Reflection Questions

How does Glen integrate kinesthetic experiences into his classroom?

Glen has students physically represent some of the key concepts explained in the lesson.  

  • Glen points out the differences between musical instruments and engineering instruments by having students act out playing a musical instrument. This helps them remember that the word can be used in two different ways. (:33- :45)
  • Glen has students act like fashion models in order to help them remember that the word “model” has different meanings. (:28- :31)
  • When explaining mass, volume, and density, Glen has students stand up and expand or contract their bodies to help them remember the concepts. 

What strategies does Glen use to help keep the vial testing process orderly and make sure students understand the results?

Glen assigns roles to students, testing each vial one at a time, and demonstrates how to record results after each test.

  • Glen assigns one person from each table to be the “tester” and another to be the “artist” who records all the results. (4:56-5:18)
  • Glen asks for predictions from the class before each vial is dropped into the tub of water.
  • Glen draws an image of the tub on the white board and uses magnetized pictures of each vial to indicate its position in the tub. (3:47-4:10)
