The teacher prep period time is up. The bell rang and the students started coming into the classroom. The 50 minutes of preparation were spent calling parents who had not followed up on their children’s performance in school and completing referrals to the social worker. Those 50 minutes are the time teachers have available each day, in theory, to organize their class material, upload information about their students to the Department of Education’s (DE) digital archives, or get other tasks done. But the educator — who prefers not to identify herself — teaches five groups; at least 125 students in total.
