Find out how a unique AfL strategy inspires students in biology Former bio-medical researcher Anita Kapila is now a brilliant biology teacher. In this programme she demonstrates her AfL strategy. Burnham Upper School, where she teaches, uses an assessment model called The Level Ladder. It allows the children not only to know what level they are currently at, but how they can progress to a higher level. Anita makes sure that the system works well; the students are enthusiastically engaged in the assessment of their learning.
