Abstract:

Engineering education increasingly demands pedagogical approaches that connect conceptual understanding, modeling, experimentation, and the effective materialization of technical solutions. However, in many engineering science and applied engineering courses, students are often able to analyze and simulate a system without being equally prepared to build, integrate, validate, and technically justify a functional implementation. This limitation reveals a formative gap: the transition from theory to simulation and practice does not always culminate in a sufficiently structured understanding of how an academic solution is physically realized.

The Effective Learning Triangle (ELT), previously developed by the author, is a pedagogical framework that organizes engineering learning through the articulated relationship among theory, simulation, and practice. Building on this framework, this paper proposes a conceptual and methodological extension that explicitly incorporates prototyping as a formative dimension emerging from the simulation-practice relationship. In this perspective, the prototype is not treated as a secondary deliverable or as mere end-of-course evidence, but as a pedagogically meaningful stage in which students transform a conceived and modeled solution into a functional, stable, verifiable, and academically sound implementation.

This extension also highlights the educational relevance of proper assembly, understood not simply as manual execution but as a process involving integration decisions, physical organization, staged verification, experimental validation, discrepancy analysis between expected and observed behavior, fault detection and correction, operational stability, and technical communication of results. The study follows a qualitative, reflective, and proposal-oriented approach grounded in the systematization of teaching practice and in the analysis of academic projects in which students progress from initial design ideas to the physical implementation of engineering systems and devices.

From this analysis, the Progressive Integration Methodology for the Academic Prototype (PIMAP) is proposed as a structured pathway to guide idea conception, integration planning, minimum functional prototype validation, assembly presentation, and final technical communication. The proposal establishes an intermediate academic standard between tolerated improvisation and the inappropriate expectation of industrial-level development in undergraduate contexts. The main contribution of this paper lies in extending the ELT by recognizing prototyping as a constitutive dimension of engineering learning and in providing a transferable conceptual and methodological basis for guiding and assessing prototype-based learning in undergraduate engineering education.
