In episode 5, our attention shifts away from the ‘macro’ to focus more on the ‘micro’. In a double-length interview with Stephen Heppell, a world expert in online education and learning spaces, we explore how classrooms themselves can become more environmentally-positive spaces. He shows how small environmental changes can have a big impact on the learning experience and learning outcomes – and why every child should bring their own plant to school. From the Field takes us to Palestine, where we see how different approaches to language education – in the case the Hands-Up Project’s innovative use of drama and remote teaching – can empower young people to learn more about the climate crisis whilst also developing their English skills. In The Green Glossary, we examine one of the most common climate-related compounds in English, ‘Carbon footprint’, as well as many other collocations of the word.
