Make rubric easier to use

We got feedback from multiple trainees that the time allotted to reading the rubric before practicing teaching the second time was not enough. They also shared that they were unsure of how to use the rubric, practically, that they wished it was a fillable template.

I think better instructions /easier use would also help with the timing issue.

Start by reviewing the existing rubric and the trainee feedback described in the issue. Clarify the needed instructions and fillable-template format, then confirm that the result addresses both rubric usability and the time available before the second teaching practice.
