Abstract

This research focuses on Arabic language teaching to Grade VII Mutawassitah students at Maahad Attarbiyah Lilulumidiniyah High School. The study identifies the main obstacle for students as the lack of vocabulary knowledge, attributed to the use of general and uninspiring learning media such as PowerPoint and picture cards.

Notably, the second cycle showed a significant increase, reaching a 100% post-test observation score. The findings highlight the effectiveness of crossword puzzle learning media in enhancing vocabulary understanding among Arabic language learners. Highlights: Lack of vocabulary knowledge: The research identifies the main obstacle faced by Grade VII Mutawassitah students at Maahad Attarbiyah Lilulumidiniyah High School in learning Arabic language is the insufficient grasp of vocabulary.
