As the third quarter comes to an end for many schools, I wanted to take the time to share why I, as an English teacher, spent time showing my students a very specific math skill: calculating GPA. I did this when I was teaching 9^{th} & 10^{th} grade English, although I also did a modified version of it this year with my 7^{th} grade math students. However, middle school transcripts aren’t as focused on GPA – at least not in my district – so it depends on your circumstances whether or not you’d want to do this as a middle school teacher.

As a non-math content area teacher, I had to really weigh the pros and cons of taking an entire class period to go over a math skill. All our curriculums are over-packed. We don’t have days to “waste.” Was I ready to give up a day of curriculum to teach a skill that wasn’t directly related to my own curriculum and standards? Well, honestly, the first time I did this, I hadn’t intended to take an entire class period. My goal was to put up the grade calculation chart to show my students how their 3 grades (quarter 3, quarter 4, and final exam) worked together to get their final semester grade. That was only supposed to take maybe 10-15 minutes. I knew I could spare that. I knew I had to. But, as the conversation took a turn to GPA and how that is calculated and how “bad” one grade can be for a GPA, it didn’t take long to figure out that my students had zero idea how to calculate their own GPA.

This was a serious problem since I worked with freshman. Those of you who work with underclassmen are well aware of the thought process these students have. So many of them don’t think their grades matter. They don’t realize the damage a bad grade in 9^{th} or 10^{th} grade can do to a GPA. They don’t understand that they will spend the rest of their high school career fighting to repair a GPA that has been devastated by a “C” or, heaven forbid, a “D.” Let’s not even talk about the “F”s. When I tried to quickly explain the GPA calculations, my students immediately took an interest. They demanded I slow down so they could take notes. Seriously, I had students who rarely paid any attention to a single word I said and when I started talking about their GPA they were like, “Woah, woah, woah, Miss! Slow down!” They cared about this. What shocked me was not so much that my students didn’t know how a GPA was calculated – after all, it would be unlikely that they would have learned that in middle school, given the emphasis (or lack thereof) placed on GPAs in middle school – it was that their *math* teachers hadn’t taught them this when they started high school.

I realize now that I shouldn’t have been surprised. As teachers, we assume a heck of a lot of knowledge for our students. We assume they just know things because we know them. We forget how we learned. It doesn’t occur to us to teach things we ourselves know and/or expect our students to know. And I’m not talking about curriculum concepts, I’m talking about this type of stuff: GPA calculation, test-taking techniques , how to bubble a freaking Scantron sheet correctly. So I taught them how to calculate their GPA. The first time, I had to fly by the seat of my pants. I had to guess how much our district weighted honors and AP classes. I let them know that my assumptions could be wrong and they should do their own research to figure out how their specific class load would work out. But the next time, I was prepared. I did my research and found the district’s weighting system and how GPA was calculated. I budgeted a full class period for it, and it paid off. And my students were enthralled and thankful. It honestly changed a lot of perspectives. I know a lot of my students changed their attitudes towards their effort in classes because of this lesson. I know because they told me themselves. I saw some students improve their efforts in my class, and I know other teachers saw improvements in theirs. They might not have known why, but the improvements were there.

You might think that the kids who cared were only the college-bound ones. The kids who knew they had no shot might not care about anything except graduating. Why bother with trying to get “A”s and “B”s when all you need is a 2.0 to graduate? Or maybe they were planning to drop out; why should they care about a GPA as a freshman when they knew in just 2 years they’d be out of school anyway? Well, what I’ve noticed is that students who think they can’t control something often become apathetic towards it. If a student thinks a GPA is some sort of magical number over which they have no control and no influence, they have no reason to devote any time or energy towards caring about it. But, if you show a student – any student – that THEY control this GPA, it changes a lot. Really, this is true about many things for students. They don’t have a lot of control over things. Give them a little bit of control and it empowers them. It engages them. And that’s what this lesson did for my students – all of them, even the low-performing, unmotivated ones. It gave them the knowledge that THEY controlled their GPA. And that changed everything.
