first_imgTomorrow, Yes will be inducted into the Rock and Roll Hall of Fame. In celebration of this historic event, the prog rockers have announced a full U.S. tour, which they are calling “YESTIVAL,” a full festival experience. The summer tour will explore nine of the band’s greatest studio albums, with stops in Baltimore, Brooklyn, Cleveland, Phoenix, Oklahoma City, Las Vegas, and Los Angeles.The band is expected to announce more dates soon, but for now we’re excited about this 17-date run. The lineup will include Steve Howe (guitar), Alan White (drums), Geoff Downes (keyboard), Jon Davison (vocals), and Billy Sherwood (the late Chris Squire’s chosen successor on bass). Founding member Jon Anderson will be there to accept their Rock and Roll Hall of Fame recognition, but will not join the tour.Producer Todd Rundgren will tour as support for YESTIVAL, as will Carl Palmer’s ELP Legacy playing tribute to Emerson, Lake & Palmer.Yes’ YESTIVAL 2017 Tour Dates:08/04 – Greensboro, NC @ White Oak Amphitheatre08/05 – Boone, NC @ Holmes Convocation Center08/07 – Baltimore, MD @ Pier Six Pavilion08/08 – Upper Darby, PA @ Tower Theater08/10 – Mashantucket, CT @ MGM Grand at Foxwoods08/11 – Brooklyn, NY @ Ford Amphitheater08/12 – Holmdel, NJ @ PNC Bank Center08/16 – Greensburg, PA @ The Palace Theatre08/17 – Clarkston, MI @ DTE Energy Music Theatre08/19 – Elgin, IL @ Festival Park08/20 – Cleveland, OH @ Jacobs Pavilion08/22 – Oklahoma City, OK @ The Zoo Amphitheatre08/23 – Sugar Land, TX @ Smart Financial Centre08/25 – Phoenix, AZ @ Celebrity Theatre08/26 – Las Vegas, NV @ The Joint08/29 – Los Angeles, CA @ Microsoft Theater09/03 – Tulalip, WA @ Tulalip Amphitheatrelast_img read more

first_imgWhile the proliferation of massive open online courses (MOOCs) has expanded learning opportunities for individuals around the world, the digital classroom is also subject to many of the same issues as the traditional one — such as cheating.In a new working paper, researchers at Harvard University and the Massachusetts Institute of Technology (MIT) have identified a new method of cheating specific to open online courses, and have recommended a number of strategies that are proving effective in preventing it.The working paper, “Detecting and Preventing ‘Multiple-Account’ Cheating in Massive Open Online Courses,” was published today on arXiv.org, an online repository for electronic preprints.Isaac Chuang, a professor of electrical engineering and physics, senior associate dean of digital learning at MIT, and one of the authors of the working paper, explained that he and his colleagues were inspired to examine the problem in an effort to better understand all the opportunities that online courses provide, in both learning and cheating.“If learners in some online courses are circumventing the learning process and obtaining certification without going through the traditional routes of assessment and feedback, then the certification does not necessarily imply that they learned anything. This could seriously devalue MOOC certification,” Chuang said. “This is a well-known issue in academics, and it’s happening in new ways in online settings. We want to understand and address this issue as online education continues to grow.”Andrew Ho, a professor at the Harvard Graduate School of Education, chair of the HarvardX research committee, and an author of the working paper, added that the paper describes “a new cheating technique that is particular to MOOCs. It is enabled by specific design features, including the ability to create multiple accounts for free. This is a method of cheating that allows you to acquire a certification for a course in an hour, which is not possible through conventional cheating approaches. This is cheating of a different kind.”CAMEO usersWhile analyzing data gathered from learners using the edX online learning platform, the researchers noticed that certain users were answering assessment questions “faster than is humanly possible,” according to Chuang. Upon further examination, the researchers realized that a number of learners appeared to be employing a cheating strategy they refer to as “copying answers using multiple existences online” (CAMEO).In this method of cheating, a user creates multiple accounts, one of which is the primary account that will ultimately earn a certificate. The other accounts are used to find or “harvest” the correct answers to assessment questions for the master account.To determine the amount of cheating occurring in classes where learners can obtain certification for passing the course, the researchers developed an algorithm that can identify CAMEO users. The algorithm searches for pairs of related accounts in which one account responds to most of the answers incorrectly and the other provides mostly correct answers on the first attempt. Activity time stamps are then reviewed to see when the account suspected of harvesting answers solved a particular problem just after the master account did. The algorithm also looks to see whether related accounts might share IP addresses across multiple courses.The researchers examined data gathered from 1.9 million course participants in 115 MOOCs offered by HarvardX and MITx from the fall of 2012 through the spring of 2015. They discovered that in 69 courses where users were found to have been employing the CAMEO strategy, 1.3 percent of the certificates earned (1,237 certificates) appeared to have been obtained through such cheating. Additionally, the researchers found that among earners of 20 or more certificates, 25 percent appeared to have used the CAMEO strategy. In some courses CAMEO users may account for as many as 5 percent of certificates earned.Although these percentages are lower than the prevalence of reported cheating, which by some accounts is greater than 50 percent, the authors argue that these percentages are nonetheless significant. “This is not an isolated incident of copying on part of one assignment,” Ho says. “This is the wholesale falsification of a certificate.”CAMEO use was found to be higher among young, less-educated males outside the United States. The rate among U.S. users was particularly low, at 0.4 percent of certificates earned. The authors observed that these rates may correlate with the perceived value of the certificate across different countries.The prevalence of CAMEO use was highest in government, health, and social science courses, where 1.3 percent of certificates were earned by employing the cheating strategy, and lowest in computer science courses, where just 0.1 percent of certificates were obtained using the technique.Prevention techniquesThe authors outlined a number of strategies to prevent cheating in online courses, including restricting solutions to assessments until after assignments are due, and randomizing questions so that each learner receives a customized set of problems.However, some of these strategies are costly or may limit learning opportunities. “We may face a tradeoff between enabling learning and preventing cheating,” Chuang noted.The researchers found that in the science, technology, engineering, and mathematics (STEM) courses where such techniques may have been employed, CAMEO use accounted for just 0.1 percent of certificates earned, as opposed to 1.2 percent of certificates earned in courses that did not use any prevention strategies.While techniques including randomization are easy to employ in STEM courses, Chuang noted that they are more challenging to implement in humanities courses, where multiple-choice questions are commonly used as part of the assessment process. Nonetheless, the researchers hope that their findings will inspire course content creators to implement some of the prevention strategies they have outlined and that this research will inspire further evaluation of cheating in MOOCs.“One of the most interesting lessons from the paper is that there are ways to mitigate cheating that are straightforward and implementable by the teams creating online course content,” Chuang said. “We also expect platform improvements, such as virtual proctoring, to help reduce cheating.”“This paper addresses a growing challenge as higher education digitizes: ensuring that the work that students do is their work,” said George Siemens, executive director of the Learning Innovation and Networked Knowledge Research Lab at the University of Texas at Arlington, who was not involved in the research.“MOOCs, and in the case of this paper, the development of multiple online identities, present a new set of challenges for academics,” Siemens said. “The stakes in learning can be high, since academic performance can influence job opportunities. Ensuring that work is done by the student proclaiming to have done it will continue to be a challenge online and in classrooms.”last_img read more
