How do you prepare for big lectures? geek-new

s.mtv.com

Suggestions: 1.  Figure out your main points

For lecture and for each slide 2. Prepare your visuals (draft) 3.  Practice your unfinished talk ALOUD 4. Write out sentences that need to be precise 5. Focus on your slide transitions

Better than “And this slide shows!” 6. Revise your slides 7.  Print out your notes 8.  Keep track of time 9.  Calm your nerves beforehand 10.  Don’t install new software right beforehand 11. PRACTICE

EXPRESSIVENESS is the most basic and most direct way to keep students’ interest

ZC)):'(#("I"'+)+,&((",-)“Interactive lectures: classes in which the instructor breaks the lecture at least once per class to have students participate in an activity that lets them work directly with the material”

1. Engagement triggers: 1. Interpreting graphs 2. Making Calculations 3. Demonstration/ making predictions 4. Brainstorming 5. Reading to solve a problem 6. Physical prop 7. Evocative visual/ picture 8. Cartoons 9 . News clips 10. Clips from movies of tv shows

2. Incorporate into an activity 1. Think-Pair-Share 2. Small group discussion 3. iClicker 4. Audience participation

some starter fill in the blanks:

A. Lisa is half right. They both drain counterclockwise

B. Lisa is half right. They both drain clockwise C. Lisa has it backwards. It should drain

clockwise in Northern Hemisphere, counterclockwise in Southern Hemisphere

D. Bart is right. The Coriolis effect is negligible on the scale of toilets and sinks.

E. Lisa is right (as usual).

Lisa Simpson says the water drains counterclockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere.

B. Using Blackboard/course website/Facebook - make TA in charge?

C. Dealing with academic dishonesty - use plagiarism software - have students do academic honesty assignment

D. Dealing with legitimate excuses - expect them and have a plan

E. Classroom technology

Teaching a class with over 100 students is a management challenge. You will have students who have conflicting school activities, personal crises, learning disabilities, health issues, and academic integrity issues.
