Teachers need to evaluate teaching and learning materials because the quality of instructional materials directly influences the effectiveness of the teaching-learning process. Textbooks, workbooks, digital resources, audio-visual aids, worksheets, and online learning platforms are designed to help learners achieve specific educational objectives. However, not all materials are equally suitable for every classroom or group of learners. Evaluation enables teachers to determine whether the selected materials are relevant, accurate, engaging, and capable of meeting learners' academic and developmental needs. One of the primary reasons for evaluating materials is to ensure that they are aligned with the curriculum and learning outcomes. Materials should support the prescribed syllabus, educational standards, and instructional goals. If they fail to address the intended objectives, students may not develop the required knowledge and skills. Therefore, teachers must assess whether the content is appropriate for the course and grade level. Evaluation also helps teachers determine the suitability of materials for learners' age, language proficiency, cultural background, interests, and learning
