Interaction Jesus preached to multitudes, but He also interacted one on one and in small groups. He skillfully asked questions and gave wise answers. His questions often drew the truth out of people, causing them to discover the truth themselves and say it with their own lips. This is extremely effective both with friendly and hostile company. When people reason through coming up with answers, they tend to remember them better.
Questions are also effective at exposing hypocrisy and error when skillfully framed.
Story Telling Jesus used stories of real events, both historical and current. Stories often hold interest and present abstract concepts more effectively than a simple statement of the point of the story. Parables Parables are probably Jesus' most famous teaching techniques. Parables have the paradoxical effect of both revealing truth for whom the message is intended and hiding it from those who don't want to hear it. Jesus would often tell a parable in public to multitudes, then explain its meaning in private to his friends and disciples.
