Extra Credit: The Downfall of America?

Why? Extra credit, sitting innocently enough by itself, doesn't sound so sinister, right? I found that more often than not, extra credit was being requested by students who wanted to raise their grade. What a fantastic situation: eager students who were requesting to learn more? How could I go wrong!? Often, I found, the extra credit I assigned was for the student to investigate, learn or understand more knowledge, and it often was extension material. If I'm being totally honest with myself, more times than not, students were using Wikipedia to look up information that someone else had researched, wrote a few paragraphs, and hope that Mr. Guditus was feeling generous and hadn't forgotten his coffee that day (there was no rubric, of course).
After being totally honest (and vulnerable) with myself, I realized the purpose of extra credit was flawed: I was taking students who were struggling with mastery of a topic, and piled on what amounted to additional busy work, and raised their grade as a result. WHAT?! This couldn't be: I was a thoughtful teacher: how had I let myself get away with this? Teachers are human, and I let emotions drive my decisions, not thinking about the students. I had forgotten that kids don't always get to make the decisions in the classroom, and that as the teacher, it was my responsibility to determine mastery, and (here's the punchline) what to do when students do not master the material. I think it was ignorant bliss. I hadn't realized I had stumbled upon a big question: how do I handle students who struggle? And seemingly, I wasn't. Those who were motivated got a boost in their grade, but those who were embarrassed, unable or unwilling to approach me simply got diddly-squat. This is unacceptable.
Now, here I was facing a bigger issue: how do ensure that students are learning? It appeared that just giving additional research projects willy-nilly was not the solution. Not to mention, what about those high-achieving students who had demonstrated mastery? Extra credit may or may not have motivated them, but was it fair to only offer extra credit to struggling learners? Would they stop when their grade reached a 100%? Am I teaching them to be learners for the sake of learning? I had opened Pandora's Box. But I'm so glad I did. Because ultimately, extra credit isn't about ensuring learning, it's about superficiality: raising grades to make students, parents and teachers feel good about themselves, without actually demonstrating mastery of the concepts from class. Shouldn't a grade be a reflection of understanding of the curriculum? It simply must be so.
My next year of teaching, I confidently listed "No extra credit is offered in my classroom" in my classroom policies, as well as "assessments under 70 are required to be retaken." I expected the worst: posters, riots, protests. Nothing. After the first assessment, one reflection of student understanding of the material, I contacted students who had scored below a 70, letting them know they must have:
- Parent signature.
- After-school/before-school conference with me.
- Written reflection of why you got the grade you did, and what you will do differently to prepare for the next assessment.
- Personalized additional study work, due in one week (this looked differently, depending on the assessment and the preparation that was done or not done) to ensure missing concepts were covered
- Retake the test or quiz, following this cycle, until a 70 or better was achieved.

Teaching is hard work. As educators (and as an administrator), we must not allow ourselves to take the easy way out, but closely follow our students' mastery, and teach them that learning for learning's sake is important, and that understanding and success is not an option: it's mandatory, and the basis for ensuring that all our children learn.

One approach I use (as an English teacher) is to offer one "extra credit" per quarter, but with a twist. Students have to write an essay about an article that I provide, and the grade on this replaces the lowest grade on an equivalent assignment (sometimes a zero because they blew off that assignment). This gives students the reading and writing practice they need. And because it isn't added on, but just replaces a bad grade, it won't help a grade-grubber much (you know, the kid who wants to turn a B into an A after being satisfied with good work but not great work all quarter).
