Revolutionizing British Sign Language Vocabulary for Science Communication

Spread the love

Deaf scientists and sign language experts have embarked on a groundbreaking endeavor, enriching British Sign Language (BSL) with a plethora of new signs. The expansion of BSL’s lexicon now encompasses climate-related terms, such as “greenhouse gas” and “carbon footprint,” which previously lacked official signs. This linguistic innovation eradicates the need for arduous finger-spelling of intricate scientific terminologies and aims to make scientific concepts more visually accessible.

A Vision for Scientific Clarity

Dr. Audrey Cameron, a profoundly deaf scientist leading the project at Edinburgh University, elucidated the mission: to craft signs that perfectly encapsulate scientific ideas. With her own experience as motivation, Dr. Cameron has spearheaded the addition of 200 new environmental science terms to the BSL dictionary. She recounted her own challenges, expressing how the absence of vocabulary excluded her from critical discussions during her scientific career.

The Power of Visual Language in Science

Liam McMulkin, a biology teacher from Glasgow, has actively contributed to the creation of new signs through workshops hosted by the Scottish Sensory Centre. McMulkin highlighted the efficacy of sign language in conveying complex scientific concepts, particularly due to its visual nature. For instance, he explained how the sign for “photosynthesis” involves a leaf-like hand gesture and sun-ray-like finger projection, beautifully capturing the energy-absorption process.

A Decade-Long Endeavor

The science glossary initiative, funded partially by the Royal Society, commenced in 2007 and has introduced approximately 7,000 new signs to BSL. The latest additions are focused on biodiversity, ecosystems, the physical environment, and pollution, accompanied by an online video glossary showcasing these terms.

Empowering Deaf Students Through Visual Learning

The glossary’s primary objective is to bolster the education of deaf students within mainstream schools. Melissa, a 13-year-old deaf student, emphasized the transformational impact of these signs on her comprehension. With the new signs, intricate concepts like “greenhouse gases” become tangible as she imitates gas molecules with her closed fists.

A Natural Language for Science Education

McMulkin highlighted the importance of sign language in science education for deaf children, as it enables them to learn in their native language. Dr. Cameron further emphasized its value, recalling a class of five-year-olds mastering the concept of density using a sign that involved hand movements. The transformative potential of these signs is evident in their profound impact on comprehension and engagement.

A Catalyst for Inclusivity

Prof. Jeremy Sanders, chair of the Royal Society diversity and inclusion committee, praised the endeavor’s potential to inspire BSL-using students and facilitate scientists’ global communication. This linguistic revolution in science communication demonstrates the potency of inclusive language and visual expression in bridging knowledge gaps.
