Simulation of the month

A simulation of the junction field effect transistor Do you know how transistors work? These simulations, designed for technology and engineering students, will walk you through the physical principles of field effect transistors, and explain how they are used to construct logic gates.

Creating your simulations

Besides using existing simulations, MW is also a modeling tool for teachers and students to create their own simulations. Currently, MW supports three types of simulations: classical mechanics simulation, molecular dynamics simulation, and quantum dynamics simulation. MW allows you to easily share your simulations with collaborators. Learn more in MW's Online Manual…

Creating your activities

MW also has an authoring system for teachers and curriculum developers to create or customize their own online lessons that use models and simulations. A typical MW activity consists of a series of scaffolded pages that contain text, simulations, graphs, navigation links, and embedded assessments. The user interfaces of simulations in MW can be customized for students of different levels (grades 6-16). When learning with an MW activity, students can save their work in an Internet portfolio, create reports, and submit reports for grading. Learn more in MW's Online Manual…
