The present study aims to find out how the students made use of game records in their tablet devices when reflecting on their games and what was going on in their discussion. By analyzing their utterances in their team conferences, it is revealed that the numbers and ratios of the returns of the ball recorded in their tablet devices were utilized as the viewpoints of their discussion and they facilitate their discussion. It is also thought that team conferences give the students the opportunity to learn collaboratively and that the utterances which accept their teammates and the ones which ask their teammates questions enrich collaborative learning.
