The Figure 2 explains the flow chart of CAI creation processes in step by step. First, the researchers explain how
to use the CAI to the sample group students. Second, the researchers let the sample group students do a pretest
exam. Third, the sample group students learn the CAI. Forth, the sample group students do an exam in each lesson
of the CAI. Fifth, the sample group students do a posttest exam. And sixth, the researchers gather posttest scores in
order to find a learning achievement.
