Trey’s new home computer

One would think that researching and purchasing computers for the University would make it easier to purchase a computer to use at home.  For me this just isn’t the case.  For one thing I am cheap.  I start configuring a system with all the goodies I want, and I am suddenly looking at a computer that costs $1,700-2,500.  Ouch!  So I asked myself, what does this computer really need to do.  I want to:

  • check e-mail,
  • surf the Internet,
  • write,
  • work with numbers and presentations,
  • play music,
  • handle my digital photos, and that’s about it.

So here is what I did. I found a refurbished IBM Thinkpad at Tiger Direct for around $500.  The Thinkpad I chose is a lightweight laptop with a 14” screen, Pentium M processor, CD-RW/DVD, 1G RAM, a 60G hard drive, Windows XP Pro, and a 1 year warranty.  Not a power house, but solid, proven, and dependable performer.  Windows XP Pro ran well on the computer, but I decided to look into Linux.   Linux runs a computer just like Windows or the Mac operating system does (the Mac OS is a version of Unix just like Linux.)  Linux has been around for years, and has been considered an operating system for “computer geeks”.  Recent improvements to versions of the Linux operating system have made it more user friendly.  Many computer manufacturers are offering computers running the Linux operating system right next to Windows based computers these days. 

I talked with Chris Rutledge and Pat Riehecky in IT about the versions of Linux they like best.  They both were singing praises of Ubuntu Linux version 7.10.   I did some research, downloaded the free installer from http://www.ubuntu.com and burned it to a CD.  The Ubuntu distribution CD comes with Open Office for word processing, spreadsheets and presentations.  Open office works similarly to Microsoft Office and is compatible with Microsoft Office documents.  Also included are programs to edit, scan in, and view photos, listen to music and watch movies.  The Firefox web browser is included, as well as an instant messaging client, an e-mail client, several games, and many other goodies.  All the features I wanted for my new computer.  Another neat feature is that Ubuntu and the bundled applications are Open Source, in other words, available for free (I did mention that I am cheap).

The Ubuntu operating system is easy to use.  If a person has used Windows or the Mac operating system, they will have no problems using a computer running Ubuntu.  I am very happy with the computers performance.   Programs load and run very quickly.  My printer and digital camera installed very easily.  I plugged the devices in, the computer configured them in about 10 seconds and told me the devices are ready to use.  I have the e-mail client checking my IWU e-mail, and have consolidated all of my pictures on the computer.  So far the computer is perfect for my needs, and seems to find it’s way to my lap every evening.

I will post updates to my computer adventure as I discover new features and install new software.

backing up moves forward

Perhaps a device like this will solve the backup conundrum:

 http://fabrik.com/

 These are external hard drives that automatically sync a portion your backup to a server on their network. This provides easy offsite storage with the convenience of having a backup drive on your desk. The speed and reliability of the service remains to be seen, but this is a step in the right direction.

 Mac users who upgrade to OS X 10.5 have a similarly streamlined tool called Time Machine. This software automatically does incremental backups every hour, day and week. You can set the destination to an external drive or to an Apple Xserve server. I took a look at the Apple website but saw no indication that this software works with their .Mac network storage service. Perhaps in future versions Time Machine will allow mirrored backups to external disk and an internet-based network storage service…

easy ways to read internet news and blogs

Patrick and I were talking yesterday about the “types” of people who want to read news and blogs on the internet. Nearly everyone uses the web to go out and read articles, so even if they don’t know it they are gathering feed-based information. This most basic method of information hunting-and-gathering is just fine, but there might be another way that fits your personal work patterns better.

Here is the breakdown as I see it. People will tend to do one or more of the following:

  1. go out to multiple websites each day and read articles, columns, journals, and news on their own “home pages”
  2. use a web-based service (Bloglines, Google Reader) to collect, or aggregate, the information on a single web page
  3. use a program (like Thunderbird) to collect articles from favorite news sources and treat them like e-mail

I personally like getting my news alongside my e-mail using Mozilla Thunderbird. I check my e-mail quite frequently and tend to fall behind on reading my favorite websites. By getting a message every time a new article is posted, I can keep up with things better. This is solely a factor of the way I like to work, not a choice based on efficiency or “correctness.” 

We at IT expect other people feel the same way, so I’ve prepared a quick guide for any Thunderbird user who might want to try out gathering feeds in this way. Let me know if it helps!

We need your assistance.

Information Technology needs your help. We are working to make improvements to the e-mail system. As work is done to make these improvements, we are asking people to take a look at the messages they have saved to see if unwanted or large messages could be deleted from the e-mail server.

How to help

Log in to my.iwu.edu and access your e-mail

  1. Click on your Sent folder and take a look to see if any of these messages could be deleted – removing messages with attachments will help free up even more space
  2. Click on your Trash or Deleted mailbox – Delete any messages in this mailbox.
  3. Remove any old or unneeded messages from your Inbox. E-mails with pictures and presentations attached can take a large portion of e-mail storage space. Save the attachments to your computer and delete the corresponding message.

Thank you for your assistance.

If you have questions about forwarding or archiving your mail please call 556-3900.

picking the right web tool for the job

Choosing to use a technology tool in a class can lead one down a difficult road. One important key is to figure out what tool to use for the job at hand. So do you use discussion groups, a digital movie project, a wiki, or a blog? To analogize, I wouldn’t want to use a belt sander to grout my bathroom tile, so it would be nice to better understand the nature of these different tools.

So how does one decide what tool or is the best for a specific application or need?

 I’ve found a couple of helpful guides to better understand blogs and wikis in the context of teaching and active learning:

RefWorks Workshops at Ames Library

Managing online discussions

As we at Illinois Wesleyan struggle to adapt courses to include online or technology components it often seems that a square peg is being pounded into a round hole. Some parts of some courses are well suited to technology tools and some are not. Here are a few things to keep in mind:

  • Online resources can be accessed at any time, from any place, any number of times
  • Computers can deliver content at the student’s own pace

So it seems that some things can be done outside of classtime so we can get them “out of the way” to spend classtime on higher-level academic discourse. Why not teach basic terminology or vocabulary as online homework so you can tackle tougher stuff in person?

Similarly, if students are engaging in intellectual enterprises outside of class (such as writing critical responses to class reading) doesn’t that mean they benefit from the practice of constructing arguments, or even from the practice of writing in general?

Certainly there are benefits. But how does a teacher manage student activity in the online medium? Let me start with three common refrains from faculty:

  • “How do I get students to engage in frequent, quality online discussions?”
  • “How am I going to grade all that?”
  • “How am I even going to read all that??”

I attended a conference this month and heard an interesting response to these concerns. John Fritz, from the University of Maryland, Baltimore County uses a construct he calls “Participation Portfolios.” Here is his abstract:

If you want students to use online discussions, how do you avoid initiating every thread or simply counting all their replies? By defining and rewarding substantive Q&A (and requiring an online “participation portfolio”). Students will take responsibility for discussions and reduce your burden in assessing them.

John makes an important distinction between quantity of discussion and quality of discussion. This is something that he clearly sets out at the beginning of a course with a rubric. By setting clear guidelines of what makes a post or response “good”, “average”, or “poor” he eliminates “me-too” responses and also reduces grade-groveling later in the term. He requires posts and responses to be spread throughout the course, to stem the tendency to “dogpile” at the end of a term. And it cannot be ignored that John participates in the online discussion. This models the behavior he desires from his students, and sets the academic tone of the discussion.

The students are then asked to pull the best examples of “good” posts, week by week, from the online class discussion forum. They cut-and-paste them into a Word template, propose their own grade based on the rubric, and hand them in. John reserves the right to adjust the grades, but finds that most students are harder on themselves that he would have been.

This system of Participation Portfolios addresses a number of problems. It provides a for-credit incentive with clear quality guidelines for students . It reduces the workload on a faculty member by distilling a term’s worth of discussion into a single assignment. It also requires a student to evaluate their writing and assess themselves.

If you want to hear about how well the assignment works, watch this video interview with UMBC Professor Chris Swan about this portfolio assignment (opens in iTunes).

UMBC didn’t come up with this overnight. They have a program on their campus to promote Alternative Delivery of class content. Faculty design a online/hybrid learning module and test it twice – once for students and once for faculty. They then make a 10 minute presentation about their experience to earn a stipend.

I hope that by reviewing the best practices at some other institutions, such as the Portfolio that John Fritz proposes, we might ease the integration of technology into some of our own courses.

Outsourcing Moodle: a viable option?

Moodle is a leading open-source learning management system that is fast becoming a common alternative to Blackboard and WebCT on college campuses. While a free, open-source package sounds wonderful, it is never truly free. If Illinois Wesleyan decides to go with Moodle on our own, we have many costs. First, it would need to reside on a server with adequate storage and bandwidth. Second, we would need to integrate it with existing systems. Third, we would need to provide adequate resources to maintain the server and software, ensuring reliability and security. Fourth, we would need to provide training and support to our community. So, with a shortage of people and money, what to do?

Well, there are a number of firms that provide hosted Moodle solutions, some of which also provide integration services. Some will even train our staff to prepare us to work with users.

With that in mind, I’ve done a cursory look through some of the offerings. Again, the criteria are:

  1. Hosting (price, storage, bandwidth)
  2. Integration (price, Banner, Luminis portal)
  3. Support (maintenance agreement)
  4. Training

Here are the major players measured against the criteria above:

  • Remote Learner – adequate hosting for $1500 on up, server support for $2000-3500 annually which would probably include help with integration. It looks like we would be largely on our own for training – they have some affordable options but they are far away and limited in scope.
  • Moodle Rooms – adequate hosting for $1500 on up, with “customization” on a call-for-a-quote basis. They have done a Banner/Luminis integration project before. Training is expensive at $2500+ per class. 
  • Classroom Revolution – adequate hosting for $1299 on up. Support is limited without an additional contract ($60/hr or $800/year for online support). They will do “customization” but don’t note any experience with Banner/Luminis on their website. They do offer a more affordable online training option ($500) along with an expensive onsite one ($2000+).

Please remember that this is a quick summary based mostly on websites. When I say “adequate” hosting I mean generally “one notch above the minimum”, or something that we could start with and scale up a bit with no additional upcharge. Support and customization are an unknown quantity since I haven’t seen any Service Level Agreements from any of these firms.

backing up your data

I’ve worked with a number of individuals lately who are interested in fast, easy, comprehensive backup solutions. Let me begin by saying that this is a tall order indeed! The new wave of cheap, large external hard drives such as the Maxtor One-Touch line promise just that – a complete backup that requires only a second of a user’s time. I must insist that this scenario is too good to be true.

Here are the main things I want from a backup:

  • Cheap
  • Fast
  • Easy to recover files
  • Copies at offsite location 

So, how does an external hard drive stack up?

An incremental backup to an external device is nice, and could be invaluable if a laptop is dropped or stolen, a hard drive goes corrupt, or files are deleted. However if there is a fire, burglary, or flood it is likely that the external drive will be compromised as well as the original data source. External hard drives are no substitute for backups to removable media. I do NOT mean USB flash drives. They are too easily damaged, lost, or put through the laundry. 

What about CD-R or DVD-R?

 Until something faster comes along, I like frequent backups to optical media. Then some of the backup discs should be stored offsite (read: take your work backup home and vice versa). CD and DVD media are quite cheap and drives are getting quite fast.

So why don’t users typically sustain an offsite backup? There are tradeoffs involved. It certainly takes time and effort, but so does recreating hundreds of documents and e-mails from printed records. And what about digital photos? I personally have over 3 years of irreplaceable digital photos that do not exist in printed form. Because of the importance of this pictures, I pay for an online service to store my digital photo backup. Photos like this are worth every bit of time and effort it takes to periodically back up. Unfortunately most users don’t learn this lesson until it is too late.

Until such time as Illinois Wesleyan can afford to support large-scale centralized data storage with offsite backups our users will continue to be responsible for their own backups.  Whenever I’m asked my opinion I will continue to recommend a dual approach – onsite incremental backups to an external device, along with regular backups to removable media which go to offsite storage. I only hope the message gets through!

technology we are thinking about

I’d like to share with you a few things that we are checking out in the Office of IT. These aren’t things we are committed to at this stage but if you have an opinion I’d like to hear it!

  • Moodle, an open-source alternative to Blackboard or WebCT. Moodle provides a set of course tools that include wikis, online quizzes, and grade books.
  • RSS Feed readers like Bloglines, Google Reader, and Mozilla Thunderbird. Check out the great video explaining the meaning of RSS.
  • web meeting capability, using WebEx or Adobe Connect
  • Confluence, a wiki-based tool for managing shared online workspaces.
