For this purpose, we selected 6 open problems suitable for learning mathematical reasoning and five 3rd grade middle school students as participants who expected to participate in 6 lessons of discussion-based learning of mathematics using smartphone applications. From the analysis of the 6 lessons, we found the following results. First, attending the lessons of discussion-based learning of mathematics using smartphone applications makes students more interested in mathematics and changes their mathematics learning attitudes positively. Second, the lessons of discussion-based learning of mathematics using smartphone applications facilitate students’ mathematical communication with the help of various communication methods using many functions of smartphone applications. Third, the lessons of discussion-based learning of mathematics using smartphone applications provide teachers with a teaching-learning environment where teachers can easily give their students consultations about mathematics learning or daily life. rv:
