Evaluation is very important for improving the quality of any software, including study materials used for teaching any specific topic. One of the parameters by which a study material’s quality can be measured is its degree of usability. This paper presents the usability analysis of an educational software that illustrates three algorithms which control the states and life cycle of processes in operating systems. It also describes the basic usability principles which serve to determine the usefulness of the user interface, learning curve, and the efficiency of the materials to achieve the defined learning objectives. Results indicate that the proposed tool is easy to use, and users found it very useful to support their learning process.
