Las inferencias en la comprensión de problemas aritméticos en la enseñanza primaria Karel Pérez Ariza José Emilio Hernández Sánchez Maurén Álvarez Pérez Educación inferencias comprensión lectora Problemas aritméticos El trabajo con problemas aritméticos constituye un objetivo de especial interés en la enseñanza primaria. Diversos autores coinciden en reconocer que la comprensión es el aspecto más afectado en la referida actividad, la cual se basa esencialmente en la elaboración de inferencias. Lo antes expuesto permite deducir la necesidad de favorecer la elaboración de inferencias en el proceso de comprensión de problemas aritméticos verbales. Consecuentemente con ello el objetivo del trabajo va dirigido a ofrecer procedimientos didácticos que favorezcan el desarrollo de la comprensión de problemas aritméticos verbales en escolares primarios. 2015 artículo científico 0864-196X https://www.redalyc.org/articulo.oa?id=360643422021 es http://www.redalyc.org/revista.oa?id=3606 VARONA application/pdf Universidad Pedagógica Enrique José Varona VARONA (Cuba) Num.61
