Wales and Finland teacher exchange ahead of Pisa results
Wales is hoping for a better result when the global league tables for education are published next Tuesday.
The Organisation for Economic Co-operation and Development's programme for international student assessment (Pisa) results come round every three years and this time the focus will be on mathematics.
Wales lagged behind most other countries, coming 40th in maths in 2009.
Finland has consistently performed well, so BBC Radio Wales sent Chris Parry, head of maths at Ysgol Friars in Bangor, to Hameenkylan school in Vantaa, Helsinki, to learn from the Scandinavian country's success.
