Elaboración y aplicación de recursos didácticos y material concreto para optimizar el aprendizaje de la línea recta y la circunferencia en el tercer año de bachillerato de la especialidad de Mecanizado y Construcciones Metálicas del Instituto Técnico Andrés F. Córdova

Abstract

The proposal was to develop specific resources and materials for application in the classroom, in order to optimize the learning of the equation of the straight line and the circle. The teaching resources used were: GeoGebra software and PowerPoint slides, as to the specific material, wood and adhesive fomix built: strips to represent the straight line, circles of different diameters, puzzle sheets and the Cartesian plane. The project was developed in three months, each activity required two class periods forty minutes each. The student's classroom work was supported by the guide called "Learning Activity Book", which also included a self-assessment to encourage students to reflect on their own learning. Meanwhile the teacher continually evaluated teaching-learning process of the topics discussed, using the technique of observation and recording on a checklist specific material usage. Additionally assessment instruments were designed for inclusion in extra-class activities and class that allowed the teacher evaluation: the understanding of knowledge, development and practical application processes to solve real life problems. The implementation of this proposal favored the active participation of students in learning the equation of the straight line and the circle.
