Interdisciplinary projects can significantly boost student engagement by connecting multiple subjects through relevant and real-world issues. This approach enables learners to see the interconnections in knowledge, fostering deeper understanding and critical thinking. For example, a project that integrates science, history, and art can help students grasp complex themes like environmental change or cultural movements. Moreover, collaboration among teachers from different disciplines promotes a holistic learning environment, encouraging innovation, enhancing motivation, and developing a sense of ownership in their learning process.
