发明名称 STUDY-AID THING AND STUDYING METHOD BASED ON POLARIZED LIGHT PRINCIPLE FOR STUDYING EFFICIENCY ELEVATION
摘要 PURPOSE: A learning assistance device and a learning method thereof are provided to remove the inefficiency of a learning process caused by a correct answer which exists in the same side where a problem exists. CONSTITUTION: A first polarizing film part(100) is detachably formed in a learning target part. A second polarizing film part(200) is arranged on the first polarizing film part. The learning target part is non-visually formed by orthogonalizing the first polarizing film part and a polarizing direction. The first polarizing film part sprays an adhesive material onto one side or the entire side.
