In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.

Learners read a description of inductors and view examples of inductors in series and in parallel.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

Students read how profits can be doubled with the elimination of only a fraction of the "waste" in a company's operation.

Learners read a passage and answer two questions based on the information found it that passage. Immediate feedback is provided.

In this interactive object, learners follow the steps required for the Ziegler-Nichols Continuous Cycling method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

In this animated object, students examine the role that the solubility of water plays in various biological functions.

Learners solve two sample problems for an abstract reasoning assessment.

Learners solve two sample problems for a mechanical reasoning assessment.

Learners solve two sample problems for a numerical reasoning assessment.

Learners mentally manipulate two-dimensional diagrams to visualize the objects in their three-dimensional forms.

Learners choose the meaning of a selected word in a sentence.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In this learning activity, learners review the value of health and wellness as it relates to exercise, nutrition, intimacy, and spirituality. Examples of each are identified, and learners are given the opportunity to reflect on how these examples are associated with health concerns in older adults.

In this animated object, learners follow the steps for solving word problems using algebra. An introductory example is explained.

Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.

The ohmic region of the E-MOSFET is identified. Formulas are given to determine the proper operation in the ohmic region. An example of circuit analysis is also given.

Users view effective and ineffective methods of assessing a task. Flight training is used as an example of an area that needs authentic assessment.

In this interactive object, learners vary the value of the resistance to see how it affects current. Example problems are included.
