The class that I have observed so far is a Special Ed class that serves as an extra support for the students English classes. As a result, the class structure is quite straight forward. The teacher is helping the students to understand concepts better while, at the same time, helping them to complete their homework.
Some ways the teacher tried to engage the students is by reading out loud to them as they follow along. She pauses as she reads in order to define difficult words or talk about a particular interaction in the book.
She is also excellent at helping them navigate the online aspect of their assignments, making suggestions and giving feedback as they progress.
For the most part, the students are well behaved, but I have noticed that when the teacher allows one or more of them to speak about something completely not related to the classroom, they all interact and then end up being better focused when they get back to the project at hand. As if providing a brief intermission helps them all find their focus again.
