Indicadores naturales como recursos para el aprendizaje de ácidos y bases con estudiantes de segundo semestre de Pedagogía de las Ciencias Experimentales Química y Biología, periodo mayo- octubre 2020

The research was developed due to the need to consolidate the learning of acids and bases because the research problem was based on not being able to access the laboratories in person, due to the difficult accessibility to the reagents and the high costs prevent proper development of planned experimental themes, the objective was: to determine the use of Natural Indicators as resources for learning acids and bases, the methodology was based on a non-experimental design, the variables were not manipulated, the type of research was field and bibliographic, designan an experimental guide for the learning of acids and bases that was considered as a proposal for third-semester students. For data collection, the survey technique was used with its instrument, the questionnaire that consisted of 10 multiple-choice questions using the Likert scale, carried out with the Word application; the population was 41 students. The results obtained reflected that 80% fully agree on the importance of natural indicators for the determination of acidic and basic substances for daily use. It was concluded that the Natural Indicators as resources for the learning of acids and bases, allowed to determine and consolidate a significant knowledge by linking the acid-base theory with the experimentation in the elaboration of indicators with the students of the second semester of Pedagogy of Experimental Sciences Chemistry and Biology, period May-October 2020.
