| Summary: | This article shows the results of a study on the educational practices related to Cartesian graphical representations. The results show that the researched teachers do very few activities that require the comprehension of the implicit information in the graph. Also, they show that the frequency with which the researched teachers do activities of interpretation of graphs that require the understanding of their conceptual information does not change according to the educational level. In addition, it is shown that the higher the academic level, the lower the number of activities based on the interpretation of Cartesian graphs. Further, it is pointed out that the teachers frequently use Cartesian graphs with adjusted and straight lines but do not frequently use Cartesian graphs with several, curved or unadjusted lines. Finally, results show that the researched teachers group believe that the students fail interpreting the graphs due to their lack of practice in doing this type of activities. |
