Instructional material is known as teaching-learning material (TLM). It’s any material that a teacher uses to make their classroom instruction more thorough and successful. Human or nonhuman resources (materialistic things like libraries, computers, books, etc.) can be used as teaching-learning materials. The instructor or student can quickly purchase or create teaching and learning materials.
There are three categories of teaching-learning resources.
Audio Aids: These aids stimulate the auditory senses, which enhance learning. Because it focuses on pronunciation, it aids language learning and Learning Management System.
Visual Aids: By stimulating the visual organs, these aids assist learning. Visual aids include lines, patterns, vibrant imagery, and brilliant colours. These are visually appealing and educational.
Audio-Visual Aids: These audio and visual aids are combined into one. They use the pupils’ hearing and visual organs to help them comprehend what they are learning.
