Individuals differ from one another in many physical, mental, emotional, and behavioral characteristics. Some key individual differences include physical attributes, intellectual abilities, motor skills, emotional tendencies, interests and attitudes. Individual differences arise from variations in hereditary factors, environmental influences, maturation, hormone secretions, learning experiences, and more. It is important for teachers to recognize individual differences among students to provide tailored instruction appropriate for each student's abilities and needs. Teachers can address individual differences through ability grouping, curriculum adjustments, varied teaching methods, and specialized programs to help all students learn at their own pace. Exceptional students who significantly differ in mental, physical, or social traits may require modified instruction or special education services.
