Considerations:
Who is part of your presentation team?
What are the cross-curricular connections?
What is the "right length" of your video conference?
How do your engage students in your presentation?
Ways to make a connection to the school site
Have school introduce their class (grade level, subject area, school mascot, etc.)
Show a map (if computer capable use google maps) of where you are at and the school is at.
Other idea?
Engaging tips during the lesson
If you ask a question have the teacher select a student to answer. (You can go by color of shirt, front row, etc. but easier and quicker to have teacher do the selection.)
If you ask a question ask students to partner to discuss and then share answer
If you ask a question and want to get a group response of understanding have them give a visible gesture. Example thumbs up for understand - sideways for not sure - down for don't get it.
Leave time for questions at the end of the lesson.
If possible include student movement within lesson.
