In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.

In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.

Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.

Learners will write effective business messages that incorporate a second-person point of view and focus on the benefit to the reader. This approach is often used to create positive messages, neutral messages, and inquiry messages in business settings.

The learner will understand how to view an object for interpretation in the standard orthographic format and then accurately sketch three orthographic views using 3rd angle projection.

Students view a world map and click on a country or continent to read about how the people there view time. A brief quiz concludes the activity.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.

Students read about the concept of true power and view examples of how it is dissipated as heat is provided.

Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.

Students view the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous voltage of a charging RC circuit.

Learners view a sample of the keystrokes from a TI-35X or 36X calculator that are required to solve for the instantaneous voltage of a charging RC circuit.

Students view the formulas to be used to convert a series impedance to a parallel impedance.

Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

In this interactive object, learners view a practical application of a PLC Timer-On function.

Learners view practical examples of how a Hall-effect sensor is used.

In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.

Students view a demonstration of Kirchhoff's Current Law (KCL) using complex numbers with respect to ac.

In this learning activity you'll view a graphical layout of the transactional communication model.

Students read a definition of Kirchhoff's Voltage Law and view examples of its use.
