The purpose of this study was to investigate the effects of utilizing Gowin's vee diagram of experience
of producing process of Avogadro' s molecule theory to increase the creative inferable ability. One group
pretest-posttest was used in this study as an experimental design. Before draw up Gowin's vee diagram
of Avogadro' s molecule theory, few preliminary teachers have the knowledge about Avogadro's molecule
theory. after draw up Gowin‘s vee diagram, many preliminary teachers have the knowledge about
Avogadro's molecule theory is increased. Paper and pencil testing of Avogadro's molecule theory was
administered to investigate preliminary teacher's conceptual understanding and conceptual change before
and after the application of Gowin's vee diagram. The conclusion of this study are the Gowin's vee
diagram is more effective than the traditional teaching model, and after the application of the teaching
model(Gowin's vee diagram), the proportion of preliminary teachers hold perfect conceptions was
increased
