ICONIC REPRESENTATION AS STUDENT’S SUCCESS FACTOR IN ALGEBRAIC GENERALISATIONS
Abstract
Problems of finding general rule in the case of linear correspondences are often encountered in the research papers, where they are supplied with iconic means which support induction. And as the researchers report it, students have a tendency to focus solely on the numeric data even when visual patterns are given. The objective of our research is the examination of the influence of various iconic representations designed to help students establish and express general relations between quantities. This research is of empirical nature. The research was based on the testing technique. The obtained results show that iconic representation of the structure of algebraic contents influences greatly students’ ability of making generalisations and establishing algebraic relations and simple rules of correspondence. The very activity of drawing and iconic representing of the pattern members can also be seen as potentially significant for the discovering of the rule of correspondence and its generalisation.References
