ABSTRACT: This paper analyzes the contribution to the conceptualization in the experimental activity in physics, of a theoretical methodological proposal implemented with students of the Biological Physics III course of the Bachelor of Basic Education with emphasis in Natural Sciences and Environmental Education of the University of Antioquia , Colombia. The proposal is based on the Vergnaud Concept Field Theory (1990) and is based on the use of data acquisition systems. The research uses a methodology with a qualitative approach using the instrumental case study as a method. The collection of information is carried out through different instruments such as open questionnaire, participant observation, field diary and semi-structured interview. For the analysis of the information, the processes of transcription, categorization and codification of the data were developed, and at the same time, the triangulation was carried out, as a validity process, between the theory, the instruments and the researchers. Finally, the results are evidenced where the conceptualization of the students who made it possible to achieve this objective was favored.
