Students learn in different ways depending on their individual learning styles and sensory preferences. Some students learn best visually, others auditorily, kinesthetically, or tactilely. Teachers should identify each student's preferred learning style and incorporate activities that appeal to different modalities, such as visual displays, verbal instructions, physical activities, and hands-on projects. Psychologist Howard Gardner also theorized that people have at least seven distinct intelligences, including logical, visual, kinesthetic, musical, interpersonal, intrapersonal, and linguistic abilities, and teachers should design lessons to engage students' varied intelligences.
