How Students’ Abstraction in Constructing the Relationships between Parallelograms and Rhombus
Hodiyanto,, Mega Teguh Budiarto, Rooselyna Ekawati, Gemi Susanti
ABSTRACT:
This study describes students’ abstraction in constructing the relationship between parallelograms and rhombuses. A case study was used as the research method. One eighth-grade student who has studied quadrilateral material was the subject of this study. Because the researchers sought to go deeper into the subject’s abstraction, they only studied one subject for this study. The researchers were the main instrument. Assignments, geometric ability tests, and interview guidelines were the auxiliary instruments. In addition, because the researchers watched the subject’s gestures during the interview, they recorded every action the subject took. The findings demonstrated that the subject constructed the relationship between parallelograms and rhombuses using the epistemic actions of recognizing, building-with, and constructing (RBC). The subject uses gestures to understand others easily and herself, giving her more confidence. Further research should examine the subject’s consolidation after the subject constructs the relationship between a rhombus and a parallelogram. Consolidation of the constructs the subject has generated is necessary.
