Dr. Campbell spent almost all of his professional career working in higher education in the fields of mathematics and mathematics education. During those 35 years he worked with students, future teachers, mathematics educators and administrators in a wide variety of capacities. He was Co-Director of the Missouri Mathematics Secondary & Middle Grades Leadership Academies (funded by US Dept of Education through MO DESE) working with Middle and Secondary mathematics teachers throughout the state. He was also Co-Director of a similar Missouri Elementary Mathematics Leadership Academy. He is a Past President of the Missouri Council of Teachers of Mathematics, among others, and has worked with numerous school districts throughout Missouri and the Midwest, and has been a speaker and workshop leader at dozens of state, regional, and national conferences. Most recently, he helped organize and spearhead work in Missouri that ended with a new add-on Missouri teaching certification for Elementary Mathematics Specialists, and is actively involved with a statewide 5-university collaborative that is preparing the first cohort of these Specialists.
Dr. Campbell won numerous teaching awards at the college, university, and state-wide levels. He believes that good, authentic (and even fun!) problem-solving and classroom environments can be an important key to helping students learn, understand, and make sense of the mathematics around them, and prepare them to use mathematics to solve the various daily problems of their adult lives. Dr. Campbell is still involved in professional development activities, and is available for a variety of topics, workshops, and longer-range work with teachers and school districts.
