According to businesslistening.com, Attentive Listening means thinking and acting in ways which connect you with the speaker. It is important for the teacher to fully listen to students and understand what they are saying. In addition, it is equally important for students to actively listen to each other and not zone-out in class.
In general, I think it is best to focus on authentic listening that appeals to the students' interests. If you are teaching young adults, then TV shows or movie clips might be interesting for them. If you are teaching businessmen, it might be better to show clips of meetings or presentations from Ted Talks. Then, discuss the listening or have an activity to check comprehension.
I hope that helps!
