Bootstrap brings coding, math to middle schools Developed in part by Brown faculty, curriculum supports White House’s CS for All initiative By HATTIE XU STAFF WRITER

Ten thousand middle school students in 17 states are now designing video games while solving algebra problems, thanks to Bootstrap, a curriculum developed by Emmanuel Schanzer, Shriram Krishnamurthi, professor of computer science and Kathryn Fisler, adjunct professor of computer science. Initiated in 2006, Bootstrap is used by 250 teachers across the United States and five other countries, Krishnamurthi said. As part of President Obama’s Computer Science for All initiative, the curriculum has received national attention and was featured on the White House blog. “We want to make a significant contribution to the way math is taught in the United States, and we want everyone to be exposed to computer science,” Schanzer said. “We tried to make something light enough so that it feels like exposure, but heavy enough so that it’s a meaningful and memorable first step into computer science.”

Bootstrap helps students learn algebra, a necessary life skill, and introduces computer science to students early enough so they do not rule it out as a career choice without being exposed to it, Krishnamurthi said. “Computing has become a fundamental tool for many different disciplines,” Fisler said. “Some are science disciplines, but some aren’t. Look at how much media is produced digitally and how a lot of artists now need to know about computation.” Since 1985, Krishnamurthi has been interested in computer science outreach and education. Krishnamurthi worked with his adviser at Rice University, Matthias Felleisen, on Program by Design — a curriculum for high school and college students, Krishnamurthi said. As a high school teacher in Boston, Schanzer saw his students struggling with algebra and was inspired to find a new way to teach it, he said. Using the programming language Racket, Schanzer began to develop a curriculum for middle and high school students. In a chance meeting on an MBTA train, Felleisen, creator of Racket, noticed Schanzer using the programming language, Krishnamurthi said. Felleisen connected Schanzer to » See BOOTSTRAP, page 2

The Bears got off to a slow start against Harvard but slowly worked their way back into the match. Despite strong efforts from Justin Staudenmayer ’17 and Steven Galiardo ’17, Bruno eventually fell 25-10.

Bears bounce back after loss to Harvard Younger wrestlers get chance to grow against Roger Williams at Beauty, Beast competition By NIKKO PASANEN SENIOR STAFF WRITER

It was a packed house Sunday at the Pizzitola Sports Center, where over 700 spectators spent their Valentine’s Day at the second annual Beauty and the Beast competition. But the boisterous crowd was not enough to inspire the Bears to a

victory over Ivy League rival Harvard. The day’s second contest against Roger Williams brought better results, giving Bruno a split on the day and the fans something positive to cheer about. “This is our favorite event of the year. Everyone gets really hyped up for it,” said Justin Staudenmayer ’17. “We had a tough match against Harvard — a couple things didn’t go our way — and you can see that on the scoreboard. But overall I thought we fought hard, and then we picked things up against Roger Williams and turned things around.” The first match of the day saw Bruno

take on its Ancient Eight foe. Things got off to a great start for the Bears, with Josh Durso-Finley ’18 pulling off an exciting overtime victory that set the tone for the crowd’s day-long enthusiasm. But it did not take long for the Crimson to shift the momentum, as it quickly jumped out to a 13-3 lead through four matches. Fortunately for the Bears, the middle weight classes, where they have found the greatest success this season, came next. Steven Galiardo ’17 started off their comeback with an impressive » See WRESTLING, page 3

Tie at No. 15 Cornell gives Bears key point Researchers investigate M. HOCKEY

Late power play goal squashes Brown’s first chance at conference victory since November By MATT BROWNSWORD SPORTS EDITOR

For a men’s hockey team that has won two conference games this season, picking up a point in a 3-3 tie against No. 15 Cornell is an occasion to be celebrated. As it stands, a point for Brown (4-16-5, 2-12-4 ECAC) could be the difference between playing at Dartmouth or Rensselaer in the first round of the playoffs. Avoiding Dartmouth would be the Bears’ goal, as the Big Green is on a five-game win streak against Bruno, including 7-3 and 6-3 drubbings this season. Still, for a team that has not recorded a conference win since Thanksgiving, one point will not make up for a difficult season. “I thought our team played well » See M. HOCKEY, page 2

from top to bottom,” said captain Mark Naclerio ’16. “We were unfortunate to go down a man in the last minute, but our energy was very good, and we had a great game.” The Bears’ penalty kill — an achilles heel each of the past two seasons — came back to bite them against Cornell (12-7-5, 7-6-4). The Big Red started the third period with a power play goal and then sandwiched two Brown tallies with a second goal on the man advantage with 10 seconds left on the clock. Though Brown’s power play has seen much improvementin the last year, its penalty kill has remained one of the nation’s worst. Ranking last in the conference, the Bears’ kill is third-to-last in the country, ahead of newly minted Arizona State and Western Michigan. “Our power play has been collecting a lot so far even though we’ve had few calls for us,” Naclerio said. “But the penalty kill is something

that we definitely have to focus on and figure out.” Tommy Marchin ’19 has been a brilliant bright spot in a challenging season and showcased his ability again Friday, continuing his ECAC rookie of the year campaign with another first-period goal against the Big Red. The first-year’s 13 goals are second-most on the team and eighth in the conference. Zack Pryzbek ’17 has been a pleasant surprise for the Bears as well, scoring his fourth goal of the season to put Brown up 3-2 late in the third period. The fourth-liner is one of two players for Bruno with a positive plus-minus, boasting a plus-two along with Brandon Pfiel ’16. “He’s been great so far,” Naclerio said. “He’s been shooting a lot and playing with high energy and playing really physically.” Max Willman ’18 picked up the other tally for Brown, tying the game at two midway through the third ELI WHITE / HERALD

Captain Mark Naclerio ’16 awaits a pass near the boards. He tallied one assist in the Bears’ 3-3 tie against the Big Red Friday night.

physics of stone skipping Splash Lab study has implications for water toys, naval crafts, basic physics understanding By RACHEL GOLD SENIOR STAFF WRITER

When it comes to skipping stones, kids know to look for the perfect rock. But according to a team of researchers from the School of Engineering, the Naval Undersea Warfare Center in Newport and Utah State University, it is elastic balls that they should be after. In a paper published Feb. 4, the team of researchers offered new insights into the fluid-solid interactions that send “skipping stones” and balls jumping across water surfaces. The result could have implications on anything from pool toys to water skis to inflatable boats for the navy, but the main purpose behind the project was the “advancement of scientific

understanding,” said Allan Bower, professor of engineering and member of the research team behind the paper. In the case of this experiment — part of which took place at Utah State University’s “Splash Lab”, which is run by Tadd Truscott — the scientific understanding came with a hearty dose of fun. “It’s definitely the most fun thing I’ve ever done academically,” said Jesse Belden, researcher at the Naval Undersea Warfare Center and another author of the paper. “There is something about skipping stones that has always intrigued people,” he added. Though the physics of skipping stones across water has long been studied, it “turns out nobody has looked at how squishy objects bounce off water surfaces,” Bower said. The team found that elastic balls “automatically adopt a favorable shape” when they impact the water, deforming into the flattened discs that » See SKIPPING, page 3
