Abstract

The purposes of this study were to analyze the effect of a scaffold to help in understanding the principle of land and sea breeze through the convection current box experiment and to analyze the students' inference abilities and analogy abilities. For this purpose, the 60 elementary students who had not learned the principle of land and sea breeze were surveyed and analyzed. When using the scaffold to compare the movement of the incense smoke in the convection current box with that of the incense smoke on the outside of the convection current box, the rate of the students who correctly understood the principle of the land and sea breeze between the sea and the land was very low. The result shows that the scaffold used in this study do not help sufficiently in understanding the principle of the land and sea breeze through analogy and it is necessary to introduce a new scaffold for the elementary students to understand it.
