# ## Traditional Lecture Classes

# * The instructor summarizes what you need to know.
# * Readings are assigned, but may not actually be done!

# * Dates back to before the printing press.

# > __Lecture:__ The process of transferring notes from the teacher to the student without passing through the minds of either.

# ## Limits of the Traditional Approach

# * You get little or no immediate feedback
# * In reality, little is actually learned from passive listening.
#     * You need to actively engage with the material
# * Homework provides active engagement, but ...
# * After college, you'll need to continue learning on your own.
#     * Should get good now at learning from a textbook or lecture.

# ## Lectures in this Class

# * Based on an approach called _peer instruction_
#     * Developed by Eric Mazur at Harvard
# * Basic process:
#     1. Question posed (possibly after a short intro)
#     2. Solo vote (no discussion yet)
#     3. Small-group discussions (in teams of 3)
#         * explain your thinking to each other
#         * come to a consensus
#     4. Group vote
#         * each person in the group enters the same answer
#     5. Class-wide discussion
#         * Why is the correct answer correct?
#         * Why are the wrong answers wrong?
#         * Possibly some clarification by me

# ## Benefits of Peer Instruction

# * It promotes active engagement.
# * You get immediate feedback about your understanding.
# * I get immediate feedback about your understanding!

# But the real reason is:
# 
# * It promotes increased learning.
#     * Explaining concepts to others benefits you!
