Students read an explanation of the operation of an operational amplifier that functions as a comparator.

Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.

This document gives an overview of lathe maintenance.

Students follow steps to transfer data from a list to a histogram.

The learner will recognize common gestures and identify the meanings associated with those gestures.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.

This learning object gives instructors an opportunity to review the definitions of formative and summative assessment and list examples of the evaluations they use. In a drag and drop exercise, they classify a variety of assessment tools as either formative or summative.

Learners access information on telephone techniques in the workplace and create customer focused responses.

Learners rank the most efficient ways in which workers retain information and create their own plan for improvement.

In this learning activity you'll explore how computers connected on a network use Ethernet technology.

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

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.

Students read how to determine and calculate the void ratio for a given sample of soil or aggregate based on the weight-volume relationship.

In this learning activity you'll review safety considerations for using a tubing/pipe bender.

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.

This project gives a drawing with steps to complete the activity.

Users of this learning object review a case study of an online student and her experience with her instructor. They determine the principles of good practice for teaching online.

Learners answer 20 questions related to providing responsible customer service. The questions are presented in a game show format, and immediate feedback is provided. A final score is given at the end of the activity.
