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.
