The Impact of the Usage of Hypercultural Mediation in the Teaching of Special Relativity in High School in Brazil

Maira Giovana de Souza, Agostinho Serrano


Background: Given the importance of working on Modern Physics in the classroom and considering the great difficulty of understanding by students, it is important to investigate efficient ways to develop the theme. Objective: Identify if there was learning after using a didactic material built using animated gifs and specially after using computer simulations, and to investigate if there is a difference in learning between students who interacted and did not interact with the computer simulations. Design: The design is based on a quantitative analysis made by comparing the results of pre-tests and post-tests of the control and experimental groups. Setting and participants: The research was carried out with 82 students from the third year of high school from a public school. Of these students, 62 form the experimental group, while 20 make up the control group. Data collection and analysis: The activities were developed during the curricular classes of the Physics discipline, with the application of questionnaires immediately before and after the activities. The activities contemplated the four types of mediations (according the CNMT referential), and the control group did not use hypercultural mediation. Results: The outcome of the analysis shows a significant difference in the results of the control and experimental groups, and the experimental group showed a statistically superior growth. Conclusions: Using the four types of mediations, especially hypercultural, students' learning is enhanced for Special Relativity concepts and problem-solving.
