Cataloging information on where, how and when 1000 commonly used mathematics terms are used in primary and secondary school student mathematics textbooks. Examined 30 plus years of development. Some of the information has been put into my website - K-12math.info
I have taught, worked in teacher training programs and material development projects in the Philippines, Thailand and the United States. It is in the later capacity that has focused my present interests in designing bibliographic systems on elementary and secondary school math textbooks.
