## Reflection: Lesson Planning Questions, Hypotheses, Variables & Controls...Oh My! - Section 1: Hook

The difference between teaching students what I think they need to know and understanding what they already know before I teach a lesson is one of the reasons that I like to use probes in my practice. Probes allow me to pinpoint areas of need and differentiate instruction, by uncovering what the students think they know and where the weaknesses might lie.

In this particular case, the students were able to identify the testable question, but as I quickly glanced through them as they turned them in, it was evident that students didn't necessarily know how to express why. This led me to spend more time during the presentation ensuring that they had questions to use to determine the "testability" of a question.

Probes can be used any time to inform your practice. They are powerful indicators of understanding, and can provide a road map for instruction. They can also help students deepen their understanding since they will almost always ask the student to provide reasons for their answers and in doing so, cement the concept being taught.
