During classroom discussions, my room used to sound a lot like this:
Me: What do we know about these angles (points at
a set of vertical angles)
Students: -----
Me: What do these two angles share?
Student A: A point
Me: Great!
Where is that point located?
Student B: Where they cross
Me: What is that point called?
Students: ------
The "discussion"
would go on from there with me asking ever more information loaded questions
trying to get the students to the point that the angles were vertical and
therefore congruent. It seriously made
me doubt my teaching abilities. Until
the day that a light bulb went off in my head that is. I realized that their lack of ability to
answer my question had less to do with an understanding of the concepts and
more to do with the fact that they lacked the language to express themselves
mathematically. I sat down that evening
and made a list of all of the vocabulary that was new(er) to that unit. Terms that they might have heard in passing or
ones that I might have used, but not ones that they had ever really
practiced. I came up with almost
40. I was astonished so I went back
through the unit I was teaching and double-checked. Nope, no mistake, it really was almost
40. The next day I went into class and
gave them five of them to define as bellwork.
The majority were able to give me two.
At that point I felt like I was in an old space movie - you know: "Houston, we have a problem"...
As any good teacher does,
however, I took the problem as a challenge to be tackled, addressed and fixed
to benefit my students. Out of this
problem was born a simple solution - vocabulary assignments to launch each unit
and periodic vocabulary quizzes through each unit.

The vocabulary quizzes that
we do through the unit vary. Sometimes
they are matching with the definitions in one column and the terms in a
second. I also give them quizzes where
there are paragraphs to fill-in with words from a word bank. The hardest version, and the one that I tend
to save until towards the end of the year, are the ones where I just give them
the definition and they supply the word without being given a vocabulary list
or word bank. I find that as the year
goes on, their scores on the quizzes get better and better.
