effectively communicate throughout
the entire project and to complete
the app with an equal share of work
contributed.”
“I'll know I'm successful when I feel that we're
constantly emailing, iChatting, and talking in
school about our app and keep each other
updated on how we're doing and what we've
accomplished.”

80. • Many different formats

• Read through all of your Record of
Thinking entries, Moodle Logs, Conference

• Clarity, Specificity, Logic, Breadth, Depth

90. “Making an app like this on our own is really fun
because it can be frustrating, but we're
frustrated together and whenever we solve a
problem … we experience a great feeling of
success and happiness. In fact, there were a
couple of times, like … when we first got a dot
to follow your touch, when we both jumped up
and high-five'd each other as hard as we could
and just yelled in success. Each step is like a
terrible, horrible, twisted forest. But when you
finally work your way out and look back at what
you did, you can look at the path that you
hacked through your problem(s) with pride.”

Competition was minimized
AP Exam was marginalized
Achievement gap widened
