Sensores y apps en el estudio de la escala logarítmica

En esta propuesta para el desarrollo profesional de los profesores a partir de una revision a estudios concernientes al caracter social de aprender, junto con el desarrollo historico- epistemologico de conceptos, se indaga la relacion entre las progresiones geometricas y aritmeticas y, se realiza una invitacion de aprendizaje dirigida a los profesores de Precalculo. Ella lleva entrelazado un ambiente de laboratorio, haciendo uso de sensores y apps, en el analisis de los casos de la escala logaritmica musical y del pH.  Se usa la metodologia de analisis de contenido con el fin de esbozar caminos concernientes a ?De que maneras, los profesores universitarios de Precalculo, pueden acercarse a la comprension y caracterizacion de las funciones logaritmicas? Palabras clave: sensores, apps, escala logaritmica, profesor, social, formacion. Abstract In this proposal for teacher’s professional development from a revision of some studies regarding the social character of learning, along with development of historic –epistemological concepts, it is explored the relation between geometrical and arithmetical progressions and it is extended an invitation of learning addressed to Precalculus teachers. This one has intertwined a laboratory environment, making use of sensors and apps, in the analysis of logarithmic musical scale cases and in the pH. It is used the content analysis methodology with the purpose of sketching some ways with regarding to the question: In which ways the Precalculus university teachers are able to approach to the comprehension and characterization of the logarithmic funtions? Key Words: sensors, apps, logarithmic scale, teacher, social, formation SUMMARY In this proposal for teacher’s professional development from a revision of some studies regarding the social character of learning, along with development of historic –epistemological concepts, it is explored the relation between geometrical and arithmetical progressions and it is extended an invitation of learning addressed to Precalculus teachers.
