Last week I had the students in my class do some work in the lab that formed the basis for the next two labs. When I looked at the results they got I realized that I was going to have to re-do much of the final step so that the actually would have something to work with this week.
However, I needed some details from each group in order to help me create the right conditions for the re-do. I emailed the whole class to send me the information I needed and their partner's name so I wasn't doubling up on information unnecessarily. Only 20% of them got back to me, which is not entirely surprising, but what was shocking is that only half of those who responded knew their lab partner's name.
Last week was the ninth lab of the semester. NINTH. That means I have several students who have worked with a classmate for hours on end of this semester and have never learned their name. And I only had 20% respond to me! WTF? Maybe I'm just getting old enough where I like to the names of the people I work with, I don't know. Now get offa my lawn.
