This document covers research in the field of e-learning and also tries to design course content that has properties od adaptivity. Developing e-learning systems, reaching adaptivity of learning content became the prime goal of every e-learning systems. We based our work on e-learning system AC-Ware Tutor and we will explain how adaptivity is developed in that system. We selected domain knowledge of college course „Programming I“ and design a map f concept that contains representative concepts for selected domain knowledge. Domain knowledge was designed on e-learning system, Moodle. Moodle is a free and open-source software learning management system. Developed on pedagogical principles, Moodle is used for blended learning, distance education, flipped classroom and other e-learning projects in schools, universities, workplaces and other sectors. Moodle doesn't have properties of adaptivity, but we tried to design course content using all functionality of system Moodle. mFor reaching knowledge-based adaptivity, course content is divided in five stereotypes, which represent the current level of student knowledge of course content and all course content is developed based on Bloom's taxonomy of knowledge. We wanted to use clusters so we could test their advantages and properties of adaptivity and because of that one part of course content is design using clusters and another part is design using sequence of lessons and tests, also in Moodle, following algorithms for generating course content.
