Open Educational Resources

no comments

What are they? They are part of the whole ‘open’ movement. So far I have mentioned open source, where a program developer or writer allows the source code (the blueprint, let’s say) of their program to be freely available for anyone to use or modify. Well, open educational resources (OER) adhere to the same ideals, they are resources for education – everything from whole courses to lesson plans, to handouts and more – that are made freely available by their creators or developers. All in all, very cool for educators!

If you want a snazzier definition, here is one from the OER Commons, found via Doug Belshaw and the OER infoKit:

Open Educational Resources (OER) are teaching and learning materials that are freely available online for everyone to use, whether you are an instructor, student or self-learner. Examples of OER include: full courses, course modules, syllabi, lectures, homework assignments, quizzes, lab and classroom activities, pedagogical materials, games, simulations, and many more resources contained in digital media collections from around the world.

The aim of the infoKit seems to be as a guide for people who want to be or who are involved in using OER. My personal favourite page is this one – the guide to finding OERs πŸ™‚

The OER infoKit is aimed at sites of higher education. There are OER for us in lower educational contexts πŸ˜‰ A future post will collect some information and links about those.

Gimp (open source programs I use)

no comments

Gimp is a free photoshop replacement.

Yup. Free as in no cost and Free as in Freedom.

It’s easy to add to Ubuntu through the Synaptic Package Manager that comes with Ubuntu (found in System=>Administration). It can also be downloaded and added manually for Linux, Windows, and Mac.

I have not used all of its features because I use it for basic photo enhancements (cropping, adjusting levels, resizing, setting filters…) and for creating images to be used for icons, banners, etc… It’s easy to learn to use, pretty intuitive and when you need help, just click on help or look through the easy to navigate user manual, available in many languages.

Here are a list of some features, from the site:

Features and Capabilities

This is only a very quickly thrown together list of GIMP features. You can also have a look at the illustrated features overview.

* Painting
o Full suite of painting tools including Brush, Pencil, Airbrush, Clone, etc.
o Sub-pixel sampling for all paint tools for high quality anti-aliasing
o Extremely powerful gradient editor and blend tool
o Supports custom brushes and patterns

* System

o Tile based memory management so image size is limited only by available disk space
o Virtually unlimited number of images open at one time

* Advanced Manipulation
o Full alpha channel support
o Layers and channels
o Multiple Undo/Redo (limited only by diskspace)
o Editable text layers
o Transformation tools including rotate, scale, shear and flip
o Selection tools including rectangle, rounded rectangle, ellipse, free, fuzzy
o Foreground extraction tool
o Advanced path tool doing bezier and polygonal selections.
o Transformable paths, transformable selections.
o Quickmask to paint a selection.

* Extensible

o A Procedural Database for calling internal GIMP functions from external programs as in Script-fu
o Advanced scripting capabilities (Scheme, Python, Perl)
o Plug-ins which allow for the easy addition of new file formats and new effect filters
o Over 100 plug-ins already available

* Animation
o Load and save animations in a convenient frame-as-layer format
o MNG support
o Frame Navigator (in GAP, the GIMP Animation Package)
o Onion Skin (in GAP, the GIMP Animation Package)
o Bluebox (in GAP, the GIMP Animation Package)

* File Handling
o File formats supported include bmp, gif, jpeg, mng, pcx, pdf, png, ps, psd, svg, tiff, tga, xpm, and many others
o Load, display, convert, save to many file formats
o SVG path import/export

* Much, much more!

OpenOffice (open source programs I use)

no comments

A big obstacle to switching from Windows or Mac to an operating system like Ubuntu is that you have to get used to new programs. It really isn’t a big obstacle though! There are so many options to choose from (which can admittedly be daunting) and Ubuntu has packaged the most popular and user friendly into their operating system.

For example.

Word Processing and other Office-y activities πŸ™‚

OpenOffice
Even when I was on Windows I began dabbling with Open Office but that was a few years ago and it wasn’t that great at the time. Now I get frustrated when I have to use Word because Open Office is so intuitive. It is also much more flexible, giving me the option to save a file in multiple formats (including .doc so that it can be opened on Word) and to open a file that was written in a different format (including docx, Vista’s file extension that can’t be opened by earlier versions of Word).

Ubuntu 10.04 comes with OpenOffice 3.2.
It’s an office suite so it is made up of

  • Writer – the word processor
  • Impress – the presentation creator
  • Calc – the spreadsheet application
  • Draw – to create and edit drawings, diagrams, etc…
  • Base – a database application

From the website:

Best of all, OpenOffice.org 3 can be downloaded and used entirely free of any licence fees. OpenOffice.org 3 is released under the LGPL licence. This means you may use it for any purpose – domestic, commercial, educational, public administration. You may install it on as many computers as you like. You may make copies and give them away to family, friends, students, employees – anyone you like.

Ubuntu in Education: benefits of open source in the classroom

3 comments

As you probably know by now, I use Ubuntu πŸ™‚ You can read about why I choose to use Ubuntu in my introductory post, for now I will focus on some of its benefits in educational settings.

No need to worry about outdated programs and compatibility issues

Compatibility Issues

One of the more frustrating aspects of teaching within a Microsoft world happened last year with the introduction of the docx file extension default in Windows Vista. As a way of getting customers to upgrade to (ie – buy) their new operating system, Microsoft created a brand new file extension for Vista that is not compatible with any earlier versions of Microsoft world. There is a way to save a document as a regular .doc document but most students just click save and the default gives them a docx. It’s so much fun when a student comes into class prepared to present a project or continue working on one they began at home and they can’t because none of the school machines can deal with docx documents.

There are ways around it – I’m sure zoho.com or google docs can open docx documents by now but one of the reasons why students still save their work to usb is because we can not always rely on the Internet being up and running in our classroom (admittedly that is improving – yay!).

The best way around it though is to have a teacher with OpenOffice on her laptop. OpenOffice is Ubuntu’s default Office-type program suite. OpenOffice can open all kinds of documents, including docx and pptx. So no worries. Heck, if you insist on using Windows you can still install OpenOffice. Won’t you feel better about using a program that has been built by a community, new versions can be upgraded free of charge because it is free and open source software, and is compatible with other programs?

Outdated programs

Programs don’t need to be outdated with Ubuntu. Ubuntu’s Update Manager, which comes with Ubuntu, notifies me of any software updates/upgrades that are available. Easy as pie. No need to purchase new software and go through removing the old and installing the new. My system does it for me and since I use free (as in freedom) and open source software, there is no need to purchase anything (or to have to think of any moral or criminal implications of illegal downloads).

Easy access to educational software

Ubuntu has a few different ways of finding out about and installing software. Two of the easiest ways are Synaptic Package Manager, which comes installed on Ubuntu, and Ubuntu Software Centre, also automatically included in Ubuntu for the past 2 releases. With both programs, you open them up, do a search for what you want (type in education and browse through the findings), find out more about it, then click install. The software automatically installs to your system in the right place (for example, if it is a video program you will be able to find it in the menu under ‘sound and video’, 9 times out of 10 there is no need to restart your computer in order for it to appear either).

Look how easy it is to find programs via Software Centre! (click on the image to actually be able to see it without a microscope)
Software Centre Home Screen

And this is what I get when I click on Education. Note that there is a scroll bar, there are many more below the bottom of the screen πŸ™‚ (again, click on the image to actually be able to see it without a microscope)
Software Centre Educational Software

Remember, all of these programs are free and open source. You are free to download them and use them and even tinker with the source code if you like in order to tweak them or create your own programs.

Edubuntu

Ubuntu also provides a complete operating system for educational purposes. Edubuntu can be installed on a school server.

Think of the financial implications of this –> there are no licensing fees. None.

Along with the no licensing fees (why more schools don’t use this I don’t know!) (Actually, I do know. Fear of linux.), you automatically have access to a plethora of free and open source educational programs that are included in the basic operating system. My school uses windows. Though our program (I work in an alternative program within the school) has a collection of its own mini-laptops. I am working on convincing our head teacher to allow me to play with Ubuntu on a few of the laptops, with a plan to gradually ubuntu-ize our program πŸ™‚

You can also install it directly on your own computer, without using the server version. If you look closely at the second image above (click on it to make it bigger) you will see this:

educational desktop for Ubuntu

Installing the educational desktop will give you a version of Ubuntu that automatically comes with educational software, without the need to add them on your own.

There are other benefits. Those are some to start. If you can think of some that I haven’t mentioned, please add them as comments for all of us to benefit from.

A short Ubuntu love story

5 comments

Last weekend I decided to test out a new operating system on my netbook (a Dell mini 9). I thought I would try out a completely free system, meaning that nothing on it would be proprietary – licensed for my use from a company that still maintains control over how I use it.

So I started by trying out gNewSense and then a few other systems – Puppy Linux, Xpud, Trisquel, ArkLinux, Damn Small Linux (dsl)

Installing Puppy Linux completely messed up my video card, it is touted as easy to install? No.
Xpud wasn’t bad – the wireless worked! Then I realized it wasn’t using free software…
DSL wasn’t bad, but certainly not intuitive, and there’s an issue with my wireless card that makes it irrelevant for my needs.
Trisquel just didn’t work, even as a live cd.
ArkLinux didn’t work at all. Couldn’t get past the boot loader. AND when I wrote to the address on their website for help I never received a response beyond the ‘we got your email you should hear from us in 24 hrs’ form letter.

gNewSense will most likely be the distribution I go for. It, like Xpud, also has wireless issues. Actually, it is my computer that has the issues – not gNewsense! The thing is, my Dell Mini 9 came with a Broadcom wireless card, it is a card that requires a proprietary driver so free systems don’t work out of the box with it. During the week, I found this article, which outlines how I may possibly get the wireless to work through gNewSense. I’m crossing my fingers it will work.

I imagine that gNewSense was so easy to install because it is created on Ubuntu. It is basically Ubuntu with no access to non-free stuff.

Here is where my love story starts. After all of the frustrations of downloading operating systems, creating an installer disk, trying to install with no success for 2 days and THEN having Puppy Linux (or my misguided attempts at installing it through their vague installation guidelines) go completely wacko, I decided to install a copy of Ubuntu Netbook Remix to try to clean up my system a bit. It installed like a charm in under 10 minutes.

I love Ubuntu.

What I may do, if gNewSense doesn’t pan out for me, is try to use Ubuntu without enabling any of the non-free repositories (the places from where you can download software, programs, drivers, and such). I’ll probably still end up with the wireless card issue. Hmmm. Any ideas on how to solve this?

Open Source & Education

no comments

One of the reasons I am so drawn to Ubuntu and an open source philosophy is that it reflects my own philosophy of education. That learning is a shared experience, it is collaborative and it happens in relationship. Because of that it makes sense for me to use Ubuntu and open source software as opposed to other operating systems and software that are not collaborative.

In open source, people who develop software and programs allow and expect other people to see the code that was used to create them as well as to make changes to it.

Anyone can use open source program code to make their own ‘new’ programs or just to tweak it to be more to their liking.

With companies like Microsoft and Apple, they don’t allow access to their program code precisely because they don’t want people to make their own programs based on it. If the code for itunes was made publicly available then Apple’s fear is that they will make less money as others began to make itunes-like applications.

Open resources are free, of course donations are always welcome :). This makes technology resources more accessible to more people, thus leveling the playing field for students and schools with different access to funding. If you are teaching a photography class you do not need to spend hundreds, even thousands of dollars on obtaining site licenses for programs like photoshop. You can get similar programs for free. I use the GIMP. Heck, if you want you can even challenge your students to download the GIMP source code and try to make it better! Talk about being creative!

In my classroom I encourage sharing, borrowing, creating, supporting, collaborating, and questioning. All aspects of open source philosophy. So it makes sense for me to use open resources in my classroom, in my home.

But what does that look like?

The next few posts will be about answering that question:

In the meantime, take a look at these sites to learn more about open resources and education.

Ubuntu is not scary

no comments

Really. It isn’t.

Especially now, this latest version of the Ubuntu operating system (known as the latest ‘release’) was so simple to install. It took barely a few minutes and I was good to go. AND that was with a development version, meaning it isn’t even the full release! There have been times in the past where a lot of tweaking had to be done to make things work but with each release that has improved and so far I have had to do no tweaking to make this one work for me. None. It’s working right out of the box. Amazing.

The full release is scheduled for the end of April, 2010. Ubuntu always names its releases after when it is released. So this one will be known as Ubuntu 10.04 aka Lucid Lynx. The previous version was Ubuntu 9.10 aka Karmic Koala, which was released in October, 2009.

My mission with this website is twofold:

1) to dispute the argument that Ubuntu is too difficult to use compared to the alternatives. If I can figure it out, anyone can!

2) to help others by sharing how I use and learn about Ubuntu and other open source projects.

Read on if you care about my own story with Ubuntu…
I started with Ubuntu in February of 2007 and haven’t looked back. Really. At first I was very lucky to have friends like Cyrille (in French) and John who helped me understand the things I didn’t. And of course I spent a lot of time on the Ubuntu Forums finding solutions to my questions. I was amazed at how the Ubuntu community immediately stepped up to help someone they didn’t know. And that is where I discovered the true value of Ubuntu. Not only is it an operating system that I trust to work how and when I want it, but I believe in what it stands for, its philosophy.

Ubuntu is an African word meaning ‘Humanity to others’, or ‘I am what I am because of who we all are’. The Ubuntu distribution brings the spirit of Ubuntu to the software world.
