Distinguished Mathematics Educator


Meet the 2025 WMC Distinguished Mathematics Educators 

Mike Weidner

Mike earned his Undergraduate and Masters Degrees from Marquette University, followed by an additional Masters in Curriculum and Instruction from UW Milwaukee.  He has taught at Nicolet High School from 1993 to the present day, and will be retiring at the end of this school year.  While at Nicolet, he has consistently advocated for reform mathematics, using technology in the classroom, student-centered instruction, assessment reform, discovery learning and curricular

innovation.  Mike has also shared his knowledge and expertise with mathematics educators throughout Wisconsin by leading numerous summer academies, as well as teaching classes through Alverno College, Marquette University, and Concordia University.  He has also presented and led workshops through NCTM and Texas Instruments, and has presented at the WMC Annual Conference numerous times.

Mike served on the WMC Board for ten years, including six as treasurer.  He was pivotal in establishing the Wisconsin Mathematics Education Foundation, and served on their Board from 2010 to 2024.  His interests as a teacher have always had students and their learning at the core.  He has always strived to bring out the very best mathematical thinking from his students as well as their best attributes as human beings.  While mathematics has always been the medium of his teaching, Mike never lost sight of the fact that he was charged with the mighty and wonderful task of teaching children.

Arnold Chandler

Arnold started his professional career as a high school mathematics teacher at East High School in Rockford, IL, and at the UW High School. He obtained a Master’s Degree and PhD in mathematics education from the University of Wisconsin-Madison. He was the first mathematics supervisor at the Wisconsin Department of Public Instruction, later a bureau director overseeing all core subjects, and served for a time as assistant superintendent of public schools in Wisconsin.  Arnold was one of the founders of the Association of State Supervisors of Mathematics, and in 1962 he was elected its second president. In 1965 he became president of the Wisconsin Mathematics Council.

Arnold understood the limitations of traditional mathematics instruction and was supportive of making wholesale changes to the mathematics curriculum. Those changes revolved around shifting the emphasis of mathematics teaching from learning computational procedures to understanding mathematics concepts.  He was immensely proud of public education in Wisconsin and was always excited to discuss his time spent in nearly every community and school district in the state.  Arnold passed away on July 26, 2019 at the age of 89.
