Students read how the Plan-Do-Check-Act Cycle is used in problem-solving and process improvement. In an interactive exercise, students organize process improvement steps following this model.

This screencast, we see how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.

In this animated activity, learners examine the symptoms of four cardiac conditions: coronary artery disease, myocardial infarction, congestive heart failure, and valvular disease.

Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.

Learners follow the seven steps involved in the lockout/tagout procedure. This activity has video content demonstrating the safety measures.

The learner will study an effective workplace email being written while a narrator explains the step-by-step process. The learner will distinguish the difference between poorly written and effectively written emails.

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

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

In this learning activity you'll examine how network address translation works.

The student will read MIC susceptibility results from a microtiter panel for various common pathogens. Results can then be interpreted as susceptible, moderately susceptible, or resistant by referring to interpretation chart.

Learners watch a short video showing the correct procedure for police officers to follow when making contact with a high-risk vehicle.

Learners follow an EMT response to a house where a man is complaining of having chest pains. In this detailed activity, learners examine response procedures, resources, and medications.

In this interactive learning object, students calculate a resultant of multiple forces acting in a concurrent, coplanar condition.

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 learning activity, learners will reflect on the meaning and impact of stereotypes in both personal relationships and work environments. Identifying behaviors, attitudes, and feelings associated with stereotypes are addressed in this activity.

In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.

Learners follow a timeline of the criminal law process, clicking on the steps to read descriptions of them. A quiz completes the activity.

Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.

Learners examine the operation of positive and non-positive displacement compressors used in pneumatic systems.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.

The learner will measure and record dimensions using a metric micrometer to an accuracy of plus or minus .01 of a millimeter.

In this activity, you'll identify ways to prevent and address sexual harassment.

In this activity you'll explore how flowchart programs can be converted into pseudocode programming.

Explore the step-by-step procedures to rescue and care for electrical shock victims.
