My Sociology 101 professor taught me something over ten years ago that has stuck with me ever since. I struggled in that class, and once again I raised my hand and expressed my confusion. "Kevin, you know the secret to academic success." Really? I was fighting for my B+ at the time. "You know what you don't know." Later I would learn that he was referring to meta cognition--thinking about thinking--knowing what you know and don't know.
Student C knows she does not know the correct answer and naturally wants to avoid exposure to her teacher and peers. She will not raise her hand. If we're lucky she will learn the correct answer from Student A, recognize that she has some studying to do and will prepare diligently for the exam. Another possibility is that she is discouraged, feels like she's just not good at English, and decides that Shakespeare is stupid. Either way, there is no mechanism for me to intervene.
At some point I did write, "He's hiding in the garage. I know the type. I was a hider as a kid." However later Ria Mengin who is an editor at The Salinas Californian posted on Facebook:
In my classes, Student D needs my attention. Not just because he's not prepared for the test, but more importantly, his mindset prevents him from recognizing that he's not prepared. I'd like to provide that attention before the test, not after. In a future post I will present a cool little piece of free technology that will help me accomplish this so we could all know what we don't know.
