Scaffolded Game-Based Simulation Design for Conceptual-Operational Transition in Railway Education

Railway education has traditionally relied on high-fidelity simulators that emphasize procedural and operational skill, while game-based applications in the transport domain remain limited and are more often used for persuasion or data elicitation than for conceptual learning. This paper addresses the resulting gap between theoretical understanding and practical competence, observing that novice learners frequently require instructor guidance to grasp the principles that underlie operational tasks. To address this, it proposes Scaffolded Game-Based Simulation (SGBS), an intermediate learning layer that situates conceptual instruction between theory and full operational training.

The authors distinguish learning-oriented game applications from high-fidelity simulations along four dimensions: system complexity, decision-making structure, feedback, and explicitness of principles. Simplified environments make underlying principles more visible, and the framework draws on Anderson and Krathwohl's revised taxonomy to structure progression. The proposed three-layer SGBS model uses progressive complexity, bounded decision-making, and explicit feedback to move learners from conceptual understanding toward operational skill. A flank protection scenario serves as the illustrative example.

The framework is presented as a conceptual contribution and has not yet been empirically validated; the authors state this limitation explicitly. The paper's grounding draws on serious games research, cognitive load theory, scaffolding theory, and railway human factors, and it situates the proposal among recent simulation and virtual reality applications in railway signaling, traction power, and wagon logistics training. The scope is therefore theoretical and design-oriented, with the primary claim being that a scaffolded intermediate layer is needed and can be structured in principle, pending future testing with learners.
