Fine-tuning online education

first_imgAndrew Ho, research director of HarvardX and an assistant professor at the Harvard Graduate School of Education (HGSE), spoke with the Gazette about a recent study that found that interspersing online lectures with short tests improved student performance. The practice cut student mind-wandering by half, tripled the rate of note-taking, and improved overall retention of the material, according to the research, published last week in the Proceedings of the National Academy of Sciences.GAZETTE: In describing the study, senior author Daniel Schacter, the William R. Kenan Jr. Professor of Psychology, said there is “shockingly little” hard scientific data on how students learn online — how useful do you see this new study as being?HO: Of course it’s incredibly important. Dan is a member of our HarvardX Research Committee, which is charged with coordinating and supporting the research mission of HarvardX, and research like this is one reason he’s on that committee, and one of the many ways he’s contributed to our discussions thus far.It’s true that there are fewer scientific research findings in this field than one would expect, but that is rapidly changing, and it’s frankly our mission to change it. One of the challenges to this type of research is that it can be difficult to obtain large sample sizes, but the platform we have is beginning to change that. We are able to capture every mouse click with HarvardX, and that is an incredibly rich resource for research. It’s allowing us to address a number of questions that we hadn’t been able to address in the past, and Dan’s paper is an example of the type of work we want to facilitate.GAZETTE: What was your reaction when you first saw the findings?HO: I think the take-home point from this for our HarvardX research mission is the importance of experimental research. HarvardX is already incorporating the implications of Dan’s findings into its courses — we’re already interspersing assessments with lectures, but the key question is: How do we know if it is working? This type of controlled experimentation is the answer.What Dan’s work allows us to say is that interspersing lectures with tests isn’t just associated with these outcomes — it actually caused them. It is the reason why mind-wandering decreased and note-taking increased. Without this type of rigorous experimentation, all we have is speculation. I think that’s the great opportunity that HarvardX affords, and it’s something that we are primed to take advantage of with people like Dan on the committee.Dan is hoping to replicate this in the HarvardX world, and to ask questions about whether this result can be generalized to other courses or other topics, and whether this leads to greater learning outcomes, which is something we haven’t been able to test yet.GAZETTE: There is still a perception that taking online classes is somehow less educationally valid than being in a brick-and-mortar classroom. Do you see this study as refuting that belief?HO: This is a reminder that online learning is an active process, not a passive process. We are not watching television, we are not watching TED talks, and we are not watching YouTube videos. We are an active participant in a process that is challenging us, and forcing us to think and respond. What this paper shows is that active participation doesn’t just force us to move, it actually focuses us, and elicits behaviors that are associated with active learning.GAZETTE: While this recent paper focuses on online education, researchers have said they would expect to see the same effect in in-person lectures. How do you see the best practices of the virtual classroom affecting real-world classrooms?HO: The world of online education challenges us as instructors to make our teaching good enough to show to the entire world. But part of the HarvardX mission is to make sure that we are having an impact on our students on Harvard’s campus as well — this is not just about how we can distribute our lectures around the world but how we can improve our practice for our students here.I think, in many ways, online education is about putting old pieces together in new ways, but what we find is that the whole is greater than the sum of the parts. We are engaging communities through online discussion forums, and by encouraging constant self-assessment. Students can see their progress is real-time and, as they’re sitting and watching a lecture, they can also track and measure their learning.  As Dan’s work shows, this can be an incredibly motivating and active process.There is as much a lesson here for our classrooms on campus — that if we can break up our presentation into assessable moments, it can improve students’ overall performance. The virtual classroom need not replace the real-world classroom as much as transform it — we can improve our practices by incorporating these new technologies and these new models of interaction. We are active participants, and what this paper shows is that by challenging us to do more than watch, but to think, we cannot help but learn.last_img read more

Jokowi’s traditional attire draws attention to forced eviction of indigenous group

first_imgVarious organizations condemned the East Nusa Tenggara administration’s “repressive” approach toward the Besipae indigenous community, who refused to give up their customary land in Pubabu forest, which the administration claimed as its own. Djemi Amnifu contributed to this story from Kupang. To celebrate Independence Day on Aug. 17 at the Presidential Palace, President Joko “Jokowi” Widodo wore an indigenous outfit from Timor Tengah Selatan regency, East Nusa Tenggara. His choice of attire has brought attention to a land dispute that after years has resulted in the forced eviction of an indigenous community in the regency.Several media outlets ran headlines drawing a connection between the outfit the President wore on Independence Day and the forced eviction, which occurred one day later. The Indigenous Peoples Alliance of the Archipelago (AMAN) said in a statement that joint personnel from the police and public order agency had destroyed dozens of Besipae community settlements built within the Pubabu forest in Linamnutu village of Manuban Selatan district, Timor Tengah Selatan.The incident took place on Tuesday, causing 37 families to lose their homes.”The security personnel verbally and physically abused the community during the forced eviction. They particularly targeted women and children. Witnesses heard three gunshots along the way,” the statement said.AMAN secretary-general Rukka Sombolinggi condemned the incident, calling it “a violation of human rights”. She urged the administration to use a persuasive approach rather than a repressive one.center_img The National Commission on Human Rights (Komnas HAM) released a statement after meeting the community about the dispute recently. Komnas HAM commissioner Beka Ulung Hapsara vowed “to soon arrange a visit to the site” to help find a solution to the case.The Indonesian Forum for the Environment (Walhi) separately explained that similar violence had also occurred in February, in which joint security personnel forcibly expelled three families living in a building claimed by the East Nusa Tenggara administration as its asset.The dispute had apparently lasted for years, after logging in Pubabu forest had depleted the clean water source of the community, a document from Walhi said.The Besipae community on Aug. 17 in Timor Tengah Selatan, East Nusa Tenggara. (Courtesy of ITA-PKK/-)In 2013, when an agreement between the community and the East Nusa Tenggara administration regarding use of the forest ended, the conflict escalated.In 1987, the Besipae community, which had inhabited the forest for generations, gave authorities permission to use the land as a cattle farm, under a collaboration with the Australian government. The agreement was supposed to end in 2012.Two years before the expiry date, however, local authorities proposed an extension. It was rejected by the community, which wanted to return the forest to its “Nais Kio” (prohibited area) status. Nais Kio, according to the Besipae group’s customs, is intended as a habitat for wildlife and should not be managed by anyone. Hunting is prohibited on the land.The administration issued in 2013 a certificate of right of use over a 3,780 hectare area in the forest, which eventually triggered a conflict with the community. Authorities then intimidated the community before forcing them to leave the land, Walhi said.East Nusa Tenggara head of regional revenues and assets, Zeth Sony Libing, told The Jakarta Post on Wednesday that the administration had provided 800 square meters for the 37 families to use.They planned to use 3,780 ha to cultivate moringas and keep cattle. “The administration holds a land certificate to use this land,” he said, claiming that the 37 families had “squatted” on the land.Besides the 800 sq m, East Nusa Tenggara Governor Viktor Bungtilu Laiskodat had permitted the 37 families to work on the 3,780 ha as long as they did not claim ownership of it.Sony claimed that the 37 families were “newcomers” who wanted to profit from the land. He also claimed that the administration had the right to use the land after an indigenous figure, Raja Nabuasa, gave the land to the administration. Raja Nabuasa is dead now.The Walhi head in the province, Umbu Wulang Tanaamahu, told the Post that the families were members of the indigenous community, not newcomers occupying the land like Sony claimed.

Green cleared to return after bowling ban

first_imgSYDNEY Thunder spinner Chris Green has been cleared to return to competitive cricket after biomechanical testing in Brisbane deemed his bowling action to be legal.In January, Green was banned from bowling in all Cricket Australia competitions for three months after testing revealed his bowling elbow would bend beyond the allowable 15 degrees.It ruled him out of the remainder of last summer’s KFC BBL and also put his maiden Indian Premier League (IPL) stint in jeopardy, but the cricketing shutdown due to the COVID-19 pandemic has meant he hasn’t missed any more matches.Green was tested again at the Bupa National Cricket Centre in Brisbane last week and the Thunder announced today that the results showed the off-spinner’s action “performed significantly below the allowable 15 degrees of elbow extension”, clearing him to return.“I feel like I’m in peak physical condition, my batting is going really well and now I’m really excited to get back bowling competitively again,” Green said.“I just can’t wait to play again. I’m so excited to get back out on the field and repay the faith that has been shown in me the best way I know how – by putting out my best effort.”Green’s off-spin and faster ball were the deliveries under review at the NCC and he was tested by University of Queensland biomechanics expert Dr Luke Kelly, who is a consultant for Cricket Australia.Just when Green will return to competitive action is yet to be determined. He was purchased by the Kolkata Knight Riders to play in the IPL, which may reportedly be held in October after it was postponed earlier this year due to the global health crisis.The 26-year-old has also played in domestic T20 leagues in England, the Caribbean, Pakistan and Canada.Last year, he signed a six-year deal with the Thunder in the Big Bash, the longest in tournament history.last_img read more

Price partners with Microsoft for criminal justice data project

first_imgPeter Griffin, a research assistant for the Center for Social Innovation and the Safe Communities Institute, commented on the importance of data collection to help inform the community about local issues.  The initiative will also implement a series of community conversations to promote interaction between law enforcement, nonprofits, government agencies and other community members as well as inform the public in these neighborhoods about public safety on and off campus.  “[NDSC] helps to broaden your understanding of how people are living,” said Caroline Bhalla, Sol Price Center for Social Innovation managing director. “You can’t just look at crime and all of a sudden you understand everything about the neighborhood. If you look at [crime, demographics, arrest, traffic collision data], you start to get a fuller picture of what’s going on in these neighborhoods.” Along with Microsoft, other collaborators include USC Safe Communities Institute, the Urban Institute’s National Neighborhood Indicators Partnership and the Los Angeles Police Department. Microsoft helps fund the project and is part of the steering committee that partakes in the initiative’s community meetings.  A program under the Sol Price Center for Social Innovation is collaborating with Microsoft and other organizations for the Criminal Justice Data Initiative to collect data on neighborhood crime in Los Angeles. The Neighborhood Data for Social Change program will study its connection to homelessness, housing, education, economic development and jobs. “Every single person wants to feel safe, and you know the person next to you and the person that lives across the street from you wants to feel safe,” said Griffins, a graduate student studying public administration. “So that’s why we’re looking at the neighborhood level and [breaking] it down to what is it that the data says versus what is the perception.” Before collaborating with Microsoft,  the project collected data on crimes against persons and property, said Erroll Southers, director of the Safe Communities Institute, which is also housed in Price. Now, the project will analyze  criminal justice data like arrests, stops and citizen complaints to help the community design strategies to improve its neighborhoods and collaborate with local law enforcement. “We are trying … to determine what kind of information communities can take away … to design a strategy to make their neighborhood safer,” Southers said. “What we need to do is to find some kind of positive metric out of this project … law enforcement traditionally and organizationally has always measured negative when it comes to statistics. We’re trying to determine if there’s a way to determine positive outcomes for law enforcement.”center_img “It’s nice to see organizations like Microsoft get behind an effort like this. It shows how innovative they are in their thinking and that’s huge,” Southers said. “For that reason, we are working very hard to determine what kind of effectiveness this project can have … so hats off to Microsoft for having the confidence and trust in our centers to do something like this.”  This one-year initiative will track criminal justice trends in L.A. neighborhoods, including the rates of arrest and the number of incidents in which law enforcement use force. Neighborhood Data for Social Change aims to increase public safety in the local community and initiate conversations between local law enforcement and the neighborhood.  The Sol Price Center for Social Innovation is working with Microsoft and other organizations on a one-year program to track criminal justice trends in Los Angeles neighborhoods. (Andrea Diaz | Daily Trojan) “One of the things that we’re doing … is trying to get people to talk to each other who may not always talk to each other,” Bhalla said. “We’ve invited USC students as well as staff and faculty to attend these convenings and also to take part in this project. So they’re having the chance to learn about public safety here on campus but also off-campus.” By collecting data on criminal justice in L.A. County neighborhoods, Griffin hopes to empower communities to implement their own methods of public safety.  “It’s one thing to read an excel spreadsheet on what crime is in your area, but to visually see it and make it available for people all across Los Angeles … and give them the tools to empower themselves, to learn more about their community,” Griffin said. “Being able to empower your community is a crucial, fundamental issue for this project.last_img read more

Millionaire Steve Smith on a roll both on and off the field!

Powered by Firework Steve Smith’s cricketing career has had its highs and lows, but these days it seems like fortune is indeed by his side. On the field his twin centuries in both innings of the first Ashes Test helped Australia to comeback over England at Edgbaston. And now reports claim that off the field, Smith’s business and investment ventures have turned into an overwhelming profit. According to The Australian Financial Review, the former Australian skipper has turned a $1,00,000 investment in an Australian mattress retailer (Koala Mattress) into a whopping $12.1 million profit.Advertisement On July 2015 Steve Smith invested for 10 percent of the company just before he was declared the Australian Test captain. Since then, the company has built a solid customer base of more than 2,00,000 people and is now valued at over $150 million. His ownership helped the company rake in more investors as he became their brand ambassador as well. Smith, who is among the top five earners of Cricket Australia also has a $2 million contract with Rajasthan Royals in the Indian Premier League.Advertisement However, last year saw Smith reportedly lose up to $7 million during the ball-tampering scandal. He was heavily booed throughout the World Cup and the Ashes series but the Aussie superstar did not let it distract him. With a career average of 62.96 in test cricket, he is now second only to the great Don Bradman. Looks like fortune favors the brave after all. Advertisement Advertisementlast_img read more

DOHERTY SLAMS GOVERNMENT OVER LOW TAXES FOR MEGA-RICH AMERICAN COMPANIES

first_imgSinn Féin Finance Spokesperson Pearse Doherty TD said the Irish Government ostrich mentality was responsible for Ireland’s tax reputation being damaged. Deputy Doherty was responding to comments from US President Barack Obama concerning Ireland being a low tax jurisdiction in use by US companies trying to avoid. “It’s two years now since an investigation in the US heard sworn testimony from the heads of Apple that Ireland had allowed the company a special tax rate ensuring an incredibly low effective tax rate. But talk of Ireland being a channel for aggressive tax planners has been rumbling on for a while,” said the Donegal TD. “The response of the Irish Government, and of Fianna Fáil and establishment agencies has been to deny, deny, deny. They seem to see this as some sort of perverse patriotism, when in fact in it this ostrich approach that has left Ireland exposed and potentially under threat of job losses. Multinational companies have made an invaluable contribution to the Irish economy and it is vital that we keep their revenue and the jobs created – but also, that we are aware if any event or sequence of events has the potential to threaten investment in Ireland and that we cancel the threat, or plan for it. That’s good governance.“Already, at Sinn Féin’s request, an Oireachtas sub-committee was established to examine Ireland’s role in international tax laws. However the refusal of other party representatives on the committee to invite in business leaders for questioning severely undermined the committee’s ability to function.“Last year I also presented the Government with legislation to ensure Irish incorporated companies, non resident anywhere in the world, would be considered resident in Ireland for tax purposes. The Irish Government refused to accept the legislation, claiming there was no problem, but months later introduced a watered down clause in Finance Bill 2013. After intense pressure for our party and other responsible agencies, the Government is now looking at other measures to ensure Ireland is not seen as a tax haven – we can only hope it’s not too late.“Ireland should continue to offer a competitive, efficient and fair tax system to international business. We should be conscious of our global responsibilities and ensure that no company is able to use Ireland in a scheme that contributes to damaging the tax generating abilities of developing nations. “In addition, we believe strongly that the tax levied on MNCs should be no more and no less fair than the tax levied on indigenous companies, who generally pay the headline rate of corporation tax and cannot use international tax planning to reduce, proportionately, their tax bills. Sinn Féin will continue to work to that end.” DOHERTY SLAMS GOVERNMENT OVER LOW TAXES FOR MEGA-RICH AMERICAN COMPANIES was last modified: July 25th, 2014 by John2Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:american companiesDeputy Pearse DohertyloopholePresident Obamataxlast_img read more

Jitan Ram Manjhi says party will go it alone in 2020 election

first_imgFormer Bihar Chief Minister and Hindustani Awam Morcha (Secular) president Jitan Ram Manjhi said here on Friday that the party would contest the next Assembly election on its own. Mr. Manjhi alleged that the NDA and the grand alliance had let down his party during the previous elections. The next Assembly election in Bihar is due in November 2020.“Both the NDA and the grand alliance had cheated us in elections… so my party men have suggested that we contest the next Assembly polls in the State on our own,” Mr. Manjhi told presspersons soon after launching the party’s membership drive in Patna. “Whatever seats we win would be our own and on our strength,” he said. Out of the State’s 40 Lok Sabha seats, Mr. Manjhi’s party contested three — as a member of the Mahagathbandhan (grand alliance) — and drawn a blank. “My party was given three seats in last parliamentary elections but only I, from Gaya (reserved) seat, was contesting as our party candidate as the other two seats had Congress and RJD candidates,” Mr. Manjhi said. “This decision had angered my party leaders and workers.” “Now, they [party leaders and workers] have suggested to contest the Assembly poll in 2020 on our own strength.”“Mr. Manjhi had not said that his party would come out of Mahagathbandhan… he has only said that his party would contest the next Assembly poll on its own,” an RJD leader said, declining to be identified.However, a leader of the ruling JD(U) took a dig at Mr. Manjhi’s statement. “RJD-led Mahagathbandhan is a sinking ship and it’s natural that its constituent parties would like to abandon this ship in next Assembly poll,” the leader asserted, speaking on condition of anonymity.last_img read more
