Analysing the Semiotic Complexity of Graphs Produced by Future Primary School Teachers in a Task Related to the Comparison of Two Statistical Variables

Abstract

In this paper, we analyse the graphs produced by 93 prospective primary school teachers in a task comparing two statistical variables. We define a level of semiotic complexity that serves to classify the graphs produced. We relate this level to the level in reading the graphs and the conclusion obtained. Results show that only some participants produce a graph with enough complexity to get an adequate conclusion and part of them either do not reach an adequate level of reading or do not get a complete conclusion in relation to the research question.
