This experimental study aimed to investigate the application of Bloom's taxonomy in teaching grammar, specifically English tenses, at IUH. The researchers aim to enhance the teaching and learning process of English tenses by incorporating higher-order thinking skills into the activities. Two groups of students, DHAV18A (n=42) and DHAV18B (n=45) were involved in the study. After teaching the English tenses chapter in the grammar course, the views of the students were surveyed regarding the self-study section and in-class activities that utilized a high level of Bloom's taxonomy. Additionally, students' scores on a test were analyzed, revealing that 90% of students were able to answer basic questions correctly, while 80% were able to answer difficult questions that required the application and creation levels of Bloom's taxonomy. The study also outlines the specific steps taken to adapt the taxonomy, including the identification of specific verbs and cognitive processes related to teaching English tenses. The adapted taxonomy is then used to design a set of grammar activities for each tense. Finally, the researchers conducted a pilot study to evaluate the effectiveness of the activities in terms of student engagement and learning outcomes. The findings suggest that the adapted taxonomy can be successfully applied in designing grammar activities for teaching English tenses, leading to improved student engagement and learning outcomes. The study concludes with recommendations for further research and implications for language teaching
