Piaget’s Theory
Piaget’s theory is mainly based on the idea that individuals acquire knowledge on their own, individually, without the help of anyone (Bruner, 1997; Forman, 1992; Tappan, 1997). For Piaget (1983, 1985; Piaget & Inheler, 1969), the individual’s action and its coordinations are regarded as the main factor responsible for his/her own growth, cognizance and understanding. Put differently, his theory includes the concept of psychogenesis ( Bennour & Venoche, 2009), which explains his belief that development takes place in a relatively natural and instinctive fashion (Piaget, 1969, p. 59), that is to say, that development takes place from within and not from without (as something social or cultural).

Genetic. A development perspective is essential in understanding psychological issues, as is the case of Piaget’s mental operations and/or formal operation, (Inheler & Piaget, 1958; Piaget, 1947), and of Vygotsky’s (1978) symbolic operation, like to tie a knot on one’s finger for an individual to remember to perform a task in the near future (i.e., mediated memory). Vygotsky (1978) states: ”…we are advocating the developmental approach as an essential addition to experimental psychology” (p. 61, emphasis added).
2.Dialectical approach. This approach is related to metatheory in developmental psychology. Both Piaget and Vygotsky agreed on this approach, which is that “psychological development involves a continuous stream of engagement between distinct, but interdependent, functions or processes, such as assimilation/accommodation” in Piaget’s theory (1952/ 1980, 1985) and internalization/externalization in Vygotsky’s thinking (1962, 1978). Strictly speaking, it focuses on the study of interrelationship and
