Research Abstract |
Many currently used approaches to early algebra appear to focus exclusively on introducing frame words and later literal symbols as devices for solving simple number sentences. What is often missing is that algebraic thinking necessarily involves students in patterns of generalized thinking. This study try to present several important approaches to introducing algebraic thinking in the elementary and junior high school curriculum using numerical expressions leading to a concept of a quasi-variable. The educational value of quasi-variable reported at international conference held at Australia, University of Melbourne, December9-14, 2001, titled : Fostering an understanding of algebraic generalization through numerical expressions : The role of quasi-variable, in K.Stacey eds., the Future of the Teaching and Learning of Algebra (ISBN O-9579673-0-6)pp.258-264 Also, results of interview with children reported at international conference held at Singapore, titled : Coating a bridge between early algebra and arithmetic through quasi-variable expressions., May 27-31, 2002, in Proceedings of Mathematics Education for a Knowledge- Based Era, Vol.2, pp.78-86.
