Individuals learn best when the material is appropriate to their developmental level and is presented in an enjoyable and interesting way
Because individual development varies across intellectual, social, emotional, and physical domains, achievement in different instructional domains may also vary
The cognitive, emotional, and social development of individual learners and how they interpret life experiences are affected by prior schooling, home, culture, and community factors
Early and continuing parental involvement in schooling, and the quality of language interactions and two-way communications between adults and children can influence these developmental areas
Awareness and understanding of developmental differences among children with and without emotional, physical, or intellectual disabilities, can facilitate the creation of optimal learning contexts
