Hi Gil, to your point I too have found that student voice inflection, tone, eye contact, monitoring the conversation, etc. all help instructors keep a pulse on the classroom or lab. Additionallt, I often have students paraphrase lesson content to each other, or engage in "mini" related hands-on activities during the presentation of a new topic or application.
Thanks for your observations!
