Pros

Cons
The summer program is very intense, which would be fine if you felt like the time was being used wisely. In the morning you will teach summer school, not the worst because it's only 1-2 hours of active teach. Except...the curriculum they provide expects you to teach a 90 minute lesson in 60 minutes, then move right on to the next one, never mind any gaps in understanding. They talk about then gloss over the importance of many things that go into being an effective teacher. Basically it does a lot of teaching based on data about certain teacher behaviors, but has no heart.
