Investigating Elementary Students에 Alternative Conceptions of Heat and Temperature

In this study, the contents of elementary school science textbooks related to 'heat and temperature' are analyzed and alternative conceptions ofi"heat and temperature" among students enrolled in grades 4, 5 and 6 are investigated. 259 students were selected from a elementary school located in urban area. The relationships between students' alternative conceptions and the content of elementary science textbooks are also examined. Students' conceptions are analyzed from their answers to a paper-and-pencil test. The typical alternative conception of "heat and temperature" held by students was follows. They think that "heat" is a material and "temperature" is value of heat amount. They can't distinguish between "heat" and "temperature". Their explanation of "heat and temperature" is focused on hot or cool sensation and other observable characteristics of a material. A textbook analysis indicated that contents on "heat and temperature" were organized without the viewpoint of particle motion theory. This may be one of the causes of students' alternative conceptions.
