This article explores the extent students’ environmental values are informed through a socioecological learning framework when a deep-time universe hi/story is integrated with environmental education and local cultural origins in the primary school curriculum. The research concept grew from teacher observations that students addressed sustainability from a fragmented action approach, rather than incorporating a lifelong learning and wider worldview of past, present and possible future environmental changes. The research was conducted with 8–9-year-old students during a 17-week transdisciplinary pedagogical intervention, adapted for primary-aged students, from an educational evidence-based, online Big History Project, empowering young learners to engage in transformative thinking and to add their voices as co-researchers. Additional data was collected from the same co-researcher and student cohort two years later. The research findings over the two years remain significant, where students continued to discuss the environment and sustainability in the context of a child-framed deep learning pedagogy framework of the changing 13.8-billion-year universe story. If this original research is to remain significant, further research and programming need to be undertaken with students and educators, to ensure that the value of deep-time hi/story is embedded at all levels of the education continuum, including primary-aged students.
