Answer:
He needs to improve his body language when listening.
Explanation:
Jin does make connections to prior knowledge, as mentioned in the scenario. It is shown in the portion: "Jin contributes meaningful ideas, support them with data, and makes connections to other ideas." Therefore, he does not need to attempt to make any more connections, since he is already doing so.
Jin also asks for clarification. Although it is not directly stated in the scenario, by engaging in the formal discussion, he seems to understand the concept of it, therefore leading him to give out meaningful ideas. And, even though he doesn't, he would probably ask others for clarification to brainstorm more ideas.
Jin uses language that is appropriate to the topic. This is also indirectly stated, but by actively contributing to the conversation, he would probably use language that is appropriate and grammatical in order for others to acknowledge his idea.
However, the scenario mentions that when it is not his turn to speak, he would slump down in his chair and rests his hand on his hand. Although the body posture is appropriate when he is speaking, however, when engaging in a discussion, they should maintain the posture throughout the discussion, which shows the other peers that they are not only actively speaking, but actively listening as well.
Therefore, Jin needs to improve his body language when listening.
Hope this helped!
