¿A qué se refiere "peer" en este contexto?
Let’s turn instead to the evidence that is mounting in our homes, our classrooms and our ball fields. At my kitchen table, putting in a second shift of homework after seven hours in school does not help my son become a more inquisitive, confident, life-long learner with an intrinsic sense of curiosity and joy in discovery. It does not allow my family to strike a graceful balance between school and home life. It does not leave time for those non-academic pursuits — lying on a blanket under the sky and puzzling out the constellations, PEERING UNDER ROCKS, putting a nose in a book for long, lost hours — that can shape a child’s personality, aspirations and dreams.
Lo que encuentro es mirar debajo de las rocas y se me hace raro, ¿a qué tipo de actividad de padres con hijos se refiere?
Gracias
