Analysing Profiles of Recognition in Graph Theory

In this work, we explore the recognition skills in graph theory of undergraduate stu-dents of the degree in Computer Science-Information Technology of the University of Seville. For this purpose, we design a questionnaire that we use as an instrument for data collection, which are subsequently analysed by means of an adaptation of the methodology of the calculation of the degrees of acquisition, giving rise to different profiles of recognition in graph theory. The characteristics of these profiles allow us to give empirical support to a theoretical proposal of recognition levels in graph theory from the perspective of the Van Hiele model, as well as to draw some conclusions about aspects of teaching and learning this field of mathematics.
