Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
Weight- Volume Relationships: Saturated Density (Metric)
Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.
In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.
Weight-Volume Relationships: Introduction to a 3-Phase Diagram
In this animated activity, students read about weight-volume relationships within a given sample of soil or aggregate. They complete problems using a 3-phase diagram.
In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
In this interactive object, learners examine the five problem-solving steps of Define, Measure, Analyze, Improve, and Control. Some of the most common measures and tools are listed for each step.
Students read how the Plan-Do-Check-Act Cycle is used in problem-solving and process improvement. In an interactive exercise, students organize process improvement steps following this model.
Every speech starts with an outline. Knowing how to write one can make the difference between speech success and speech failure. In this module, we’ll explore what’s involved in creating an outline, demonstrate how to put one together, and give you examples you can use to create your own outline.
Solving Systems of Linear Equations Using the Addition or Subtraction Method (Screencast)
In a series of practice problems, learners use the addition or subtraction method to solve systems of linear equations, also called "simultaneous linear equations."
Matchless Manufacturing Company: An Exercise in Lean Thinking
In this interactive lesson, students use critical thinking to determine the best lean manufacturing initiative when solving problems for the fictitious Batchless Manufacturing Company.
