The student reviews primary and secondary groups and takes a short quiz.

Learners examine the use of the reciprocal key on the TI-83 Plus calculator to determine parallel resistance.

In this learning activity you'll read key words that direct you to add, subtract, multiply, or divide.

In this interactive object, learners experience how the three primary flight controls allow a pilot to determine the motion of the airplane during flight.

The use of the reciprocal key on the TI-86 scientific calculator is demonstrated in the solution of parallel resistors.

In this module, we'll be introducing you to SIPOC, a powerful tool that can help you improve your business processes. It's a high-level process mapping tool that helps you identify the key components of a process and how they relate to each other. SIPOC diagrams are often used in Six Sigma and Lean methodologies, but they can be useful for any process improvement initiative. We’ll explain the key SIPOC components and demonstrate how to build one. Then, we’ll walk through a few scenarios and let you build your own.

Learners rank the most efficient ways in which workers retain information and create their own plan for improvement.

In this learning activity you'll explore and practice the first step in normalizing a database.

In this learning activity you'll match definitions of motivational terms with terms and concepts found in a puzzle.

In this learning activity you'll practice using the keys on the Casio fx-260 Solar Calculator.

In this learning activity you'll practice identifying keys on the Casio fx260 Solar Calculator.

In this learning activity you'll explore the Marvel PCII keys.

In this activity you'll practice designing a table in second normal form.

In this learning activity you'll define the keys on the Casio fx-260 Solar Calculator.

Explore what referential integrity is, why it's important to reliable data organization, and learn how it enforces constraints.

In this video, we’ll explore how to cut a keyseat.

In this animated object, students examine the shades that result from mixing primary and secondary colors. Color tone and level are also defined.

The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.

Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.

Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using if-then-else, calls, unconditional jumps, and counters in this learning activity.
