This chapter provides an overview of Easy Java Simulations (Ejs for short), the high-level modeling and authoring tool that we will use to make our models explicit and to run these models to study their behavior. To provide a perspective of the modeling process, we first load, inspect, and run an existing simple harmonic oscillator simulation. We then modify the simulation to show how Ejs engages the user in the modeling process and greatly reduces the amount of programming that is required.
