Education can be thought of as ratios:
Time on Task:Time for Planning
Use:Cost
Learning Gained:Time Invested
Passive Learning:Active Learning
"Sage on Stage": Coach
New Ideas: Old Ideas (is it the ratio that matters here or the quality of the ideas and their effect)
Learning that can be quantified: Learning that can't be quantified
Project Base Learning: Skills
Teachers: Leaders
Teachers: Students
Classrooms: Students
Time With Students: Time Not With Students
What ratios would you add to this list?
