Lay It On the Line, Lay It On the Line

Bitmoji ImageOne of the "revelations" I had over the past few years that has helped me change my instruction was that having someone else waste your time sucks. I enjoy having my time wasted as much as the next person. Which is to say, I do not enjoy having my time wasted at all. It is one of the things that irritates me the most.

When I realized that students often feel that way in school, I knew I had to be different. I didn't want to lecture any more than necessary. And when I did, I wanted to err on the side of talking too little. If a student can learn something without me, I want them to do so. If I could assign 15 problems instead of 30, I'd assign 15.

I was reminded again recently of what it feels like to have your time wasted by someone else. I am in a graduate class and one of the requirements for the class is that we post solutions to homework problems on a discussion board and others respond to them. You can't see the solutions others post until after you post your own, so I like to complete as much of the assignment as I can up front and then decide which solutions to upload. A recent post by one of my classmates offered what was a correct solution to a proof. It was well written, neatly typed, and only a page long.
Bitmoji ImageAnd that's what irritated me so much. I read the solution and realized that it was way, way too long. My time had been wasted. The problem did not require such a thorough treatment. Which sounds strange to say, but it didn't. It really didn't. At least not for the audience that would be reading it. And that was when I understood what many students go through on a daily basis.

I have several students who read this blog, and if we are being honest with each other, I think they would admit that when someone over-responds to a question, it may be for several different reasons;

  1. the student has no idea what they are talking about and is hoping that by saying a lot of things they may say something coherent and get some credit,
  2. the student knows what they are talking about but doesn't understand how much of it is actually required to respond appropriately to the question being asked,
  3. the student knows what they are talking about and wants to impress the people who will read their response.
There's no way it was #1. 

Which leaves either #2 or #3. And I really hope it wasn't #3. At least if it's #2, then the extra time I spent reading the unnecessarily long solution wasn't taken from me deliberately.

As teachers, the question, "how much time do I really need to talk about this in class?" is a question that may seem inconsequential most of the time. I assure you that it is not. Being off by a little may not cause many issues. But being off by a lot can be a disaster. If we're not at least trying to answer the question, being off by a little just means we're lucky. Most of the time, our students won't be.

Better Late Than Never

I knew when I was in the 7 th grade that I wanted to be a Mathematics teacher. I knew I would need to go to college in order to make that happen. I knew I wanted to understand what it was I was going to teach so I would need to pay attention in class and do my homework. And it worked. I am a high school Mathematics teacher. Success! To be totally honest, I don't recall doing that much homework in high school. There are only a couple of instances that I can recall doing homework outside of the school day; studying for a Spanish exam with my brother, and trying to read " Beowulf " in the dimmed lights of the auditorium during play rehearsal. The other stuff must have gotten done. I did graduate. I just have no recollection of doing it. But I'll admit it, I'm not a stickler for due dates. I never had difficulty meeting them, but that was only because of the threat of getting a 0% on something and I wanted good grades. If I could turn in assignments late wi...

Good Morning Blog

This year I have made it a priority to stand outside my classroom door and personally greet each of my students with a "Good morning, Hope" or a "Good afternoon, Nick" as they walk in. The greeting helps each student know that they are welcome in my classroom and that I will do my best to provide them with a safe learning environment. A few weeks after starting this, I started to think about how often I was uttering the words "Good morning" or "Good afternoon" in a given day. It was dozens. And then I started thinking about how many times I would say it over the course of a year. Thousands . Potentially up to 10,000 times in a single academic year. That's a lot. I can't imagine that it is a bad thing for students to hear their teachers personally greet them almost 200 times per year. I also can't imagine that it is a bad thing for students to hear their teachers simply say the word "good" that many times. It just s...

Teaching Math In The 21st Century

I often get the sense that much of what people have come to understand about teaching and learning Mathematics is based on a decades old mentality that students will need to be able to do mathematical calculations with computer-like speed and precision once they enter the workforce. And in order to meet this need, mathematics instruction should look like drilling procedures over and over again so that students become proficient and ready to join the workforce. Here's the problem with that approach; it sounds an awful lot like the goal is to program students to behave just like little math computers. Which shouldn't come as a big surprise. Decades ago, people were already being told about the wonderful world that access to computers would usher in...once they became more readily available, that is. In the meantime, we'll need employees to function in much the same way. That sounds a bit dehumanizing. But here we are, 2018, and computers are everywhere . I'm writing...
