In this learning activity you'll identify examples of Eric Berne's theory on transactional analysis.

Students read how to record relevant information on a test tray evaluation form. They enter their own analysis of the data in a practice exercise.

In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.

In this learning activity you'll test your knowledge of the different types of steel rules as well as how to use and read them correctly.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

In this learning activity you'll practice entering the plural present, plural present perfect, past, and past perfect forms of verbs.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.

In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Learners examine how metal detectors function. This object includes animation and sound.

In this learning activity you'll discover how to evaluate a problem statement using both the MEA and the IP Techniques.

In this learning activity, you'll identify behaviors of the three ego states and practices their use.

Learners follow a step-by-step explanation of how to test fuses and circuit interrupting devices.

In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.

The approach to dc circuit analysis is presented to the learner. The approach is demonstrated for the student.

This general shop safety test assesses the student's knowledge of acceptable safety practices associated with the machine shop.

In this interactive learning object, learners study the parts of the brain and then test their knowledge in a drag-and-drop exercise.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.
