A weighted lottery is the simplest way for schools to ensure that they enroll a diverse student body while still relying on choice-based enrollment.

ndividual success stories and a review of research suggest that it is possible, by offering all students a single challenging curriculum, to reduce the achievement gap without harming the highest achievers (Burris, Wiley, Welner, & Murphy, 2008; Rui, 2009).

In the middle grades, students at City Neighbors start their day with half an hour of highly specialized, small-group instruction called intensive. Intensive provides an opportunity for extra support or enrichment in different subjects, allowing teachers to meet different students' needs while still teaching most of the academic time in mixed-ability classrooms.

small but growing number of schools are attempting to boost the achievement of low-income students by shifting enrollment to place more low-income students in mixed-income schools. Socioeconomic integration is an effective way to tap into the academic benefits of having high-achieving peers, an engaged community of parents, and high-quality teachers.

A 2010 meta-analysis found that students of all socioeconomic statuses, races, ethnicities, and grade levels were likely to have higher mathematics performance if they attended socioeconomically and racially integrated schools (Mickelson & Bottia, 2010).

Research supporting socioeconomic integration goes back to the famous Coleman Report, which found that the strongest school-related predictor of student achievement was the socioeconomic composition of the student body (Coleman et al., 1966).

nd results of the 2011 National Assessment of Educational Progress in mathematics show steady increases in low-income 4th graders' average scores as the percentage of poor students in their school decreases (U.S. Department of Education, 2011).

a number of studies have found that the relationship between student outcomes and the socioeconomic composition of schools is strong even after controlling for some of these factors, using more nuanced measures of socioeconomic status, or comparing outcomes for students randomly assigned to schools (Reid, 2012; Schwartz, 2012).

Rumberger and Palardy (2005) found that the socioeconomic composition of the school was as strong a predictor of student outcomes as students' own socioeconomic status.

Socioeconomic integration is a win-win situation: Low-income students' performance rises; all students receive the cognitive benefits of a diverse learning environment (Antonio et al., 2004; Phillips, Rodosky, Muñoz, & Larsen, 2009); and middle-class students' performance seems to be unaffected up to a certain level of integration.

A recent meta-analysis found "growing but still inconclusive evidence" that the achievement of more advantaged students was not harmed by desegregation policies (Harris, 2008, p. 563).

he findings suggested that, more than a precise threshold, what mattered in these schools was maintaining a critical mass of middle-class families, which promoted a culture of high expectations, safety, and community support.

istricts have chosen to let school boundaries reflect or even amplify residential segregation.

Have young folk practice rapid retrieval skills alongside quiet time, personal insight, attention to detail, memory. Develop the skills to function well both unplugged and plugged-in.”

“There will be a premium on the skill of maintaining presence, of mindfulness, of awareness in the face of persistent and pervasive tool extensions and incursions into our lives. Is this my intention, or is the tool inciting me to feel and think this way? That question, more than multitasking or brain atrophy due to accessing collective intelligence via the internet, will be the challenge of the future.”

research shows that less teaching plus more feedback is the key to achieving greater learning.

Even if feedback is specific and accurate in the eyes of experts or bystanders, it is not of much value if the user cannot understand it or is overwhelmed by it.

Adjusting our performance depends on not only receiving feedback but also having opportunities to use it.

Clearly, performers can only adjust their performance successfully if the information fed back to them is stable, accurate, and trustworthy. In education, that means teachers have to be on the same page about what high-quality work is. Teachers need to look at student work together, becoming more consistent over time and formalizing their judgments in highly descriptive rubrics supported by anchor products and performances.

Score student work in the fall and winter against spring standards, use more pre-and post-assessments to measure progress toward these standards, and do the item analysis to note what each student needs to work on for better future performance.

Effective supervisors and coaches work hard to carefully observe and comment on what they observed, based on a clear statement of goals. That's why I always ask when visiting a class, "What would you like me to look for and perhaps count?"

. Less teaching, more feedback. Less feedback that comes only from you, and more tangible feedback designed into the performance itself.

play is fundamental to science

When I ask him later why he chooses to teach the way he does, he answers simply, “I think this is a cool way of working, and more people should work this way. Sadly, not everyone does, so I try to pass it on.”

Effective PLCs must focus on student learning. It's no use becoming bogged down in issues or procedures that are out of our control as classroom teachers.

To keep ourselves on track, we examine our students' strengths and weaknesses, creating plans that maximize student success.
