Validation and Evaluation of an Instructional Material for Teaching English Grammar

This study aimed to validate and evaluate an instructional material for teaching grammar, focusing on content validity, student performance, and suggested improvements. Using a mixed-methods design, the study involved fourth-year English majors and master teachers at Batangas State University–ARASOF Nasugbu Campus. Data were collected through validated surveys and analyzed with weighted means, rankings, and t-tests. The instructional content showed moderate validity (mean = 3.08), with logical structure rated highest (mean = 3.67). However, visual appeal, activity relevance, and opportunities for critical thinking needed improvement. Most respondents demonstrated greater knowledge of grammar on the post-test. Suggestions included enhancing clarity, engagement, and alignment with learning objectives. The material had a positive influence but needs more development to better motivate learners and address diverse needs.
