There is so much that I can take from this particular lesson. For starters, there is value on the importance of questioning by both instructors and students. Teachers encourage dialogue and student openness by purposely creating a "safe space" where the thoughtful responses and questions of students AND their peers are welcome.
How information is presented also plays a vital role in how information is received. Good communication skills in both verbal and non-verbal ways could make or break the relationship of learning that an instructor has attempted to build/create.
As a side note: I was a little disappointed by the video on Investigative Questioning. While I appreciate the material, I found it very difficult to focus on the topic given the number of "Ummms" between thoughts. She used "umm" no less than 10 times in a presentation no longer than 2 minutes. I am surprised that this program would use a video like this. I imagine this young lady created this video as part of a class requirement in her teaching education journey.
