For the last 10-ish years, I have used Standards Based Grading in my classroom. What this looks like has evolved over time, but overall, the same basic principle was at work. My classes are broken down into overarching ideas that span the entire grading period. Those ideas are each marked separately and repeatedly. Students are able to see the ideas in which they perform strongly and which ideas they need work on. The targets I have written for my classes are ones that we circle back to over and over throughout the trimester. We don't stop talking about conservation of mass because we had a test over that unit. We come back to it and apply it to new situations and explain why it is such a big deal. I have tweaked and perfected over the years, and I love how this system lays out my curriculum and my classroom.
But I'm tired. I am still the only teacher in my 7-12 building that uses this type of system. I have gotten an impressive amount of push back from a lot of people. Interestingly, that has only come about in the last few years since I have been teaching chemistry and now physics. It comes mostly from parents of "A" students who don't want to understand the differences. And those are only the parents I hear from. I know my principal (bless him) acts as a firewall for me and I do not hear most of what is said.*
He does a good job of communicating the concerns with me. The biggest criticism has been that a grade at any point in time before the end of the semester does not reflect the student's understanding of the material. In other words, if a particular target is going to be reassessed and that grade might change down the line, then why should their grade be so low right now? Why can't little Susie just have an A all trimester if I think she will end up with one at the end.** This has been tweaked so that there is less variation in the grading than I had before, but grades are typically still lower than what most parents find acceptable.
My grading philosophy has not changed. I still believe that a student's grade in my class should only reflect what they know. I'm not bending on that point. I won't grade homework and I won't give participation grades. I hate how a percentage averages out so it's okay to not fully understand some topics. I have, however, given a bit on that one this year in a tweak I made to how scores factor into the final grade.
The irony*** here is that I have had so many students and parents place the blame for lower than desired scores on the system. This is not the reason. The reason is that I expect my kids to have a high level of understanding of the subject. But, of course, it is easier to put the blame on something they can't control. This argument is the main reason I am thinking about going back to a traditional system. Of course then I would just have to deal with all the complaining about the class being too difficult.
Today, my chemistry class had their first quiz of the trimester. So today or tomorrow, I am going to have to decide which grading road I am going to travel down. I know which one will make my life easier.
*This in itself is especially frustrating. Parents are always welcome to visit with me directly, but a few of the most outspoken won't and instead seem to want to apply pressure indirectly.
**Actual question from a parent...
***In other news, today in chemistry, we were discussing average atomic mass and how it was figured based on weighted averages. We do this by comparing it to weighted grades that some teachers use. Not a single one of my students knew how to figure their final grade using weighted averages. Some of them couldn't even explain a straight average. I just wanted to ask if you don't understand the traditional system, what difference does it make if I'm not using it???
