Mostly Free Diagramming Tools Online

I've been exploring several drawing tools, particularly those for making graphs and diagrams. I'm trying to stick to free and online in this discussion, though a few for-pay tools have some nice advantages, mainly storage space and collaboration.

Among other advantages, drawing tools can help students mind-map and brainstorm; collect and display numerical data in charts and graphs; demonstrate reflective learning in storyboards or networked images; and so on. Graphing skills become increasingly important as an academic tool as students progress through school, but charts and graphs can be a fun motivation even for younger students.

Gliffy is one of my old favorites, but it limits you to just 5 drawings, unless you go for the somewhat pricey paid account (5 users for up to 200 drawings, for about $10, as of this writing). It does very nice Venn diagrams from templates, has loads of pre-formed objects, such as arrows and rectangles, and supports HTML5.

Cacoo is entirely free and looks like a very friendly interface, and one appropriate for middle school kids. You can create:

wire frames, mind maps, network charts, and site maps . . . simply pick and "drag and drop" elements from a large library of stencils.

Cacoo is one of the free programs with a free-hand drawing option, too.


Creately is another free program with great features, and like Gliffy, allows up to 5 drawings with limited collaborative possibilities.  It gives you only diagrams, but offers nice Venn templates, and a large selection of templates for K-12, including:

...Storyboards, Fishbone Diagrams, T Charts, Y Charts, Venn Diagrams, and much more..

Google Drawings has only a very basic toolkit, so don't expect a great deal, but it is quick and easy and the interface will be familiar from Google docs.


If you want a very professional look, but have only a limited project, try Microsoft's Visio or SmartDraw. Both of these have a free trial period and many features.

Free File Converter for Mac and Other Things You Might Want to Know about YouTube

Recently I tried to organize and curate my YouTube channel to better effect. My first problem was that as an inveterate Mac user, most of the videos on my desktop were in .MOV format, and even though this was purportedly a YouTube-supported format, I could not seem to upload some of my videos.

Some of the most popular video formats supported by YouTube (directly from their Help site:

• WebM files--Vp8 video codec and Vorbis Audio codecs
• .MPEG4, 3GPP and MOV files--Typically supporting h264, mpeg4 video codecs, and AAC audio codec
• .AVI--Many cameras output this format--typically the video codec is MJPEG and audio is PCM
• .MPEGPS--Typically supporting MPEG2 video codec and MP2 audio
• .WMV
• .FLV--Adobe-FLV1 video codec, MP3 audio

The only error message on the YouTube upload page was something to the effect that "There is a problem with your file."  After much trial and error, here are some things I learned about video file formats and YouTube.

 Believing the .MOV file format might be the problem, I tried about half a dozen free video converter software apps on my long video. None of them would convert a video of any length for free, despite plastering the word "free" all over their download sites. 100 MB is about the limit without paying extra, including online converters. I finally came across QTAmateur.app at the Mac Update site. Despite the dopey name, this little software is very powerful and converts to many different video formats quite easily, including those usable by PCs and mobile devices. And it is an absolutely free download. Use ("Export" to make the conversion.)

This was a fortunate find, as I want my videos to eventually be playable on mobile devices as well as on desktops.

I still had a problem, in that YouTube kept saying something was wrong with one particular file, even though it was quite small when converted to mpeg4. It turns out that YouTube goes by time, not file size, and allows only 15-minutes maximum play time. However, when you verify your account using a mobile phone number, Google will send you a text code that gives you up to 2-hour lengths. YouTube is very non-informative about this fact, and it probably relates to an improvement resulting from Google taking over YT. Maybe the help pages and links will be improved in the coming months.

I found the information about how to get the extra size files (the link didn't just jump out at me) by searching videos in YouTube (of course). I found several, the best and simplest of which, I think, is How to Increase Your Upload Limit on YouTube.

With an officially "verified" account and armed with the increased upload limit, I got my video up. See The Effects of Technology on SLA, a talk I gave at TESOL New York, 2008, in either .avi format (a little clearer, below) or .mpeg4 at my YouTube channel. Just FYI, this was originally a Powerpoint slideshow saved as a Powerpoint movie.  I may yet get around to putting the .mov version up, but you can play it with most video players on most platforms anyway.

Using QR in the Classroom

You may have noticed increasing uses of QR (Quick Response) codes, for example, to make a trail of ecology facts in a national park, or to provide a self-guided tour of a museum exhibition. I've returned to this YouTube video, from the American TESOL Institute channel, several times, as it has some great ideas for using QR (Quick Response) codes with students:



http://youtu.be/V0kdbBTwF7U


The video describes what QR is, how you can make your own, and how you can teach students to make their own for content-based projects, to link to podcasts, to make electronic portfolios, etc. For example, as seen in this image, students can scan the QR with their mobiles to get more information about skeletal structure.





If students construct the content they create reusable learning objects for subsequent classes to read, listen to, and improve.

Thanks to Webheads for finding this great video originally. There are a number of other videos on QR with more ideas in the YouTube sidebar.

EduMOOC

Google's EduMOOC is astounding and fun. You can be in touch with 2500 teachers and learners in the grand experiment in volunteer, free, online learning.

Although the MOOC is just for this summer (July-August), you can use the discussions, videos, and resources (Diigo group) asynchronously. Read all about it at Polly Peterson's Education-Portal blog.

TED: John Underkoffler points to the future of User Interface

This video from the TED (Technology, Education, and Design)conference in February (Long Beach, CA) has some astonishing new ways to look at user wetware-computer connections.




It's amazing to see Tom Cruise's Minority Report interface now displayed with many different ramifications. The new interfaces use computations that are "space-soluable and network-soluable," allowing a user to drag/send their visual information from one "monitor" to another,both co-located and in space, with a hand gesture. In five years' time will this be the computer we get??

Web 3.0

Webhead Moira Hunter tipped me off (see her blog) to this interesting video about Web 3.0, the semantic Web, as seen on Kate Ray's Vimeo site:

Web 3.0 from Kate Ray on Vimeo.

It gets increasingly interesting as you watch: should the semantic Web have pre-defined ontologies? Of course, Vance Stevens and most Webheads would answer a resounding "no!" If contemporary Web is increasingly about social networking, it is left to developers to help us find and explore new ways of interconnecting.

TinyChat

TinyChat looks to be a very useful little Twitter-related tool for meeting up with students or colleagues on the fly, especially if you have a Webcam built into your computer. It's free and anyone can enter by typing in a nickname--or you can make the chat private.

The Bases for a Personal Learning Network

These are excerpts from a Kim Cofino fireside talk at WorldBridges, as edited by Vance Stevens.

Her main points form the basis for a Personal Learning Network--what every teacher really needs in the Digital Age:

Tools
- RSS feed - find out what other professionals are thinking about and stay up to date
- Join an education social network - learn and share with other teachers
- Start a blog - express yourself and monitor your own growth as a professional
- Use Skype to share and connect with other professionals
- Attend online conferences - both synchronously and asynchronously [WorldBridges is a good place to catch up and get into conferences]
- Use Twitter - find professionals and make connections [Vance's own anecdotes are clear illustrations of how useful this can be]
- Design global online interactions for your students [e.g., iEarn, GLOBE, or your own class-to-class project]

Attitudes
- Be more flexible and try out more collaborative approaches
- Allow for student-led processes, and learning from peers
- Learn, create, and share with your students
- Use the Internet to let your students connect with other students--and teachers--around the world
- Students in developing countries already have "global attitudes" - multicultural and multilingual perspectives, so take advantage of these

Pranav Mistry's Sixth Sense Technology

These wearable technologies were seen about 10 yrs ago at the MIT Media Lab, but this goes even farther (and smaller). Clever, and Mistry wants them to be open source. (About 13 min., but a must-see.)

ScreenJelly

This little screencasting app, ScreenJelly, seems very easy to use, though it has only a 3-minute recording time limit. You can record what you are doing on your computer screen with your own voice-over. The program is very self-evident, i.e., it takes only a few minutes to figure out how to use it (and there is a helpful how-to video both here and at Stannard's TTV site). I can see its immense usefulness for a teacher (or students) to create little help videos for new technology learners. Links or embedding are possible with such social Web tools as Twitter or Flickr, et al.

Thanks to Russell Stannard--found on his most useful site.

Sidebar RSS Aggregator for Firefox

The explanation below is pretty minimal, but the Firefox site will give you illustrated directions to get started. While it claims not to be a replacement for a full-fledged aggregator, it functions quite nicely as a quick and easy to install reader. This might be an easy way to get students reading each other's blogs.

Google's Evernote

So here is a totally cool tool: Evernote by Google. You can use it with your mobile or with any browser to capture stuff in a permanent file visually. But Evernote will even read words in an image--including handwritten words. So, for instance, you could take a picture of a sticky note on your mobile and send it to Evernote to retrieve, by search, later on.

This will no doubt give new impetus to ways to read images that are intending to avoid spamcatchers, but I love the concept.

Thanks to Rita Zeinstejer of the Webheads for this tip!

Google Wave

This is an amazing new app from Google that allows instant texting, email combined with live/real time bulletin board, and shared pictures á la Flickr. But that's not all--you can blog and embed the pictures and continue the conversation live via the blog or social network, e.g., on Orkut. Anyone can join in at any point in the conversation, and get a playback of what went on before--or create a private "thread" on the side with specific users. Best of all (for some) it is open source, so you can make your own applets for it.

Using Mobile Technologies for Education

There was some discussion of using mobile technologies (cell phones, iPods, Blackberries, etc.) at TESOL Denver this year, but the following is the most succinct list I have seen:

Forwarding an edited mail from the Wikieducator list (Randy Fischer)

Randy found this 2008 University of Nottingham study on Mobile Phones
and secondary education, and thought it might be of interest.
http://emergingtech nologies. becta.org. uk/upload- dir/downloads/ page_documents/ research/ lsri_report. pdf

Several interesting things caught his eye:

1. the fact that in many schools, students 'own' their mobile phones,
not necessarily the computers. (Physical ownership and use feels
good);

2. the list of 15 Useful Things Students Do with Mobile Phones (below)

Could we use some of the 15 or more useful things to design
appropriate and culturallly- relevant learning activities?

What role could WikiEducator play in learning that uses mobile phones?

Fifteen useful things students did with mobile phones
1 Timing experiments with stopwatch
2 Photographing apparatus and results of experiments for reports
3 Photographing development of design models for eportfolios
4 Photographing texts/whiteboards for future review
5 Bluetoothing project material between group members
6 Receiving SMS & email reminders from teachers
7 Synchronising calendar/timetable and setting reminders
8 Connecting remotely to school learning platform
9 Recording a teacher reading a poem for revision
10 Accessing revision sites on the Internet
11 Creating short narrative movies
12 Downloading and listening to foreign language podcasts
13 Logging into the school email system
14 Using GPS to identify locations
15 Transferring files between school and home
