In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.

In this animated activity, learners examine the fundamental operation of a logic probe that is used to detect logic signals in a digital circuit.

In this animated object, learners follow a process for troubleshooting digital integrated circuits on a printed circuit board using a logic probe.

The schematic symbols of logic gates used in digital circuits are shown.

Learners follow steps to trace logic signals from the inputs of several interconnecting logic gates to one output.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

Students view the layout and operation of a digital logic probe.

Learners will identify ladder logic diagrams and the logic functions they perform.

In this learning activity you'll be introduced to the eight most common logical fallacies commonly used in persuasive speeches.

Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.

In this learning activity you'll explore the differences between primary and secondary research.

In this learning activity you'll be introduced to the Ad Populum fallacy.

In this learning activity you'll be introduced to the either/or fallacy.

In this learning activity you'll be introduced to the Red Herring fallacy.

In this learning activity you'll be introduced to the Ad Absurdum fallacy.

In this learning activity you'll explore the Slippery Slope fallacy.

In this learning activity you'll be introduced to the Ad Verecundia fallacy.

In this learning activity you'll be introduced to the Post hoc, Ergo Propter hoc fallacy.

In this learning activity you'll be introduced to the Ad Hominem fallacy.

Learners examine eight different kinds of faulty logic or perception that interfere with critical thinking. They are superstition, ignorance, clustering illusion, false analogies, gambler’s fallacy, irrelevant comparisons, post hoc fallacy, and slippery slope fallacy. In an interactive exercise, learners identify ways to overcome these barriers.
