火成岩の多様性と学習の意義 : 花崗岩に類似した岩石の識別
Significance of Learning the Diversity of Igneous Rocks: Focus on the identification of granite-like rocks
長谷川 礼次
Abstract
Igneous rocks are divided by the difference of constituent mineral and texture such as equigranular or porphyritic. In junior high school, it is required to observe the various volcanic and plutonic rocks and to understand that differences in their textures are caused by differences in their formation process. Although students of science teacher training course can correctly identify typical igneous rocks, but they often cannot identify rocks in the boundary region or untypical appearances. This study clarified that the beginners tend to identify igneous rocks based on uncertain features such as color and presence of magnetism rather than the combination of minerals.
