This primer introduces the student to the proper use of the exponent (EE) function on a TI-86 calculator.

In this animated lesson, students read how reducing the thickness of a food is an important factor in cooling it. They also read FDA guidelines for food temperatures.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.

In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.

In this learning activity you'll test your knowledge of global rates for life expectancy.

The student takes a quiz on identification and operations of an engine lathe.

In this learning activity you'll explain how how Usability fits into User Experience Design.

Learners examine the seven most common barriers to effective listening and consider suggestions for how to overcome these barriers. This interactive object contains audio.

In this interaction the student is presented with 12 questions on vernier caliper parts identification.

This interaction tests the student's knowledge of parts on a radial drill press.

Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.

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.

In this learning activity you'll calculate the total inductance of a series circuit.

Students complete 10 practice problems.

The student identifies micrometer parts.

Describe the inverting op-amp configuration and calculate the circuit gain.

In this activity, we'll examine some common discontinuities associated with GMAW welding and review ways to prevent these problems from happening.

Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.

Students review logarithms as they pertain to electronics.

Students work practice problems to calculate the total resistance of a circuit. Feedback is provided.
