This study compared the use of paper/pencil and computer tools for creating concept maps. Participants were 52 students in two combined 9th/10th grade biology classes. An independent measures research design was used. There were two treatment groups: computer and paper/pencil. The computer group created concept maps using Inspiration software on desktop computers. The paper/pencil group made concept maps in the traditional manner. The t statistic was used to evaluate the mean difference between the two treatments. The group using the computer created more complex maps than the group that used paper/pencil. This difference was significant.
