El aprendizaje de perímetro y área mediante una secuencia didáctica basada en proyectos bajo el Programa Escuela Nueva by Cubides Suárez, Wilson Javier

“…The field work began by means of a diagnostic test where the difficulties that students presented were observed when addressing area and perimeter issues, and then applied a didactic sequence that consisted of three learning guides elaborated from Learning Based on Projects (ABPr) with the Escuela Nueva - Escuela Activa (ENA) methodology in order to overcome the difficulties encountered in the diagnostic test and thus end with the application of the final test, which allowed assessing its impact on the student learning with respect to the mathematical objects posed. After describing the results obtained in the diagnostic test, the didactic sequence and the final test, a statistical study of the data collected in the two tests was carried out by means of the Wilcoxon test and T-student, to verify the degree reliability of the averages obtained, which helped to conclude that the didactic strategies supported by the ABPr and the ENA have a positive impact on the management of the concepts of perimeter and area of rectangles and right triangles, due to the elements that the context has rural such as the school garden, in addition to the meaningful learning of the students in the long term.…”
