This study investigates the impact of implementing the Computer-Assisted Language Learning (CALL) approach using the Nearpod platform to improve phrasal verb vocabulary among adult learners at Centro de Matemáticas e Idiomas Segura (CMI Segura) in San Isidro de Alajuela during the third quarter of 2024. The study involved 25 adult participants and employed a mixed-methods approach, including a pre-test, two observation checklists, a questionnaire, and a post-test. The pre-test results highlighted a need for focused practice in phrasal verbs, confirming initial knowledge gaps among learners. Following the intervention, the post-test demonstrated a notable improvement, with 75% of participants meeting the targeted proficiency level. Observations confirmed high engagement and autonomy, with the Nearpod platform facilitating immediate feedback and interactive learning. The results suggest that Nearpod, as a CALL tool, effectively enhances engagement, promotes vocabulary acquisition, and supports diverse instructional approaches. The study highlights the importance of contextual and autonomous learning in mastering complex vocabulary, aligning with recent CALL research. Recommendations include incentivizing attendance, fostering student autonomy, introducing phrasal verbs prior to CALL-based activities, and expanding sample size in future studies to strengthen findings.
