School children often experience difficulty in mastering the concept of proportionality (Hart, 1981; Inhelder & Piaget, 1970; Noelting, 1980a, 1980b, 1983; Piaget, 1946; Vergnaud, 1980, 1983). Its development results from the quantification of a two-fold qualitative relation (lnhelder & Piaget, 1970; Sinclair, 1968). Vergnaud (1980) and Karplus, Pulos, and Stage (1983a, 1983b) have studied the distinction between two types of relationships (within and between) among variables, and Vergnaud and Ricco (1977) have observed the between comparison to be more “natural.”
