This study assessed knowledge and awareness of developmental dyscalculia among education professionals in the UK, Italy, Vietnam and South Africa, using the newly developed Dyscalculia Knowledge and Awareness Scale (DKAS). In total, 1323 educators responded to the DKAS as well as questions relating to their job roles, level of experience, and training received in supporting pupils with dyscalculia and dyslexia. Overall, most educators were familiar with the concept of dyscalculia, but only 33% reported that they had a clear idea about it. Responses to the DKAS also revealed several knowledge gaps and misconceptions. Our study also documented the low availability of training in dyscalculia, with most educators not receiving any relevant training. Higher levels of education, working in specialist inclusion and support roles, and access to relevant training were positively related to knowledge and awareness of dyscalculia. These findings have important implications for research, teacher education and education policy.

Objectives: Depression affects 23.3% of Thai and 15.2% of Vietnamese health science students, rates that exceed the global average of 4.4%. This study compared the causal models of mental health literacy and helping behavior toward individuals at risk of depression between these 2 groups.Methods: This cross-sectional study was conducted from April 2023 to October 2023 and included 422 students from Thailand and Vietnam, who were studying medicine, nursing, psychology, and physical therapy. Stratified random sampling was used to select 211 students from each country. Data collection was performed using a Likert scale, which showed total-item correlations ranging from 0.24 to 0.83 and Cronbach’s alpha values between 0.74 and 0.86. The data were analyzed using a structural equation model.Results: The causal models were consistent with the empirical data. The helping behavior of students toward peers at risk of depression was significantly influenced by their mental health literacy (effect size [ES], 0.91). This influence was also mediated indirectly by self-efficacy (ES, 0.18), positive attitudes (ES, 0.29), and social support (ES, 0.77). Collectively, these factors accounted for 83% of the variance in helping behavior. Social support had a more pronounced effect on mental health literacy among Vietnamese students than among their Thai counterparts (ES, 0.46 vs. 0.27, p<0.05). Conversely, positive attitudes had a stronger influence among Thai students than among Vietnamese students (ES, 0.17 vs. 0.01, p<0.05).Conclusions: The causal models of helping behavior among Thai and Vietnamese health science students exhibited no significant differences. However, improving mental health literacy is crucial, as it significantly impacts helping behavior.

Several cross-sectional studies have suggested that the transparency of the number-naming system of East Asian languages (Chinese, Japanese) facilitates children's numerical development. The Vietnamese number-naming system also makes the base-10 system very explicit (eleven is "mười một," literally "ten-one," and thirty is "ba mươi," literally "three-ten"). In contrast, Western languages (English, French) include teen words (eleven to sixteen) and ten words (twenty to ninety) that make their counting systems less transparent. The main question addressed in this paper is: To what extent does a language's number-naming system impact preschoolers' numerical development? Our study participants comprised 104 Vietnamese and 104 French-speaking Belgian children between 3½ and 5½ years of age, as well as their parents. We tested the children on eight numerical tasks (counting, advanced counting, enumeration, Give-N, number-word comparison, collection comparison, addition, and approximate addition) and some general cognitive abilities (IQ and phonological loop by letter span). The parents completed a questionnaire on the frequency with which they stimulated their child's numeracy and literacy at home. The results indicated that Vietnamese children outperformed Belgian children only in counting. However, neither group differed in other symbolic or non-symbolic abilities, although Vietnamese parents tended to stimulate their child at home slightly more than Belgian parents. We concluded that the Vietnamese number-naming system's transparency led to faster acquisition of basic counting for preschoolers but did not support other more advanced numerical skills or non-symbolic numerical abilities. In addition, we extended the evidence that both transparent number-naming system and home numeracy influence young children's counting development.
