However, empirical evidence among Vietnamese primary school students remains limited.<br> <strong>Objectives.</strong> This study assessed the effects of an 8-week chess training program delivered through a blended learning approach on novice learners&#39; cognitive functions and academic outcomes.<br> <strong>Methods.</strong> Utilizing a quasi-experimental design, 62 primary school students (Grades 4&ndash;5; mean age &asymp;10.6 years) were randomly assigned to an experimental group (n=32) and a control group (n=30). The experimental group received weekly 60-minute chess sessions combining face-to-face instruction with computer-mediated activities, covering chess fundamentals, tactics, endgame techniques, and opening principles. Pre- and post-intervention assessments measured academic performance via the School Performance Test (SPT), attention (short-term and minute-focused), and memory. Data were analyzed using one-way ANOVA, t-tests, and Pearson correlation analyses.<br> <strong>Results. </strong>The experimental group exhibited significant improvements in SPT scores (6.21 &plusmn; 0.34 to 8.02 &plusmn; 0.42; F=6.314, p=0.021) and short-term focused attention (45.34 &plusmn; 3.67 to 69.98 &plusmn; 4.12; F=4.897, p=0.042). Minute-focused attention (11.32 &plusmn; 1.45 to 17.23 &plusmn; 1.78; F=5.427, p=0.033) and auditory word memory showed marginal gains, whereas changes in literary creativity and digit memory were insignificant.<br> <strong>Conclusion. </strong>The findings indicate that blended chess training substantially enhances primary students&#39; specific cognitive skills and academic performance.</div> Cognitive Enrichment, Blended Learning Approach, Attention Span Development, Memory Retention Strategies, Academic Performance Enhancement 0 0 http://aassjournal.com/browse.php?a_code=A-11-2051-7&slc_lang=en&sid=1 Thi Huong Pham 100319475328460017042 100319475328460017042 No Hanoi University Of Physical Education and Sports, Ha Noi City, Vietnam Chanh Thuc Dao dcthuc@agu.edu.vn 100319475328460017043 100319475328460017043 Yes An Giang University, Vietnam National University, Ho Chi Minh City, Vietnam
