I like that he's allowing the students to remain engaged in the lesson by interacting mentally with one another. Although; they're not physically interacting with one another they're working together to accomplish educational goals together. He's also teaching them to take turns and respect one another.  

1. To facilitate students writing, I will stop reading during the middle of the text, let students write out what might happen next and then post on the chat box. Or, to express students pro and con on certain situations, asking them to write out why they agree with or disagree with the ideas.

2. Even in math classes, I called students to read out loud about the questions to make sure that they understand what the questions were asking.

3. For cold calling realling dependends upon the situation and the pressure the students might face. I feel much comfortable to do cold calling when the answer does not reflect the level of understanding for not to embarrass certain students. On the opposite, during a small group where students know each other very well, I will do cold calling to make sure that the slow learners really understand the concept of the texts.

1. Do like Ben did and have a breakout session/rooms or put the in rountinly groups. A Balance I also, Like the idea on the one-on-one peer chat discussing class assignment\project

2. Give the student the assignment making sure their aware of the instructions attached, and have them to recite or ask (after they have read the instructions) if they have any questions on it or if there's anything I need to expand on. Also, motivate and encourage students on the importance on active reading and staying on top of their assignments and duties.

3. Yes, because I want my class and students to remain actively engaged at all time. Keeping them "present" in the moment. I remember my school days high school and college I had teachers that would just rommendly call me out but that also thought me a valuable lesson. To stay ready, to be engaged, do the work/study, and it also kept me on my feet. Be ready for the unexpected because learning is transformative. Which can be a very positive thing.
