Estrategias metodológicas para el aprendizaje de medida en los estudiantes del 10mo “D” de educación básica del colegio Daniel Córdova Toral

Abstract

With the purpose to develop the nominated skills stated in the document “Updating and Strengthening Curriculum for the Tenth year of Basic Education,” the present research work has been designed and implemented methodological strategies for the teaching-learning process of the measurement. The strategies encompass length measurements, converting units of length in the English and International Systems, perimeter calculation and areas. This also includes measurement of angles in the sexagesimal and circular system. The strategies were developed on the basis of the Constructivism and Cognitivist teaching approaches of Piaget, Vigotscky and Ausubel, as well as on the proposals of Godino, Chamorro Batanero and Roar among other authors. In order to learn measurement effectively, a sequence is proposed. This sequence considers the knowledge construction processes which start with guided activities. They use concrete material, measuring instruments, real situations measures, and estimated activities for length and angle measures. The strategies were implemented through workshops. An application guide for teachers was also designed. It consists of material for the student, and observation guides to evaluate the skills. The last ones allow teachers to apply the observation technique with its corresponding matching list. The results (the descriptive analysis) after the implementation of the project, showed a positive value/outcome with respect to the applied strategies and the students´academic improvement.
