Research, published recently by academics from UCL’s Institute of Cognitive Neuroscience, has shown that older teenagers and young adults are able to improve their fundamental maths skills and reasoning abilities more rapidly than younger teens. This research resonates with the approach of Steiner Waldorf schools, who identify these strengths in older teenagers and actively plan their curriculum accordingly. The research also highlights the flaws in testing at age 11 for selective schooling, given that these skills can be significantly improved at a later stage.
