Web Quests are challenge-based, learner-centred activities that encourage students to explore real-world problems through online research, collaboration, critical thinking and the use of digital tools. In the FuturENG project, Web Quests form a core component of the Challenge-Based Learning Toolbox, helping engineering students apply knowledge on topics such as Industry 4.0, the twin transition, sustainable digitalisation and deep technologies, while developing their digital, green and transversal skills. Through these structured activities, students work on authentic challenges, analyse information, propose solutions and collaborate with peers. The FuturENG Web Quests are available on the project’s online platform, where they complement the MOOC and other interactive learning resources.
