Jean Plagets 2nd theory is Pre- operational between ages 2.7 where children learn proper grammar and syntax True False

False.Jean Piaget's second stage of cognitive development is the Preoperational Stage, but it occurs roughly between the ages of 2 and 7, not 2.7. Furthermore, while language development is a key feature of this stage, the development of proper grammar and syntax is an ongoing process that extends beyond the preoperational stage. Children in this stage are still developing their language skills and may make grammatical errors. They are egocentric in their thinking and haven't yet mastered logical reasoning.
