Visual metaphors are becoming a popular teaching tool in the classroom. What exactly is a visual metaphor? A visual metaphor is substituting an idea or object with another and is used to help explain a concept or an idea. It is done using visual imagery or symbols. We see visual metaphors everyday, especially in advertisements. Since educators have access to different types of media (like web 2.0 tools), why not introduce visual metaphors as teaching tool? Our ability to learn via images dates back to the time where information was passed down by oral history. Some experts claim its wired into our brains to learn through visual metaphor. So you’re interested in using this teaching tool in your classroom, but your budget is tight. Well why not use some free open source programs that could help you create visual metaphors that would complement the literary metaphors you use in the classroom. Here is a list of open source programs that can get you on that track.
The GIMP- The GIMP stands for GNU Image Manipulation Program. If you are familiar with Photoshop, than the GIMP is the open source alternative to it. You can load photographs and edit them in the GIMP. Change colors, edit and crop, write text, the possibilities are endless!
Inkscape- Inkscape is a vector art program. You can create images, graphs, charts, etc. and you are able to resize them without losing the quality (sharpness) of the drawn objects (since they are vector). Create simple or complex diagrams to help explain a process or problem.
Blender- Ever want to demonstrate something in 3D? Well you can create and animate simple or complex models in Blender. It’s recommended that you have some experience in 3D software, but it is not required. The user interface can be tricky at first, but it becomes easier with experience.
The GIMP, Inkscape, and Blender have many user forums and a big user community, so there are a lot of free tutorials and documents to help get you started in your open source journey. Use these tools to help create your visual metaphors that will help your students connect with concepts in the classroom. Happy exploring!
