The two-volume set LNCS 15159 and 15160 constitutes the proceedings of 19th European Conference on Technology Enhanced Learning, EC-TEL 2024, which took place in Krems, Austria, in September 2024. The 37 full papers, 25 poster papers, and 10 demo papers presented in the proceedings were carefully reviewed and selected from 140 submissions for research papers, and 26 poster and 19 demo submissions. They focus on effective technology adoption in educational settings, ethical concerns, and the possible digital divide these technologies could create. The theme for the 2024 conference aimed to explore the role of Technology-Enhanced Learning (TEL) in this critical context and in achieving the United Nations' Sustainable Development Goal for education: "Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.".
