MARES, Guadalupe et al. Textos y la manera de trabajarlos: su impacto en el aprendizaje de alumnos de segundo de primaria. RMIE [online]. 2009, vol.14, n.40, pp.93-119. ISSN 1405-6666.

This article describes the evaluation of second-graders' linguistic skills in biology, and the comparison of execution involving two types of texts: one prepared by the Secretary of Public Education (SEP)-and its teaching strategy-and another modified text associated with two strategies derived from interbehavioral psychology. The participants were thirty-six children assigned to three groups: G1, SEP text and official strategy; G2, modified text and integration of skill; and G3, modified text and promotion of deductions. A pretest-intervention-posttest design was used with the three groups; the results indicate that significant differences between the two evaluations were found only in G3. On comparing the three groups, only G3 surpassed G1 in a significant manner. The progress in skills by concept are analyzed in terms of their possible relations with the texts and the strategies employed in each group.
