Assessment mistake

Last week I taught my kindergarten class a science unit on force and motion. It wasn't a unit I created, but one that an intern in the other kindergarten created last year and the teachers liked, so I offered to teach it this year. On the third day we did a hands-on experiment where the students each got a chance to push little wooden cars through four different buckets, each containing a different substance: wet sand, dry sand, water, and air. At the end of the lesson I gave them an assessment showing the four items and told them to X the one that took the most force and circle the one that took the least force. I was going to give them clipboards and spread them around the room, but we ran out of time so I just had them sit at their seats. I repeated the simple (or so I thought) two-step instructions several times and even looked around the room for a quick place to write them down, but nothing was convenient so I just repeated them again.

The first two students handed in correct sheets, then a third student handed in a sheet with three circles and one X. Two more marks than needed and completely invalidating the assessment. I grabbed my one remaining blank copy and started to re-explain the directions. Before I got far though, other students started handing in their papers and I noticed every kid hand marked all four items with Xs or circles. All of them did it! I sighed, shook my head, and just started collecting them.

When I showed my mentor teacher she just laughed. She said, "I knew, as soon as you gave two step directions, things would not go well!" She had chosen, wisely, to let me learn that lesson all on my own. We both had a good laugh.

The next morning I made more copies of the assessment and pulled the kids aside one by one, telling them I had given them incorrect directions and asking them to redo the task. Many of them found it amusing that the teacher had made a mistake.

For the final assessment at the end of the unit I was careful to take them through the directions one step at a time. "First circle all the things you can push," pause, pause, pause, "Next put an X through the things that are moving," etc. My final assessments came out much better! :)
