The learner will learn how to understand, interpret, and correlate cardiac marker test results.

Learners will examine how cardiac markers are used in the diagnosis of cardiac disease.

Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.

In this interactive object, learners view a mind map of the symbolic interaction Approaches and answer questions about communication and symbols.

In this interactive object, learners read about sampling plans and practice using a sampling table.

Students test their skill at converting binary numbers to decimal numbers. Immediate feedback is provided.

In this interactive object, learners follow steps to assemble a wire feed welding torch or gun.

Students view a demonstration of the Current Divider Rule with the use of complex numbers. Examples are given.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

In this learning activity you'll test your ability to select the proper gage blocks when making a stack.

In this learning activity you'll examine a systematic method for converting a decimal number (base 10) into a binary number (base 2).

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.

In this learning activity you'll practice calculating a combined variation problem.

This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.

In this animated learning object, users study the factors that affect a pipe’s fluid flow and how those factors pertain to a numerical value (the Reynolds Number).

Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.

Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.

In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.
