Linhart was part of an international cohort that developed materials to support methods of teaching differential equations.</p><p>Linhart created a project that explores ballistics modeling; specifically how different models of air resistance change the theoretical trajectory of an object, comparing theory with experimental data.</p><p>“The project I worked on involved modeling the trajectory of a sponge dart,” said Linhart. “Students can inexpensively collect their own data, and then use mathematics to see how different mathematical models of air resistance change the theoretical trajectory of the dart, and how well theory matches up with the data.”</p><p>Participants experienced new activities for teaching with real world scenarios through presentations and teaching experiences. They investigated applying mathematics to such areas as biology, chemistry, economics, and engineering. Through peer review, conversations, and quiet time devoted to writing, participants produced innovative teaching materials for online publishing and distribution.</p><p>The organization, SIMIODE (Systemic Initiative for Modeling Investigations and Opportunities with Differential Equations), sponsored the week-long workshop to support using modeling in teaching differential equations, a pivotal STEM (science, technology, education, math) course in the undergraduate curriculum.

According to her professors, she is an exceptional student who has taken on every challenge the actuarial science program has to offer, with a gusto that is infectious not only to her fellow students but also to her instructors.</p><p>Actuarial science is a discipline that assesses financial risks in the health, insurance, and finance fields, using mathematical and statistical methods.</p><p>“I first got into math in the Running Start program [at Yakima's AC Davis High School],” Charron said. “My teacher, Carolyn Schut, suggested that actuarial science might be a good career choice."</p><p>Charron, who transferred here from Yakima Valley College in fall 2015 with an associate’s degree through Running Start, took to the program with alacrity.</p><p>“I transferred here as a junior, and decided to slow down a little bit to get a more rounded education,” she continued. To balance and complement her mathematics curriculum, Charron took finance, computer science, and economics courses.</p><p>In three years at CWU, she has taken all of the courses for an actuarial science major plus an additional year of senior-level coursework. She has completed minors in finance and economics, served as president of the Actuarial Science Club, and passed three of the rigorous professional exams from the Society of Actuaries—all with a near 4.0 GPA at CWU. Charron was honored for her scholarship at the College of the Sciences Awards Banquet on May 3.</p><p>“I really enjoy it. It’s rewarding how challenging it is,” Charron said. “You have to study nine months straight to pass one exam.”</p><p>To be certified as an actuary, one must past a series of rigorous exams. In the CWU program, students usually make headway by passing one or two before graduation.</p><p>“Three exams down and three to go,” she grinned. “The pressure is off a little.”</p><p>It was her extra diligence that gained her a job offer after graduation. Lisa will be joining the international consulting firm, Milliman Inc., in Seattle.</p><p>“It’s an actuarial firm, you know, nerds that consult other nerds,” she laughed.</p><p>“I came to Central because it was close to home, and had one of the most esteemed actuarial programs on the West Coast. And not having to pay out-of-state tuition was a big plus, too.”</p><p>Lisa is the daughter of renowned Yakima architect Nancy Charron, of Traho Architects, PS. Lisa’s sister Monica will also walk the boards on Saturday, graduating with a degree in Food Science and Nutrition.</p><p>When she’s not computing risks, or checking statistics, you can find Lisa hiking or rock climbing, usually with her golden retriever, Autumn.</p><p>“Being at Central has been amazing, and I loved all my classes,” Charron beamed. “My teachers let me shine and be as enthusiastic as I wanted.”</p><p><em>CWU's Actuarial Science Program is the only major program offered in the State of Washington and one of very few on the US West Coast. It is ranked as an advanced undergraduate program by the Society of Actuaries.</em></p><p>Media Contact: Valerie Chapman-Stockwell, Public Affairs, 509-963-1518, valeriec@cwu.edu</p><p>&nbsp;</p>2018 Kryptos Challenge Attracts Participants from Around the Worldhttps://www.cwu.edu/math/node/2716Wed, 18 Apr 2018 11:13:21<p><img alt="" src="/math/sites/cts.cwu.edu.math/files/images/kryptos.jpg" style="width: 441px; height: 114px;"></p><p>The annual International Kryptos Challenge, hosted by the Central Washington University Department of Mathematics, boasted 143 participants, forming 61 teams. They represented colleges, universities, and schools from throughout the United States, including Arizona, California, Florida, Idaho, Iowa, Kentucky, Massachusetts, Nevada, New York, North Carolina, Ohio, Oregon, Pennsylvania, Vermont, Virginia, and Washington. Students from Canada and France also participated.</p><p>“We continue to have a lot of interest in this event,” said Stuart Boersma, professor and chair of mathematics, and co-founder of the Kryptos Challenge. Boersma has been running the challenge since 2011.</p><p>The contest centers on the breaking, or cryptanalysis, of secret writing, or ciphers. Each challenge presents contestants with a brief scenario together with an encoded message—ciphertext. The goal is to discover the original English plaintext message. This year, participants decrypted puzzling personal ads, unscrambled an intriguing invitation, and broke up a fictional internet trolling ring. The challenge was developed by Boersma, and his colleague, Cheryl Beaver, a Western Oregon University mathematics professor.</p><p>The first-place team, from Eastern Mennonite University in Virginia, finished in just under 20 hours.</p><p>“I think the problems were a little more challenging this year,” Boersma said. “But the main objective is to have fun. Most students with a little familiarity with ciphers or code-breaking can solve the challenges. They aren’t overly technical, nor do they use advanced mathematical algorithms.”</p><p>The contest is sponsored by the Pacific Northwest section of the Mathematical Association of America and is held every April. The 2018 challenge was held April 5 through April 9.

Kathryn Temple, Central Washington University mathematics and actuarial science professor, completed a decade of passing a rigorous series of professional examinations to achieve this honor.</p><p>Actuaries are professionals who develop and communicate solutions for complex financial issues such as risk management for banking and insurance industries.</p><p>"I started taking the exams for the Associate level soon after I first arrived," Temple said. "They corresponded to the financial mathematics courses I was teaching at the time."</p><p>She is the second professor at CWU to achieve an Associate distinction; Yvonne Chueh, also a mathematics professor, achieved the level in 1994. CWU is the only school in Washington State and one of only a handful in the Pacific Northwest to offer an actuarial science major. It is the only school in the region that can boast two professors who are Associates in the Society.</p><p>"The modules are modeled on professional cases," she continued. "The "real-life" scenarios make it easy for students to relate to, and I can emphasize other aspects of the test, such as communication skills."</p><p>Students in the actuarial sciences program usually pass one to two examinations by the time they graduate, according to Temple. Students need to pass five exams to become a credentialed actuary, and many will continue to work on examinations throughout the early years of their career.</p><p>"There are at least 40-50 declared majors in the program," Temple noted. "And we graduate up to 15 per year. Our "cohort" is small enough that we really get to know and support one another."</p><p>In addition to teaching actuarial science and upper-level courses for math majors, Temple also enjoys teaching math to non-majors and students from other departments.</p><p>"I like to make math useful and relevant for people who are going to do other things," she smiled.</p><p>A Washington native, Temple grew up outside of Spokane. She received her BS from the University of Washington, and her PhD in mathematics from the University of Wisconsin-Madison. She has been teaching at CWU for 13 years.</p><p><strong>CWU's Actuarial Science Program</strong><br>CWU is the only institution in Washington-and one of only three in the Pacific Northwest-that offers a bachelor of science degree in actuarial science. It is ranked as an advanced undergraduate program by the Society of Actuaries, as the program is designed to prepare students for the rigorous actuarial examinations. The program covers the material for the five preliminary examinations, with the typical student finishing the material for four of the five preliminary exams before graduation.

Klyve, associate professor of mathematics at Central Washington University, will speak on Leonhard Euler, a Swiss mathematical genius and renaissance man who lived from 1707 to1783.</p><p>The Heilman Colloquium speaker is chosen for distinction in scholarship and a dedication to undergraduate research. In addition to giving the first annual Colloquium, Klyve will serve as an external mentor to a Quest student pursuing research in the history of mathematics, and participate in the university’s scholarship conference.</p><p>Klyve is a Euler scholar, who developed the online "Euler Archive," and has been instrumental in bringing Euler's many works (on so many different subjects) to light.</p><p>"I am honored to be invited to be the first speaker at this colloquium," Klyve said. "I continue to believe that the work of Euler should be more broadly known, and I appreciate the opportunity to share some of it with this audience. I’m also pleased to be able to support Quest, a university I love, and one which reminds me a lot of CWU’s own Douglas Honors College."</p><p>In addition to being a mathematician, Euler was a world-class physicist, astronomer, and a leader in fluid dynamics. It’s less well known that Euler wrote philosophy and theology and studied music, as well. Klyve’s own work has demonstrated Euler’s early role in linguistics, and has elucidated Euler’s work in demography and population studies, which led indirectly to Darwin’s theory of natural selection.</p><p>In his talk, Klyve plans to examine the some of the highlights from Euler’s lesser-known works, and draw some insights into the value of interdisciplinary thinking today.</p><p>A prolific author, Klyve has written more than 40 papers in number theory, the history of mathematics and science, and applied statistics—several of which have been co-authored with his students. He was recently named editor of the <em>College Math Journal</em>, one of the most widely read mathematics journals in the world.</p><p>In 2015, he received a $1.5 million grant from the National Science Foundation to develop math curriculum based on primary historical sources.</p><p>An expert in eighteenth century science, Klyve has written on the mathematics, astronomy, biology, linguistics, and philosophy of the period. He has spoken on the history of math and science across the country and around the world. In 2014, the MAA selected Dominic Klyve with the Alder Award, a national teaching award for young faculty who have a demonstrated impact within and beyond the classroom.</p><p><strong>Quest University</strong><br>In 2002, Quest University Canada is Canada’s first independent, not-for-profit, secular university.

The two Central Washington University professors are dedicated to promoting science education and furthering public understanding in all areas of science.</p><p>Kaspari, whose work examines the effect of black carbon (soot, a common air pollutant) on snow fields and ice melt, will speak about climate science in Washington State. One of her research projects examined the increased snow melt on Table Mountain due to black carbon, and its impact on wildfires.</p><p>"We need to know how to make progress on limiting climate change during a time when climate change science has been politicized," she declared. Kaspari also heads the ice-core laboratory that documents recent environmental change related to human activities.</p><p>Klyve, whose work with students has resulted in them discovering the world's largest weird number (among other things), has been nationally recognized for his teaching excellence. He recently received a $1.5 million grant to develop an innovative math curriculum based on primary historical sources.</p><p>Klyve will speak about the history of government and science, including the oldest scientific organization, the Royal Society for Improving Natural Knowledge in England.&nbsp;</p><p>"History shows us that government can be a powerful force for good in society when it promotes science and leaves scientists free to practice their craft," Klyve said. "These lessons are still important today, maybe more now than ever."</p><p>The Earth Day March for Science in Ellensburg will begin gathering at noon the US Post Office, 100 E. 3rd Avenue.

Central Washington University Professor Aaron Montgomery recently received the Distinguished College or University Teaching of Mathematics Award. The honor, given by the Pacific Northwest section of the Mathematical Association of America, is bestowed on "teachers of mathematics who are widely recognized as extraordinarily successful."</p><p>Montgomery, who has been teaching math at CWU for 16 years, stands out as "one of the best with respect to his devotion to teaching and exploring ways to support students," according to department chair Stuart Boersma (also an MAA award recipient).</p><p>Known as a versatile instructor—he teaches everything from 100 level general education math classes to graduate courses—Montgomery also has a knack for creating comprehensive courses that combine everything from mathematical modeling to anthropology. His very popular "Politics and Games" course that he teaches through the William O. Douglas Honors College, draws from philosophy, psychology, and economics as well as political science and game theory. According to Boersma, these courses are usually only taught once or twice—"but Aaron has taught this course&nbsp;eight times for the DHC since the fall of 2010."</p><p>One of Montgomery's main interests is in the field of quantitative literacy.</p><p>"This is really the goal of applied mathematics," Montgomery explained. “This is the ability to work with the numbers that we encounter on a daily basis — percentages, that kind of thing. And it is applicable both professionally and personally.<br>"For example, if you are asked to take a 10 percent pay cut, with the promise of a 10 percent pay increase later, is your situation stable or are you losing money?"</p><p>Montgomery enjoys creating puzzles to educate students in these and other mathematical principles.</p><p>He has also made meaningful contributions to mathematics teaching on a national level, authoring innovative curriculum, and developing assessment tools to better understand students' reasoning abilities.</p><p>Montgomery will receive the MAA award this June at the annual meeting in Spokane. By winning the regional honor, he has been nominated for the national Deborah and Franklin Tepper Haimo Award.</p><p>This is the third award that CWU's Math department has received for outstanding teaching.

The current grant, SOAR3 (Success, Opportunity, Affordability and Rigor, Relevance and Relationships) serves students in the Brewster, Easton, Highland, Lake Chelan, Manson, Omak, Oroville, Quincy, Richland, Tonasket, and Wenatchee school districts.</p><p>“Participating in STEM competitions is a key component of the grant,” said Kelley Quirk, program manager. “Earlier this year, we took students to the VEX Robotics World Competition in Louisville, Kentucky.</p><p>On Tuesday, the students will take part in hands on math activities, led by CWU math professors, math students, and GEAR UP CWU student mentors. They will also take the American Math Challenge test (AMC 8). The AMC 8 is a 25-question, 40-minute, multiple-choice exam in middle school mathematics designed to promote the development of problem solving skills. The AMC 8 provides an opportunity for middle school students to develop positive attitudes towards analytical thinking and mathematics that can assist in future careers. Students apply classroom-learned skills to unique problem-solving challenges, in a low-stress friendly environment.</p><p>“Last year we had 200 students attend,” said Brandy Wiegers, math professor. “We will also provide a similar opportunity for 10th through 12th graders next year, on February 7, 2017.</p><p>“This year we’re going to again turn the day into a Math Festival,” she continued. “The idea is to surround the competition with fun and positive math vibes, and to introduce a whole lot of potential future students to our department.
