This study has found evidence that the use of DSLM indeed facilitates the conceptual change
of heat transfer among students. Careful examination of the process involved in the conceptual
change reveals how students progressed from preknowledge toward a more scientific view of the
concepts. Before the intervention, analysis of students’ beliefs concerning heat transfer showed
most of the students possessed only matter knowledge about heat, heat transfer, conduction, and
convection. None could describe the process of heat conduction or heat convection, or explain
when and why the substance would transfer heat via conduction or convection. After the
intervention, a series of six dual-situated learning events and one challenging situated learning
event successfully helped students reconstruct a more scientific view of heat conduction and
convection.
