TY - JOUR AU - Molnár, Gyöngyvér AB - Student academic achievement is a key component of learning outcomes and education effectiveness. Reading comprehension is among the most crucial skills for learning in all subjects. A major component of reading comprehension is vocabulary knowledge, which is essential for mastering different subjects. The aims of our research were to develop a computer-based training program for subject-specific native academic vocabulary development among primary school students and to determine the efficacy of the intervention. A total of 2,860 hungarian students were involved in the research. The academic vocabulary training program was developed on the eDia platform and included a pretest, a four-phase training program and a posttest. The experimental students’ performance significantly improved, and their outcomes showed higher results than the control group through regular school education. In the intervention group the effect size was high (d = 1.220) among the low achievers who developed more than one standard deviation below average on the pretest, indicating improvement of more than one standard deviation as an intervention outcome. The results confirmed the potential of online vocabulary training programs and highlight the importance of diagnostic assessments and interventions. The use of technology largely enhances the development process, tailored to the needs of individual students.
