Engel’s research paints an even bleaker picture of our education systems. Toddlers may ask up to twenty-six questions per hour at home (with one child asking 145 during one observation!) but this drops to just two per hour at school. This disengagement can also be seen in other expressions of curiosity – such as how willing they are to explore new toys or interesting objects – and it becomes even more pronounced as the child ages. While observing some fifth-grade lessons, Engel would often go for a two-hour stretch without seeing a single expression of active interest.
