In Greg Hawkins' sixth-grade math class, students attempt to solve multi-step problems, despite stumbling over words like "approximately."
Over in Leif Neilson's math class, anxious eighth-graders are urged to read practice questions carefully before picking an answer.
Downstairs, language arts teacher Sarah Salo pleads with her sixth-graders to stay the course, even if they don't care much for reading about lumberjacks.
As this year's round of state assessments starts this week, nowhere are the stakes greater than at Nellie Stone Johnson Elementary in Minneapolis, which has had among the worst test scores in Minnesota.
Persistently low test scores earned the school the dubious distinction of being one of only two schools in the state tagged for "restructuring" under the federal No Child Left Behind Law last year. Lucy Craft Laney in Minneapolis was the other.
More than one-third of the state's schools missed their student achievement goals last year. Missed goals mean sanctions for schools that escalate with every year the goal is missed, leading up to the ultimate sanction: restructuring.
Restructuring means the school staff is replaced.
Or, in Minneapolis school district parlance, "fresh-started." Johnson started this school year with a new principal, teaching staff and mindset.
