Reflection Questions

What techniques does Karissa use to help her English Learner students?

Many of Karissa’s students are English Learners and need extra guidance when it comes to vocabulary, understanding, and new concepts. Karissa brings the whole class into the discussion to keep them engaged.

  • Karissa asks the class what challenging words like “observe” and “durability” mean so that all of her students can learn or recall the definitions. (0:22, 5:35)
  • Karissa challenges her students to answer questions in complete sentences, modeling good speaking habits for others. (1:02, 1:10)
  • Karissa uses a visual aid (a Venn Diagram) to compare the differences and similarities between two materials. (1:12)
  • By using hand gestures, Karissa is able to convey ideas about properties more easily to her class. (3:06 – 3:27)

Where does Karissa use real world examples to help her students relate to their studies of properties?

Karissa uses learning opportunities to tie her student’s lives to their classroom work.

  • Karissa has one student compare the material she’s investigating to the sweater she’s wearing because they have similar properties. (2:40–2:55)
  • Kate shares in her interview that she asked her students to question why people use cloth towels instead of paper towels to dry themselves after a bath. (7:20–7:36)
