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.

Resources for Teaching Poetry

Just came across Google's tool, Search Stories, for creating a video out of your online searches. I did one on Resources for Teaching Poetry.

It's a pretty nifty tool, and students might get a kick out of using it as a way to present their initial searches in a content-based project.

WallWisher

WallWisher is not as useful pedagogically as other social networking tools I can think of.

You can add a picture (from a URL), or video, or audio file, but it doesn't have a way to put a URL into the text (without using up the tiny letter count), so that users can easily go visit the site. If you want to illustrate your sticky, you need another place/server/or knowledge of how to get an image location to stick it in. You can post to Facebook, et al., and link to pictures in Flickr.

The limited number of words/letters on a sticky means you can't say much--this is probably an advantage for young learners, but not necessarily for their education. A blog or wiki would give them the opportunity to be more expansive.


You could have a main sticky and then ask students to respond to it. But there is no way to organize the stickies besides moving them around physically. So this means the teacher/owner of the wall must do the work of organization, or let things happen at random. (See Nik Peachey's wall of teacher tools for social networking.)

So on the whole, I like the idea of a communal blog or wiki better: more opportunity to write expansively, ways to comment, RSS feed, easy ways to include URLs and lots of pictures, and esp. with a wiki, ways to organize pages.

But I can see Wallwisher as a way to make comments on an event or single Web page. You might have students visit a page or view a video (or put one into a head sticky), and then make a short comment on a Wallwisher page. If you have only 15-30 students, they could all read each other's comments (but if they then make more comments, you've quickly got a huge, disorganized mess...) If you use WallWisher the way it was intended, perhaps to wish a class member happy birthday, or to congratulate someone on getting citizenship, or to make a wish list, or to put up reminders for a project, then it's a nifty application.

VUE - Visual Understanding Environment

I have explored VUE, a project of Tufts University, while looking at a variety of mind-mapping or concept-mapping sites and software. VUE is free and has an excellent, visually attractive video explaining its features. It seems to combine the best of mind maps, presentation software, and the flexibility to link across several different concept tracks. It is well worth exploring for advanced student projects, for example, involving research and media, and is a free download and cross-platform (but not for Mac X.3). It looks to be an excellent presentation platform because, unlike PowerPoint, it can combine linear and non-linear approaches to presenting.

Dipity

Dipity has an easy Google-type interface that allows you to create a timeline. This is an example from Michael Coughlan's Life.

Other Webheads have suggested using the interface in a jig-saw activity, where groups of students can add the info they collect as they read or research. You can add info/pix from other sites, such as Twitter and Flickr.

WritingFix

Definitely for advanced learners, WritingFix is targeted toward U.S. high school students and teachers. However, it has a lot of good advice about writing, and is billed as "the home of interactive writing prompts." Various parts of the site will generate random prompts to start writing on a variety of topics and content subjects. It also has general advice about writing essays, e.g., developing voice, organizing, sentence fluency, conventions, etc. In Spring of 2008, the site will have an extensive section of the various parts of the writing process. A good place for EFL/ESL teachers to grab ideas.

CoPe_it! and other Mind Map Managers

CoPe_it! was recommended by some Webheads looking for Webware to edit mind maps collaborately. This tool appears to have nice visual effects and is directed to

supporting argumentative collaboration and decision making for Communities of Practice.

Other tools mentioned were Gliffy (discussed elsewhere in this blog and something I've used quite a bit for very professional-looking diagrams), Thinkature (real-time collaboration on the Web, allowing the use of your own photos and drawings), and the software, MindManager (for both Mac and Win/DOS), which is not simultaneously collaborative, as I understand it.

Other visual-assist tools include FreeMind, a free, downloadable, Java-based software purportedly faster than MindManager because of one-click "fold/unfold" and "follow link" operations. There is a gallery with some jazzy examples, and you can upload/archive your own there for free, too.

Skrble is an online whiteboard with collaborative features that you can put in your blog as a widget:

Start skrbl & give out your URL; instantly share online. Collaborate with others or, keep skrbl your own private web space.

Bubbl.us looks very cool as a collaborative tool and suggests it might be useful for brainstorming. Love the concept, but like much of Java-based stuff, it tends to be a bit slithery. It will take a little getting used to to use the "bubbles" with facility.

Mindomo is another mind-mapping tool:

Mindomo is a versatile Web-based mind mapping tool, delivering the capabilities of desktop mind mapping software in a Web browser - with no complex software to install or maintain.

Create, edit mind maps, and share them with your colleagues or your friends.

So all of these share some features and would involve a bit of trial-and-error to decide which worked best for your students.

Thanks to Moira Hunter, Carla Arena, and other Webheads for good links!
