We examined the effect on the listening side’s learning motivation in debate by using tablet terminals with synchronous CSCL for visualization of thinking. The following points became clear. 1. Listeners’ concentration is maintained at a high rate, concentrating on the speaker or the description on the screen. Aggressive behavior is increased, such as expressions of consultation and feelings about the discussion, while passive behavior is reduced. 2. The listening side hopes for a learning environment that visualizes thought, because it enables them to refer to the others’ opinions and convey their opinions to the others, and the usability of edutab. 3. The type of tool that the listeners use does not significantly make a difference to the number of comments.
