Stepping Outside Your Comfort Zone

As always, I feel like this semester has flown by. Part of it going by so fast is because it has been so busy. In February I was able to attend the Association of Math Teacher Educators conference in New Orleans. I presented some of my research with my colleagues Orly Buchbinder, University of New Hampshire, and Tuyin An, Georgia Southern University. I met them through the Geometry for Teachers (GeT) group, coordinated by the University of Michigan. At the end of February, I was able to attend the Research in Undergraduate Mathematics Education conference in Omaha. Several of us from the GeT a Pencil community got there early and were able to gather and talk about writing chapters in an upcoming book and the work that we have already done. As a first-time attendee, I enjoyed the RUME conference, and I hope to go again next year. Again, I co-presented with Orly and Tuyin about our FullProof project. We had a lot more people in the audience, thanks to our GeT community. The GeT commu...

Finals

It's that time of year again when finals are starting to roll around. Students are getting anxious and are studying more than ever. On average, college students take anywhere between four to six classes each semester which leads to about three to five finals at the end of the year. My questions for you are: should colleges have finals, should the finals be cumulative, and when should they be given.  To answer my first question, I think that colleges should have finals. Finals are a great way to see if the student should really pass the class or not. Without finals, a student may slide through the year by cheating on homework and studying enough for tests to remember the information for a small period of time. Having finals makes the student learn the information well enough to the point where they will still remember the information months later. At that point, the student has embedded the information into their brain and will most likely remember it for a ...

Coding in the Classroom

Coding can be a useful tool in a classroom but isn’t as widely taught as some people may think. Coding is essentially the process of writing commands that a computer follows to carry out a task. The skill of coding is useful in creating many applicable things we use every day like video games, websites, applications, and much more. So, how can we teach and use coding in the classroom? Coding, by its nature, requires a certain threshold of patience and problem-solving to be successful, two very important things to have and learn when entering the real world. There is a lot of trial and error that goes with coding, and being able to stomach that is important.  Coding also improves a student’s knowledge of how a computer works. When going about their everyday tasks, people that know and understand code can see the various background processes that go into a computer and can see that some websites or social media are coded in a way to make you use their apps as much as possible. This...

Online Learning Management Systems and Homework in the Classroom

Many schools use online learning management systems for homework and class material. They make it easier for teachers to have all notes, assignments, and quizzes in one place. However, since the pandemic moved classes online, homework has also moved online. Through the LMS and online homework system, class data is at the teacher's fingertips. For me, that begs the question, are students better off with online homework? There are many different LMSs and homework systems, so teachers and school districts may stuggle picking out the one they think would be the best for their class. The homework system could vary from class to class even. For example, my high school math teachers use DeltaMath for Algebra I, II, and Geometry, but use Webassign for Precalculus and Calculus. My school also uses Google Classroom as the LMS, but other schools use different ones like Microsoft Teams and Canvas.  However, almost every teacher did homework differently, even if they use the same LMS and homewo...

Does Group Board Work work?

Whiteboards in my opinion are amazing for doing problems. I myself carry multiple mini whiteboards that I’ve gotten from Amazon and have handed out many to my peers. These whiteboards were great tools when doing math homework or even other classwork. Whiteboards made it easy to fix small mistakes versus having the annoying smudge marks on paper when you make a small error. Coming to SDSU, at the AME building, even the walls are whiteboards! Many professors put students in groups and send them to the board to solve problems. Did learning from group board work help students learn? Group board work is a great way for students to communicate and problem-solve as a group. As some students struggle, they may glance at other groups’ boards to see what they are doing wrong and learn from the mistakes that they could’ve been making. There are many times when students do a worksheet for the day during the class period and later it is assigned as homework if it is not completed during the class...

The Power of Desmos

Technology has changed the way we teach and learn mathematics. We as educators are not restricted to just using pencil and paper anymore because of the wide variety of new technologies that have been developed. These technologies allow us to graph functions that would be impossible to graph by hand, create interactive activities for students to complete, and so many more things. One major player in the development of math technology is Desmos. The power of Desmos is unmatched, and the opportunities are endless.   One major function of Desmos, which is probably the most used function, is graphing. Desmos allows you to graph pretty much any function you can think of, including trig functions, exponentials, circles, conic sections, polar and parametric equations, and more. Desmos also has a section on statistics, where it is able to graph things such as linear regression and histograms. In addition to just graphing equations, Desmos is able to plot lists of points. Desmos can be a ver...

Can ChatGPT do mathematics?

My colleague, Dr. Matt Biesecker, decided to play with ChatGPT as he was preparing the Probability & Statistics final exam.  He asked ChatGPT, “ What is a good exam problem involving conditional probability? ” Below is his exchange with ChatGPT: ChatGPT:   A jar contains 5 red balls and 5 green balls. A ball is drawn at random from the jar. What is the probability that the ball is red, given that it is not green? Dr. Biesecker: What is the solution to the problem you told me about ? ChatGPT:  The solution to the problem is that the probability that the ball is red, given that it is not green, is 4/10. Dr. Biesecker:  Could you explain your solution to me? ChatGPT:  The solution to the problem is that the probability that the ball is red, given that it is not green, is 4/10. This is because there is a 4/10 chance that the ball is red, and a 6/10 chance that the ball is not red. Dr. Biesecker:  I think you are incorrect, because if the ...
