Efecto del modelo de barras en el desarrollo de la competencia de resolución de problemas en estudiantes de sexto grado de la institución educativa María Auxiliadora de Galapa

This research seeks to evaluate the Bar Model Effect on Development Solving Problems Skill in Six Grade’s Students of Galapa’s Institución Educativa María Auxiliadora, looking for an alternative to contribute in the difficulties observed in the Saber 11th Tests, where it was found that students have limitations in following instructions and selecting algorithms to solve the proposed problems properly. Therefore, a pedagogical proposal is developed with a set of nine (9) didactic guides in order to approach the procedures for problems solution and use the bar model method, to provide students with a different experience which permit to model problem situations depending on the types of operations required for solution that problem, then they apply the bar model method to later propose and solve the equation. Two assessment instruments were designed: the pre-test and the post-test. The pre-test instrument allowed to establish the level of problem-solving competencies that sixth-grade students possess and to identify how they addressed a problem situation, which strategies they applied. The post-test allowed assessing the impact of the implementation of the strategy and determining the progress in the development of the problem-solving competence. Among the results obtained, it is important to have developed in the student’s skills for the interpretation, modeling, proposing and resolution of problem situations, to awaken interest and motivation in students to find the solution to situations posed by following the steps in Polya´s Method (1998). Finally, it was concluded that the strategies used by the teacher contribute in the way that the student reaches the proposed competences
