knowing the wrong answers

we were talking about assessment literacy last week. and i chanced upon this article via fb feed “Why Teachers Need To Know The Wrong Answers“. to be able to assess students’ learning and facilitate improvement, teachers need to know all the answers (and their corresponding Whys).

some lines that caught my eyes include:
“‘Students are full of all kinds of knowledge, and they have explanations for everything.’ From birth, human beings are working hard to figure out the world around us.”

– and how often teachers are responsible for ‘killing’ this curiosity?

“‘cognitive science tells us that if you don’t understand the flaws in students’ reasoning, you’re not going to be able to dislodge their misconceptions and replace them with the correct concepts.'”

– very absolute terms here, very ‘science’ — right vs. wrong. what do we have that are clear cut right and wrong in CL? and how often are we able to tell why one is right and the other is wrong? how many CL teachers have acquired the necessary linguistics knowledge, or the awareness/ability to learn about them on-the-fly/on-the-job/on-demand?

“‘Teachers who find their kids’ ideas fascinating are just better teachers than teachers who find the subject matter fascinating,'”

– i am not sure how many teachers around me are actually FASCINATED by their students’ ideas. i suspect more ‘irritated’ & ‘frustrated’ than anything else.

“‘The next step is to give students exposure to the information and experience that will enable them to reason their way to the right answer.'”

– and how often teachers just tell students the “right” answers outright in the face? in the name of efficiency of learning?
