What I learned this semester (Spring 2018)


Every spring when I teach Math 371, I learn something new.  Here are the things that I learned this semester:
  • Our math pre-service teachers are not fans of the TI-Nspire. If they had to use a TI calculator in their classroom, they would prefer an 84 or 84-plus.  We discussed at length that both Desmos and Geogebra are easier to use—and the only reason to use a calculator in our math classroom is to help students prepare for the ACT or SAT.  Here is a link to the ACT calculator policy and here is the SAT calculator policy.
  • We tried a new math and science app that interacts with Google docs, Equatio. This app allows you to type equations into Google docs using handwriting, speech, LaTex, and a regular equation editor.  We loved that part of it. I also tried the Equatio Mathspace and created an assignment for the students.  It turned out well, but we couldn’t figure out how to scroll down in the space so students couldn’t do the last problem. I will have to investigate that issue. Equatio is free to all K-12 teachers!
  • The students had no desire to learn or work with a programming language in this course.  I decided to incentivize it by purchasing a Sphero BB-8 robot.  It was cute, but we found it hard to control movements—there is an iPad app that allows you to draw where it will go and there is another app that allows block programming.  With both of them, it seemed hard to control. We might need to experiment more with the block programming.
  • At the state science and math teachers conference, Gail Jacobsma from Arlington, presented on her paperless classroom using OneNote. So we decided that we needed to look at that as an option for them to use in their classroom. This was easy for us to look at since we all have Office365 accounts.  I created a Class Notebook for the class, and then made an assignment for them. They said that they liked it, except they wanted a computer with a stylus (none of them have that).  I have a feeling that they might use this in their classrooms.
  • I was able to create a class in Google Classroom this year so we used that a bit.  I didn’t use it all the time, but I did use it to create an assignment in Google forms and Equatio and post these as announcements.  I feel like it is super easy to use and they will seriously consider it if their school uses gmail.
  • The students explored three learning management systems: Canvas, Moodle, and Schoology. They overwhelming felt like Canvas as the best from both the teacher and student perspective. I am not sure if many districts are using it, but it gives them another option.
  • One software that we didn’t get to, but I want to bring up is Planboard.  It is a free lesson planning software (you must use Chrome) that Katie Murtha introduced to us last year. Katie is using it during her student teaching and loves it.  You can upload your own lesson plan template and use it for all of your lesson plans.  It also allows you to check off standards as you teach so you know which ones you have covered.

It was another great semester of Math 371—I only had 6 students so next year will be an adjustment as I am anticipating about 15 students.  I think this may make some of my assignments more challenging, but we will figure it out.

Difficulties in Learning Are Okay and Often Beneficial



            There is a harmful perception among students that when a solution isn’t apparent or discernible in a quick time frame, that it is due to a lack of intelligence. This is an ideology that I am familiar with. Often a problem is presented and the smartest kid in the class shouts out the answer. The teacher then acknowledges the response without asking the other students or gauging for general understanding before moving on, and this can be discouraging to some. This encourages the mentality that, “if I am smart a solution will come easily”, which is absolutely not the case. As educators we need to explain to students that success doesn’t always come easily, rather it is often a difficult and tedious process. We need to teach the mentality that not all intellectual abilities are hardwired, and that learning takes effort to be meaningful and successful.

            Some teachers want their students to learn their material as quickly and easily as possible. These teachers will sometimes unknowingly take shortcuts in their classroom to help students learn faster with the false insight that because the learning is “easier” that it is better. This can include allowing students to use calculators for problems they should be doing mentally, giving multiplication tables simply for the sake of computational speed, or giving students a mnemonic to remember a topic before learning enough about that topic.  Somewhat recently, through studies and literature it has been revealed that creating desirable difficulties in the classroom leads to more effective learning. What desirable difficulties means, is that a teacher may incorporate things such as frequent quizzes that may have a couple of problems that haven’t been covered recently, or having students solve an answer before the solution is posed to them, as well as interleaving topics and problems so that students are frequently shifting gears. These strategies may seem counter productive because they aren’t as quick as having a student memorize an acronym, but when the learning is modeled in this way it is more meaningful and is also better for memory retention. Incorporating these learning difficulties into a classroom will help to transform the typical mindset from “intelligence being hardwired” to “learning takes effort”.

            It is important to explain to students that just because something is difficult, (specifically learning) that it isn’t meaningless. Students need to gain the mindset that success derives from hard work, and difficult learning often can be beneficial if incorporated successfully. This is something we need to instill as teachers, rather than providing “easy” learning strategies because it allows students to move more quickly through material.

Calculators: a useful tool or a crutch?

            One of the never ending in debates in the classroom of modern mathematics is where to draw the line with the use of calculators. First, what is the purpose of calculators in the classroom? Calculators are problem solving tools, generally used on equations that have obscure numbers or difficult trigonometric functions. But many times a calculator is used to find the answer as fast as possible, even if it is fairly simple product of two integers. Once a student becomes dependent on the calculator, mental math becomes hard for them because the calculator has been doing it for them.
Another concern is when students have a very powerful calculator that can do all the math for them, such as solving equations, taking derivatives, evaluating integrals, etc. Having a calculator like this can inhibit the learning of a student because they use it for all their homework and never take the time to do the mathematics by hand. Then when they take the test, they can’t demonstrate that they have learned the material.  If the student was allowed to use the calculator on a test as well, then that student could very well pass the class without truly knowing the material.
            Then when should we use calculators? A student could get through almost all of elementary math and middle school math without needing a calculator. They may need a graphing calculator in high school. However, there are many free online graphing calculators, such as Desmos and Geogebra, that are much more user-friendly than any Texas Instrument calculator. To use my experience as an example, I had a TI-89 in high school and used it for everything.  Once I got to college, all of the courses in the calculus sequence were done without a calculator. It was a huge adjustment for me because I realized how much I did not retain and that my calculator was actually a crutch to my learning. Now I am very thankful that the university teaches calculus this way because I am now more efficient with mental math.
      In conclusion I would say a student can go through almost all of elementary, middle, and high school without using a calculator. So why are they still around?  Several standardized tests, such as the ACT and SAT allow students to use them. In my opinion, education is slowly moving away from the reliance on calculators with the growth of free tools such as Desmos and Geogebra. So, is there such a thing as too much calculator? I would say, the moment you reach for it instead of first giving yourself a chance to think about the problem, it might be a crutch to you. Then it is inhibiting your learning rather than enhancing it.

Being Open to New Things in Your Classroom

            When I first declared a mathematics education major, I thought that I had every part of how I wanted my classroom to function figured out. I had the same mathematics teacher from 8th grade up until I graduated high school. I liked her style of teaching, so I thought I would be fine just copying her style of teaching. However, we never used any technology in her classroom. As you can imagine, when I first started working with technology in my Geometry for teachers’ class, and now my technology for math educators class, I was out of my element. I never knew that there were so many applets and programs that could help my future students with their mathematics.
            I have pretty much completely changed my teaching philosophy from when I first declared being a mathematics education major. It has been pretty hard for me to have the mindset that I need to incorporate technology in my classroom. I have had to spend a lot of time learning how to use the technology I have found in order for it to be useful in my future classroom. I continue to learn about new “tools”, websites, and apps that I would like to introduce to my future students.

            If today’s educators are not willing to be open to new things in their classroom, specifically regarding technology, they are not doing their students much good. Technology seems to be taking over. Anywhere you look, there is technology. So, instead of shying away from using technology in the classroom because you aren’t comfortable with it, teachers should be willing to learn about all of the different types of technology that they could incorporate into their classrooms. When I say this, I do not mean that I feel a teacher should use technology as their only source of teaching. The technology must be useful in order for it to make a difference in your students’ education.
