In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.

Learners study the operation and characteristics of an incremental optical encoder used in automated manufacturing applications. A brief quiz completes the activity.

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.

Learners observe that the melting of a solid and the freezing of its liquid occur at the same temperature. The melting point is an intrinsic property and is used to identify a substance.

In this animated object, learners examine the procedure used to determine the types of terminals on a single-pole, double-throw switch.

Learners examine the operation of an orifice plate flowmeter as it is used to make process control measurements. A brief quiz completes the activity.

Students view the equations used to determine the ac parameters of the transistor circuit.

Learners identify various therapeutic interaction strategies to be used when working with children and adolescents to enhance self-esteem, self-concept, self-worth, body image, and coping and communication skills.

This document is a visual and text description of preparing thread cutting tools, primarily used on a lathe.

2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a mounting wedge. A short quiz to test your ability to correctly read this information follows.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

In this learning activity you'll explore why the FTP protocol is often used to transfer data across the network and more importantly, why it should not be.

In this animated activity, learners examine the operation of a dynamic braking circuit used to quickly stop a motor.

Learners examine the labeling scheme used in ladder logic diagrams to identify components, wires, rungs, and rails. This activity includes self-check questions.

Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.
