Interactive learning

[RachelMHansen]

I am trying come up with strategies for interactive learning. Based upon some readings, here is what I have so far:
Initiating conversation with students so that they can have the opportunity to speak, without the burden of initiating the conversation themselves.
Questioning students in order to “initiate a chain reaction of student interaction.”
However, this is what I am concerned that students getting bored with repeated questioning.
Also, I’m concerned about stating questions in a way that is either too simple (and thus insulting) or too difficult (and thus confusing).
How can I encourage interactive learning, while accommodating various levels of English proficiency?
