How language barriers are impeding science learning

Language plays a crucial role in education, shaping how students learn and connect with the world.

Yet, according to UNESCO, 40 per cent of the global population does not have access to education in a language they speak or understand.

This gap presents a significant barrier to effective learning, particularly in science education, where technical terms and complex concepts are often difficult to understand in unfamiliar languages.

In our first podcast episode of 2025, our reporter, Michael Kaloki, explores the importance of teaching science in local languages in Africa where multiple indigenous languages are spoken.

Adeyemi Ademowo, a Nigerian professor of social anthropology and African cultural studies at Afe Babalola University in Nigeria’s Ekiti state, wants to see children in rural areas taught in their local language.

Grace Kago, a Kenyan post-doctoral fellow in biomedical sciences at the University of Texas, says teaching science in indigenous languages can foster public trust in science and encourage community participation in scientific discussions.

How can multilingual education systems be implemented in countries with numerous languages? Algerian researcher Zehlia Babaci-Wilhite proposes some innovative solutions, including bilingual and multilingual education models.

Please tune in to the episode to find out how she suggests implementing this approach.

This podcast was supported by the Science Granting Councils Initiative which aims to strengthen the institutional capacities of 18 public science funding agencies in Sub-Saharan Africa.
