Can one lurk in a face-to-face learning environment?

I’m thinking about a particular student I have this whom I have to prod to speak up about anything (the equivalent of publishing in our CCSS class, right?) but then when I read her writing it’s beautiful and I can point to specific things she had done that I know she has taken away from conversations we’ve had during class.

So, I guess when I look at her writing, that’s when she’s no longer lurking.

But I’m still curious about my question: Can one lurk in a face-to-face learning environment?
