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.

In this learning activity you'll review different math symbols and identify them in a matching exercise.

In this learning activity you'll discover how the visual perception concept influences your understanding of ambiguous figures.

Learners convert a number from standard form to engineering notation.

Learners examine the relationship of individual parts in an assembly drawing. Assembly drawing notes, fabricated and purchased parts, and sectional views are explained briefly.

In this learning activity you'll read about Colombia and view a map.

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

Learners examine how chemists use moles to "count" atoms by weight. Examples are given.

The schematic symbols of logic gates used in digital circuits are shown.

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

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

Learners view a demonstration of Kirchhoff's Voltage Law using complex numbers for an ac circuit.

Students read and test themselves on the conditions that cause specific acid/base imbalances.

In this animated and interactive object, learners follow two methods for converting a hexadecimal number to a decimal number. They test their knowledge in exercises at the end of the learning object.

Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.

This primer introduces the student to the correct method of entering complex numbers in both rectangular and polar form.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.
