Hi Christy - Welcome to the community.
I wasn't familiar with Flixtime, but now that you've shared it, I'm very excited to pass it along to my building teachers. I love the fact that users have a full minute rather than 30 seconds giving us just a bit longer to work with. I'm thinking of having the students use Flixtime to practice oral storytelling in 60 seconds. They would have the slideshow play on the projector while telling their story in front of the class. It would be a great backdrop for visuals. Thanks for sharing!
Glen, it has been about a year since I last used Screencast -o-Matic, but I found it a little wonky. That may have been me. There are some good features on it, but for the general classroom, I'm not sure I would use it. One of the features I like it the ability to create a lesson and then post to the website for students to use.
Another site you might want to look at is utipu.com/app It is similar, but I thought it was easier to use. Again, it's been almost a year since I last used it and it too had some "wonky" issues.
Another free graphic organizer tool I love is http://bubbl.us. It is easy to use and free! I've created a list of other sites that are great for teachers in a wiki - http://techtoolsandtips.wikispaces.com/Content. I've listed a lot of interactive games and simulations by different subject areas. There's also links on the side for other sites that support collaboration and information literacy skills. I need to update this site before school starts and add much more to it. These are just examples of different types of resources that I share with teachers in workshops.
Glen, here is yet another site similar to Visuwords and Visualthesaurus. It is http://www.lexipedia.com/ This one seems to be a little more user friendly than Visualthesaurus.
Flixtime is nice - I, however, prefer to use the Animoto Education account option. Each teacher who signs up through this method gets "unlimited length videos". In addition, each teacher receives a code for students to use. During the next six months, each student may use this code to create unlimited length videos. My students have done some awesome work on their own using this "education code" option.
I was unfamiliar with utipu.com/app. I just tried to bring it up and check it out - I get an error message that the service is unavailable. Perhaps it will be an option for me to check out later. Thanks for giving me the tip about how challenging you found Screencast-O-matic was to use.
Although Jill mentioned ReadWriteThink, I want to add the Verizon Thinkfinity site as a whole to the list. Through this one-stop-shop teachers have access to free content-focused resources and teaching materials. However, the best part about the site is that the materials are provided through trusted content partners aligned to national standards. You can't go wrong with that!
Stephanie, another great site in the vein of Thinkfinity is http://www.sascurriculumpathways.com/. In the left side middle of the page is the link to register for a subscription. The subscription is FREE. This is a fantastic site. The writing revisor is worth the time. Take a look.
I may not have read EVERY message in this thread yet, so I am not 100% sure this site hasn't been mentioned yet. How Do I at http://ouseful.open.ac.uk/howdoi is a very helpful site to find instructioinal videos online using a search engine style interface. Give this a whirl and let me know what you think.
Also, how could someone share this with other teachers in a way so as not to offend those whose only online video use is with the Blue Screen of Death?
