New astronomy education project proposes the development of an astronomical virtual reality (VR) platform to enhance astronomy instruction and research, with modules designed to engage students in real-world scenarios and improve problem-solving skills. The VR platform will include specific modules like Virtual Night Sky, Eclipses, Tides, and Parallax, which will be tested for their effectiveness in enhancing student understanding. https://www.stemin3d.net
