Overcoming Barriers to Critical Thinking: Being Human
The learner will identify ways to overcome barriers to critical thinking and problem-solving including false memories, personal biases and prejudices, and physical and emotional hindrances.
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."
In this animated activity, learners read the definition of a parallelogram and then find the perimeter and area of parallelograms in practice problems.
Automotive Electrical Systems: VAT-40 Starting System Test
In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.
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.
In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.
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.
