Save space: Compress your audio files

Many researchers use interviews as a source of data collection. Whether it be one-on-one interviews or focus groups, it is common to record the session for review at a later time. Here in the Faculty of Education, many of you store these recordings on your work computer or on your personal space: a smart thing to do as these are backed up on a regular basis. If anything happens to your original files, they can be retrieved from the backup.

Raw digital audio files can be extremely large. These large files can quickly fill up your harddrive and significantly slow the backup process; and the longer it takes for files to be copied the more potential for failure. What is the solution? File compression.

Here are two examples of conversion software that may warrant further investigation:

(1) Switch Audio Converter (PC or Mac) http://www.nch.com.au/switch/ converts to mp3 format and is compatible with your favourite mp3 player. Some loss of fidelity may occur in the conversion.


(2) Monkey’s Audio (PC or Mac) http://www.monkeysaudio.com/download.html claims little loss of fidelity and the ability to convert back to the original file type. Both are free downloads.



Another option is to use a sound editor/recorder such as Audacity http://audacity.sourceforge.net/ which will allow simple editing and file conversion to a variety of formats.

Animoto - Slideshows 2.0

The future of computer programs is web applications. Look at Google Documents for example. You can create MS Office-like documents online on any computer in the world, all for free. Not to mention the ease of editing and sharing these documents.

I personally feel that this is a very exciting prospect for education. As a teacher I will no longer have to worry about purchasing software for basic computer activities, and I can count on my students being able to access the same tools so long as they have access to the internet.

One such tool that I absolutely love is Animoto. Animoto generates custom, professional-looking slideshows from user-uploaded music and photos. Their “patent-pending Cinematic Artificial Intelligence technology and high-end motion design” drives the web app. They say the Cinematic A.I. analyzes users’ photos and music like an actual director and editor.

After trying out their application I have to agree. The video slideshow it produces looks like I spent hours with fancy transitions and timing the picture movements with the music. Here is the sample I created with some ski photos from my xmas holidays:


Like most web app companies they have a free account and a premium account. The free account allows you to make 30 second videos, the premium allows for unlimited length and higher quality videos. Even better, they have an education version. If you apply as a teacher they will give you and your class unlimited accounts for free.

In encourage you to check it out.

A handy polling tool

A handy tool I’ve been using a lot lately is Doodle. It’s a funny name for a polling service but that is what it is; an online tool for quickly setting up and disseminating a poll. And it is so easy to use.


Doodle takes the pain out of organizing a meeting with a group of people. Instead of a series of emails going back and forth, I can set up a poll and have Doodle send an email to the email addresses I enter inviting those people to participate in the poll. They follow the link in the message, click to ‘vote’ for the days and /or times they are able to meet and that’s it. I can quickly see what the best time is for the group and can select the most appropriate option. All it takes is one more email to let everyone know the day and time of the meeting.

I’ve also used Doodle to facilitate a group choosing from among a number of options. For example, after a brainstorm of ideas, we used Doodle to have everyone vote for the ideas they thought were the best options. This gave us all time to think about it and to vote without being influenced by other people’s opinions.

We could do that because one of the options in Doodle is to hide the poll which means that users can’t see the other people’s votes. Other options include the use of an ‘ifneedbe’ setting, the ability to limit the number of OKs and the option to copy the url and send out the invitation yourself.

I haven’t explored the integration of Doodle with Outlook and Google or the widget you can add to your calendar or browser; I find it easy enough to access through my Delicious bookmarks. There are also paid versions, but I have found the free version has met my needs so far. If you try it and use these other features, I’d love to hear how they work.

Collaborating

We hear a lot in online learning about working in teams and collaborating on projects. These collaborations may require the development of one or more documents. But what happens when the ‘team’ can’t get together? Collaborating on documents by email is one option, but can get confusing very quickly with multiple versions of the same document being passed around. Who DOES have the latest version?

Recently I have been working with Wikispaces and Google Docs. Both require that you create an account. Both are free applications that are simple to use once you understand the concept. They allow you to work collaboratively in a single document or set of documents. They can be private, semi-private or public.

While Google Docs relies on well known document types, such as Word; Excel; PowerPoint, Wikispaces appears more like a set of editable web pages. Each has strengths and weaknesses and should be considered based on the need of the project. Of course the most famous, or perhaps infamous, collaborative project is of course Wikipedia. Whether you are a fan or not of Wikipedia, it has been an amazingly successful contribution to the World Wide Web as a resource and an exceptional demonstration of the use of a collaborative technology. For an article talking about its success see Simon Waldman’s article ‘Who Knows?’ at http://www.guardian.co.uk/technology/2004/oct/26/g2.onlinesupplement.

If you are interested in learning more about Wikispaces or Google Docs and how they might be used in your project or course, contact me (mrhodes@ualberta.ca) and I can help you get started.

Better Ways to Share Lists of Websites

Have you ever considered the method you use to share important websites with your students? My experience informs me that the majority of instructors create a document that lists the various websites and their website address (aka URLs). This document is either given to the students as a printed handout or available as a download online, usually from within eClass (WebCT).

I think it is important that people are aware that there are a multitude of ways to transmit this information to your students that, in my opinion, are much more effective and add extra benefits for students and instructors alike.

First let me set-up the downsides a paper list of websites:
  • A piece of paper is hard to file properly and have ready to access when I need it. When I am sitting at my computer planning a lesson 10 months later I have to remember where I filed that one piece of paper and look up a specific website. (not to mention how easy it is to lose a piece of paper).
  • A document list of websites does not facilitate sharing. What if a fellow student mentions during class of another useful website. Your students must now transcribe all the website information on the given document.
  • There is no easy way to share new websites or add new comments about the existing list of websites after the class has concluded. Sure students could email information to each, but now students are dealing with multiple locations of information that must be filed and organized.
  • It is difficult to communicate how to navigate on a particular webpage using a document list. In my experience the key information about many websites is something like “be sure to click on the _______tab and then select the _____ link in the navigation bar”. This is hard to capture in a document list. Not to mention the fact that as soon as a website changes it’s navigation structure (which they often do) this previous information is irrelevant and confusing.
  • A static document list cannot take into account when website addresses (URLs) change or particular resources move location within a website.

So guess what? There are ways to share websites with your students that counteract these pitfalls of a document list. If you are a U of A Education instructor, are interested in the various options and want advice on which will be the best fit for you I suggest you contact someone in Tech PD. We would be happy to consult with you.

However, I will also introduce you to my 2 favorite solutions:

Delicious.com is a social bookmarking application. It works exactly like your Bookmarks or Favorites menu in your Internet browser (eg. Internet Explorer, Safari). However the bookmarked websites are stored in an online account as opposed to on your computer. Therefor you can access your list of bookmarked websites on ANY computer in the world. You can also share a selected list of these websites with others. Even better, you can create a class delicious account that can pull websites from your saved bookmarks. Most importantly delicious uses a method of multiple categorization called tagging. This will allow you and your students to create a constantly updating list of websites that can be sorted and organized based on individual preferences. This is hands-down the MOST useful computer tool I use in my life!

Diigo.com is also a social bookmarking tool. It has similar features to Delicious in the sharing and tagging of websites. However Diigo also allows you to add virtual sticky notes on top of webpages. Imagine the possibilities! You can add little notes about all the tips and tricks you know about navigating these websites. If you want to allow it, students can add their own sticky notes thus creating an ongoing and updating resource. And imagine the possibilities for assessment. You could ask your students to create their won Diigo accounts and have them annotate some websites based an any number of criteria ranging from reliability to applicability to interest, etc… And once the students share these annotated websites with each other they now have an organized list of websites with helpful annotation. Wow!

And so by implementing a Web 2.0 solution to website sharing you add the following functionality to your list of resources:
  • A list that is always accessible online from any computer.
  • A list which is cross-categorized for the students and that also can be futher categorized based on personal preferences.
  • A list which can easily be shared amongst students as well as colleagues.
  • A List than can be added to by yourself or your students (if you enable this) at anytime in the future.
  • A list that can have comments and annotation added to it at anytime during the course or after, and these annotations can be made available to others if so desired.
  • Annotation about navigation can be easily added to website information. If this navigation ever changes, editing the annotation will automatically update itself for all people sharing the list.
  • If the address (URL) of a website or a web resources changes, all it takes is for one person in the sharing group to notice this and update the change. The list will now automatically update for all people sharing the list.

Welcome to the wonderful work of Web 2.0!

Attend the EDUCAUSE Annual Conference without leaving the Education building

Every year at this time, a large number of faculty and staff from across the university usually attend the annual EDUCAUSE conference. This conference provides information about current developments and networking opportunities for those who are interested in the use of information technologies in higher education. This year it is being held in Denver, Colorado from November 3-6. Given the financial crunch of the times, this year many find themselves not able to travel in order to attend. But that doesn’t mean we are going to miss it. In fact, even more people are going to be able to attend at no cost to them.

This year, EDUCAUSE is providing an online version of the conference from November 4-6. All 13 featured and general presentations and 18 of the concurrent sessions will be webcast at the same time as they are occurring in Denver. Vice Provost (IT), Jonathon Schaefer, has sponsored three registrations to the online conference, giving the campus community 3 separate feeds to the conference. By projecting each of these feeds, the entire U of A community has access to all but one concurrent session of EDUCAUSE Online conference.

The Online Program Support Group (OPSG) has organized access to the Online Conference with help from a number of faculties across campus, including the Faculty of Education. The Education building will be used as the locale for the conference. All sessions of the Online Conference will be broadcast in various rooms throughout Education North and South over the two and half days of the conference.

The detailed program of the online conference is available on the EDUCAUSE Online Conference website. The schedule of local time and location for each session will be posted around the Education building and can be downloaded here.

Updated schedules as of Oct 30:
Schedule for EDUCAUSE Online @ UA (Rooms/Times) - PDF, 5 pages

We are very lucky to have the conference hosted here in our own building. It will be easy to stop in for those sessions that fit into your schedule. Or better yet, plan to attend the entire conference! It won’t cost you a penny and refreshments are included. It’s the best conference deal you are going to get all year!
