Abstract
Theory plays an important role in education. It is the baseline premise that evokes further investigation, and through valid study, the status of a proposed explanation can be changed from conjecture to research-based fact. This chapter poses three theoretical frameworks. The Bio-Ecological Theory/Human on Human Development posits that a child's physiological development combines with consistent exposure to his/her environment throughout the early stages of life to play a significant role in a child's overall development. The Social Model Theory on Disability suggests that society's understanding of what is considered a “disability” along with certain perceptions and biases about immigrants can inhibit effective fulfillment of learning needs on behalf of children from Culturally and Linguistically Diverse (CLD) background.
