 note = {application, We gave linear algebra lessons to the fifth grade students as an elective subject and analyzed that to what extent students understood the linear algebra, judging from the result of questionaires and tests. It showed that they are good at the problems accompanied by calculations such as inverse matrix, simultaneous linear equation, and proper value problem and that, on the contrary, it is difficult to understand the abstract notion like linear space and linear map.},
