Visualizing the Concept Images of Students on Numbers with Combined SOM-Ward Clustering Analysis

Abstract: The purpose of the study is to perform a less-dimensional visualization process for the purpose of determining the images of the students on the concept of number. The Ward clustering analysis combined with the self-organizing map (SOM) was used for this purpose. The conceptual understanding tool, which consisted of the open-ended question "write the first ten things you remember when the term number is mentioned" to the study group, which consisted of 212 fifth grade students.

“…Ward's method of clustering proved to be the most appropriate. It belongs among the hierarchical methods of clustering, and it is trying to optimize the loss of information that may occur by uniting two clusters (Kaya et al, 2017). First, each element is independent, and then step by step.…”
