Engineers must be trained to integrate theory and practice to develop the necessary competencies to face the challenges of the professional environment. This article presents the educational strategy called The Triangle of Effective Learning, which the author conceived and implemented for several years in the Electrical Electronics degree program at the School of Engineering of UNAM. Its main objective is to link theory, simulation, and practice effectively, promoting comprehensive, applied, and effective learning.

The strategy is structured in three interconnected phases: theory, simulation and practical applications. In the first phase, students reinforce their understanding of fundamental theoretical concepts through manually solved examples. This initial stage favors the development of essential analytical and mathematical skills, laying a solid foundation for the following phases. Later, in the second phase, students employ simulation tools to model more complex systems and visualize their behavior. This stage fosters a broader and more dynamic understanding of theoretical concepts, promoting the validation of their knowledge interactively. Finally, the third stage consists of practical projects in which students apply their knowledge in a real physical environment. Creativity and autonomy are promoted in this stage, allowing students to consolidate their learning while designing and developing concrete technical solutions.

An outstanding aspect of this strategy is its flexibility. Students can begin their learning in any of the three phases and progress to the others, generating a continuous learning cycle that adapts to the pace and style of each participant. In addition, the progressive approach by levels of complexity ensures that knowledge is reinforced gradually, providing a personalized and effective learning experience.

The results of this methodology are convincing. Successful cases have been documented through projects developed by students, demonstrating the strategy's effectiveness in improving the understanding of theoretical concepts, strengthening practical skills and increasing satisfaction with the learning process. The surveys positively impact academic performance and prepare students to face technical problems in the professional field.

Special attention is paid to key technical aspects to ensure the operability and reliability of the projects and circuits designed during the learning process. These include validating system operation, optimizing design, identifying and resolving common errors, and reliability testing. These measures strengthen hands-on learning and ensure that students gain experience in the advanced design and prototype development stages.

The effective learning triangle strategy is presented as a comprehensive educational tool that links theory, simulation and practice sequentially and methodically. Its implementation fosters active learning, strengthens technical competencies and prepares students to face the challenges of the professional environment with greater confidence and capacity. This strategy constitutes an innovative educational model that contributes significantly to the training of professional engineers.
