Abstract

This dissertation explores the design and development of a digital learning environment for teaching the binary system, employing the microlearning methodology. The primary objective of this research is to address the instructional challenges encountered by Vocational High School (EPAL) Informatics students during their transition from the fundamental concepts of the 10th grade to the advanced requirements of the nationally examined course "Computer Networks" in the 12th grade. The necessity of this intervention is grounded in the fact that mastering the binary system and numerical conversions constitutes a critical cognitive prerequisite for managing IP addressing and subnetting. Furthermore, familiarity with encoding standards and Boolean Algebra is es-sential for understanding the OSI model, error control, and data flow at the Physical Layer. To ensure interdisciplinary consistency, the proposed material is structured into four autono-mous micro-lessons, covering bit logic, number system conversion techniques, digital data representation (ASCII, Unicode), and logic gates. The selection of microlearning as a pedagogical model aims to reduce cognitive load and en-hance information retention through short, targeted modules. In this manner, knowledge is built incrementally, enabling students to develop necessary digital competencies in a flexible way. This work culminates in the creation of a modern digital tool that functions not merely as a means of information transfer, but as a supportive mechanism that enhances teaching prac-tices and effectively prepares students for the demands of higher education.
