This paper describes the design, construction, and evaluation of an instructional module for public school engineering students in grades 10, 11, and 12. The module is designed to teach students how to write controller programs in Ladder Logic, the language of the Programmable Logic Controller (PLC). The module consists of a combination of lecture and guided practice activities that require students to wire, program, and build with PLCs and robotic components presently common in public school engineering courses. This module was created as a result of attending a Summer Research Experiences for Teachers program at Texas A&M University in 2016. The instructional module was delivered to two classes in digital electronics. A pre-instructional assessment was used to measure prior learning, and then instruction commenced. Each class worked in teams of four to create Ladder Logic programs for the simulator, upload the code to its PLC, and operate the machine. After successfully programming and operating the machine, students were administered a post-instructional assessment and the results of the two instruments were compared. A one-tailed, paired sample t-Test indicated a statistically significant (a < .05) increase in student understanding.
