Grouped Numerical Frequency Distributions - Definitions: Second in a Series
In this interactive object, learners read the definitions of terms associated with the construction of a grouped frequency distribution. A brief quiz completes the activity.
Automotive Electrical Systems: Effects of a Rheostat in a Series-Parallel Circuit.
Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.
Learners follow an EMT response at a restaurant involving a woman with slurred speech who has weakness on her right side. Students examine response procedures, resources, and medications.
In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.
Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
In this animated object, students view an explanation of how current, voltage, and the magnetic field strength of a series RL circuit change during five time constants. A brief quiz completes the activity.
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.
Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
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."
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 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.
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.
