In this learning activity you'll test your knowledge of the different types of steel rules as well as how to use and read them correctly.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.

This interaction tests the student's knowledge of parts on a radial drill press.

In manufacturing, controlling the production process is critical. Part of this control is knowing when to make adjustments and when to let the line run. Step onto the production line in our manufacturing plant and learn what process variation is and how it impacts your bottom line.

In this learning activity you'll examine a stateful packet inspection firewall that keeps track of legitimate Internet service requests, also known as dynamic packet filtering.

Learners review the process for calculating board feet and use virtual samples to practice the process.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

Meaningful measures administered by learner-centered teachers represent a multiple and varied body of evidence. Match the terms to the definitions to learn about the categories that make up meaningful measures of assessment.

Test your knowledge of measurement by answers the questions!

You'll practice converting between units of measure for length in the metric and English measurement systems.

Learners get a hit each time they answer a question correctly. A student may test his/her drug calculation skills by playing the baseball game alone, or against another player.
