1. Concentration and working memory
Studies from the OECD and Stanford University show that heavy classroom screen use shortens attention spans and weakens working memory. When children learn without digital interruption, they process ideas more deeply and sustain focus for longer periods.
2. Handwriting strengthens learning
A 2020 Norwegian University study using EEG imaging found that handwriting activates broader neural pathways than typing, improving comprehension and recall. Writing by hand helps pupils retain knowledge and develop structured, original thinking.
3. Literacy and cognitive development
OECD data reveal that pupils in high-tech classrooms often perform worse in reading and problem-solving than those in traditional settings. Overexposure to screens can displace reading, conversation, and imagination — all vital for intellectual growth.
