These ideas cannot be "discovered" by young learners through any form of working with data or unguided observation...rather these ideas need to be introduced by you." (p156)

"Students need help imagining these unobservables because they refer to structures of processes that are inaccessible...too small to see, or too conceptual" (p156)

"interactive direct instruction is after you've given students a brief exposure to materials or data and let them puzzle a bit with well-designed questions."

Atomic structure is a concept that students cannot directly experience.

The activity was scaffolded to allow for smaller chunks of direct instruction and more time for students to discuss and make meaning for themselves.

Students created a template in which to record their observations and their wonderings. After each observation students were asked to share and discuss with table teams.

Eventually, I guided students to two overall questions...
  • What causes the light to be different colors for different elements?
  • What is happening to the atoms to produce light?

These allowed us to discuss Bohr's Theory with a purpose.

The demos and time for students to think and make connections allowed students to be open to the concept of Bohr's Atomic Structure. ]]> 2022-04-16 00:59:50 UTC https://padlet.com/kristi_deaver1/81y1nl9eva49410t/wish/2145249730 Model--Teacher Example kristi_deaver1 https://padlet.com/kristi_deaver1/81y1nl9eva49410t/wish/2149263824 2022-04-19 20:54:10 UTC https://padlet.com/kristi_deaver1/81y1nl9eva49410t/wish/2149263824
