Teachers' concepts of spatial scale: an intercultural comparison between Austrian, Taiwanese, and US-American teachers

In the science curricula of various countries, scale receives an important place in middle as well as in high school science education. This study explored scale concepts of inservice and preservice teachers from three countries, Austria, Taiwan, and the USA. Accuracy of scale concepts differed in the samples of the three countries. The Austrian and Taiwanese samples held more accurate concepts of scale than the U.S. sample. Inservice teachers had more accurate concepts than preservice teachers.
