Hi Richard,
Try greeting each student as he/she enters the classroom each time the class meets. If you can ask each student one question that they can respond to easily. It can involve the weather, sports, local event, school happening, etc. Point is you are talking with each student in a different setting than the formal class. You will be surprised at how quickly you will develop your skills of interaction. Before you know it you will be much like the professor in the video.
