During the button dichotomous activity, I improved my communication competency. I can ask and respond to questions to be an active, supportive listener. We need to classify different kind of buttons into different branches to recognize each different button, during the process my teammates and I need to have a close discussion to get the same opinion, we respect and listen to each other’s opinions. Also I can understand and share information about a topic of interest in a clear, organized way. In discussions and conversations, I help to build and extend understanding by naming for different buttons, different names can help us to classify that specific button by knowing what are their feature.
