2018 Summer STEM Academy @UCA

Nineteen students from Conway and Little Rock middle and high school students attended 2018 Summer STEM Academic at UCA from June 25 through June 29, 2018. The academy was organized by the Department of Mathematics and the UCA STEM Institute.   Students participated in three inter-connected activities in biology, statistics and computer coding. The activities started at 9:15 AM and concluded at 3 PM every day with 1-hour lunch break.

The Data Analysis & Visualization activity, taught by Dr. Mark Doderer from the Computer Science Department, helped students develop computer programming skills and tools to analyze and visualize the data.   Empirical Modeling Analysis, instructed by Dr. Todd Abel of the Mathematics Department, introduced students to statistical modeling and helped them utilize the tools to develop and carry out experiments.  Biology faculty Dr. Krista Peppers taught Toxicology & Microscopy to help students develop microscopy skills and implement their own investigation into whether ethanol impacts the heart rate for Daphnia magna, the water flea.

Students implemented the knowledge and tools gained over the course of the week, to conduct experiments and come up with resolutions based on the data found.  On the last day of research, the students divided up into groups and presented their findings to their peers, parents and faculty/staff.    All four groups agreed that the introduction of ethanol slowed the heart rate of the Daphnia magna and the higher the concertation of ethanol, the slower the heartbeat.  Once the water fleas were reintroduced into water without ethanol, the heart beat quickly recovered and returned to normalcy.

The students stated they had an amazing time and learned interesting things about water flea.  The students hope to use the knowledge, tools and experience gained from this program to help them in future discoveries.Math Admin Assistants Mrs. Jennifer Jones and  Mrs. Leitha Smith, and a  math graduate student  Eddie Gallarno provided additional support for the program.  For information about the future Summer STEM Academy or  similar programs, please contact the organizer Dr. Ramesh Garimella, Chair, Department of Mathematics at rameshg@uca.edu

State Math Contest Held on UCA Campus

On Saturday, April 28, 2018, the UCA Department of Mathematics hosted the annual State Mathematics Contest. It  was sponsored by the Arkansas Council of Teachers of Mathematics (ACTM).  There were 235 students from high schools across  Arkansas competed in one of six exam categories -Algebra I, Algebra II, Geometry, Trig/Pre-Calculus, Calculus and Statistics.  Dr. Charles Watson, Associate Professor of Mathematics, served as the director of the state contest  and was assisted by mathematics faculty members,Dr. Garth Johnson, Dr. Carolyn Pinchback, and Ms. Loi Booher, and graduate student Kayla Waters.  Exams were proctored by the UCA math graduate teaching assistants.

All students participated in the state contest  were top ten finishers in one of the 11 regional contests that were held in colleges and universities across the state on March 5, 2018. All students who placed in top three at the state level were awarded trophies.  Algebra I and Geometry winners received TI-84 calculators and the other contest winners received scholarship awards to a future college of their choice. Awards were presented by Dr. Watson and Ms. Kim Hughes, president of ACTM.
