Graphic organizers have long been used in the classroom to facilitate learning and literacy. Concept mapping is a type of graphic organizer that is commonly seen in science classes. Concept maps can be made with traditional pencil and paper, word processing software, or online tools. Bubble.us is an online concept mapping tool that is very useful. It can be used on a computer, iPad, or iPhone, but is unavailable on android devices. This tool is free for the first three uses and then costs $59 per year. There are a variety of ways the concept maps can be set up (here are a few examples). Teachers have mixed reviews of Bubble.us, with some saying that it is easy to use and others complaining about the cost of the tool. The tools in Bubble.us are easy to use and there are a variety of colors to choose from in order to tier the concepts visually. Users can also insert pictures into their concept map. One of the issues with Bubble.us is the concept map is difficult to modify after it has already been created. Although it is easy to change the text or add a new connection, deleting a connection changes the color hierarchy. Also, the display of a single concept with multiple sub-concepts could be improved. Here is a video review of Bubble.us and a demonstration of how it works.
