Item Response Analysis of the Continuous-Time Signals and Systems Concept Inventory
Abstract
Item response theory was used to analyze version 3 of the continuous-time signals and systems concept inventory with a pool of 1276 students at 7 schools. The resulting estimates of question difficulty and student ability provide important data used to evaluate the design of the exam and prepare for the upcoming revision to version 4 of the inventory.
