iPads vs. Chromebooks in Elementary School Classrooms

January 22nd, 2012 2 comments

This past week Apple introduced electronic textbooks through their iBook store and available in the iTunes University (iTunes U). iTunes U had previously been available only to higher education institutions. It is now available for K-12.. Also a part of the announcement was the introduction of a new iBook / Textbook authoring tool called iBook Author. With textbook publishers like Pearson “signed up” to populate the offerings, Apple is getting serious about getting electronic textbooks in the classroom.

Over the last day or so I’ve been using the iBook Author application to convert an ebook I wrote on church websites. I am fairly impressed with the tool and will blog a review of it in the near future. There is great potential for paper textbooks to be replaced with these very interactive and engaging products. Almost makes me want to go back to school.

Those of you that follow this blog know that I recently finished a series on Google Chromebooks in the classroom. So if an elementary school administrator is looking to “go digital” do you go with Chromebooks or iPads? By the way, iBook textbooks can only be used on iPads. Right now I’d have to lean toward Chromebooks for the following five reasons:

1. Chromebooks can be shared, while iPads are meant to be owned and operated by one student. I suppose you could share an iPad but the students couldn’t take their own notes, do anything customized for themselves or store documents/homework locally. One of the Chromebooks greatest strength is any student could pick up any Chromebook, login and start working. Since Google Apps is cloud based all documents, etc. are not stored on the local device…making the device just a vehicle to get at cloud based content.

2. iPads have limited storage. If you put five 2Gb textbooks on one (depending on the version of the iPad), you’ve used over half the available space. Chromebooks aren’t meant to have onboard storage, thus everything needs to be in the cloud. I think a smarter model for textbooks rather than chained to a device.

3. IPads are expensive. The lowest price model currently costs $499. To ask each child to own one at the elementary or even high school level is a tough sell. Chromebooks come with a monthly fee ($20/month) a school or parent can pay over time, and then if desired “own” the device after three years. Schools could do the same with iPads and cover the initial cost, but that is a large capital cost for most schools.

4. Google Apps have an excellent management console which allows very granular control over each device. iPads aren’t set up that way. Each has to be individually managed and don’t provide a lot of tools that allow them to be locked down.

5. Google Apps provides an ecosystem of Docs, Email, Groups, Sites, etc. that a classroom can use to provide needed services for homework submission, collaboration, and communications. The iPad environment can offer some services like that, but not nearly as cohesive or seamless.

Having said all that I do have to say that the interactive textbook experience offered by iBooks has great possibilities. What is available on Chromebooks right now isn’t as advanced. However, since the Chromebook relies on the web, any publisher or person who would want to create one could.

It should be interesting to watch how all this shakes out.

Chromebooks For The Classroom – Back To 7th Grade

October 20th, 2011 2 comments

As I write this post I’m sitting in the back of the 7th and 8th grade classroom of Grace Lutheran School in Oshkosh, WI. Many thanks to the students there and Principal Peter Iles for allowing me to spend a morning with them to observe their use of Chromebooks. After their initial envy of my white Chromebook vs. their apparently boring black ones, they went about their studies as if I wasn’t there. A great environment to watch students, and teacher, use the technology.

Currently the students are spending some time with their Chromebooks using KhanAcademy to practice math exercises. Very engaged. Very smooth. Principal Isles plays music while the kids work and shows the Khan Class Statistics on the screen in the front, displaying a line chart of classroom performance as they answer questions on their screens.

Grace Lutheran School has about 130 students. The 7th and 8th grade has 16 students. They were the very first elementary school in the country to introduce Chromebooks into the classroom. They have had a number of visitors so far this school year interested in watching their progress including the area newspaper. Of course, Google is very interested in their experience as well. Principal Iles was invited to Chicago recently to share his experience with education technologists and teachers.

As they started math class, the students were instructed to get their Chromebooks from a wheeled cart in the back of the room with slots for each laptop with a powercord attached. The whole process took about 2 minutes, and another 30 seconds later the kids had opened their Chromebooks, logged in and were working. Zero disruption to the educational process. Very important and impressive. The “instant on” nature of a Chromebook makes it a much better startup experience versus other more traditional netbooks some classrooms are trying.

The students seem to be very at home with the Chromebooks. Some use a mouse, others just the trackpad. All seem to be fairly proficient at the keyboard. Gone are the day when later years of grade school are spent in Mavis Typing Tutor to get the hang of a QWERTY keyboard. They still have “typing” practice, but not many use the hunt and peck approach I remember. They still also have a paper and pencil handy for scratching out math problems, etc, so it helps that their desks are about 2.5 feet wide. That will be something to consider in whatever computing device you want to place on the students desks. When classroom activities don’t include the Chromebooks (but they might be used later), the students are asked to close the lids. None of the students seem to be distracted by their presence. Just another tool at this point…like a textbook. Very natural.

There is very little technical infrastructure at the school. Basically they have internet access distributed throughout the school via wireless routers. No large file servers or other enterprise level network gear. Content filtering is provided through OpenDNS which Principal Iles manages by simply opening and blocking sites as necessary. They use the free version of OpenDNS and so far it has been meeting their needs. Most of our elementary schools are going to be in the same boat. The person in charge of technology is usually a full time teacher, so time spent administrating a network with proxy servers, content filters, domain servers and active directory management is not in the cards.

Principal Iles did relate that a couple of days ago a student came to him with a Chromebook that clearly had issues. After trying to work with it, he decided just to wipe it, restore the OS and re-enroll the machine on their Google Apps domain. Presto. Problem solved. BTW, that whole process takes about 5 minutes. All the apps, etc. are restored along with. No further configuration or installations necessary.

Note: Thanks for the cookie (I’m talking a real one here) from the young lady celebrating a birthday!

The students are now in the midst of History class. Principal Iles asked them to open their Chromebooks and then use the “Cornell Notes” template from Google Docs. He has assigned a specific naming convention for their notes (i.e. 20-1), so they can all “be on the same page” when referring to their notes related to a specific class and topic. Again, the entire process from sit down to start note taking was about 30 seconds. Toward the end of the class each student was asked to write a lesson summary.

The teacher doesn’t share his PowerPoints currently, but is considering using the new and improved Google Presentations tool, which he would then share with the students. He tries to keep the slides fairly simple, which then encourages the students not just to type everything they see on screen, but also listen for important points and type those into their notes.

Now the students have “computer class” which starts with touch typing practice using a free app called Touch Typing Tutorial from Typing Club.com. This is still important to speed/optimize note taking and paper writing. Principal Iles then went through a worksheet on Password Tips. A great idea to have class time devoted to essential computing best practices. The assignment is to create three “strong” and “weak” passwords that historical figures might have created (i.e. Albert Einstein and Mark Twain). So Twain might have created Huckl3b3rryFinn (strong) and beckythatcher (weak). The students used their Chrombooks to search for and research historical figures. Wikipedia seems to be a popular resource. Nice mix of tech and history. Some of the kids came up with -!raccoonboyH<3boots!- and TrigrHapy3 (Davey Crockett and George Eastman respectively). Fun.

During their research one student stumbled on a site that had a video that was set to autoplay. She quickly stopped it, but I can imagine that happening quite often during surfing exercises. Just something to be aware of. BTW, the students do have headphones available if they want to play a video they find.

The students only use the Chromebooks while in class, but as most students have computers at home, they will have access to all their Google Apps files from their home computers. This prevents lost and damaged computers, but still allows anytime access to assignments, notes, etc. No need to allow access “into” the schools network. It’s all on Google Apps.

Principal Iles uses other tools to interact with his students including the built in email and even Google Talk/Chat to address questions from the kids. Over lunch with Peter I explored a number of other topics including printing, paying for the devices, the relationship with Google and many other topics that I’ll share in future posts.

For now, I’d like to again thank Principal Peter Iles and the students of his 7th and 8th grade classroom. You guys were great. I had a good time and learned a lot. Blessings on your continued use of Chromebooks and your growing in knowledge and faith!

Chromebooks For The Classroom (Web-Only Computing)

October 12th, 2011 No comments
This is my third post in my review of Google’s Chromebook offering specifically for educational use. I’m excited to do a site visit next week with a WELS classroom who is actually using them, but for now you will have to settle for my rather myopic review based on an isolated review. Today I want to focus on the more general concept of web-only computing. In other words, what are we giving up by using a computer that can only access web-based applications that run within a browser vs. the more traditional applications you can install on a local hard disk.

I am not ready to do a comparison of education applications that would normally be used in our schools. That will come later after I get a chance to survey some of our teachers. What I do want to do is to talk about some of the advantages of living “in the cloud.” My next post will address disadvantages. Here are three big advantages I see in a web-based model:

Advantage #1: Updates are typically free, immediate, and don’t require “installation”
If you ask any school technology coordinator what takes the most time in maintaining a fleet of computers, either netbooks or desktops in a lab, he/she will tell you installations and updates. Very few have networks and software that will keep things nice and tidy on multiple computers at once. And those that do will tell you that not all apps can be maintained with a “group policy” or other tools. Web apps, by their very nature, are whatever the web server is serving up that day, updates and all. Essentially someone else (the app maker) is handling your updates. By the way, the same can be said of the Operating System itself. Chrome OS is updated by Google on a very frequent bases, and no user interaction is needed. At the very most a quick restart of the machine is required – a 15 second exercise on the Chromebook.

Advantage #2: Web-based apps can run at the speed of the browser and web server, not the local hardware
In many of our schools, budgets are tight and technology budgets are even tighter. As a result the physical computers in the hands of the children are rarely speed demons. In my observations I see three to four year old hardware, at best, that has been either cobbled together or donated from a company that felt they were no longer suitable for use by their employees. Even those schools that have purchased netbooks have found that the underpowered, battery conserving processors struggle to run standard apps like Microsoft Office and other standard apps students might use. As a result students do a lot of waiting (and chatting and whatever) for their computer to do its thing — either to open an app or complete a command.

Web apps have been optimized to run in the browser and in most cases can complete tasks in a very acceptable time frame. One reason for that is that the processing power is taken care of by the web server, and the results of the command are simply “sent down” to the browser for viewing. You aren’t relying on the computing power of your own computer, but somebody else’s more powerful one.

Advantage #3: Security and backups are built in
Infrastructure to keep data (and students) safe and to make sure no data gets lost or corrupted can be expensive and time consuming. Content filters, server or machine-based antivirus apps, firewalls, and backup software (and the disk spaced needed to make them work) are all things that are essentially taken care of in a browser only world like Chrome OS. Cloud-based applications need to provide their own storage and backup solutions. They also handle the security of the user. Chrome OS handles virus protection, which becomes much simpler if no applications or files are ever downloaded to a hard drive. Really all a student needs is a browser and a login. They can work on any machine and the school can feel good about the safety of both the computer and it’s user. Of course, care still needs to be taken with what apps are allowed or websites visited (which can be controlled within Chrome OS).

There are other advantages which include the lower cost of web-based apps, the ease in making new apps available, and the ability to try-before-you-buy (or use) without a lot of fuss. However, there are also disadvantages. Stay tuned for those.

Chromebooks For The Classroom (Administration)

October 6th, 2011 No comments
This is my second post in a longer series where I am reviewing Google’s Chromebook and its suitability for our WELS classrooms. You can read my first article where I gave my first impressions and a review of the installation procedure. By the way, I’m typing all the posts for this series on a Chromebook so I can rate that experience as well. Last week I typed right into my WordPress interface. This week I’m starting by typing everything into a Google Doc and will then cut and paste into WordPress. I’ll let you know how that goes as well.

Today I wanted to talk about the administration of Chromebooks via the Google Apps tools. When you “enroll” a Chromebook into your Googel Apps domain it can be managed under the Chrome OS section of the administrative interface. This is the same place you manage users and the tools they will have access to. Here is a good article on how best to get up to speed on this control panel: http://www.google.com/support/a/bin/answer.py?answer=55955.

There are many things you can control for the Chromebook user, which does make this an appealing choice for the administrator in charge of managing these devices you have just put in the hands of children. I won’t go through all of the options, but will touch on just a few:

1. One of the best features is to take advantage of the sub-organizations you can create within the tool. I’d recommend that all users be put in different sub-organizations within your domain. For instance, you could have a sub org for each classroom. This will allow you to configure the Chromebooks applications, extensions, home page and other behavior for each individual classroom differently. So the 4th graders can have their own apps which would be different than the 8th graders. Very slick.

2. On the geekier side, you can set up a default proxy server that the Chromebooks will use. This will allow you to continue to use content filtering software, etc.

3. Perhaps the most useful configuration/administration tool is one that allows you to install apps and extensions. So you could provide a common set of apps for each student that would work well for that grade level. There are many apps available including those that are useful for teaching math, english, typing, etc. They, of course, are all web apps. I will say that the process for adding apps is a little cryptic. You need to add a line of code that looks something like this “oojbgadfejifecebmdnhhkbhdjaphole;https://clients2.google.com/service/update2/crx” separated by commas. The first part is the App ID from the Google Web Store. The https part is the location of the app (i.e. the Web Store). So you have to go into the Web Store first, grab the ID from within the URL and then plug it into the control panel. I’m assuming Google will improve this process in the future. It is ripe for user error. But once you get the hang of it, you can get any app or extension you want to appear on the users screen. And again, by Sub Organization. There is also a way to block or only allow the installation of apps/extensions you specify.

4. You can also specify what Search tool is used in the “Omnibox.” The Omnibox is the URL bar at the top of the browser that not only accepts web address, but will do searches on non-web addresses. By default, of course, its Google, but you can change it to Bing or any other engine of your choice including Goodsearch — my favorite, which will also donate a penny per search to the charity of your choice. Listen to our interview with one of the founders of Goodsearch on a recent WELSTech podcast.

Those are just a few of the config settings at the disposal of the Google Apps administrator. My overall impression is that they provide a “good start” for control. In the future, I hope they allow more “parental control” type features that will track web history and basic web and image filtering. Another nice feature would be the ability to “see” what is on the screen of any one student at any given time. This can be an invaluable tool for the teachers.

That’s it for this post. Next time I’ll begin to explore the advantages of a web app environment over a more traditional installed app approach.

Polishing Chrome

August 30th, 2011 No comments

google-chrome-logoI tend to use a few browsers in my professional and personal computing lives for many different reasons, but the one I prefer is Google Chrome – for basically three reasons. Chrome, at least in my experience, is faster. Chrome runs Gmail, Reader and the new Google+ better than the other browsers. And finally, Chrome offers just the right amount of customization to allow me to optimize my time in the browser, which is a lot. So I’d like to just highlight five ways I have customized Chrome to keep things efficient.

1. Set the start page to the Apps window. Many apps exist that can be placed on that screen, so for me it acts like a launcher. I can launch my email (Gmail), RSS reader (Google Reader), task manager (Remember The Milk), image editor (Picnic), and almost any other Web 2.0 application right from one screen. As an added bonus, I have access to my “Most visited” sites and “Recently closed” sites at the bottom.

To get the Apps window to show up first when launching Chrome, click on the wrench icon inrtm the upper right, select preferences and go to Basics on the left. Then make sure “Open the home page” is selected in the “On Startup” group and “Use the New Tab page” is selected in the Home Page Group. BTW, you can add your favorite Apps by clicking on the Web Store icon.

2. Always show your bookmarks bar. This will come in handy once we go through setup #3 below. This will allow you to have one or two click access to your bookmarks. If you don’t have an app on the Apps screen, you can nest all your favorite websites in your bookmarks. So when you click the star icon in the browser to set a bookmark, just be sure it is placed in a subfolder on your Bookmarks Bar.

To insure that the bar is always visible, again go to preferences (wrench icon) under Basics and select “Always show the bookmarks bar” under the Toolbar group. While you are therebar you might as well click the “Show Home button” so you can always show your Apps listing when you want. (see #1 above)

3. Now on to the cool extensions. Use Xmarks to keep your bookmarks in sync. Xmarks, now a part of LastPass (see #4 below) allows you to add and manage bookmarks in one browser and have them stay in sync on any other browser on any other computer where you have also starinstalled Xmarks. It’s free and works well.

To add extensions, click on the wrench icon one more time, click Tools, and then Extensions. Click the “Get more extensions >>” link at the bottom and search for Xmarks. Follow the instructions and you are on your way.

4. Install the LastPass extension. Many of us have and use more than one password. In fact, everybody should be diligent about varying their passwords from site to site. LastPass makes that easy. I’ve written about LastPass before, so I won’t go into detail here, but in short, it manages all your passwords and then fills them in to the appropriate fields on a website for you automatically. Just follow the same instructions as #3 above to get it installed. Just a note, it is worth the $12 a year to purchase the premium version.

5. Use Diigo. I’ve talked about Diigo before and find new uses for it each day. Diigo allows you to bookmark any site, annotate that site with notes or highlights, and then share that bookmark with otherpeople or groups of people, like your WELSTech friends. You don’t want every site you are interested in on your bookmarks bar (see #2 above). But you do want to be able to go back to and reference sites when needed. Diigo does much more than that of course. I couldn’t compute without it in this Web 2.0 world. Install the extension using the same directions as #3 above.

Well that’s it. You now have a pretty good picture of what fills my screen once Chrome is launched and I’m working on the web. It might improve your computing experience as well.

Control Your Google Reader Viewing Experience

June 12th, 2011 No comments

Google Reader is one of those tools that I touch everyday in my line of work. To stay current on technology and ministry topics means I need to read about trends, ideas, thoughts and what-not from hundreds of blogs and websites. Google Reader brings all that together for me in one easy-to-read digest. Right out of the box Google Reader provides a nice viewing experience, but with fairly easy to use tools, and an awesome add on, you can customize things to work exactly the way you want and increase your productivity in the process.

The sweet set of tools, available via an add on in the Chrome web store called Super Google Reader, are the reading tabs across the top of each post. This feature alone is worth switching to Chrome, as the add on isn’t available on other browsers. Since Google Reader makes both the Reader app and Chrome, the experience is much better when the two are used in combination. Once you have Chrome and the Super Google Reader add on installed you will see three tab views including Readable, Link, and Feed. Feed is the one you are probably most familiar with as it displays whatever the blog or web author wanted you to see with the feed including embedded ads, etc. The Readable and Feed tabs are a bit more interesting. By clicking on the Readable tab you get a stripped down version of just the relevant pictures and text. No ads or other materials that aren’t part of the article. Great view.

The Link feed is really just the opposite of Readable. It shows you everything – essentially the entire website which houses the article itself including the navigation, ads, videos, etc. Be careful with this tab as it may slow things down considerably as it loads all those assets.

 

Screen-shot-2011-05-31-at-4.31

 

If you click on Super settings… just above the tabs you can configure how you want those tabs to work, or which one is set as the default, or only one showing.

Another setting of note is the “Sort by magic” item in the View settings… menu. You don’t need Super Google Reader for this. It sounds a little bit like Google searches “I’m feeling lucky.” It has a similar purpose. The setting tries to predict what you are most interested in based on your previous activity with Reader. It remembers the kinds of feeds you add, what you “like” and what you “share” with others. Based on that it predicts the articles and associated feeds you might be most interested in reading.

I don’t keep it on all the time, but if I’ve been away from Reader for a few days, I could have over 1000 articles waiting for me to read. Yeah, right! Turning on “sort by magic” floats the likely articles of interest to the top. I read those and then use another handy button on the tool bar to give me a fresh start the next time I login – Mark all as read.

Finally, a nifty keyboard shortcut that is a must for every Google Reader reader. When moving from article to article be sure to use the J and K keys. J moves you forward one article, and K moves you back. A real time saver versus finding and clicking the Previous and Next Item buttons at the bottom of the screen every time.

Those are just a few of the settings within Google Reader that have the potential to boost productivity. Try a few of them out, and be sure to explore the Reader Settings screens for even more tweaks. Just click on the gear icon in the upper right of the screen.

Let me know how you use Google Reader and share some of your favorite features.

Is it good to be “in the clouds”?

April 7th, 2011 1 comment

cloudIt’s hard to use a computer and be on the internet these days without hearing about “the cloud.” The cloud is a term used to describe many things, but typically locations someplace other than where you and your computer are. Technically, the cloud is the internet and the many different servers that make it up. Functionally, the cloud is place that can hold your digital stuff.

There are many uses for the cloud, but in general cloud services that are popular today do two things: 1) Provide a place to backup your data, and 2) Provide a place to store and share your data. Both are valuable to the church and school office. Here are a list of the most popular services in each category.

Cloud-based backup services

  • Mozy – $5.99/month for Mozy Home (50Gb Storage for 1 computer), $9.99/month for Mozy Home (125Gb Storage for up to 3 computers), $3.95/month/per Desktop for Mozy Business (+ .50/Gb per month), $6.95/month/ per server for Mozy Business (+ .50/Gb per month).
  • Carbonite – $54.95/year for 1 year plan for one computer (internal hard drive backup only), $99.95/2 years, or $129.95/3 years. No storage limits.
  • Backblaze -  $50/year per computer. Unlimited externally connected drives and unlimited storage.

There are many other cloud based backup services out there, but these three are the leaders in my mind. I believe the best value is Backblaze due to the unlimited storage and allowance for externally connected drives.

Cloud-based storage and sharing services

  • Dropbox – syncs between computers and online storage with sharing capabilities, 2Gb storage free, 50Gb storage $99/year, 100Gb storage $199/year.
  • Box.net – all cloud-based storage, no offline syncing feature in free version, 5Gb storage free, $9.99/month for 25Gb, $19.99/month for 50Gb.
  • Windows Live Skydrive – all cloud-based storage, 25Gb storage free, no fee based additional storage available
  • Google Docs – all cloud-based storage shared with gmail (about 7 Gb right now), $5.00/year for 20Gb, $20/year for 80Gb, $50/year for 200Gb, up to $256/year for 1Tb.
  • Amazon Cloud Drive (recently launched) – all cloud-based storage, no syncing currently available, 5Gb storage for free, 20Gb if you purchase music from Amazon to store there, $20/year for 20Gb, $50/year for 50Gb, up to $1,000/year for 1Tb.
  • AVG LiveKive (recently launched) – allows syncing to local folders, $49.99/year for 25Gb, $79.99/year for unlimited storage.

Most all of these services allow mobile phone access and easy sharing of files with those who you select. All of them have their pluses and minuses and will like fit different needs. All of them also encrypt your files for security reasons.

If you have good or bad experiences with any of these services, please feel free to share. Personally I use BackBlaze, Dropbox and Google Docs on a fairly regular basis. Church and school offices may want to consider how these tools can help in both the backup and file sharing areas.
