[Türkçe] %85 Kuralı

# The 85% Rule: Why Getting Everything Right (Or Wrong) Kills Learning [Turkish content summary] Cognitive psychologist Robert Björk discovered that learning is optimized at 85% accuracy. Too easy (95% correct) and the brain ignores it as unimportant. Too hard (70% correct) and frustration kills engagement. At 85%, the brain experiences "desirable difficulty" — challenging but achievable. Research shows material learned at 85% accuracy is retained 50-70% longer than material learned at 95%. Amal's HLR adaptive system constantly monitors accuracy and adjusts difficulty to keep each child in the optimal 85% learning zone.
