We frequently collect informal data about which students are “getting it,” so we can adjust our teaching accordingly.

Maya Gomez
The second part of Ms. Gomez’s lesson (where students hold up the sentence strips) demonstrates the teaching technique we call Data collection, because it allows Ms. Gomez to know instantly which students are “getting it” and which students need more help.She tells them when they make a mistake and asks them to correct it themselves—so students are able to adjust their efforts on the spot and make more rapid improvements.
