Learners view the operation of an NPN transistor in the active region.

The learner will identify active and passive voice and distinguish between the two.

Students read about the world's active volcanoes that make up the "Ring of Fire." In an interactive exercise, they locate these volcanoes on maps.

Learners will examine the four steps to listen actively to improve relationships.

In this learning activity you'll evaluate the immune response including active, passive, natural, and artificial immunity.

In this interactive learning object, learners follow a strategy for identifying specific and general topics to improve their ability to find the main idea of a passage.

In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

Instructors complete a simple, informal inventory that helps them to see how they use the Seven Principles of Good Practice in Undergraduate Education developed by Chickering and Gamson (supported by AAHE, ACE, Johnson and Lilly foundations) in 1987.

Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.

Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.

In this simulation, learners follow 10 steps to program a job to saw metal. This activity includes a video clip.

In this learning activity you'll use active listening skills to answer 10 questions based on a story.

In this interactive object, learners follow steps to program and operate the Ercolina Top Bender.

The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.

This activity is cognitive. Learners will actively listen to a story activated by the computer. Then learners will take a quiz on their comprehension. Lastly, learners will compare their chosen answers against the answer key to determine how well they really did "actively" listen. (Credit given to Tom E. Wirkus, University Of Wisconsin-LaCrosse for this activity.)

In this simulation, learners follow a series of steps to operate the Marvel Saw PCII in the manual mode. This activity includes a video clip.

In this learning activity you'll interact with the Johari Window to illustrate how willing you are to disclose information.

Learners are asked to control the Adira press brake following the same steps they would if working on the actual machine.
