An interactive App for understanding and applying the Supply and Demand Model.

The purpose of this app is to help students understand the effects of changes in variables of supply and demand, in a microeconomic market under perfect competition.

With this app students can interact with both curves and see the equilibrium point in terms of price and quantity demanded. This tool allows students to complete exercises relating to the subject and put into practice their knowledge.

The program assumes that students are familiar with the underlying concepts of the graphic representation of a market with perfect competition.

For a better understanding of the main effects of the changes in the curves, this graphic resource allows students to make only one move per curve and does not envisage changes in the curves´ elasticity. Students can interact with both curves (demand and supply) either separately or jointly.

There are also simple exercises that enable students to test their comprehension of how the market works and check their answers through interaction with the graphic.

As the Author of the documentation mentions:

"This multimedia material has been designed to be used together in introductory economic courses. Without doubt the key to success of these materials is the fact that both professors and students alike find them incredibly simple."

Some students who used it said:

- It helps to understand the theory. Explanations when choosing the correct answer are very useful.

- Fantastic product, clear and concise presentation - mechanics really helped the learning process.
