I saw this when I witnessed a TPRS lesson for the very first time in Michele Whaley‘s class last spring. It’s very quick, easy, and informative.
It is important to note that this is a formative assessment, so it should not be entered in your gradebook. This is something that will give you a quick snapshot of how well your students have understood some chunk of spoken Spanish. It is meant to be given while students are in the process of learning the material, not after they are already expected to know it. Also, it is much too easy for students to cheat (open their eyes, listen for the sound of their neighbor’s arm moving) to count this as a grade. Anyway, like I said, it’s still very helpful for you to know if you need to keep circling or if you can move on.
All you do is think of several true/false statements or yes/no questions. Students sit with their heads down and eyes closed. If the answer is “true” or “yes”, students raise their hands. If the answer is “false” or “no”, students leave their hands down. You just record who misses each question. Ask three to five questions, and you will quickly see which students are well on their way to acquiring the material, and which ones struggle without the textual support provided by the words on the board.
