Nerida F. Ellerton has been Professor within the Mathematics Department at Illinois State University since 2002. She holds two doctoral degrees-one in Physical Chemistry and the other in Mathematics Education.
Between 1997 and 2002 Nerida was Dean of Education at the University of Southern Queensland, Australia. She has taught in schools and at four universities, and has also served as consultant in numerous countries, including Australia, Bangladesh, Brunei Darussalam, China, Malaysia, the Philippines, Thailand, the United States of America, and Vietnam. She has written or edited 16 books and has had more than 150 articles published in refereed journals or edited collections. Between 1993 and 1997 she was editor of the Mathematics Education Research Journal, and between 2011 and 2015 she was Associate Educator of the Journal for Research in Mathematics Education.
In recent years Nerida has concentrated her research efforts in two areas-the history of schoolmathematics and problem posing in mathematics education. In 2012, 2014, and 2015, respectively, Springer published the 223-page Rewriting the History of School Mathematics in North America 1607-1861, the 367-page Abraham Lincoln's Cyphering Book and Ten other Extraordinary Cyphering Books, and the 204-page Thomas Jefferson and his Decimals: Neglected Years in the History of U.S. School Mathematics. She jointly authored each of those books with M. A. (Ken) Clements.
In 2015 Springer published a 567-page edited collection on problem posing which was jointly edited by Florence Mihaela Singer, Nerida, and Jinfa Cai. In 2015 Nerida received the outstanding researcher award of the College of Arts and Science at Illinois State University.
M. A. (Ken) Clements' masters and doctoral degrees were from the University of Melbourne, and at various times in his career he has taught, full-time, in primary and secondary schools, for a total of 15 years. He has taught in six universities, located in three nations, and since 2005 has been Associate Professor (2005-2006) and then Professor (2007-present) within the Mathematics Department at Illinois State University. Ken has served as a consultant and as a researcher in Australia, Brunei Darussalam, China, India, Malaysia, Papua New Guinea, South Africa, Thailand, the United Kingdom, the United States of America, and Vietnam. He served as co-editor of the three International Handbooks of Mathematics Education-published by Springer in 1996, 2003 and 2013-and, with Nerida Ellerton, co-authored a book on mathematics education research which was published by UNESCO in 1996.
Ken has authored or edited 32 books and over 200 articles on mathematics education, and is honorary life member of both the Mathematical Association of Victoria and the Mathematics Education Research Group of Australasia. During recent years Springer has published four books on the history of school mathematics jointly authored by Ken and his wife, Nerida Ellerton.
Ken and Nerida plan to return to their homeland, Australia, in 2017, where they expect to resume their work as co-directors of their Australian Heritage Education Museum-which is in Toowoomba, in the state of Queensland. The Museum will have wide-ranging themes, covering areas such as sport, music, sewing, technologies, mathematics, language, science, geography, history, colonialism, the influence of America on education in Australia, British influences on Australian education, one-room schoolhouses, Kindergarten, primary schools, secondary schools, tertiary education, distance education, and equity and educational opportunities.
In October 2015 Ken delivered a "distinguished lectureship" presentation for the College of Arts and Sciences at Illinois State University.
