In this interactive object, the learner examines the basic terms used in division. A quiz completes the activity.

Learners answer questions about foundry-related technology and terms using a game board format. This learning object can be used individually, in small groups, or as a class activity to provide an alternative self-assessment tool.

In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this interactive object, learners examine the properties of equality and use those properties to solve simple equations.

In this interactive object, students work 11 practice problems and solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Students interpret pie chart information and identify the parts of a chart in an interactive exercise.

Learners follow an EMT response to a shopping mall where a teenage girl is choking on food. In this interactive object, learners examine response procedures, resources, and medications, and determine what actions the EMTs should take.

Learners test their ability to visualize a mounting wedge in this interactive exercise that features animated pictorial views.

In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.

In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this interactive object, learners read how to use the indefinite articles "a" and "an" with singular count nouns. They omit these articles with noncount and plural nouns. The students then practice using "a" and "an" correctly.

In this interactive lesson, learners read the rules for filing business records and then test their knowledge in a series of exercises. Immediate feedback is provided.

Users of this learning object evaluate the early online experiences of four hypothetical students and record the lessons that can be learned about what to do and what not to do to create effective online learning environments.

2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a mounting wedge. A short quiz to test your ability to correctly read this information follows.
