In my geometry class, I have been using Desmos Activity builder to teach finding points of concurrency algebraically. In order to assess my students on this unit, I decided to create a Desmos Activity. I also created a packet that had the same questions that were on my Desmos Activity for students to use to show their work. I like using Desmos because it allowed my students to check their answers easily by entering thier equations or coordinates. I can ask questions that don’t involve graphing, and it easily organizes students answers. It also made grading SUPER EASY.
When grading with Desmos you can either grade one student at a time by clicking on their name OR you can grade one question at a time. I decided to grade one question at a time. Because each students answers showed up at once for each problem I could quickly see which students answered incorrectly. You can also overlay all of the graphs to check students anwers quickly. If no students answered incorrectly I can see that immedietly.
In order to grade most efficiently, I created a grading grid (I usually use this to record homwork) with every student in the class’ name. Instead of putting the date at the top like I usually do, I put the Desmos slide number, the packet question number, and the amount of points each question was worth. I used this grading grid to grade this assessment. If student got the question correct I put a check in the box, if the student made a small mistake (and I could tell what they did from the answer) I would put minus the amount of points they’d lose for that question in the box. If I couldn’t figure out their mistake from their answer then I would write “check” in the box. When I finished grading all of the questions I would go through each students test. I ONLY looked at the problems where I wrote “check”. I use erasable pens when grading, so after I checked their work I could go back and change the grade in the box easily.
This was an extremely long assessment and took NO time to grade. Using Desmos for a quick quiz would be even easier! This was my first time using desmos for an assessment, but I’m definetly going to use it again!
