In engineering education, one of the challenges lies in helping students understand complex technical systems in a more visual and accessible way. In this context, a 360º visualization experience focused on an engine was implemented as a teaching innovation, allowing students to explore the resource on a computer screen. Specifically, the aim of the present study was to analyse students’ post-experience perceptions of the utility, novelty and relevance of this educational resource and to examine the pedagogical value attributed to it in comparison with the usual course resources. A second aim was to compare this pattern in two universities in which the experience was implemented in the same way: the University of Cádiz (Spain) and Tecnológico de Monterrey (Mexico). To this end, 40 post-experience questionnaires were analysed, corresponding to 20 students from each university. The instrument included three items assessing the perceived utility, novelty and relevance of the technological resource, using a seven-point Likert scale, together with an open-ended question aimed at capturing students’ qualitative perceptions of the experience and its added value compared with the usual course resources. Results indicate a clearly positive evaluation in the three dimensions considered. In both institutions, the resource was assessed very favourably, suggesting that it was perceived not merely as an attractive addition, but as a meaningful support for learning. This interpretation was reinforced by the qualitative responses, which highlighted the role of the experience in making the engine easier to visualise and understand, as well as more engaging from an educational perspective. Although students from Tecnológico de Monterrey tended to provide slightly higher scores, no statistically significant differences were found between the two universities. Overall, the findings suggest that 360º visualization constitutes a valuable educational innovation in engineering teaching across two academic contexts. In particular, students attributed to it a pedagogical value that went beyond the usual course resources. The contribution is therefore centred on students’ appraisal of the resource after use. It focuses on the value they attribute to it within the teaching process, rather than on the measurement of learning outcomes. The study may be of interest to teachers and researchers involved in the design and assessment of digital educational innovations in higher education, especially in disciplines dealing with complex technical contents.

Pre-post preliminary evidence of improved conceptual understanding of an engine through a 360° virtual environment Ruiz Marín, Nazaret; Pérez García, Santiago Leonel; Rojas, Juan-Carlos; Higuera Trujillo, Juan Luis The teaching of engine-related contents in engineering programmes often requires students to understand spatial, functional and thermodynamic relations that may be difficult to grasp through lectures and conventional teaching materials alone. In this context, visual digital resources may help students approach such contents in a more intuitive and understandable way. Specifically, the aim of the present study was to examine whether the use of a 360º virtual environment was associated with objectively measured changes in students’ conceptual understanding of the engine, implemented identically at the University of Cádiz (Spain) and Tecnológico de Monterrey (Mexico). The focus was therefore placed on objective pre-post learning performance rather than on students’ post-experience evaluation of the resource. To tackle it, three objective learning questions were administered before and after the activity, and a total learning score was calculated from the number of correct answers obtained in each questionnaire. In total, 40 pre-experience and 40 post-experience questionnaires were analysed, evenly distributed between Cádiz and Monterrey (20 in each group). Results indicate that learning scores were significantly higher after the experience than before it when the total sample was considered. This same pattern was observed when each university was analysed separately, with significant differences between the pre- and post-experience measurements in both cases. By contrast, no statistically significant differences were found between the two universities either before or after the activity. As a whole, the findings suggest that this educational innovation may contribute to improving students’ short-term conceptual understanding of the engine, showing a consistent pre-post pattern across two different institutional contexts. The contribution is therefore centred on objective evidence of conceptual learning, rather than on students’ perceptions of the pedagogical value of the resource. These preliminary results may be of interest to teachers and researchers working on technology-enhanced learning, engineering education, and the teaching of contents that are difficult to communicate through traditional resources alone.

LIFE 02 / NAT / E / 8610. La investigación pone de manifiesto la repercusión que la contaminación acústica debida al denso tráfico marítimo del Estrecho de Gibraltar, tiene sobre el comportamiento de las poblaciones de delfines mulares que están asentadas en aquella zona. El estudio crea una base de datos de ruido emitido a distintos regímenes por los buques que frecuentan el Estrecho y sus rutas. Por otro lado, investiga en qué medida los cetáceos se han adaptado en relación a sus patrones espaciales de alimentación y esquemas de comunicación. Este trabajo inicia una línea de investigación dentro de la acústica submarina durante los años 2000 al 2006. Este trabajo es reflejo del proyecto: “Identificación de las posibles acciones de los Fast-Ferries, que podrían provocar un impacto negativo sobre las poblaciones de cetáceos”. Código: PN1997 de plan nacional I+D, Ministerio de Ciencia y Tecnología. Y que más adelante desembocaron en una línea de trabajo a largo plazo con el proyecto europeo LIFE que se inicia en el 2002: Acción D.10ª.3: “Conservación de las poblaciones delfín mular, marsopa y tortuga boba, y sus hábitats en Murcia y Andalucía. Aplicación de la Directiva hábitat”: ACCIÓN D.10.A.3.: Contaminación acústica: Efectos en las poblaciones de delfín mular y marsopa y en sus hábitats; del Proyecto LIFE –NATURALEZA: LIFE02 NAT/E/8610.

Dicha zona comprende cuatro municipios que en conjunto pueden ser tratados como una aglomeración en relación a los criterios de la Directiva Europea 2002/49/EC. Lo que se constata es que con el desarrollo legislativo en cuanto a protección ambiental contra el ruido, los niveles máximos de ruido han disminuido. Sin embargo, y al mismo tiempo, ha habido un aumento progresivo de población expuesta niveles de ruido que podíamos definir como medios. Dado el contexto en el que se desarrolla el trabajo y los resultados obtenidos en este trabajo, se promueve por parte de Servicio de Prevención Ambiental de la Consejería de Medio Ambiente (J.A.) incluir estos estudios en el Plan para el Control de la Calidad ambiental en el campo de Gibraltar 2003-2005, ello se concreta en el Proyecto denominado: “Análisis de la contaminación Acústica en el área del Campo de Gibraltar Plan General de Calidad Ambiental del Campo de Gibraltar”; ref. OT2005/190, desarrollado entre el 2003 y el 2005.
