I enjoyed exploring bubbl.us, Education Oasis and Exploratree. bubbl.us had the ability to create organizers using a parent and child bubble hierarchy. I didn't see this approach in the other two tools. Relationships between bubbles are made by using directional lines in bubbl.us; lines and arrow graphics can also be made in Exploratree. In Exploratree the font style, color and size can be changed. While the color of the bubbles can be changed in bubbl.us, I didn't see the ability to change the style or color of the text.
Exploratree offered a wide variety of ready made organizers that could be completed on-line. I didn't see this option on bubbl.us. Both Exploratree and bubbl.us provided the opportunity to create custom organizers. Exploratree can accommodate the inclusion of JPEG files into the documents. I didn't see this as available on bubbl.us. I felt like this would really add to the interest of organizers and brings in the non-linguistic representations that help students make connections. I also liked Exploratree capability to lock elements so that they can't be changed by other users.
Both Exploratree and bubbl.us had the ability to share, print and e-mail the documents. In bubbl.us the code can be obtained so that the organizer can be included in blogs and other websites.
Education Oasis offered 58 free PDF organizers including the following types:
- cause and effect
- character and story
- compare and contrast
- sequence, cycle, timeline and chain of effects
- vocabulary development and concept organizers.
Some of the organizers can be completed on-line and then printed. Others can't. This site seems to primarily be a library of pre-made, unchangeable organizers. I think I would use it for basic organizers that I want students to complete by hand. I would use the other tools if I wanted to do a custom organizer or if creating an organizer was part of the learning task.
With all of these options it made me wonder why anyone would buy a graphic organizer book at the teacher supply store.
