Introduction to Records Management: Types of Records
In this interactive object, learners read an overview of records management and then classify records as "vital," "important," "useful," or "nonessential" in a drag-and-drop exercise.
The Mathematics of Buying: Putting It All Together
Learners tackle this interactive learning object after studying the mathematics of buying. This activity ties together the ideas of net cost, list price, trade discounts, cash discounts, net cost equivalent, and single discount equivalent, as well as the concepts of part, base, and rate.
In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.
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.
Parallel Circuit Analysis Practice Problems Part 1
In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.
2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a mounting wedge. A short quiz to test your ability to correctly read this information follows.
Users of this learning object evaluate the early online experiences of four hypothetical students and record the lessons that can be learned about what to do and what not to do to create effective online learning environments.
