In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.

Learners listen to an office conversation. They then review tips on how to improve the feedback they give others and practice writing a response based on the conversation they heard.

Learners examine the operation of the on-off control mode using a home heating example. A short quiz completes the activity.

Users examine ways for students to give feedback to their instructor about what they have learned and what part of the lesson is not clear.

In this animated object, learners examine a closed-loop feedback system that uses digital circuits to control the position of a gear rack.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

Students review the conditions for giving statements of praise in a way that will motivate employees. They then practice writing these kinds of statements.

In this learning activity you'll use critical thinking skills to rewrite appropriate responses to potentially sensitive words and phrases.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

In this learning activity you'll use critical thinking, personal opinions, and experiences to develop responses regarding communicating respectfully.

In this animated object, learners examine the operation of a feed-forward control system and its advantages over a closed-loop system. A brief quiz completes the activity.

In this screencast you'll identify and write assertive "I" statements that focus on BCF (behavior, consequences, and feelings).

Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.

Learners review the VDR and work six problems. Immediate feedback is given.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work practice problems in which the total resistance of the circuit is calculated. Feedback is provided.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Students solve five problems to determine the total impedance of a series-parallel circuit. Immediate feedback is given.

In this interactive object, learners review the CDR and work nine problems. Immediate feedback is given.

Students work practice problems to calculate the total resistance of a circuit. Feedback is provided.
