Based on my observations, the learning materials used by my teacher include textbooks, PowerPoint presentations, and occasional references from various sources, including various books and videos downloaded from YouTube. For innovation, she incorporates photos and videos so that students do not feel bored during class. This eclectic approach aims to enhance the lesson content delivered to students. The teacher uses books as the main reference to provide instructions and materials. Not only that, teachers also use several different books that can be combined and complement each other to enrich the learning content.
