Jharkhand Student Innovates with 5-Kilometer Audio Transmitter Through STEM Initiative
In a remarkable demonstration of practical learning, Khushi Kumari, a Class IX student at Kasturba Gandhi Balika Vidyalaya in Chanho, Ranchi, has successfully developed a long-range audio transmitter capable of covering distances up to 5 kilometers. This innovative device can connect hundreds of users simultaneously, enabling the dissemination of critical information, broadcasting educational content for children in rural areas, and providing various essential communication services.
From Struggling with Science to Creating Solutions
Khushi's journey to this technological achievement is particularly inspiring. She once found science challenging and struggled to grasp textbook concepts. Her transformation began when she gained hands-on experience through activity-based learning at the Science, Technology, Engineering and Mathematics (STEM) laboratory established at her school just one year ago.
"This device can help impart important information to a large number of audiences at one go in remote places, where communication media are very limited," explained Khushi. "I built the device at the STEM lab with the guidance of my science teacher in school."
Transforming Education for Tribal Girls Across Jharkhand
Khushi represents just one success story among thousands. Currently, over 36,000 girl students from tribal and marginalized families across Jharkhand are learning science through practical, hands-on activities that encourage them to find solutions to real-world problems. Students at 82 government-run Kasturba Gandhi Balika Vidyalayas (KGBVs) and Jharkhand Balika Awasiya Vidyalayas (JBAV) are now exploring scientific concepts through practical application rather than traditional rote memorization.
This educational transformation has been made possible through the introduction of activity-based STEM education in these schools, fundamentally changing how science is taught and understood.
Project Bridge: A Collaborative Effort for STEM Advancement
The STEM laboratories have been established in schools across seven districts of Jharkhand under 'Project Bridge', a strategic partnership between the state education department, UNICEF India, and BMW Group. This initiative aims to strengthen STEM education by providing resources, training, and infrastructure to enhance learning outcomes.
Recently, a team from these organizations visited three schools in Ranchi to review the project's progress. Following the visit, Saadhna Panday, UNICEF India's chief of education, noted that while India has made significant progress in foundational learning, this hasn't necessarily translated into strong performance in secondary-level STEM subjects.
"Through this partnership, we are working with state governments to improve participation and transform how these subjects are taught," Panday emphasized.
Encouraging Results and Future Expansion Plans
Vinod Pandey, director of government and external affairs and CSR at BMW Group India, who reviewed the program on the ground, expressed enthusiasm about the initial outcomes. "The initial results were highly encouraging with a clear demonstration of improved conceptual understanding," he stated. "We will continue to focus on enhancing content and pedagogy to drive better student outcomes in STEM subjects."
Shashi Ranjan, director of the Jharkhand Education Project Council (JEPC) under the state education department, revealed ambitious expansion plans following the pilot project's outstanding results. "Jharkhand has around 2,800 secondary-level schools. We are planning to set up STEM labs in all the schools in a phase-wise manner, so that more students, especially girls, can be attracted towards science in higher levels as well," he announced.
This comprehensive approach to STEM education is not only creating innovative solutions like Khushi's audio transmitter but is also building a foundation for future scientific advancement and gender equity in education across Jharkhand.
