Resumen
ICT technologies are an integral part of today?s digitized society. Therefore, it is important that children acquire ICT skills as part of 21st century skills education to prepare them for later life. Drawing on the literature, seven 21st century skills can profit from the addition of ICT skills, i.e., technical, information, communication, collaboration, critical thinking, creative, and problem-solving skills. While many efforts have been made to integrate ICT skills as part of 21st century skills education into primary and secondary school curricula, the implementation of these skills in early childhood education and care remains a challenge due to developmental concerns. This paper aims to uncover developmental antecedents for ICT 21st century skills in early childhood, mainly addressing children?s cognitive development, and propose ways to implement these skills in child-friendly ways. Drawing on the literature on developmental psychology, seven cognitive developmental antecedents were identified: inductive, deductive, abductive, causal, and scientific reasoning, executive functions, and computational thinking. Moreover, five additional developmental antecedents were identified: fine motor skills, language development, self-regulation, social-emotional development, and creativity. On the backdrop of these antecedents, ways of implementing ICT skills as part of 21st century skills education in early childhood classrooms are proposed that include digital games and learning apps, collaborative play or problem-solving activities with toy robots.
