"Materialízate" is an educational podcast created as part of an Educational Innovation Project at the University of Valladolid. This initiative, integrated into a second-year elective course in the Physics degree program, aims to teach what students are interested in learning through engaging and accessible content. The project actively involves students in their own learning process, while simultaneously disseminating scientific knowledge beyond the university environment.

One of the most common issues in classrooms is the lack of student motivation, often reflected in poor attendance and engagement. "Materialízate" addresses this by giving students a voice, exploring what they want to learn, how they want to learn it, and what motivates them to attend class. The podcast transforms students' questions into engaging episodes, a strategy that has proven successful over two consecutive academic years, with positive feedback from participants.

This project aligns with recommendations from the European Higher Education Area (EHEA), which promotes student-centered active learning supported by flexible curricula and modern technologies. Universities such as Harvard, Oxford, Cambridge, and several Spanish institutions (Alicante, Granada, and Valladolid) have successfully adopted podcasting as an educational tool.

The methodology follows a structured process. Students propose topics related to materials science that pique their curiosity, such as materials used in medical prosthetics or bulletproof vests. The most compelling ideas are selected for podcast episodes, ensuring variety and freshness. Information is gathered from both online resources and indexed scientific journals (JCR). The content is then simplified into accessible language while maintaining scientific rigor. Episodes are recorded in the classroom with students as the live audience. This dynamic setting enhances authenticity, incorporating natural reactions such as laughter and applause. High-quality audio equipment (Rode NT-USB+ microphone and Audacity software) ensures excellent sound production. The recorded content is edited to include background music, sound effects, and a distinctive introduction created in collaboration with a music group. Visual elements like a podcast logo and episode illustrations were designed using Stable Diffusion's AI tools. Episodes are published on streaming platforms such as iVoox and Spotify, with additional promotion through the Instagram account @Materializate_podcast. Listeners can access key references, expanding their understanding of the content.

Student participation is incentivized with extra credit, and evaluations reflect the podcast's positive impact: students rated the podcast 9.5/10 overall, reported increased motivation (8.7/10), improved teacher-student connection (9.1/10), and enhanced learning (9.2/10). Attendance also increased by approximately 30%.

The "Materialízate" project has demonstrated its potential as a scalable and effective educational strategy that can be adapted to various academic levels and disciplines, enriching both student engagement and learning outcomes.
