Children nowadays are appealed by everything that has to do with technology. If possible, they would rather learn on a computer than attend a traditional class. This is why many schools and colleges have now adapted to the modern times that we are living and are providing computers and computer-based lessons for the students attending them. However, there are many schools that do not have such a high budget and cannot afford to invest in technology. Keeping children entertained and attentive is pretty hard, especially with so many distractions around, such as smartphones and other electronic devices. Teachers can now make classes more interactive in a very simple and effective way: by using Venn diagrams. These diagrams were invented by John Venn and based on Euler’s idea.
They represent a great way of picturing relationships between different groups of things. Basically, they design and compare attributes and characteristics of items, which can be either people, places, objects, events, ideas, animals etc. A simple definition of the Venn diagram would be two items linked by characteristics or attributes. These diagrams are useful when it comes to graphics organization and when comparing two things. They are represented by two or three circles which are contained in a universe. Let’s call the universe “animals”. If, for instance, you want to classify animals, you can draw two circles representing small and furry animals. The diagrams should then be populated with, naturally, small and furry animals. You will then see that small animals can also be furry, and the other way around, meaning that they share certain similarities. This is why the circles should be overlapped, with small but not furry animals on the right, furry but not small animals on the left, and small and furry animals in the middle, in the overlapping portion of the circles.
The Venn diagrams can make classes more interactive because children can simply draw empty circles on the blackboard, choose the “universe” and the items to be compared, and then let children “populate” them. In turns, each student will be able to write something, which will make the class so much more interesting. Since they will be directly involved, they will pay more attention and will be able to learn faster and easier. Venn diagrams will organize students’ thoughts and will keep their mind off gadgets and technology. Since a Venn diagram can successfully be applied to a wide range of subjects, every teacher can benefit from their use.
