In this interactive exercise, learners label the components of a workstation, a Windows desktop, and an application window.

Learners examine the method used to calculate the mass percent of an element in a compound. Three examples and one problem illustrate the method.

Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.

Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.

In this animated activity, learners listen to instructions for simplifying a complex fraction by finding the least common denominator. This learning object requires a computer that is equipped with speakers.

In this learning activity you'll explore three common network protocols that computers use to communicate in a network.

Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.

Learners examine the theory of operation for a combustible gas detector. A brief quiz completes the activity.

Learners view the operation of the 7485 integrated circuit magnitude comparator in this animated object. A quiz completes the activity.

Learners compare animations of analog and digital data signals. A short quiz completes the activity.

Learners read about nonverbal communication. In a drag-and-drop exercise, they evaluate photos of people interacting and determine if the behaviors shown interfere with communication or enhance it.

Students review the rule for pluralizing compound nouns. They then complete an exercise.

The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.

In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.

Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.

Learners follow steps to size an interior grease interceptor for a commercial dishwasher. This animated learning object presents plumbing code requirements and industry standards. A brief quiz completes the activity.

Compare the behaviors and situations that interfere with effective communication in the workplace with those that enhance listening skills and career performance.

Learners examine the complex number function to convert real and imaginary coefficients into a complex number.

Users read about how course competencies relate to program outcomes. They listen to the testimonies of three students who describe learning activities that prepared them for the world of work. In a matching exercise, learners distinguish between course competencies and program outcomes.
