Resolución de funciones cuadráticas mediante el uso de objetos de aprendizaje por parte de estudiantes de segundo año de bachillerato, en la fase de retroalimentación

Abstract

The present proposal consisted of analyzing the impact of the Learning Objects (LO), as support in the teaching for the resolution of quadratic functions, in the feedback phase, of the second-year students of technical education in computer science of the Educational Unit "City of Girón". It is based on traditional and contemporary pedagogical models, with a mixed approach, of quasi-experimental design. The methodology consisted of choosing two study groups, one experimental to which the proposal was applied and another one of control; The two groups underwent a diagnostic evaluation to determine if they were on equal terms with respect to the knowledge of the quadratic function before the application of the LOs; concluding with a final evaluation to determine the impact of the proposal. The data was collected and tabulated; For the case of the diagnostic evaluation, parametric statistics were used by means of the T-Student test, whereas for the validation of the research hypothesis, the Mann Whitney U test was used. It was found that the use of Learning Objects in the feedback phase positively affects the teaching-learning process of the quadratic function, since the experimental group had better academic performance with respect to those of the control group, because the average of the experimental group exceeded by 1.90 points those of the control group.
