At a primary school in a middle-class neighborhood of Caracas, Venezuela, the students' parents play an outsize role.
Gasoline shortages have collapsed public transportation, making it hard for teachers to get to work. Others skip class to scrounge for food and medicine, both of which are in short supply in Venezuela. Due to low salaries, some teachers have quit.
That's why Karen Benini, the mother of a sixth-grader, often steps in to substitute even though she lacks a teacher's certificate.
