Kicking off ‘Computer Science for All,’ city will add AP classes, software programs

New York City’s plan to provide a computer science education to its 1.1 million students will kick off next year in at least 50 schools, which will offer an Advanced Placement-level class or a software engineering program for the first time.

Starting this month, schools can apply to offer the “The Beauty and Joy of Computing,” a one-year course for high schoolers, or a multi-year software engineering program. The programs, which already exist in a few anozen schools across the city, represent the first steps in a larger plan that officials say they will be working on for at least a year.

“This is the first step to build on what we’ve already done,” Debbie Marcus, the education department’s executive director of computer science, said this week.

Mayor Bill de Blasio announced his plan to provide computer science in every school by 2025 in an agenda-setting speech last September. To get there, the city will have to find ways to train hundreds of teachers at all grade levels, help schools develop and choose programs and teaching materials, and overcome barriers to securing Internet access and computers.

The city’s first steps will target schools with leaders who say they’re already prepared to meet those challenges.

Applications for both programs ask schools to explain the technology classes they already offer and the experience levels of the prospective instructors. Schools offering the AP program will be expected to do targeted outreach to girls and other underrepresented student groups, the application indicates.

Marcus said the city also wants to make sure the programs reach a broad spectrum of students, and that all schools — from the most struggling to its sought-after specialized schools — will be considered.

As for the two programs the city is focusing on, each represents a different approach to computer science education.

“The Beauty and Joy of Computing” is a one-year course designed to teach the principles in computer science in high schools. Though it’s an advanced course originally created for college freshmen, the curriculum is designed to be accessible to a broad range of students, said Dan Garcia, a teaching professor at UC Berkeley who co-designed the class. Students who take the course should be prepared for a new AP exam being rolled out in 2017.

If the traditional Advanced Placement Computer Science curriculum is like calculus, Garcia said, then “Beauty and Joy” could be compared to pre-calculus.

The city’s Software Engineering Program is more than just one class. It’s a structured sequence of electives for middle and high school students designed to provide a background in programming, robotics, web design, physical computing, and mobile computing. The program launched in 2013 under former Mayor Michael Bloomberg and is now in 18 schools.

Of course, to reach over 1,800 schools, the city will need to do more than expand these existing programs, and find ways to reach younger children Officials said that these are not the only programs that they will unveil next year and that more information will be released this spring. In the meantime, they are working on a “foundational document” that outlines the city’s plans for expanding the program throughout the city.

Marcus said the document could take up to a year and a half to complete, as the city looks at model programs from across the country and consults expert teachers, researchers, and programmers.

“One of the reasons it’s a 10-year initiative is it’s not going to happen overnight,” she said. “Not all programs require this level of commitment on the part of teachers and schools. Software engineering is really in-depth — we’re also looking at lower levels of commitment for teachers to understand a specific concept or tool.”

Marcus said the city plans to focus on training teachers in a variety of subjects to teach computer science, instead of recruiting new teachers who specialized in the subject.

That raises a red flag for Maurya Couvares, the co-founder and executive director of ScriptEd, which helps teenagers land technology internships. She said that it will be difficult for classroom teachers to learn the skills necessary to teach a full computer science course without significant professional development.

“I’m interested to see how they will do this,” Couvares said. “Hopefully that they won’t deliver a watered-down version to students.”

Garcia, for one, said his course’s training is anything but. The “Beauty and Joy” training includes two weeks of in-person work and a two-to-four-week online course during the summer.

“This is not at all a lightweight, one-week situation,” Garcia said. “This is a very powerful, deep course.”

Signal Mountain leaders look to Shelby County as model for school district secession

A cluster of towns that broke off from Shelby County Schools to create their own school systems in 2014 is about to host visitors from another Tennessee town looking into the viability of leaving Hamilton County Schools.

A committee from Signal Mountain, on the outskirts of Chattanooga, is scheduled next week to visit with leaders from Arlington, Bartlett, Collierville, Millington and Germantown. Along with Lakeland, the six towns have just completed a third year of operating their own school systems, just outside of Memphis.

Signal Mountain is in its second year of discussions about a possible pullout from the Chattanooga-based district. The community has three of Hamilton County’s higher-performing schools, as well as fewer poor and minority students. Its Town Council created the committee in January to look into the feasibility of creating a separate district, which would siphon off both students and revenue from Hamilton County Schools.

As part of their visit, the seven-member panel will hold open meetings with municipality leaders at Arlington High School. Signal Mountain Mayor Chris Howley and Councilwoman Amy Speek are scheduled to join the sessions.

“We felt it was valuable for us to meet with board members and school officials to gain insight on how the process went, what they learned, what they might do differently,” said committee chairman John Friedl.

“We’re not trying to reinvent the wheel,” he added.

The visit will come days after Shelby County’s secessions were spotlighted in a national report on the trend of wealthier and whiter communities to splinter off from larger school systems that are poorer and more diverse. The report was crafted by EdBuild, a nonprofit research group that focuses on school funding and equity. The report also listed Signal Mountain among nine towns across the nation that are actively pursuing pullouts.

The town of Red Bank, which is just east of Signal Mountain, also recently announced it will investigate launching a separate district.

If Signal Mountain residents vote eventually to create their own school system, they would use the same Tennessee law that allowed municipality voters in Shelby County to exit Tennessee’s largest district. The law, which EdBuild calls one of the most permissive in the nation, allows a town with at least 1,500 students to pull out without the approval of the district it leaves behind or consideration of the impact on racial or socioeconomic equity.

Signal Mountain leaders will focus next week on lessons learned by leaders in Shelby County.

After breaking off in 2014, the municipalities gained about 30,000 students, 33 schools and all of the challenges that come with launching new school systems. That includes funding, staffing and facilities. “We all started out with a central office staff of one, … and we had to build from there,” Millington Municipal Schools Director David Roper said during a 2015 presentation to state lawmakers.

The Shelby County breakaway also ended up in court over charges that the exit was racially motivated. But a federal judge eventually dismissed that lawsuit by Shelby County Schools.

The Signal Mountain exploration also has been met with some community resistance. A group called Stay with HCSD is advocating staying with Hamilton County Schools.

Growth plus proficiency? Why states are turning to a hybrid strategy for judging schools (and why some experts say they shouldn’t)

A compromise in a long-running debate over how to evaluate schools is gaining traction as states rewrite their accountability systems. But experts say it could come with familiar drawbacks — especially in fairly accounting for the challenges poor students face.

Under No Child Left Behind, schools were judged by the share of students deemed proficient in math and reading. The new federal education law, ESSA, gives states new flexibility to consider students’ academic growth, too.

This is an approach that some advocates and researchers have long pushed for, saying that is a better way to judge schools that serve students who start far below proficiency.

But some states are proposing measuring academic growth through a hybrid approach that combines both growth and proficiency. (That’s in addition to using proficiency metrics where they are required.) A Chalkbeat review of ESSA plans found that a number of places plan to use a hybrid metric to help decide which of their schools are struggling the most, including Arizona, Connecticut, Delaware, Louisiana, Massachusetts, and Washington D.C.

The idea has a high-profile supporter: The Education Trust, a civil rights and education group now headed by former U.S. Education Secretary John King. But a number of researchers say the approach risks unfairly penalizing high-poverty schools and maintaining some of the widely perceived flaws of No Child Left Behind.

These questions have emerged because ESSA, the new federal education law, requires states to use academic and other measures to identify 5 percent of their schools as struggling. States have the option to include “academic progress” in their accountability systems, and many are doing so.

This is a welcome trend, says Andrew Ho of Harvard, who has written a book on the different ways to measure student progress. Systems that use proficiency percentages alone, rather than accounting for growth, “are a disaster both for measurement and for usefulness,” Ho said. “They are extremely coarse and dangerously misleading.”

Under a growth-to-proficiency model, Student A would be considered on track to proficiency by grade 6 based on the growth from grades 3 to 4, but students B and C would not. (Image: Ho’s “A Practitioner’s Guide to Growth Models”)

States that propose using this hybrid measure — commonly called “growth to proficiency” or “growth to standard” — have offered varying degrees of specificity in their plans about how they will calculate it. The basic idea is to measure whether students will meet or maintain proficiency within a set period of time, assuming they continue to grow at the same rate. Schools are credited for students deemed on track to meet the standard in the not-too-distant future, even if the students aren’t there yet.

This tends to rewards schools that serve students who are already near, at, or above the proficiency standard, meaning that schools with a large number of students in poverty will likely get lower scores on average.

It also worries researchers wary of re-creating systems that incentivize schools to focus on students near the proficiency bar, as opposed to those far below or above it. That phenomenon has been observed in some research on accountability systems focused on proficiency.

“As an accountability metric, growth-to-proficiency is a terrible idea for the same reason that achievement-level metrics are a bad idea — it is just about poverty,” said Cory Koedel, an economist at the University of Missouri who has studied school accountability. He has argued that policymakers should try to ensure ratings are not correlated with measures of poverty.

Researchers tend to say that the strongest basis for sorting out the best and worst schools (at least as measured by test scores) is to rely on sophisticated value-added calculations. Those models control for where students start, as well as demographic factors like poverty.

“If there are going to be high stakes — and I don’t suggest that there should be — then the more technically rigorous value-added models become the best way to approach teacher- and school-level accountability,” said Ho.

A large share of states are planning to use a value-added measure or similar approach as part of their accountability systems, in several cases alongside the growth-to-proficiency measure.

Some research has found that these complex statistical models can be an accurate gauge of how teachers and schools affect students’ test scores, though it remains the subject of significant academic debate.

But The Education Trust, which has long backed test-based accountability, is skeptical of these growth models, saying that they water down expectations for disadvantaged students and don’t measure whether students will eventually reach proficiency.

“Comparisons to peers won’t reveal whether that student will one day meet grade-level standards,” the group’s Midwest chapter stated in a report on Michigan’s ESSA state plan. “This risks setting lower expectations for students of color and low-income students, and does not incentivize schools to accelerate learning for historically underserved student groups.”

In an email Natasha Ushomirsky, EdTrust’s policy director, said the group supports measures like growth to proficiency over value-added models “because a) they do a better job of communicating expectations for raising student achievement, and b) they can be used to understand whether schools are accelerating learning for historically underserved students, and prompt them to do so.”

Of the value-added approach, Ushomirsky said, “A lower-scoring student is likely to be compared only to other lower-scoring students, while a higher-scoring student is compared to other higher-scoring students. This means that the same … score may represent very different amounts of progress for these two students.”

Marty West, a professor at Harvard, says the most prudent approach is to report proficiency data transparently, but to use value-added growth to identify struggling schools for accountability purposes.

“There are just too many unintended consequences from using [proficiency] or any hybrid approach as the basis of your performance evaluation system,” he said.

“The most obvious is making educators less interested in teaching in [high-poverty] schools because they know they have an uphill battle with respect to any accountability rating — and that’s the last thing we want.”
