In this learning activity you'll follow the process of converting digital data into a series of analog signals.

In this simulation, learners follow a series of steps to operate the Marvel Saw PCII in the manual mode. This activity includes a video clip.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this learning activity you'll explain how voltage and resistance in a series circuit affect current flow.

Explore the history behind today's eLearning best practices in this introduction to our design principles series.

Learners review a graphic summary of the three series of reactions that occur during cellular respiration and the net energy (ATP) yield of that process.

In this interactive object, part 3 in a series, learners follow the steps of the “mathemagician” to examine four numerical curiosities: What’s Special About 1089, Perfect Squares: 1089 and 9801, The Mathematical Significance of 1776, and The Calculator Number Game. The learner will also study six number patterns and look at one remarkable table. Immediate feedback is provided.

In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.

Learners read a brief introduction to in-control and out-of-control conditions and view a series of distribution curves. This is a follow-up to the learning object titled "Quality Basics: Variation."

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

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.

In a series of interactive exercises, learners identify the parts of a URL, a Web site, and an e-mail memo. Students are given their score at the end of the activity.

In this interactive lesson, learners read the rules for filing business records and then test their knowledge in a series of exercises. Immediate feedback is provided.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.

In a series of practice problems, learners use the addition or subtraction method to solve systems of linear equations, also called "simultaneous linear equations."

In this learning activity you'll apply chunking to memory formation and retrieval. You'll test your ability to memorize a series of numbers with and without the chunking method.

This animated object allows students to examine the four steps used to reduce a complex circuit to a simple series circuit.

Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.

Learners answer 14 questions about series-parallel DC circuits.
