Overview

Quasi-experimental study reveals enhanced conceptual mastery among engineering students using an AI-guided platform, suggesting cognitive offloading compensates for weaker prior math preparation.

Key Points

  • To evaluate whether pairing an AI-driven Socratic agent with dynamic visual offloading helps engineering students overcome mathematical bottlenecks to develop conceptual mastery in Signals and Systems.
  • Quasi-experimental evaluation conducted with 192 students comparing an experimental cohort to a historical control.
  • Implemented a dual-component architecture combining a dynamic visual platform with a RAG-enabled Socratic Pedagogical Agent across four stages: Perception, Exploration, Synthesis, and Transfer.
  • Assessed student performance across three isolated competency components: Procedural Fluency (55%), Analytical Derivation (25%), and Conceptual Mastery (20%).
  • Despite presenting with a significantly lower baseline in mathematics (p < 0.001), the experimental group reached parity with historical controls in overall course grade (p = 0.724), Procedural Fluency (p = 0.312), and Analytical Derivation (p = 0.362).
  • The experimental cohort achieved significantly higher performance in Conceptual Mastery compared to controls (p = 0.004, Cohen's d = 0.42).
  • Qualitative assessments demonstrated high student acceptance, with participants highlighting the value of exploring parameters in a safe-failure environment over direct computational shortcuts.
