This module includes three different lessons that use modeling to help students have a visual understanding of computer programming topics.

The lessons include:

• Introduction to Programming and Control Structures using NetLogo 

This lesson uses NetLogo as a tool to introduce programming as well as the use of control structures.  It may be used very early (even first day) in a Introductory Computer Science class.

• Solving the "Fast Food Restaurant" Queue Problem with STELLA

This lesson is for students late in a first year programming course or early in a second year course.

• Visualizing Binary Trees with Mathematica

This lesson is for students in a second year programming course after they have learned how to manipulate pointers.
