Modern physics is an exciting and rapidly progressing field, prompting significant shifts in how we teach physics across all educational levels. While there is broad agreement on the need to modernise physics education and support physics teachers in this transition, existing initiatives often remain scattered across different educational contexts. In response, this directions paper synthesises insights from the International Modern Physics & Research in Education Seminar Series symposium to guide the efforts of our global physics education community and to increase their impact and reach. We bring together viewpoints from the symposium's panellists and discuss these views as visions for the future of our field, mapping out pathways for navigating the challenges and opportunities ahead. Ultimately, we hope this paper will serve as a roadmap for teachers, educators, and physicists wishing to enhance modern physics education research and practice.
