John Dossey attended Illinois State University, receiving his BS and MS in mathematics there. He began his teaching career at the junior high school level, later moving to high school, and then accepting a position as a K-12 mathematics coordinator for the Normal, Illinois public schools. John completed his PhD in mathematics education at the University of Illinois at Urbana-Champaign. By this time, he was already teaching mathematics and mathematics education classes in the Department of Mathematics at Illinois State University. At Illinois State, he moved through the ranks, becoming Distinguished University Professor of Mathematics. He became involved in a variety of activities involving state, national (NAEP, ACT, and SAT), and international (SIMS, TIMSS, & PISA) student assessments. With this experience, John went on to author or co-author over 80 books ranging from middle school through collegiate mathematics, including methods texts for preservice teachers and professional development titles on assessment and curriculum.

John served as president of the National Council of Teachers of Mathematics, and helped lead the development of the initial NCTM Standards. He served as chair of the Conference Board for the Mathematical Sciences in Washington, D.C.; as Distinguished Visiting Professor of Mathematics at the U.S. Military Academy at West Point, NY; and as a member of many national and international committees and boards dealing with mathematics and mathematics education issues. Away from his professional life, John and his wife, Anne, enjoy living in the country, traveling, and getting together with friends.

Jane Faith Schielack first discovered her love of mathematics in elementary school and it continued to grow throughout her life. She received her BS in Education from Texas A&M University, with certification in Mathematics and English in grades 1-12. After teaching third grade in Victoria, Texas, Janie earned an MA in Mathematics Education from the University of Texas at Austin and became the elementary mathematics consultant at the Texas Education Agency. Later, she returned to Texas A&M University for her PhD in mathematics education while working as a lecturer there in the mathematics courses for elementary and secondary education majors.

Now a professor in mathematics and education at Texas A&M University, Janie has continued her involvement with the Texas Education Agency's development of the state-mandated curriculum in mathematics; made hundreds of presentations at mathematics conferences for teachers; written and presented a variety of professional development institutes for in-service teachers; and authored articles and textbooks focusing on helping children understand mathematics.

Janie spends her free time enjoying her family. She unabashedly admits to using her children as instructional guinea pigs and handy sources of data on learning.
