Venn Diagrams

 

Venn diagrams can greatly enhance students’ ability to understand and use material presented in text form. Typically, Venn diagrams have two or more overlapping circles that are used to compare and contrast material. The overlapping section is used to show the characteristics that are similar between the two materials. Venn diagrams serve to aid comprehension and learning by interfacing vocabulary that explains, clarifies, and illustrates the informational structure of the concepts. As students create and design the graphic representation of the text, they are required to reread, discuss, and explore relationships within text. Venn diagrams are also an effective ways to brainstorm, plan, and organize writing.

 

Step by Step:

 

1.   Identifying Contrasts and Comparisons

The teacher identifies within the text possible points of comparison and/or contrasts.

 

2.   Discussing Points of Comparison and/or Contrasts

The teacher engages the students in a discussion about the similarities in the designated elements or topics to be compared and contrasted within the text read. As students identify similarities, the teacher lists them vertically on a chart, overhead, or chalkboard.

 

3.   Constructing the Venn Diagram

Once similarities are listed vertically, the teacher draws overlapping circles with the list of similarities contained within the overlapping section of the two shapes. After the circles or shapes are drawn, they are labeled to indicate the concepts, stories, or aspects of the stories being compared. Then the teacher places the differing elements inside the appropriate shapes to provide the comparative analysis.

 

4.   Reviewing through Comparative Discussion

The teacher will now engage the students in a discussion related to how they made choices and decisions regarding their selection of elements and the placement of those elements within the Venn Diagram. The teacher encourages students to elaborate on and justify the positions they take relating to their choices for placement of elements or suggestions for changes within the diagram.
