There is now a wealth of video clips on You Tube. Just type in ESL Lessons to get more traditional instructional videos.
Another way you could do it, is show a clip on a topic of interest to a student. This real life instruction has been proven to enhance learning and motivation.
Use a video about 2 minutes long. Before viewing, do some prereading activities.
First use still pictures from the video and ask your student to predict language and content. Find something for your student to read that introduces the content on the video. Discuss vocabulary which you think the student may not know. Also, tell the student why they are watching the video-- to learn workforce skills etc.
