In today’s complex world, a continuous upgrade of knowledge is crucial. Digital literacy, as one of the key competencies of the 21st century, is becoming more critical since it enables an efficient use of digital devices and tools. The European Union has set five key competencies for digital literacy, including informational and data literacy, digital content creation and communication and collaboration. In education, communication is widely accepted as a crucial skill for achieving common goals. Collaborative learning has proven to be a practical approach to teaching since it encourages the active participation of learners, provides many valuable and innovative solutions, and enables the development of key competencies. The collaborative workability can be further enhanced through cross-curricular integration, where learners are taught independent learning, information-seeking skills and critical thinking. In the school context, combining digital competencies, collaborative learning, and cross-curricular integration is key to preparing students for life in the modern world. This research presents an example of developing digital competencies in technology engineering lessons. The example above is offered in three stages and covers a period of ten school lessons. In addition to digital competencies, students are developing other competencies that will benefit their daily lives. Research is aimed at teachers who want to build digital competencies in their students through experiential learning, collaborative work, and cross-curricular integration, as well as prepare them for future challenges.
