A model of educational processes called multidisciplinary gradual is presented, whose objective is to guide the teacher in the teaching-learning of STEAM educational activities using as a use case the topic of basic logic gates, which associates mathematical, algebraic, electronic, and logical knowledge, presenting the theory and strengthening it in practice. The topic of logic gates is not directly related to the middle-higher level educational plan; however, it is possible to apply and deepen it by relating the basic mathematical operations. The work describes the three stages that make up the model, achieving that students approach a problem or topic from different contexts, each discipline contributes its own knowledge and qualities, but not necessarily integrated in the common understanding of the problem, so that they develop the foundations to solve interdisciplinary and/or transdisciplinary problems. At the end, the results obtained by using this model with data from a control group and an intervention group are demonstrated with statistical analysis.
