StemSchool Inc. was incorporated November 17, 2007 as an Indiana non-profit corporation. To apply for federal 501(c)(3) federal tax-exempt status costs $300---we haven't done that yet.
Mark Senn attended K-12 at Lafayette School Corporation (LSC) in Lafayette IN. Sick of excruciatingly disinteresting classes and turned off on school in general, he graduated a semester early from Jefferson High School to became a helicopter mechanic. In California he met some college math teachers that made math interesting and fun by having students discover things for themselves. He took classes, started tutoring students in grades 4-12 to earn extra money, and has continued to help students occasionally since then for free. Sometime around 1980 he worked as a substitute teacher for LSC.
In 1983 he earned a Bachelor of Science in Engineering with Distinction in Interdisciplinary Engineering from Purdue University. He now works as a systems programmer for the Engineering Computer Network at Purdue University. His duties include helping people with Mathematica.
In October 2006, high school teacher Abby Brown (San Diego CA) and some of her students gave presentations at a Mathematica conference. Mark left the conference energized to try to duplicate Abby's success here.
Mark contacted West Lafayette High School during their fall semester in 2006. He demonstrated Mathematica to their math and science teachers and arranged for a grant to get it. They started using it during the fall semester of 2007.
