Welcome to The Transdisciplinary STEAM+ Journal, a transdisciplinary, global, theory-practice, peer-reviewed, open access, online journal with a focus on arts integration. The Transdisciplinary STEAM+ Journal brings together perspectives, artwork, research, teaching, and practice. We promote arts integration not just with STEM, but also with the Social Sciences and the Humanities. This expansion helps us better explore the connecting complexities of science, social phenomena, human behavior, and experiences of being and becoming through the lens of the Arts. We welcome researchers, artists, educators, field practitioners, and young voices from multiple disciplines and practice spaces within and beyond academia to share work that supports deep learning, social impact, and human flourishing through arts integration. We invite artwork, arts-based social advocacy and activism, arts-based research in Social Sciences, Humanities, and Science, blog post reflections and op-ed articles, reviews of books about STEAM and arts integration, and arts-integration lesson plans.
