The Extended Contact and Channel Approach (Extended C&C²-Approach) is a framework for analyzing and modelling of Embodiment Function Relations (EFR) in product engineering. Despite its potential, many students and professionals face challenges in understanding and applying its core principles and extensions. This paper presents and evaluates a modular training concept integrating short theory inputs, collaborative active-learning modules, and guided practice within the Live-Lab IP24/25 – Integrated Product Development. Results from a mixed-methods evaluation demonstrate that while foundational concepts are effectively taught, challenges remain in teaching advanced topics like the Designation Guideline and Functional Delimitation. This paper presents a validated instructional framework that connects the Extended C&C² modeling process to specific learning objectives and long-term behavioral outcomes. This framework supplements existing engineering education formats by explicitly focusing on EFR-oriented modeling proficiency. Limitations include a single-institution sample and limited statistical power, suggesting future multi-site comparative studies.
