The ACM approach originated from Kelly's (1955) personal construct psychology and Ausubel's (Ausubel, 1968; Ausubel et al., 1978) ideas of meaningful learning (Adey, 1992). Kelly argued that each person constructs a representational model of the world, composed of a series interrelated personal constructs, or tentative hypotheses about the world, with which past experience is described and future events are forecast (Bell & Gilbert, 1996). Ausubel's (1968) influential statement that "the most important single factor influencing learning is what the learner already know" (p. vi) has generally accepted by the science education community. Meaningful knowledge is seen as growing from and on existing knowledge.
