PNA is a research journal in mathematics education published by the research group Didáctica de la Matemática: Pensamiento Numérico, FQM-193 of the Andalusian Plan of Research, Development and Innovation (PAIDI). Its goal is to promote and disseminate quality research at national and international levels. It is directed to researchers and education agents in the field. The articles published in PNA can be written in English or Spanish, follow the guidelines of the Publication Manual of the American Psychological Association (Sixth Edition), are double blind peer-reviewed and are also available in the PNA document database. We publish three articles per issue, and four issues per year, in January, March, June and September. PNA publishes both experimental and theoretical studies. The printed version of PNA is sent free to a reduced number of Spanish and international addressees.
