Realidad aumentada como herramienta didáctica para el aprendizaje de mecanizado y construcciones metálicas del primer año colegio "demetrio aguilera malta

Abstract

The degree work was carried out at the Colegio de Bachillerato "Dr. Demetrio Aguilera Malta", located in the city of Santa Rosa, belonging to the province of El Oro, with the collaboration of the teacher in charge of the professional figure of Machining and Metal Constructions, as well as the participation of the students of the first year of Bachillerato, section "A", during the academic period 2023-2024. The aim of the research was to establish Augmented Reality as a didactic tool to improve the learning process. We sought to identify the influences of Augmented Reality by designing a prototype adapted to the contents of the subject and analysed its impact on the learning process in relation to academic performance. This led to the creation of "BRAANTH", a virtual world developed in CoSpaces that simulates a workshop and is distinguished by encouraging the participation and interest of students, allowing them to interact with virtual models of metal components and the information necessary to strengthen learning. For the creation of the prototype, the ADDIE methodology was used, which, through its five phases (Analysis, Design, Development, Implementation and Evaluation), provided an instructional design for the construction of the prototype, including initial, procedural and final evaluation stages in the Augmented Reality platform CoSpaces Edu. The effectiveness of the virtual world was confirmed in the results obtained during two experiences carried out with the teacher and students. Firstly, an initial evaluation was carried out through an interview with the teacher, who expressed his satisfaction with the appearance and the implemented contents, resulting in minimal observations. The second experience was carried out with the students of the course through a demonstration class using BRAANTH, in which pre- and post-tests were applied in order to measure their knowledge before and after using the prototype. The results showed that students demonstrated a significantly higher level of learning effectiveness when Augmented Reality was used compared to situations where it was not. In short, based on the perceptions gathered on the implementation of BRAANTH, it is essential to highlight the value of the virtual world as a tool that strengthens the learning process by enabling dynamics, interaction and innovation in the presentation of content.
