Teachers’ Self-Efficacy in Dyscalculia: Development and Psychometric Validation of a New Scale

Posted on by

The aim of this study is to develop a valid and reliable scale for measuring the self-efficacy of primary school and mathematics teachers regarding dyscalculia. Grounded in Bandura’s Social Cognitive Theory, the study followed established scale development procedures. In the initial phase, a pool of 42 items was generated to assess teachers’ self-efficacy regarding dyscalculia. The items were reviewed by a panel of seven experts in the fields of psychometrics, mathematics education, special education, and psychology to ensure content validity.

The findings indicate that the DSES is a valid and reliable instrument for assessing teachers’ self-efficacy regarding dyscalculia.

Keeping my kids as my main focus. When things got tough, I chose to homeschool. It started with one child, then two, and eventually three of my four children. That experience taught me how to truly support them and how to teach in a way that made sense for how they learn.
My strong entrepreneurial abilities, which I attribute to my neurospiciness. I have learned to lean into how my brain works instead of trying to fit into a traditional mold, and that has been a huge advantage in building my business.

What advice do you have for folks who are early in their journey in terms of how they can best develop or improve on these?

Build your support system intentionally. Surround yourself with people who encourage you, challenge you, and remind you of your vision when things feel hard.

Roll back inequality precipitated by mathematics exclusion

Posted on by

Mathematics is applied in education policy, economics, and cognitive sciences as a reliable health indicator of an education system and treated as a harbinger of systemic conditions.

South Africa ignominiously ranks near the bottom in the Trends in International Mathematics and Science Study.

In 2023, grade 9 mathematics and science learners scored 397 and 362, respectively, which is well below the international average of 500.

Average scores mask severe inequality, and in 2023 Quintile 5 and Quintile 1 schools scored 492 and 307, respectively, which is tantamount to a two- to three-year learning backlog for the poor.

Structural constraints in South Africa are real. In 2023 South Africa employed about 455 000 teachers, deployed in over 24,580 schools (about 2 500 of which are private schools).

How Common Is Dyscalculia in Children Today

Posted on by

When examining how common is dyscalculia, research suggests that it affects approximately 3 to 7 percent of school age children. This places it among the more prevalent learning disabilities, alongside other learning disorders such as dyslexia. According to the diagnostic and statistical manual published by the American Psychiatric Association and American Psychiatric Publishing, dyscalculia falls under the category of a specific learning disorder with impairments in mathematics.

The exact prevalence can vary because developmental dyscalculia depend on how diagnostic criteria are applied across studies and educational systems. Some children may not be formally identified, especially if their difficulties are mistaken for general learning difficulties or lack of practice in math tasks.

Compared to other disorders, dyscalculia often receives less attention, even though its impact on mathematical reasoning and basic math skills can be significant. Students with dyscalculia may struggle silently in math class, particularly when expectations increase with grade level.

Dyscalculia Explained: Understanding Math Difficulties in Children Poster Guide

This free printable PDF explains dyscalculia in a simple, accessible way. It helps parents, carers and professionals understand what dyscalculia is, how it affects children, and what support can make a real difference. Dyscalculia is a specific learning difficulty with numbers and maths, often described as “maths dyslexia”, where children struggle to understand number concepts, quantity, and basic calculations. The poster outlines common signs of dyscalculia in children, including difficulties with counting, number recognition, remembering maths facts, telling the time, handling money, and following steps in maths tasks. It also highlights emotional impacts such as frustration, anxiety about maths, low confidence, and avoidance of learning.
