Abstract
“Fipped Classroom” is a teaching method that learners prepare their lesson by watching a video about the lesson at home and they confirm learning contents and discuss about it at school. In this study, we conducted a flipped class in arithmetic: direct proportion and reverse proportion in 6th grade of elementary school. For verifying effects of the flipped style practice, learners’ video viewing logs, notes at home, pretest and posttest were analyzed. Consequently, there were four findings. 1) Even lower ranked learners could achieve a certain result. 2) Learners’ viewing activities were different between their ranks. Higher ranked learners exceeded viewing time and they watched videos little by little to understand the contents well. 3) The higher ranked learners took notes in detail. The lower those tend not to write their calculating process and reflection. 4) Among the lower ranked learners, those who achieved a higher rank at posttest wrote their notes in detail both at home and at school.
