Goro Shimura's profound observation about his colleague, Yutaka Taniyama, appears as the subtitle of this blog;

*"He was not a very careful person as a mathematician. He made a lot of mistakes. But he made mistakes in a good direction. I tried to emulate him. But I've realized that it's very difficult to make good mistakes."* If you'd like to know more about the Taniyama-Shimura conjecture, read this.

My name is Mr. Shelby Aaberg. This is my 13th year teaching high school mathematics at Scottsbluff High School in Scottsbluff, Nebraska. I am the 2015 Nebraska Teacher of the Year. I am a National Board Certified Teacher and a Presidential Awardee for Excellence in Mathematics & Science Teaching. I serve as the math department chair at SHS. I am a Ed.D student and an adjunct instructor at the University of Nebraska-Lincoln. My research interests include statistics education, teacher education & preparation programs, and professional development for middle school and high school mathematics teachers. I am also in my eleventh year coaching boys' and girls' sprints and hold a Level 2 Certification in Sprints, Hurdles, and Relays from USA Track & Field.

Teaching well is hard and requires careful planning and reflection. This blog reflects views on teaching and learning which are my own and do not necessarily reflect those of my employers nor the University I attend.

My current teaching assignment includes AP Statistics, Advanced Algebra 2, Mathematical Applications of STEM Careers, Math Club, and Math Theory & Problem Solving.
