Reflection: Trust and Respect Valentine Mailbox - Build and Test - Part 2 - Section 5: Day Two: Mailbox Test and Evaluation


The evaluation form is a wonderful way to introduce the idea that we can write suggestions to help a classmate fix their mailbox, rather than just say it doesn't work. Also, the comment form provided a way for students to share what they did like about the mailboxes.

The 'comment section' of the evaluation form was extremely helpful for students who were reluctant to give their friend a score lower than a 3 and those students who were super picky. Students had to validate their scores in the comment section by suggesting what could be fixed.

I did have to talk to some students about how they handled some of the mailboxes. They tended to use excessive force when testing whether or not the mailboxes would fall over. Next time I do this lesson I will model how to test for this criteria. 

Some students responded to the testers and rebutted their evaluation, showing they felt comfortable with their classmates to challenge their evaluation and to support their claim with evidence.
