. Specifically, we focused on Associative Phonological Working Memory (APWM), an ability that we predicted being impaired in dyslexia due to the relationship…
