One to One Computing: A Daydream

I closed the cover of my Chromebook, tucked it into my backpack and headed off to English class. I skipped lunch today so I had time to see the MIT lecture on Mitosis and Miosis because we were going to be covering Mitosis and Miosis in Science class this afternoon. Never hurts to get a head start.

Lucky for me, Mrs. Woodruff’s class was just around the corner from the cafeteria where lunch was just finishing up. Anyway, I wanted to get there early to ‘text’ Jamie Milledge, who was helping me build out my “Fahrenheit 451” wiki.

farneheit_451.jpgJamie would be up by now. I live on the East coast and she goes to school in Torrence, California. She is a major Ray Bradbury fan. We met up about a month ago when I found some of her science fiction writing on the Fan Fiction web page. Turns out she is the same age and studying “451” in her English class the same as me. We FaceBook each other all the time now.

I get to class and whip out my computer.

Jamie wassup?
Getting dressed.
Did you find the movie?
Yeah. Not easy to get.
Great.
What part do we want to use?
I love the RR tracks scene.
Where they all become their favorite books?
Yeah. So cool!
OK. I’ll upload it at lunch today.
You’re the best.

We chat until the class is ready to start.

Mrs. Woodruff is already leaning over a student helping them with whatever project they’re working on.

Last night I searched out some blogs that deal with “451″ and have added them to the RSS feeds in my aggregator. They may come in handy as we go through the book.

“Okay class, you can get into your teams now.”

Mrs. Woodruff speaks over the discussions that have already begun. I don’t know why she feels she has to say this every day because we never wait for her. We’re already in our groups.

Our group project is to build out a vocabulary blog for “451” . We each take a few chapters, find the more difficult words, and look them up online. Usually, when we do this we create a team blog where we post the sentence from the book that contains the word, as well as the definitions of the words. We organize it all by chapter. Here’s the vocabulary blog we did on our last book, “The Outsiders”.

This time, in addition to what we usually do, we decide to add some online photos from Flickr, drag them in Comic Life, and write the words used in funny contexts. Michael, our team leader, is really good at coming up with the funny stuff.

After a bit, Mrs. Woodruff asks us to close our computers and report out on how we are doing. One group has done research on all the books that have been banned over the years. Marcy plugs into the projector and shows the Censorship website they’ve created. They’ve worked with the school library media specialist, and a number of outside organizations who are very anti-censorship. I’m surprised at some of the titles on the list. I copy the URL. I want to check it out when I get to study hall later today.

The other groups plug in to show their particular projects; but Terry’s group gets into trouble because they havn’t done much since the last time they presented. Terry says that they have been doing a lot of the work after school; but they havn’t had an online work session this week because a few of them had late sports practices. Terry’s team always has an excuse. The truth is they put in no effort. They do what they can during free time in school, but they almost never hold group work sessions at night. They’ve got to get themselves a better leader or they’re gonna get creamed at the end of the marking period.

I can’t wait to show the vocabulary site we created. Everyone laughs at Michael’s funny comments that are in the Comic Life bubbles. I also take a moment to show the “451” wiki site that Jamie from California and I have been working on. Believe it or not, Jamie has already uploaded a scene from the movie. I click on it and play a minute or so.

Mrs. Woodruff claps her hands, “Great job! guys. Now, let’s get to our writing projects.”

We all pull our desks back a few feet from the groups we were in so we can work on our own for awhile. I pull up the draft of the paper I have been writing from my virtual locker storage space. I’m working on an essay topic from an old Regents exam. I figure it’s good practice. We write in silence, saving frequently, as we have been taught to do. Mrs. Woodruff walks around giving some individual advice to different folks. I run my paper through the online Writing Evaluator. I like this because it picks up most of the simple mistakes I tend to make when I write. It saves Mrs. Woodruff some time, too.

“Class!” She says. We all look up. She walks to the SmartBoard in the front of the room and taps on it a few times. Up come the notes from last week. She enlarges the words THEME and PLOT.

“I see a number of you are getting theme and plot confused. What is the difference between the theme and plot?”

A few brave souls raise their hands.

“You know what? Rather than doing this verbally, I want you to e-mail me your explanations for homework tonight. Include the basic theme of “451” . I don’t need you to rehash the plot.”

Man, more homework.

Mrs. Woodruff continued, “We’re getting close to the bell, so just a reminder that I will be online for extra help on Thursday from 8:00pm till 9:00pm. Terry, I expect that at least one member of your team should be there. Your team needs lot’s of help.”

The bell rings. I sling my Asus into my backpack and dash out of the room. My science class is at the other end of the building; I’ve gotta hustle.

This is a Re-Post from 2008.

It is a daydream. I’m sure there are many more creative ideas out there. The Asus and other products used in this post are for illustrative purposes only and not an endorsement.

The technology is transparent. The Asus is one of a number of sub-$500, mobile, wireless computers. WIreless access from everywhere in the school. VIrtualized desktops with access to all school applications and files from anywhere, including the home. Appropriate software. Engaged and empowered students AND teachers, learning both in school and outside of school, formally and informally, collaboratively and individually. Learning partners that extend outside the classroom.

Special thanks to Tom Woodward and Jim Coe, two groundbreaking educators from the Henrico schools who are making the daydream reality.

Two Roadblocks to Transformation We Have Yet to Address

Hundreds of educational technology bloggers and conference speakers hold forth on the need for transformational change in our educational system, and the conversation can get pretty lofty and philosophical.

I am a strong advocate for transformational reform; but it seems to me there are two very serious roadblocks in our way that we have yet to address.

The first roadblock is our school structure:

How does a Middle School or High School teacher use technology to create a student-centered, project-based learning classroom environment, when they have less than 45 minutes with their students per day?

BTW, they  must use these precious minutes to meet demanding state NCLB standards, and their curriculum may be governed by detailed ‘maps’ that outline the pace and sequence of teaching and learning in their classrooms.

Maybe the teacher does their best to squeeze in a project or two for the students during the year; but that doesn’t significantly change the primary classroom dynamic that is presently dominating secondary education.

The second roadblock is our technology deployment practices:

How does a Middle School or High School teacher use technology to move to student-centered, project-based learning, when they generally have only one or two computers, and maybe an interactive whiteboard and projector in their classrooms?

Maybe the teacher has a student use the interactive whiteboard while the rest of the class sits and watches, maybe the class watches a good video clip, or simulation; but the one computer classroom is a passive one and does not fully utilize the potential of technology to empower each individual student.

Unless we fully address these two basic questions, our best PD and transformational change efforts will make little impact on what is really going on in our schools.

Going ‘Green’ Saves Money

When I am asked to help districts save money or financially justify the paradigm shift to One to One computing, I suggest they audit their technology energy use. Shifting from traditional desktop PC’s to laptops, netbooks, or thin clients can save significant amounts of money, to say nothing of it being the environmentally correct thing to do.

A typical desktop computer uses between 65w-250w of electricity. A typical CRT monitor uses 80w and LCD 35w of electricity. You can get the actual amount of energy usage by checking the label on the specific device, or you can use a watt-meter to measure real energy consumption.

So, if we use 158w as an average for desktops and 58w as an average for monitors our total energy use is 216w per computer.

Let’s compute the energy cost of running just ONE computer for a typical school year.

Assumptions:

1. The computer is in use 6hrs per day. (6hrs x 216w = 1296w)

2. The computer is left in power saver mode over night. (18hrs x 35w = 630w)

3. The computer is in use 200 days per year. (200 days x (1296w+630w) = 385,000w)

4. The computer is in power saver mode on weekends and holidays, approximately 100 days. (24hrs x 35w = 840w) x 100 days = 84,000w)

5. The computer uses no energy 65 days of the year.

Total yearly energy cost for ONE computer is 469,000w or 469 kilowatt hrs.

Estimated yearly cost for ONE computer @ .17 per kw hour = $80.

Energy cost for ONE computer over a (5) year lifespan = $400.

Total annual energy cost for ONE THOUSAND computers = $79,730.

Total energy cost of ONE THOUSAND computers over (5) years = $398,650.

Now, lets look at alternatives to the energy hungry desktop PC approach that is so prevalent in our schools today.

A laptop or netbook averages about 30w, most of it related to the display.

A thin client and display also averages about 30w.

Thus replacing a standard desktop with a laptop, netbook, or thin client device theoretically produces an 86% reduction in energy consumption.

Estimated yearly cost for ONE device @ .17 per kw hour = $11

(Savings =$69)

Energy cost of ONE device over a (5) year lifespan = $55

(Savings =$345)

Total annual energy cost of ONE THOUSAND computers = $11,000

(Savings=$68,530)

Total energy cost of ONE THOUSAND computers over (5) years = $56,000

(Savings=$342,650)

Even if we take the ‘best case’ desktop scenario: a 65w computer and 35w display, the energy savings for shifting to laptop, netbook, or thin client devices is 54% resulting in a savings of $227,230.

In One to One implementations, if students use battery power during the day and are required to charge their devices at home, the energy savings can be more than 95% and a cost savings of $378,717.

The yearly $68,530 savings in energy costs (ONE THOUSAND computers) can purchase:

An additional (228) netbooks, or thin clients per year. (@$300 per device)

Over (5) years a school can DOUBLE the number of devices available to students (1140) based on energy savings generated by switching to netbooks or thin clients.

If you are more interested in the traditional route you can purchase laptops and add an additional (86) devices per year (@$800 per laptop) and increase your network by (430) devices over (5) years.

Anyway you look at it there is a good case to be made to go “Green”.

It’s time to shift our technology energy paradigm.

Should I Be Thinking About Moving to a One to One Model?

Without thinking about it consciously many of us change the emphasis of this question to make it a financial one that sounds like this: “Can I afford to go to a One to One model?” Our answer is generally, “No, I can barely afford the technology I have today!” When we think like this we believe we are being ‘realists’; but looking at educational technology this way shuts down many possibilities before we’ve fully explored them.

I like the approach that Bernajean Porter espouses:

Reality is too confining. If we are going to transform education, we need to let go of “reality”. If it is worth doing, then let’s do it. We should say “Yes!” first, then deal with questions of “How?” afterReality is too confining. If we are going to transform education, we need to let go of “reality”. If it is worth doing, then let’s do it. We should say “Yes!” first, then deal with questions of “How?” after.

If we keep deploying technology in the same ways we have for years, it seems to me, we are bound to continue getting the same results. It’s time for a new approach. One that puts technology in the hands of teachers and students so that they can move beyond the ‘many watching one’ model…

many watching one

….and ‘shared pencil’ approach that has dominated our classroom-based technology paradigms for decades.

girl boy sharing

How can we move to One to One financially? technically? pedagogically? There are lot’s of strategies to explore. There is no One Perfect Way to travel this path. In just the last two years the emergence of low-cost Netbooks,  Smartphones, new wireless standards, and  the availability of broadband in the home have made the initial cost of One to One more affordable.

In addition, Cloud Computing, virtualization, blade servers, and other new technologies have made One to One more easy to manage. All in all, One to One is more accessible to the average school district than at any time in the last 30 years.

Many visionary districts have found the answers to their questions and have created dynamic new One to One environments for learning. Many are beginning the journey with a single grade level or a single pilot. If you aren’t exploring and plannng for One to One, you should be.

It all starts with saying,”Yes!”

K-12 Cloud Computing: The Private Cloud

605px-Cloud_computing.svg

Cloud computing is getting a lot of play in the k-12 community and there’s no doubt that there are some wonderful benefits to this model for schools.

Web-based software can be the road to 24×7 access from any location with Internet access.

Software as a service off-loads the costs of servers and the ongoing cost of maintaining them by an already overburdened tech support staff.

Web-based software gets updated centrally and insures that all students and teachers are using the same version.

However, there are some limitations to the public cloud:

Not all applications run in the public cloud.

Storage of sensitive student data is not under the complete control of the school district.

Software becomes an annual subscription and not an outright, one-time purchase. Over time, software budgets will grow as we add more subscriptions.

We still need the local network for policies, printing, grouping students, web filtering, and local storage

We can address these issues by developing ‘private clouds’ within the district.

350px-Cloud_computing_types.svg

We can virtualize desktops and applications and run them from servers in the ‘private cloud’ so that little or no software remains on the students’ or teachers’ computing device. Combining Public and Private clouds provides the best of all world’s:

All the benefits of the public cloud as stated above…

plus

The school can run applications that are unique to their environment.

Access these applications 24×7 from any device with Internet access.

Become device independent (apps are running on servers) thus allowing the purchase of thin clients, netbooks, and other low cost computing devices.

Install and manage applications centrally.

Slow the replacement cycle (software runs on servers so no need to buy new computers every few years.

There is no doubt that we are at a unique crossroads in educational technology. There are huge changes in the ed tech paradigm that are about to take place. The Public and Private clouds are a means to an end and not the end itself.

As we shift to this new paradigm we also make it possible for each student to have their own device and to access their learning resources and files from anywhere, at any time.

Virtualization, Thin Clients, and Energy Consumption

In previous posts I documented a financial strategy that allows the average district to afford ubiquitous and/or one-to-one computing. This week I want to broaden the strategy to energy savings. It’s amazing what a significant savings replacing traditional ‘fat clients’ with ‘thin clients’ can be.

The University of Pennsylvania produced the energy graph below which shows the average PC drawing more than 100 watts during moderate use. This doesn’t include the monitor which on average can draw approximately 75 watts. So, for the sake of today’s post, let’s settle on 175 watts for the average energy use of a typical desktop used in our schools.

penn-u-energy-chart

Below is another chart, from the Mr. Electricity blog, showing ranges of PC energy use.

energy-use-chart

The chart below, from Steve Greenburg, President of Thin Client Solutions, shows the average energy used by several models of WYSE Thin Clients. The 3630 model uses more energy because it has a built in monitor. The other energy readings are without monitors.

thin-client-power-usage

From the same report, notice that the amount of energy consumed by Thin Clients is significantly less compared to the traditional PC.

thin-client-v-pc-graph

What kind of savings can we expect by implementing a Thin Client solution? Let’s look at a district with 1,000 computers.

Assumptions:

1. 175 watts used by each computer.

2. Each computer in moderate use 6 hours per day; 185 days per year.

3. Computers left on overnight and during the summer use approximately 35 watts.

4. The Thin Client solution uses 6 watts plus 75 watts for the monitor.

5. A utility rate of $.14 per kilowatt hour

Using these assumptions, the total amount spent on energy for our 1,000 computers is $64,680.

Now, let’s do the same calculation with the Thin Client solution

The approximate savings by implementing Thin Clients for our 1,000 computer network is $29,291 per year; a 45% savings in energy costs.

The 5 year savings = $146,455

$146,455 can be used to purchase quite a few new $450 devices.

BTW, it’s not only cost effective; but the right thing to do for our environment
