![]() Of course, this is meant to complement, not replace other approaches to these ideas. On this page, I introduce function diagrams, and provide a number of lessons and activities to use them at various levels in secondary school. ![]() I was inspired to develop some lessons for the textbook I co-authored with Anita Wah ( Algebra: Themes, Tools, Concepts - ATTC), using the name "function diagrams" for that representation. ![]() I heard about it in a talk by Martin Flashman. One underused representation of functions, which I have found educationally rich, is the one with parallel x and y axes. (See for example the article A New Algebra, and the graphing calculator lessons on this site.) These changes are motivated in part by the availability of electronic graphers, and in part by sound pedagogical thinking: different representations are more accessible to different students, and the ability to switch representations both reflects and facilitates depth of understanding for all students. Two major features of recent math curricula are * the increased emphasis on functions throughout secondary school, and * their multiple representations: numerical, graphical, and symbolic.
