Learning & Communication plays an important role in our life, to have an effective communication we must be a good listener, observer and performer. First of all we must listen what other person tells and observe the important points from their speech to give progress. We may have some doubts, but we must wait for some time until the speech is finished and clarify our doubts after it.
While listening classes we must listen our teacher and observe what s/he teaches to us. If we listen the class and observe the lesson well, we will understand it properly. We must learn the lesson at the same day of teaching which will help us to understand the concept very well.
If we have any doubts with our lessons, we can ask it to our teacher after finishing his/her lessons and clarify our doubts. If we ask our doubts in between the communication we may misunderstand the lesson and ideas, so we must listen and observe the conversation and ask our doubts after finishing it. This kind of process is the best way for effective learning and communication.
What do you think about this kind of effective learning system? Surely it will give more benefits to both teachers and students and we can learn the lessons easily and effectively using this method.

That style of classroom would be my favorite. But still, this is a classroom, highly suited for introverted people. But the extraverted people need discussion and exchanging ideas in the open. Introverted person can easily make the learning in his head, as he listens, but for extraverted person it is easier, to speak out loud to clarify. And that could mean misunderstanding the whole class because of that.
The other point is, how many people stay behind in class to ask questions? I am in university, and here the answer is around 5%. In high school it was closer to 0%.
Nice suggestions!
