• Bass1: Instead of just asking me to "go read about JITT",
this exercise helped to guide my reading and get me
thinking about the applications of JITT in the classroom.

– This makes sense, but something is missing…
– This is a great response… how would we know how much

– This has a great beginning, but more could be added…
– This is correct, but the reasoning isn’

Tips
p and Pitfalls
• Explain methods and purpose on first day
• No need to review all responses before class;
sample for “useful
useful”” quotes, grade later
g , too,, not just
j
• Focus on students strengths,
misconceptions and other problems.
• Use answers from many students: not favorites.
• Do not “isolate
isolate”” WarmUps - scaffold lecture
• Must be routine. Do not start/stop during semester
• Upper level students can handle more
“exploratory
exploratory”” questions, connections to intro.
19
What makes a ggood WarmUp?
p
• king: A good "warmup
"warmup exercise" lets a student
motivate and think for the upcoming lecture on
that topic. It is like the "spark"spark-plug" in a car.
• JD: …One
One that connects directly to the main
goals, new notations, and possible
missconceptions in the upcoming material
• Tycho
Tycho:…
:… those that test the student's
understanding and those that stimulate class
discussion and are typically more open ended.
