Visualization Of Students In Constructing The Concept Of Fractions

[Full Text]



Henry Kurniawan



Visualization, construction, fraction concept



The fundamental aspect of fractional learning is to instill a profound fractional concept so that it can apply it to real situations and experience the fractional benefits in everyday life. Understanding the concept of fractions is the result of construction of the fractional objects. The construction of this fractional concept is done through visualization that manipulates the making of drawings, diagrams or animations for the appearance of fractional information. This research is a qualitative study that describes the construction of fractional concepts as equal parts of the whole and the construction of a fractional concept of value. Subjects in this study as many as 9 selected students from 22 students are grouped into 3 groups, namely (1) failed construction groups and true visualization; (2) failed construction group and failed visualization; and (3) true construction group and true visualization. The results of this study are group (1) the visualization has followed the appropriate pattern but is less precise in the calculation, the group (2) does not understand the concept of fraction so that it fails to visualize, and group (3) can already visualize the concept of fractions with different visualization form from the pattern.
