Grafiko estatistikoak Lehen Hezkuntzako euskarazko matematikako testuliburuetan

Resumen

Ikaselkar (Baga-Biga) and Erein editorials’ Elementary Education math textbooks are studied. The following was analyzed for each graph: the type of graph, the type of activity, the reading level and the semiotic complexity. In both editorials the bar graphs and the calculating and completing activities prevail. As regards to the level of readability, only activities reading the data and reading between the data appeared in Ikaselkar. Erein, on the other hand, adds some level of reading activities of level reading beyond the data (10.64 %). In terms of semiotic difficulties, Erein attributes the maximum weight to level data distribution representation (64.29 %), whereas Ikaselkar also offers space to level representation of a data set without representing the distribution in an attempt to reinforce the idea of a statistical variable.
