Research Abstract |
In this study, I analyzed student's construction of meaning to mathematical notations with respect to proportion and explored the situations that foster their proportional reasoning. Results showed students' difficulties in developing appropriate meanings to tables, formulas and graphs for proportion. On the other hand, students were more familiar with tables compared with formulas and graphs and their use of tables functioned as scaffolding to construct meanings to other expressions. Results also showed the significance of situations in which students communicate each other through self-developed notations as medium. Based on the results, I made implications for lessons in which students interact positively with their mathematical notations.
