Dimensiones tecnológicas en tareas de libros de texto de matemáticas.

The mathematics curriculum for lower secondary education stipulates that technology should not only provide a means of information and communication but also support key learning. However, for various reasons, the scope of technology in classrooms is limited. This research examines 189 mathematics tasks from eight textbooks, each using technology. The tasks were classified based on expected learning in one of three technological dimensions (informational, technical or didactic) by means of content analysis. The results show differences both between textbooks following the SEP 2011 and SEP 2017 models and between content areas. There is, however, a positive trend toward promoting a well-reasoned use of technology in the classroom. Conversely, the study also identified difficulties that may serve as guidelines for teachers, publishers, and authorities in using, publishing, and selecting textbooks, respectively.
