In this learning activity you'll examine how a sine bar is used to measure angles.

In this learning activity you'll calculate sine bar problems.

The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave displayed on an oscilloscope screen.

Learners examine the seven most common barriers to effective listening and consider suggestions for how to overcome these barriers. This interactive object contains audio.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

Learners examine the psychological and sociological barriers that interfere with clear communication. They select examples of ad hominem fallacy, bandwagon fallacy, emotional appeals, red herrings, irrelevant appeals to authority, suggestibility and conformity, “poisoning the well’, and “shoehorning.” In an interactive exercise, learners identify ways to overcome these barriers.
