As we must know by now, not all learners are the same. All cannot process new information equally. As instructors it is important to create pathways and connections between content inside of a larger picture. Using graphics to enhance text or to complement a lecture is fundamental in keeping learners engaged and cognitive of these connections.
Graphic organizers tend to make information less "fuzzy" and more precise for learners having trouble grasping the desired concepts. They allow students to separte what is imporant from information that may be interesteing, but not as critical to the overall cognition of the topic at hand. Personally, whenever I am assigned a text reading about something I do not always use graphic organizers. I wish more teachers would have used them in their instruction with me because I think it would have made clear the areas I really needed to focus on, instead of the areas I just found interesting and easy to comprehend.
They should be created by teachers and students, not just looked at and discussed. Students need to learn how to build these structures for themselves, after thoroughly be instructed on how to do so. It is recommended that the teacher first show the students how to set one up, then the class does one together. After this, students should work in small groups followed by working individually on constructing their own.
The ultimate goal of using concept maps and graphic organizers is to encourage students to become strategic learners. They need to be able to apply analytical, critical, and creative thinking skills in all walks of life - not just the classroom.
