INEQUALITIES AND EQUATIONS: HISTORY AND DIDACTICS
In Bosch, M. (Ed.). Proceedings of CERME 4. Sant Feliu de Gu xols 2005, 652 662. INEQUALITIES AND equations : HISTORY AND DIDACTICS . Giorgio T. Bagni Department of Mathematics and Computer Science, University of Udine (Italy). Abstract. The historical development of equations and INEQUALITIES is examined, in order to underline their very different roles in various socio-cultural contexts. From the educational point of view, historical differences must be adequately taken into account: as a matter of fact, a forced analogy between equations and INEQUALITIES , in procedural sense, would cause some dangerous phenomena. 1. Introduction: algebraic equations and INEQUALITIES Frequently, from the educational point of view, algebraic INEQUALITIES are introduced to pupils after algebraic equations , and the solving techniques are strictly compared.
