In this animated object, learners examine the basic types of limit switches and how they are used.

Learners examine seven basic human limitations that prevent people from seeing or understanding the world with total clarity. In an interactive exercise, learners identify ways to overcome those barriers to critical thinking.

Learners follow steps to establish the lower and upper limits in a spreadsheet.

In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.

Learners examine the circuitry in a DC variable speed drive that protects the rectifier diodes and motor windings from being damaged due to excessive current.

In this animated and interactive object, learners follow oral directions in the workplace. They complete their task within a time limit. This object has audio content.

Learners click on the root word of a medical term in the left-hand column and drag it to its definition in the right-hand column. There is a time limit, so students will need to train themselves to recognize these root words quickly. Students may repeat the activity as often as they wish. A total of 74 terms are given in random order.

The learner will explore basic human limitations that create barriers to critical thinking including selective thinking, false memories, and perceptual limitations.
