This is where we carry out the plan from the first step. This can take a lot of different forms depending on where the student is and what they need.

The "Help, I'm Stuck!" Meeting

This is a common type of meeting when the student is stuck on something they’ve been working on and are trying to figure out how to get things working again. This is a great opportunity to pair program on debugging skills, walking through the problem solving steps together. Sometimes as a mentor you’ll know what the problem is right away, and sometimes you’ll be just as stumped as the student, but either way walking through a debugging process is very helpful. The process might look like this:

1. Have them describe their understanding of the problem and what they’ve tried so far to resolve it.
2. Confirm the problem together and have them walk through recreating it slowly to confirm that what they think is the problem is actually the problem (it often isn’t).
