Hi Allan,
Thank you for your great lectures. I'm so happy to have you as my teacher for online TESOL course.  
I just finished quiz for module 2 and have a question about number 1. The question was about basic blackboard rules.
When it comes to the basic blackboard rules, I learned from the video as below.

   1. Write in a straight line, clearly, and large enough for everyone to see.
   2. Maintain good posture.
   3. Stand to the side
   4. Speak while writing
   5. Use different colors

I picked 'Maintaining eye contact with students' as my answer to the question.(The question was finding one answer which doesn't belong to basic blackboard rules.)
Is 'maintaining eye contact with students' basic blackboard rule? I would appreciate if you explain about it.

Thank you.

Sincerely,
Hyelee Kim
