Técnica vocal, Sound Analysis Oscilloscope y Sound Analyzer para la enseñanza de las magnitudes físicas de las ondas en estudiantes de grado octavo del Colegio Agustiniano Salitre

Abstract

In this work a didactic strategy was designed to teach the physical magnitudes of the waves using vocal technique exercises and two Sound Analysis Oscilloscope and Sound Analyzer App cell applications, which measure the frequency, period, wavelength and volume with decibels of sounds in order to improve the empathy towards the sciences and the analysis of the waves in eighth grade students of the Colegio Agustiniano Ciudad Salitre. To this end, a theoretical framework on education, waves, vocal technique, and research methodology was consolidated, followed by the design of an analysis instrument (survey) to evaluate several items: the students' interest in the class, the understanding of the topics and the relationship between the contents seen specifically of the characteristics of the waves in the sound in eighth grade students of the school who do not approve the period in which wave physics was analyzed to realize the empathy recognition and the difficulties in the contents using traditional method.
