Let me explain. There’s a math epidemic (remember Ebola 2014+). Students are bleeding out from the gashes of their misconceptions of mathematics. The lack of teaching conceptual understanding along with sacrificed opportunities to make mathematical connections is the double edged sword. This is an epidemic, and some teachers, school systems and educational leaders are treating it like it’s a tiny scratch, instead of the pervasive threat to mathematical achievement that it is.
Here’s a familiar scenario: A school’s test scores come back after the spring testing season (or mid-terms). The scores show little growth from the previous year in the area of mathematics, and any change is not in a positive direction. The knee-jerk reaction to the valid question, “What can we do to fix this?” is to look for programs and technology that will fix the problem. These are the same individuals who, way back in August, looked us all in the eye and, with the greatest of sincerity, reminded us that the single most important factor determining student success is the quality of the teacher. Not new programs. Instead of growing the quality of teachers, we get programs that:
- push speed over comprehension (imagine if we taught reading this way).
- define fluency based on digits rather than efficiency, flexibility, and accuracy.
- use technology to separate us from our students when we know that what we really need is to spend more time listening to them and creating an interactive classroom with technology as a support for this human interaction
- are essentially Band-Aids
I often hear the phrase “back to the basics” in times like these. I’ve heard parents, administrators, and even a few teachers say this. I think everyone would agree that “back to the basics” should mean that students become computationally fluent. The idea of going back to this implies that we were doing something right before. And we all know that’s not true. After all we have generations of adults who are not computationally fluent and/or have extreme math anxiety. And how did that happen?
Answer 1: Timed tests. My sixth grade teacher called them speed tests. We did them every day, right after lunch. (I was never in the top 10).
Answer 2: Algorithms memorized by students with no understanding, presented by teachers with little understanding other than from a teachers’ edition.
Answer 3: Little or no real problem solving. Naked computation all around. No wonder students were turned off by mathematics!
Answer 4: No interaction. Math is a social activity. If you talk to any engineer, designer, architect, mathematician, statistician, etc. They aren’t doing their work in an office silently sitting in rows. They’re constantly talking to one another about the mathematics they’re using. The idea that all of us are smarter than one of us makes so much sense in the real world and it should make sense in the classroom as well.
If we went back to teaching math like we did 20-30 years ago (I think that’s what some of these folks were implying when they said “back to the basics.” We’d still be in the same boat. Anyone ever watch How old is the shepherd?. That was popularized over 20 years ago and the results haven’t changed. Going back is not an option. Building fluency is.
So what do we need to do in math classrooms? I have a few ideas to stop the bleeding and these are certainly not original to me.
- Apply pressure to the wound. Give up on the ineffective treatment, not the patient. Apply pressure to stop the bleeding. Focus on tasks and activities that build number sense. Number Talks, Math Talks, Estimation 180, Visual Patterns any or all of these can be put in place at any level. And the best part is, students can easily be trained to begin to apply the pressure themselves. They have the power to stop the bleeding!
- Close the wound. This can only happen with stitches. And it takes time to get the hang of it. The wound has to be closed with the thread of understanding. We can’t understand for them, so the wound has to be closed with the help of the students. The students create this thread as we stitch and we can’t do it without them. How do they create this thread of understanding? We have to stop telling so much and instead “be less helpful.” If we tell students too much, the thread breaks.
- Treat any symptoms that may show up after the initial treatments above:
Students may begin to rely on rote procedures with no foundational understanding
Sometimes unintentionally caused by parents & other adults trying to help.
|Misconceptionitis||Identify the misconception(s) and re-build understandings using the CRA (Concrete Representational Abstract) model|
Students are finding unreasonable solutions to tasks & problems and they often seem unaware; clueless
This is often attributed to students just not thinking enough. Treatment should include a DAILY diet rich in estimation – prescribe www.estimation180.com
Students count (often on fingers when computing or rely on a calculator for the simplest of calculations and even then, they can get incorrect answers.
This is often diagnosed along with unreasonableness (see above). Its roots lie in naked computation and memorization of facts rather than allowing students to build strategies and practice those strategies until they become fluent. First, counting strategies are the lowest level strategies. Students need to build more efficient strategies by exercising with investigations of number relationships through number talks, math talks, and strategy building. Stop giving speed tests.
|Students have strategies for computation, but are not applying them in problem solving situations||No Solvia||
Students need a heavy dose of problem solving every day. This must involve students engaging in the Big 8 Standards for Mathematical Practice. Problem solving tasks every day. Hydrate often with student reasoning. Adopt the classroom mantra: “The answer isn’t good enough.”
Begin new concepts with a problem before any formal instruction on the topic. See what students can do before assuming what they can’t do.
