The Grand Rapids Community College Mathematics Department is pleased to announce that it will host its next Mathematics Seminar on Thursday, February 21, 11 a.m. – 12 p.m. in 103 Cook.

Our speaker is GRCC faculty member Brian Hadley.  For the title and abstract of his talk, please see below.

The realm of mathematical forecasting is vast but fundamentally based on common sense ideas: Examine historical trends, assume that whatever was responsible for creating the past will continue to operate beyond the present, then use mathematical and/or statistical techniques to predict the future.  Brian will discuss how this relates to classroom resource management.  As is the case with all of our seminars, everyone is welcome!

Refreshments will be served at 10:45 a.m.

Mathematical Forecasting and Classroom Resources

Forecasting student attendance in class has allowed for a reduction of wasted paper.

Each semester I print quizzes, test, and worksheets for class use. Unfortunately, some of this paper is wasted primarily due to absent students. As a solution to this problem, I began forecasting student attendance, greatly reducing the amount of wasted printing.

Forecasting is a mathematical model that allows for a prediction of future trends. We will examine various forecasting methods that can provide reliable guidelines to classroom attendance trends and result in the reduction of paper waste.

 

 

Raider Salute to Jeannie Dauber

This Raider Salute comes from student Megan Nordbeck:

I have to take time to recognize a past GRCC professor of mine — Jeannie Kuhn Dauber. She was my math 098 teacher during my first year at GRCC in 2017. As you can imagine, I was struggling with self esteem. I didn’t know whether or not I was capable of succeeding in college. Especially, all the time I took off after high school (graduated in 2008).

Jeannie is a tough teacher, but she really cares about all of her students. I had homework almost every night along with her many colorful mock tests. I did everything that Jeannie recommended and I passed her class with a 98.2 %.

Now, with this current semester I feel incredibly confident and some of that I owe to Jeannie Dauber. I currently hold a 3.6 GPA and have made the Dean’s List twice. Apart from the accolades, Jeannie and I are still friends. Once in awhile we’ll meet for lunch and what not.

Jeannie has continued to share with me about her ongoing efforts with her students. I wanted to showcase Jeannie’s dedication and how she handled things during the polar vortex. The polar vortex has been challenging for some students this semester. Specifically, when it comes to learning compiled material after missing 5 classes due to the bad weather.

Jeannie Dauber cares enough about her students to make lecture videos for Blackboard, meeting extra with her students so that they are caught up, and sending notifications about extra review time. Last Monday, classes were delayed until 11 am. Jeannie Dauber held an hour review session for her early morning class. The students who did not respond back to her notification received a phone call from her. All but one of her students showed up.

Jeannie is a prime example of an educator. I can’t imagine what my first year at GRCC would have been like without her. Thank you for all that you do Jeannie Dauber!!!

GRCC Mathematics Seminar TODAY in Cook 213

The Grand Rapids Community College Mathematics Department is hosting its November Mathematics Seminar TODAY, November 13, from 2:30-3:30 p.m. in 213 Cook.

This month’s seminar will be lead by former GRCC student Katrina Teunis. Ms. Teunis will discuss her research on mathematical patterns in the folding of RNA.

Recent research in mathematical biology includes areas such as genomics, biochemistry and cell biology, heart physiology, kidney function, and protein folding.  Everyone is welcome!

Refreshments will be served at 2:15 p.m.

 

The Math Behind the Foldability of RNA

“This summer I was given funding to do some undergraduate math research on the mathematical patterns in how RNA folds. RNA, much like DNA, is made up of four building blocks called nucleotides: Adenine, Guanine, Cytosine, and Uracil. These nucleotides form a string that likes to fold in on itself and bond together – Adenine with Uracil and Guanine with Cytosine. So, the order and number of nucleotides present will determine how many ways the string of RNA can fold. By assigning these properties to letters, we can study this in a general context. Doing this I was able to find several new ways of determining how many times a string will fold as well as how to build a string with a specific number of foldings. I was also able to find or strengthen connections between RNA and other areas of mathematics. In this talk, I will walk through how RNA folds, what I found in my research, and how RNA connects to other areas of mathematics. This research was funded by the Modified Student Summer Scholars Program from the Office of Undergraduate Research at Grand Valley State University.”

TODAY: Mathematics Seminar on Islamic design in Cook 102

The Grand Rapids Community College Mathematics Department is pleased to announce that it will host its next Mathematics Seminar TODAY, October 30, 3-4 p.m. in 102 Cook.

Our speaker is Rebin Muhammad from Ohio University, presenting on the mathematical symmetries in traditional Islamic designs. The variety of symmetries found in Islamic geometric patterns contributes to beautiful works of art and a wealth of opportunities for interesting mathematical explorations.  Join us for a presentation that will appeal to a general audience – all are welcome!

Refreshments will be served at 2:45 p.m.

 

Symmetries in the Alhambra

An Islamic geometric pattern is a two-dimensional wallpaper that is created by only using a compass and ruler. The history of Islamic geometric patterns dates back to the 8th century and can been seen in most Islamic countries, where it is used in decorating the walls of buildings and mosques. We will explore some of these patterns that are located in Alhambra (and other places) and see why they are mathematically interesting.

Two Students Awarded with the GRCC Faculty and Staff Centennial Scholarship

The GRCC Faculty and Staff Centennial Scholarship was created by the employees of the college in honor of GRCC’s 100th year celebration. Currently, two awards are given each year: one to an incoming student and the other to a returning student that has earned at least 12 credits at GRCC. These scholarships are awarded based on scholastic achievement as well as extracurricular involvement and community service. Applicants are also asked to submit a short essay explaining why they feel they deserve the scholarship. The recipients are then selected by a cross-college committee made up of representatives from each of the various employee groups (Faculty, Meet & Confer, CEBA, APSS, and Campus Police).

We are pleased to announce and congratulate the 2018-19 scholarship recipients for the GRCC Faculty and Staff Centennial Scholarship: Carley Hume and Rodney Van Lagen. Both have been awarded $1,000! Rodney is studying to become a secondary school teacher with a major in mathematics and a minor in English. Carley is currently enrolled in the Dental Assisting program at GRCC and plans on starting the Dental Hygiene program next fall.

We are very grateful to all the faculty and staff who have helped make these scholarships possible for Carley and Rodney. We wish these students all the best in their academic endeavors.

GRCC Mathematics Seminar Today in 114 Cook

The Grand Rapids Community College Mathematics Department is pleased to announce that it will host its first 2018-2019 Mathematics Seminar TODAY, September 26, from 3-4 p.m. in 114 Cook.

Our speaker is GRCC Mathematics Instructor John Dersch.

The study of mathematics has the potential to delight participants with beauty and surprising relationships. This talk will attempt to capture a small piece of mathematical wonder by connecting two ideas that appear to have nothing in common. Some knowledge of algebra will be useful, but, as always, everyone is welcome and encouraged to attend.

Refreshments will be served at 2:45 p.m.

 

Series and Probability DO Mix

Suppose you start adding 1 +     +      +    +  ¼  and you just keep going. As you add more and more terms, your answers will approach a unique number. It’s easy to approximate this number, but finding its exact value is a historically famous and fascinating problem.  This talk has two parts. In Part 1 we will show how Leonhard Euler first solved this famous problem in the 1730s. Part 2 reveals an unexpected appearance of Euler’s solution in our search for the answer to a question involving probability and relatively prime numbers.
