In recent years, it has become common for us to take very seriously the early development of children. But this concern sometimes turns into its opposite. In preschool age, it is important to develop the child’s abilities, and not to provide him with knowledge that he will have time to acquire later. It is not the stock of knowledge, but the ability to acquire and use it that determines the success of schooling and all subsequent human activities. Book by L.A. Wenger, one of the leading Russian psychologists, under whose leadership the “Development” and “Gifted Child” preschool education programs were developed, is a fascinating story about how to develop children’s thinking, intelligence, memory, attention, and imagination. The book is addressed to parents and teachers working with preschool children, students of pedagogical universities and colleges.
