Sumergidos con Arquímedes: actividad tecnológica escolar para la comprensión del principio de Arquímedes, para estudiantes de educación media de la institución educativa distrital Orlando Fals borda

Abstract

The present thesis work consists of presenting the design, validation, and implementation of a school technological activity titled “Submerged with Archimedes” which was implemented with 53 eleventh – grade students from IED Orlando Fals Borda in the city of Bogotá D.C., distributed in three groups (11A, 11B y 11C), in order to evaluate its impact on the understanding of Archimedes principle. For the design of the School Technological Activity, the structure proposed by Quintana (2015a) is followed. For validation an instrument was developed which consists of two components, the first called pedagogical and didactic and the second communicative. Using this instrument, expert peers gave their judgment, and the results were analyzed using the Aiken V index. To measure the impact on the understanding of Archimedes principle among students, pretests/posttests were applied, and the results were processed using Hake’s gain calculation. A normality test was applied for each group, and based on the results, a t-test or Wilcoxon hypothesis test was conducted. Additionally, two activities of the ATE were analyzed, and through transcription, a traceability in the gain in the understanding of Archimedes principle was observed.
