How can you rebuild the new testament churches model of teaching?

First we need to identify what it looked like? Where can we look to see what how the Jewish believers in Messiah Jesus would have approached teaching and shepherding by the examples of Jesus and the practices of the Jewish people regarding teaching. Where can we go to confirm what we learn but to God himself and to his Spirit testifying to what we are hoping to do. I have my thoughts and the things God has shown me regarding how to teach as a pastor so as to make room for the spirit of God to teach and I will add those here later but first I want to hear what you think we can do to change things. What steps we can take to remove the corruption from the teaching practices of the family of God?
