Harvard and MIT release working papers on open online learning

first_imgHarvard University and the Massachusetts Institute of Technology (MIT) today released a series of working papers based on 17 online courses offered on the edX platform. Run in 2012 and 2013, the courses drew upon diverse topics — from ancient Greek poetry to electromagnetism — and an array of disciplines, including public health, engineering, and law.The series features detailed reports about individual courses; these reports reveal differences and commonalities among massive open online courses (MOOCs). In the coming weeks, data sets and interactive visualization tools will also be made available.Led by Andrew Ho of Harvard’s Graduate School of Education and Isaac Chuang of MIT’s electrical engineering and computer science and physics departments, the effort was in service of a mutual goal — “to research how students learn and how technologies can facilitate effective teaching both on-campus and online” — part of a mission statement established when MIT and Harvard joined to form edX, a nonprofit online learning platform, in May 2012.The papers analyze an average of 20 gigabytes of data per course and draw on interviews with faculty and course teams as well as student metrics.Key takeaways Course completion rates, often seen as a bellwether for MOOCs, can be misleading and may at times be counterproductive indicators of the impact and potential of open online courses. The researchers found evidence of large numbers of registrants who may not have completed a course but still accessed substantial amounts of course content. Across the 17 HarvardX and MITx courses covered in the reports, 43,196 registrants earned certificates of completion. Additionally, 35,937 registrants explored half or more of the units in a course without achieving certification.“We found students in the courses who engaged with every single piece of the courseware, students who only read text or viewed videos, students who only took assessments or completed problem sets, and students representing nearly every possible combination of these behaviors,” said Chuang. “Experimentation is part of the learning process.”An additional 469,702 registrants viewed less than half of the units in a course and another 292,852 registrants never engaged with the online content. In total, there were 841,687 registrations from 597,692 unique users.The reports note that many faculty encouraged learners to participate in the course experiences in whatever ways they found useful, whether or not that involved trying to earn a certificate. For such faculty, the participation of engaged auditors was just as important as the participation of those who completed the assessments of the course.“A fixation on completion rates limits our imagination of what might be possible with MOOCs. A better criterion for success might be for students to complete more of the course than they thought they would, or to learn more than they might have expected when they first clicked on a video or course forum,” said Ho.Most MOOC attrition happened after students first registered for a course. On average, 50 percent of people left within a week or two of enrolling. After that window, attrition rates decreased substantially. The average probability of a student ceasing to engage in the second week of the course declined to 16 percent.While the persistence rates in MOOCs look very different from those of conventional courses in higher education, they look very similar to how people interact with other Web-based media such as video or social network sites. Many registrants briefly browse a MOOC, while a smaller group persists and becomes more engaged over time.The asynchronous nature of the HarvardX and MITx courses also turned out to be an important factor related to engagement. Some students registered for courses months in advance of the start date; others registered months after the course had launched.In some circumstances, students joined courses in the week before the deadline for all graded materials, completing enough assessments to earn a certificate in the final seven days. In some courses, as many as one in five enrollments took place after the course certificate was no longer available.Given the scale of some MOOCs, small percentages are often still large numbers of students — and signify a potentially large impact.Demographic information about registrants can be misleading without context. The most typical registrant in these initial courses was a male with a bachelor’s degree, 26 or older. However, that profile describes less than one in three registrants (222,847, or 31 percent).A total of 234,463 (33 percent) registrants reported a high school education or lower; 45,884 (6.3 percent) reported that they were 50 or older; and 20,745 (2.7 percent) had IP or mailing addresses from countries on the United Nations’ list of least-developed countries.“While typical MOOC registrants have a college degree already, hundreds of thousands of our registrants do not. Many of our MOOC registrants are from the United States, but 72 percent are from abroad. These MOOCs are reaching many nontraditional and underserved communities of students, very different from typical students on campuses at traditional universities,” said Chuang.One of the most interesting subpopulations: the group of people who enroll in and complete multiple courses. More than 4,000 registrants across HarvardX and MITx earned more than one certificate, including 1,912 who earned at least one certificate from each institution. Seventy-six registrants earned five or more certificates.“Context is so important to understanding these results,” added Ho. “A graduate-level course in public health should attract different registrants, on average, than an introductory physics course, or a course on global poverty. In this light, it’s wonderful that so many students are engaging so deeply in courses across topics and institutions.”Forward thinkingLooking ahead, Chuang and Ho view the publication of the working papers, and the open sharing of such data, as a key activity in a broad, positive dialogue happening in higher education.Specifically, they emphasize that the rise of MOOCs has sparked and encouraged experimentation in teaching and in pedagogical research, benefiting both teachers and students. New tools, they say, give faculty more flexibility and offer novel opportunities to run experiments and gather data. Likewise, online-learning platforms put students in the driver’s seat, allowing them engage in a manner that suits individual needs.“This isn’t just about MOOCs,” said Ho. “This is about the democratization of learning: Learners are in control. We are at the beginning of an exciting effort to understand how people learn and how to educate well and effectively at scale.”Finally, the researchers expect the research to serve as a benchmark for future studies on MOOCs and support further work in the science of learning.“The story hidden underneath this series of reports may be this: Institutions like ours are coming to appreciate how cross-institutional educational collaborations involving many students and many courses can open new routes to understand and improve student learning — making a difference around the world and back here on campus,” said Chuang.The lead authors of the HarvardX and MITx course reports were Justin Reich, Richard L. Menschel HarvardX Research Fellow, and Daniel T. Seaton, postdoctoral research fellow at the Office of Digital Learning at MIT.An event from 6 to 7:30 tonight at HGSE will feature discussion of the reports among faculty and researchers. It will be live-streamed.To learn more:Course ReportsPilot Data Visualizations (created by Sergiy Nesterko, HarvardX Research Fellow)Courses on edX.orglast_img read more

Brodosplit delivered a new ship for the fleet of domestic nautical tourism

first_imgToday, in the Shipbuilding Industry Split, Newbuilding 546, a nautical tourism ship built for a domestic client, the company Tajna mora doo, owned by the Marunčić family from Omiš, was laid in the sea.The ship is 48,38 meters long, 9,5 meters wide, 2,40 meters deep, 3,82 meters high and 497 tons gross.

Builder Totalindo eyes Rp 3 trillion in contracts in 2020

first_imgPublicly listed construction company PT Totalindo Eka Persada has achieved 10 percent of its target to book Rp 3 trillion (US$218 million) in new contracts in 2020, following its weak financial performance and plummeting share prices last year. Totalindo booked Rp 309.1 billion in new projects by February, the company’s director Eko Wardoyo said during an event at the Indonesia Stock Exchange (IDX) in Jakarta on Friday. The projects include Sky House apartment in Alam Sutera, Tangerang, Banten; Hotel Lido Extention in Sukabumi, West Java; and Halam Network International.  The company will also continue construction of carry-over projects from 2019 valued at Rp 1.43 trillion, including 31 Sudirman Suites in Makassar, South Sulawesi; Kingland Avenue apartment in South Tangerang, Banten; as well as Nuansa Cilangkap and Klapa Village Tower B in East Jakarta. The projects will go ahead, Totalindo executives said, although the company booked Rp 30 billion in losses in the third quarter of 2019, the latest available financial performance indicator.“[The loss] was due to tax audits in 2016, which had to be included in our September 2019 financial report. We had to pay Rp 64 billion in tax with [around] Rp 30 billion in penalties,” Eko explained. The figure was jarring because in the second quarter of 2019, the company recorded Rp 60 billion in profit, a 46.3 percent increase from the quarter before. The company also increased its revenue by 63.5 percent to Rp 631 billion in the third quarter of 2019, from Rp 386 billion the previous quarter. In addition, the price of Totalindo’s shares, which are traded under the code TOPS on the IDX, nosedived throughout 2019. In the past year, the stocks have fallen 93.79 percent from a price of Rp 805 per share to Rp 50 at close of trading on Friday. “Aside from TOPS, other issuers, both private and state-owned, recorded similar performances because the property sector is [limping]. The share prices of construction issuers generally declined, but TOPS’ plunge was quite deep,” Eko said. The IDX recorded that the property, real estate and building construction sector has fallen 9.53 percent year-to-date, a steeper decline than the Jakarta Composite Index, which fell 5.67 percent during the same time period.

FUN Golf gets families playing

first_img Fun is the name of the game! That’s the promise to families who can have a whale of a time while getting into golf. Golf Kingdom in Essex is at the heart of a joint project with England Golf to highlight golf as a great game for all the generations to play together. It follows England Golf’s Family Golf Month and is attracting families to try the game by joining a three week FUN Golf Course at any time until November and enjoying Adventure Golf on the Moby Golf course. Each one-hour FUN Golf session is delivered by a PGA professional using adapted equipment, with colourful clubs and tennis-style balls.  Players can also ‘warm up’ before each session, hitting against giant targets on a large inflatable.  It’s anticipated that over 250 people will take the FUN Golf courses and they can then move on to other opportunities, including coaching with PGA professionals. It is expected there will be a good level of transition from FUN Golf to the traditional golfing game.  “It’s golf, but not as you know it!” said Scott Cranfield from Golf Kingdom at Chadwell Heath, Essex. “Golf is a terrific game for all the family and we encourage lots of laughter. There’s no stuffiness here!”  England Golf is also working with Golf Kingdom to help them understand their customers and potential customers. This information is being used to shape publicity for the campaign on social media and with other promotional material. England Golf and Golf Kingdom will also survey Moby Golf and FUN Golf customers to find out more about what families want from golf and what they see as barriers to participation. Claire Hodgson, England Golf’s Head of Participation, said: “It’s great to be able to show families that golf is a game which all the generations can enjoy together. We’re delighted to be working with Golf Kingdom and look forward to sharing the results of this project to help other clubs and golf centres to attract more families.” Kate Cooper, Managing Director at Golf Kingdom, added: “The feedback so far from people who have taken part in our FUN Golf course has been very positive.  Many have said that it is a great introduction into a sport that they have never played before. We have had many family situations, where mum and dad have both enjoyed playing alongside their children.  We’re looking forward to many more taking part.” To find out how to join a FUN Golf course and to watch FUN Golf in action visit www.golfkingdom.net/fun/course 8 Aug 2016 FUN Golf gets families playing last_img read more

Steelers, Bengals fall to inferior opponents

first_imgThe Steelers and Bengals totally outplayed their inferior opponents but both lost. In what were supposed to be easy wins against opponents with 2-7 records, both fell short, keeping the AFC North race tight. The Kansas City Chiefs have struggled all season but were 2-2 in their last four games coming into Sunday’s game against the Steelers. This wasn’t supposed to be a real test, but once again Pittsburgh’s special teams gave up a 97-yard kickoff return by Jamaal Charles for a touchdown that ended up being the difference in the 27-24 overtime defeat. Even though the special teams were able to hold the Chiefs in check for the rest of the game, the damage had been done. The offense accumulated yardage on the ground and through the air, but penalties and not being able to score in the red zone cost the Steelers the game.Ben Roethlisberger was 32 of 42 for a whopping 398 yards and three touchdowns and Rashard Mendenhall looked impressive once again with 80 yards on 21 carries. Willie Parker saw more action picking up 24 yards on six carries. Mendenhall also looked impressive as a receiver catching four passes for 35 yards. Hines Ward had a great game catching 10 passes for 128 yards and Santonio Holmes had seven for 86 yards and Heath Miller seven for 95 yards.Compare these numbers to K.C.’s numbers and it should have been a lopsided victory for the Steelers. Matt Cassel was 15 of 30 for 248 yards and two touchdowns, no interceptions. His primary target was the newly acquired Chris Chambers who had four catches for 119 yards. The Steelers held their running game in check holding Charles to just 58 yards on 17 carries. But the only thing that really matters is the final score. Two costly interceptions killed drives that would have been easy scores; either field goals or touchdowns, which. along with the kickoff return, ended up being the difference in the game.With the Steelers defeat, all the Cincinnati Bengals had to do was go out and take care of business against the lowly Oakland Raiders, but like the Bengals of old they didn’t get the job done, thus keeping the door open for the Steelers to come back and take the AFC North title.Much like the Steelers, the Bengals dominated the game but allowed the Raiders to come back from a 17-10 deficit in the final minute for the victory. Brad Gradkowski threw a 29-yard touchdown pass to Louis Murphy with 41 seconds left to tie the game, and then Andre Caldwell fumbled the kickoff that led to Sebastian Janikowski’s field goal that won the game. Looking at the numbers it should have been a blowout, but the only thing that matters is the final score.In other games involving the AFC North, the Cleveland Browns and the Detroit Lions, two 1-8 teams, had the best offensive game of the day with the Lions pulling out a 38-37 victory. The Baltimore Ravens kept it close and exciting but in the end the Indianapolis Colts remained undefeated (10-0) with a 17-15 win.This week the Bengals face the Browns, and the Steelers play the Ravens in Baltimore. This is a must game for both teams. The Steelers must win to stay close to the Bengals, and the Ravens must win to stay in the race for a playoff birth.The division leaders are Indianapolis (10-0), New England (7-3), San Diego (7-3) and the Bengals (7-3). This leaves the Steelers (6-4) battling with the Broncos (6-4), and the Jaguars (6-4). The Houston Texans (5-5) were lost to the Tennessee Titans (4-6) Monday night. Teams with outside chances are the Miami Dolphins (5-5) and the Ravens (5-5).The Bengals are still in the driver’s seat, but they must take care of business against the Browns and the Lions in their next two games to prove that they are not the Bengals of old. FILLING IN—Steeler quarterback Charlie Batch (16) directs the team during overtime against the Kansas City Chiefs, Nov. 22, in Kansas City, Mo.
