This study examined the effects of educational software (DENIS) and computer games on 6th grade students' vocabulary learning and strategy use. A quasi-experimental design was used with 68 students who received vocabulary instruction through DENIS software, computer games, or both over 9 weeks. Tests before, during, and after the intervention measured effects on vocabulary achievement, while a vocabulary learning strategies scale assessed strategy use. Results showed that both software and games positively impacted vocabulary learning. Strategy use, particularly compensation strategies, increased significantly. Male students used compensation strategies more than females. The study concluded that computer-assisted vocabulary instruction benefited learning and supported strategy development.
