Skype en classe

Educators Move Beyond the Hype Over Skype

Educators are now using the videoconferencing tool to connect foreign-language students to native speakers, hold virtual field trips and host conversations with scientists and other experts

For first-time users, there is perhaps an undeniable novelty to Skype videoconferencing software that allows students to meet—virtually—with someone anywhere in the world, in real time, and at no cost.
But even the most fervent proponents of its use in education insist curiosity alone isn’t enough to justify dedicating class time to videoconferences. Instead, they say Skype must target specific educational goals.
“You want an opportunity for your kids to communicate with other kids about what they are learning,” says Becky Fisher, the director of educational technology and professional development for the 13,000-student Albemarle County school district in central Virginia. But “we can’t let the abundance of connectivity keep us from thinking,” she says.
While conceding the potential for frivolous use of Skype, its advocates say the tool can be particularly valuable for connecting foreign-language students to native speakers, holding virtual field trips, and visiting with real-world subject experts while saving precious funds and preventing logistical headaches. In many cases, teachers are reporting that aspects of video communication actually make teaching and learning more effective than the comparable in-person experiences.
Ironically, the biggest challenge for many Skype pioneers in education may not be convincing their supervisors of its educational value, but finding efficient ways
to connect with like-minded Skype partners. Skype Technologies, the tool’s developer, is in the first stages of developing a social-media Web destination for “Skyping” educators, but as of press time, it was available only to 300 selected applicants on a pilot basis.
Skype Technologies, based in Luxembourg, has offered the free video and phone conferencing service since 2003, though at the time, many schools weren’t equipped with the technological hardware, like webcams, and high-speed connectivity necessary for video correspondence. But with improving technology infrastructures, modifications to the Skype software, and an increasing push for teachers to find new ways to give their students educational experiences, educators appear to have turned more to Skype later in the decade.
Skype Technologies also offers for-pay services to businesses as a provider of Web-based phone networks. Google Talk also includes free voice and video features for its users, though Skype appears to be the more common method of video communication among educators.

'Endless' Potential

Skype’s proponents insist the wave of teachers integrating videoconferencing into the classroom represents the leading edge of what soon will be considered mainstream educational practice.
“[The potential] is so endless,” says Colleen Blaurock, who teaches Spanish at Perry High School in Perry, Ohio, about 30 miles northeast of Cleveland. Blaurock early in 2010 connected her students with a large population of native Spanish-speaking students in nearby Painesville for regular Skype conferences, in which students would converse in both English and Spanish.
“What I’ve found is that the learning transcends the Skype environment,” Blaurock adds. “The kids saw a reason in a traditional classroom to learn. And Skype helped make that happen.”
In addition to language studies, proponents of Skype in the classroom point to other Skype-friendly educational environments: geography and other social studies, where virtual field trips can easily be aligned to a course curriculum, and English courses, with the possibility of hosting a book’s author through a virtual visit.
Pavel Samsonov, an associate professor of education at the University of Louisiana-Lafayette, says his research found Skype could also prove critical in middle and high schools for helping students keep pace when they are absent because of illness, college visits, school suspensions, or pregnancy.
“When it comes to math and science, if you miss a couple of classes, you can be in very poor shape, and it may become impossible to catch up,” says Samsonov, whose pilot study of three homebound Louisiana high school students was funded in part by Skype. He added that while Skype could help students avoid such setbacks, it is critical that schools in those situations treat videoconferencing as mandatory, not optional.

Worldwide Audience

In addition to combating logistical hurdles, educators say targeted use of Skype can bring pedagogical benefits, whether it makes students conduct research necessary for a video presentation more seriously, encourages instructors to focus on broader concepts instead of individual problems because tracing and fixing student work directly is more difficult, or exposes students and teachers to real-time technology problem-solving.
In Virginia’s Albemarle County district, Fisher encourages her teachers to use Skype and other collaboration tools because she believes there is no equivalent for giving students an audience for their work. She compares it to a team sport, in which the Skype activity is game day, and other days of class spent in preparation are like after-school practices.
“The fact that there’s a game on Friday night ramps up practice on Monday afternoon,” says Fisher. “When you look at what the Web allows us to do, every kid in your classroom can have a worldwide audience. That’s true for writing, and that’s true for some of these oral-presentation types of things,” such as videoconferencing.
Chris Frank, the founder of the San Francisco-based Ignition Tutoring, which provides its services via Skype, says he and his staff of about 25 tutors must teach students on a more conceptual level than simply assisting them with homework problems.
“From in the home, [tutors] usually have the book right there. You just get stuck working through homework problems a lot,” says Frank, whose service caters mostly to middle and high school math and science students. “When doing [tutoring] in Skype, if you are working on logarithms today, then you say, ‘All right, let’s go through logarithms.’ It forces you out of that habit of helping with homework.”
Amy Tharp, a literacy specialist for the 6,000-student Littleton, Colo., school system, says an elementary school Skype project has helped both her and her students become more accepting of technological hazards that are commonplace in the real world.
Students at the district’s Highland Elementary School have been in regular contact with world traveler Dean Jacobs during his journeys through Africa for his guidance on research about mountain gorillas. Through it all, Tharp says, she and her students have learned how to manipulate Skype’s voice, video, and chat features to make sure they maintained connectivity with Jacobs at remote outposts.
“Once you go through the first couple times, you tend to gain a sense of calmness about it,” Tharp says. “The more we dropped those calls and had to reboot and adjust, the more comfortable I got with being OK with problems happening. It’s helped me transfer that to other technology skills personally.”

'Skype in Schools' Wiki

As Tharp and others become more comfortable with the software, they’re looking for more like-minded educators to connect with.
Skype in Schools is a wiki that allows educators to post messages about their Skype experiences and seek out partners. And Chatting Across the USA aims to connect elementary school teachers who want to participate in the Web Chat Challenge first conceived by Cherrie MacInnes, whose 3rd graders at Washington Street Elementary School in Brewer, Maine, about a year ago held videoconferences with classes in all 50 states using either Skype or Google Chat.
But according to research funded by Skype Technologies, finding other teachers to connect with remains more frustrating for educators interested in using Skype than gaining permission from administrators and school technology personnel to use the software.
As a result, Skype in Education, a social-networking Web resource for educators who want to forge ties with similarly minded colleagues, was unveiled in beta form in December to 300 people chosen from more than 3,000 who applied to be part of the site’s pilot phase, says Skype spokeswoman Jacqueline Botterill.
Botterill, who is heavily involved in the Skype in Education effort, says the hope is that the site will be a hub for educators not only to link up with one another, but also to find guests to bring in for virtual visits, and to obtain information on best practices for using videoconferencing and other such features in the classroom.
“We haven’t put any big targets around this, just because we have no idea how viral this might become,” Botterill says. “There are some really passionate educators out there who’ve been trying to do what we are doing. … We’re not trying to become an authority on this. We’re just trying to help those communities come together.”
Until then, teachers should still try to seek out partners on their own, Skype’s boosters say. More willing partners are out there, they say, than educators might think.
“I thought it would be a tough sell,” Blaurock says of her Spanish-English correspondence project. “It involved doing something you’re not used to doing. It involved taking a risk and knowing it might fail. It involved the creation of new materials.”
“I was fearing that others might not be willing to take that risk,” she adds. “And I was wrong.”

Bullies

 

Study Disputes Myth of School Bullies' Social Status

Premium article access courtesy of Edweek.org.
In the movie “Mean Girls,” head plastic Regina George tortures her North Shore High classmates of all stripes, including her supposed best friends. At Springfield Elementary, where Bart Simpson goes to school, Nelson Muntz, the oversized dimwit with the distinctive laugh, is the cartoon series’ bully.
A new study suggests that, in reality, neither of those students would be the aggressors on campus.
Robert W. Faris, an assistant sociology professor at the University of California, Davis, spent several years surveying students at middle and high schools in rural and suburban North Carolina. The results of his research are published in this month’s edition of the American Sociological Review.
He found that students in the middle of the social hierarchies at their schools, rather than the most popular or the most socially outcast, are more likely to be bullies.
“I think there’s kind of a simple explanation: These kids view aggression as one tactic for gaining or maintaining their social status,” Mr. Faris said. “This is not the only way that kids climb socially. There are a lot of other ways—much more effective ways: being good in sports, being pretty, being rich, if you’re funny, if you’re nice.”
Mr. Faris and UC-Davis colleague Diane Felmlee mapped social networks, based on students’ responses to surveys about who their friends were and whether those students listed them in turn, allowing the researchers to discern which students were at the center of a particular school’s social web. Then they asked which classmates treated them aggressively, discounting playful teasing. The surveys showed that the students from whom the spokes of school popularity emanated were less likely to harass classmates verbally, spread rumors, engage in cyber-bullying, or use physical violence against their peers.
“Our interpretation is, kids view this as a means to an end. Once they get to the top, they no longer need to be aggressive. Aggression could be counterproductive: It could signal insecurity,” Mr. Faris said.
But, he added, “there are definitely some kids who were socially marginal and highly aggressive. There’s always going to be exceptions.”
The researchers, whose longitudinal study followed 3,722 students from 2002 through 2005, found that regardless of their backgrounds, race or ethnicity, or grade levels, the patterns of aggressors’ places in the social spectrum were the same.
“Traditionally, sociologists find these socioeconomic and demographic factors are the strongest predictors” of social behavior Mr. Faris said. “This is an exception.”

Born of Experience

He said the research was sparked, in part, by his own experiences as the victim of aggression.
“I’ve always had an interest in general terms in the relationship between power and violence. On a more personal level, in 4th grade, I used to come home with a bloody nose almost every day,” he said.
Two older students sought out the future sociologist, regardless of whether he changed bus stops or went out of his way to avoid them, looking to beat him up. He never knew why he was their frequent target. “I remember it being kind of a mystery.”
Mr. Faris and Ms. Felmlee’s findings jibe with what bullying-prevention and -support groups have found: Old stereotypes of school bullies are dangerous in the modern world.
RELATED BLOG
J. Marlene Snyder, the director of development for the Olweus Bullying Prevention Program, said her organization’s training makes clear that school employees shouldn’t have preconceived ideas about who might be aggressive at school.
“We are very careful to teach our teachers that anyone can play any role. It’s what group you’re with and what the situation is,” she said.
The Olweus approach is used in more than 7,000 schools nationwide and is named after a Norwegian researcher who began studying bullying behavior in his country more than 40 years ago. In the United States, Ms. Snyder and the Olweus program are based at Clemson University in South Carolina.
“We have been very careful in our training not to spend too much time on who might be the aggressor or who might be the child who is being victimized,” Ms. Snyder said. “Some of the early stuff [in bullying prevention] talked about personal characteristics. You can be pretty. You can be smart—anything that is different from the group—that someone in the group decides is not OK.’’
And from one moment to the next, one scenario to another, Ms. Snyder said students’ roles as aggressor and target may reverse.
“We do not use the terms ‘bully’ and ‘victim’. We’re trying to get people to understand that this is a very complex issue and not to just constantly saddle one child with one label,” she said. “That’s not helpful.”

Changing the Culture

At schools in Allegheny County, surrounding of Pittsburgh, Jim A. Bozigar employs the Olweus approach to combat aggression, whether the behavior is triggered by a desire for popularity or by teenage sexuality—the latter of which he noted that Mr. Faris’ research did not directly address.
His work is supported by the Highmark Healthy High 5, a five-year, $100 million initiative of the Highmark Foundation in Pittsburg to promote lifelong healthy behaviors in children and adolescents.
“If a child has any feature that can make them look or appear exceptional, that can make them a target,” Mr. Bozigar said. “The thing that we try to do is change the culture [of the school]. You have to empower the adults to empower students. They are the front line. They are the ones that are going to make the program succeed.”
What happened in the North Carolina schools Mr. Faris studied is also what Leigh Anne Kraemer, of The Ophelia Project, in Erie, Pa., has observed. The Ophelia Project is a nonprofit organization that works with youths and adults affected by relational and other nonphysical forms of aggression.
“It’s a myth that it’s just the popular kids that bully. It’s not the rich kids picking on the poor kids or the bigger ones picking on the little ones,” said Ms. Kraemer, the group’s education specialist. “If you’re looking to gain power and status by pushing others down, that’s where we really see a problem.”

Le IPad en classe

eaching With a Tablet: One Educator’s Experience


Lenny Gonzalez
Teacher Jeannetta Mitchell
For more detail about my visit to the Presidio Middle School’s iPad algebra class, here’s the complete Q&A with eighth-grade teacher Jeannetta Mitchell. She talks about the practicalities of forgoing the traditional textbook and seeing students find different ways of learning the material.
Far from being afraid of the technology — or believing that it will be the beacon of hope — this veteran teacher is a pragmatist. She’s determined to find the best way to grab her students’ interest and get them to enjoy learning.
Q. Do you think the iPad is actually changing the way students learn?
A. I definitely believe it’s changing the way they learn. The iPad is more than just a textbook. It has example videos to watch, so if I’m teaching in class and explaining something, they take notes. They think they understand, they go home, they might forget to do something or they’re not sure. They watch the video at home and it’s a teacher explaining the very same concept. So it’s like taking the teacher home with them.
It wasn’t the magic wand that was going to do everything for them, that they still had to think.
Given the fact that it’s on an iPad, they’re more apt to use it. Because the other students using print textbooks who have the same access to the videos online but who are not using iPads, they have to go to the computer and the Internet. And a kid doing homework at home, they’re not going to go to the computer, find the site, put in their user name and password. They’re not going to bother, because they think, “She’ll just explain it to me tomorrow.” But the kid with the iPad — it’s right there. All they have to do is hit a couple of buttons and watch the video. They’re more apt to use it.
Q. Where do they work out the problems?
A. On some of the pages on the iPad, there is a sketchpad … But I don’t think it can replace the pen and pencil; they’re still necessary for math. I want to see their work, because if the answer is incorrect, I need to see where they made the mistake.
Q. Do you allow them to use the calculator?
A. I don’t because these are numbers they should be comfortable with. If they use a calculator, they don’t get a sense of what makes sense and what doesn’t. I only let them use the calculator tocheck the work, not to do the work.
Q. How have their test scores measured up?
A. Initially, the test scores did not represent what everybody had hoped they would represent. The students performed actually at a lower level than my other three classes using print textbooks. And I had a conversation with the class explaining to them that the ipad was not the panacea of all ills. It wasn’t the magic wand that was going to do everything for them, that they still had to think. You have to be engaged. It’s not giving you the answers, it’s helping you get the answers.
But since I showed them the videos and they saw how helpful the videos were, they started using them. And I’ve noticed that the grades have gotten a lot better since I told them to use what’s available. You cannot convince any school, any district, to use this device if you’re not utilizing all the capabilities it has for you.
Q. Have the grades improved?
A. Yes. There’s not that big a discrepancy at all [between the classes that use the textbook and the iPad].  You would not be able to separate them between the classes. But I’m interested in seeing by the end of the year if it actually surpasses the others.
One of the things about the iPad, though, it’s a great tool, but it’s like anything, if you don’t use the tool you’re not going to get anything accomplished.
Q. Do you see the iPad helping with students who are having a hard time?
A. It helps the kid who wants to do well, but in middle school, it’s not going to magically make it happen for them. It’s not the magic wand. But if nothing else, it helps not carrying around a 10-pound book. But overall, the majority of the kids are using it for what it’s for. They’re taking advantage of what it can do.
One thing I do, I can provide multiple choice questions and their iPads will synch to my iPad and I’ll have [the answers] and they’ll have a timer. They do the work, and on my iPad, I can see how many kids are choosing which answers. The benefit for me is that if there are a number of people who are choosing one answer and it’s incorrect, it’s a quick cue for me to go back and see where’s the disconnect, what’s the problem. And it’s so immediate.
It’s different than saying, “How many of you don’t understand this,” or “How many of you got the wrong answer.” Kids aren’t going to hold up their hands to vote, but on their iPad, they know they’re somewhat anonymous. It just helps me.
It helps the kid who wants to do well, but in middle school, it’s not going to magically make it happen for them.
Q. Your students told me the iPads make math more fun.
A. It is fun! And we made it to where they can personalize it, and they’re allowed to get their music on it and things like that. But they also know that I have the capability of finding out every site that they’ve ever gone to, and not one child has gone on a site that they’re not supposed to.
But what’s great is that [principal] Pam Clisham has been really instrumental in getting the message to all the parents. They had to sign off on it. If anything happens they have to replace it, they have to buy insurance for it, and they have to know what sites [students] can’t use.
But the parents knew this was something big, and they wanted their child to participate. You have to get parents bought into it.
Q. At this point, do you think the iPad or the e-reader is just another passing fad, or will it really change what’s happening in schools?
A. I don’t think it’s a passing fad at all. When I look at students when they’re handed these big books, and a child looks at that fat book, they won’t say it verbally, they say it to themselves subconsciously, “I can’t learn that.” And I can see it on their faces.
With an iPad, they can look at it, they believe they’re going to learn what they have to from it because they don’t see the whole book. They see bits of information as it’s presented.
So I don’t get anyone who thinks, “I don’t get the first two chapters, I don’t get it, so I’m done.”
It’s a positive thing for them. Plus they don’t have a fear of anything electronic — they’re still showing me things — but they do have fear of a fat textbook.

Lenny Gonzalez
Q. What are some things you might change about this particular app for algebra?
A. We’re in contact weekly with Apple and the publishing company. They’re not saying, Here’s the perfect tool. Just take the test and we’ll take the results. They’re always asking what else can it do? That’s what I appreciate about it.
One thing that’s problematic is that the teacher’s edition is not on my iPad. Mine looks just like the students’, so I still have to use the big textbook. So hopefully they’ll have a teacher’s app.
And there needs to be a place for the kids to do the work. They’re working on how to reconfigure the sketchpad so it’s easier to use.
The supplementary pages are in the back of the book and are hard to find.
But what’s nice is they can make a note, either oral or type it in, to find something.
They also can record what I’m saying in class, and that happens more often than I thought. So when I’m talking, the kids can have record button on. It’s very clear what’s being said. They literally can take the teacher home with them. I have to make sure I know what I’m telling them.
And when they’re listening to something, or they want to make an oral note, they speak into the speaker it.
And they can add math apps. They can personalize it.
Q. As a teacher who’s now using the iPad in class, what do you say to those who fear it will replace them?
A. Anyone who thinks that the iPad or online textbook is going to replace them, they don’t have to worry about that. It’s just like giving a book to a student who reads well and telling them to teach themselves. That doesn’t happen.
Only the classroom teacher can see the disconnect, the child that has the question but isn’t asking. You have to be involved. I as a teacher cannot sit down while I’m teaching. That’s impossible. You have to move around and keep students engaged. There’s no doubt in my mind that if I left the room they would not be testing as well as they are. They need a teacher. So I don’t think that’s a problem.
Q. So how do you use the video tutorials?
A. Because how I teach might be different than what’s in the video, and the reality is that there’s more than one way to solve something. It doesn’t necessarily mimic me.
Ten years from now I don’t think they’re going to be carrying around these fat textbooks.
Q. Is the iPad helping students who are having a hard time?
A. I have students who are participating in this class who did not participate in their previous math classes. So it does engage them. Is it going to make them all brainiacs and straight A students? No, it’s not going to do that, but it will keep them engaged.
They’re interested. But at the same time I walk around making sure they’re doing what I want them to do, instead of some other applications. But that’s what a teacher does even when they have a textbook. Just like if they’re holding a cartoon book in front of their textbook.
I don’t believe the students think, “Well I won’t pay attention in class because I can watch it at home.”  That’s not the case. They really use it as a supplement, not as a replacement of the teacher.
Q. Do you think the iPad is motivating students to try harder?
A. Some of them are definitely trying more. “I had to watch it three times before I really got it, Ms. Mitchell.” And I say: “But how did you feel when you got it?” They say: “I understand it.”
I’ve never had a student say: “I’ve read this three times in the book, and I don’t get it, I’ll ask Ms. Mitchell tomorrow.” But they will watch that video.
But they don’t have to watch the video. They can see the problem and the iPad shows them the first step in solving it. So they go, ‘Oh, I can get it.’ Because many times you just need a boost, a reminder. And they pull down and see the next step, so it just introduces it a little at a time, it doesn’t just give the answer.
That’s one of the best things about the iPad as opposed to the book. It shows how to solve. The textbook just has answers in the back, no explanation as to how to get there. The iPad shows step by step how to get to it, so that’s the real plus.
Q. But is it solving the problem for them? Are they learning in that case?
A. They don’t really look at it as it’s solving the problem for them. They really want to understand. Kids really do want to learn, and this just makes it more fun for them to learn. Nobody’s just sitting there writing down the answer, saying, “I don’t know how I got there. They know how they got there.”
I don’t see anyone thinking that they got one over on the teacher because they got the answers off the machine.
Q. How have students been treating these expensive gadgets?
A. A week ago, none were lost or damaged. Now we have just one that’s missing. It was left somewhere that other people knew how to get to it. But the people who took it don’t realize we have a GPS on it. And the parents had bought insurance, but the replacement hasn’t come yet.
But mostly they’ve been really responsible. They give me iPads, I lock it up until class time, then I lock it until the end of the day when they come back for it.
Lenny Gonzalez
Q. What do you think is going to happen to textbooks in the future?
A. Ten years from now I don’t think they’re going to be carrying around these fat textbooks.
I can’t imagine that there won’t be a time that all the textbooks won’t be on the tablet. Students will be able to take it with them. If Houghton Mifflin Harcourt can put an algebra book on a tablet, what’s to stop them from putting a science book on the tablet? In fact, it might create even more consistency about which texts are more used in the district.
Q. What about cost?
Principal Pam Clisham, who was also in the room during the interview added her thoughts on the matter.
Pam Clisham: They’re expensive, but so are textbooks. If you had one iPad and all of your textbooks were on your iPad, it would be the same cost. Right now textbooks are running $50 or $60 dollars a piece, plus supplementary materials.
Jeannetta Mitchell: A student just needs one iPad for all of middle school. For a three-year period, it would pay for itself, and then some.

Les enseignants et la technologie

Bringing Teachers Onboard with Tech

Ed tech adoption isn't about forcing new technologies on teachers or wearing them down in an effort to obtain grudging "buy in." On the contrary. In order for any technology-centered education initiative to have meaningful results, according to Rushton Hurley, it has to be born of a spirit of collegiality, teamwork, and openness.
And, he said, it doesn't hurt to give teachers some time share their successes with one another.
Hurley heads up Next Vista for Learning, a project that provides free online media for educators and offers training on the use of video content in the classroom. He's also a frequent featured speaker on topics related to issues in education technology. Next week he'll be presenting at the FETC 2011 conference in a session focusing on technology adoption among teachers.
David Nagel: There's resistance from some teachers when it comes to technology adoption. How much of that has to do with the ways administrators and IT staff approach teachers?

Rushton Hurley argues that any meaningful technology initiative in a school is going to happen "in the teacher's heart first."
Rushton Hurley: Certainly some of this resistance is a function of leadership. The more top-down the approach to having teachers use technology, the greater the chance teachers will see it simply as a necessary minimum to meet or even an annoying requirement to avoid if possible. I believe that if something educationally meaningful is going to happen with technology, it happens in the teacher's heart first, and this is a function of seeing various possibilities, choosing those to pursue, and having time to explore with colleagues.
Nagel: You have a number of suggestions for getting teachers on board with technology. But what do you think is the top thing schools should stop doing right now and approach in a different way?
Hurley: I don't believe that technology sits apart from effectively addressing such things as teamwork and morale. I would suggest that those who lead staff meetings make time available on a regular basis for teachers to share the little things they are doing in very short chunks (one to three minutes), whether or not those things include technology. The idea is to get in front of the staff the creativity and successes happening all around them, and let that help them enjoy and celebrate the professionalism and talents of their colleagues.
It's wonderful to work with a staff for whom the dominant mode of communication is, rather than the complaints a vocal minority may be inflicting on the group, a celebration of exploring what's possible. Where I've seen this happen, the leadership communicates openly, finds time for teachers to work together, and can trust the staff to expect much of themselves.
Nagel: Sometimes the teachers who resist a particular technology initiative are right to resist it. How can they communicate that effectively, and what should administrators listen for?
Hurley: The key is what is happening with student learning. If a particular technology isn't or, given the circumstances, can't contribute to student success, then teachers and administrators have to take proper steps to identifying what would. This means working together to figure out if the issue is what the technology is or how it is being used. For the teacher, this means explaining what they are seeing (in detail and, ideally, with data) and being honest about the variables involved. For the administrator, this means focusing on how to help the teacher be successful and being honest about when the concerns are more about their commands rather than student learning.

Research Finds Text-Messaging Improves Children's Spelling Skills
