A Dual Model of Computational Scaffolding and Technical Architecture for Educational Environments in Applied Sciences: An IoT-Based Architectural Instantiation

Educational environments for applied sciences often exhibit a disconnect between the pedagogical logic that structures learning activities and the technical architecture that implements them. In response to this problem, this study proposes a dual model that distinguishes a pedagogical architecture based on computational scaffolding from a layered technical architecture, while defining explicit coordination mechanisms between the two. The model is formulated at a conceptual level as a domain-independent architectural proposal and is instantiated in an IoT-based educational scenario to examine whether this articulation can be sustained coherently in a functional implementation. The empirical analysis does not address learning outcomes or pedagogical effectiveness. Instead, it evaluates the operational feasibility of the instantiation through usability evidence, concurrent load testing, and vulnerability analysis using OWASP ZAP. The results show that the proposed articulation can be implemented consistently under the tested conditions, with stable interaction flow and identifiable operating ranges. These findings support the architectural coherence and technical-operational feasibility of the analyzed instantiation, while leaving pedagogical validation of the model for future studies.
