Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
Barriers to Critical Thinking: Faulty Logic or Perception
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.
This animated lesson an exercise that enables students to design a ladder logic circuit using a drag-drop function to cause the cylinder of a hydraulic circuit to extend and retract.
