Robert Tabachnick , and Kenneth Zeichner are program line potential science teachers how to cooperate their students go through the process of repugn one idea with anotherConceptual adjustment cases encyclopaedism involves changing one s conceptions in addition to adding new cognition to what s already there , says Hewson . Learning involves an interaction among new and breathing conceptions , and the outcome depends on the constitution of the interaction .
