Abstract: Competencies and competency models are key aspects of modern education and play a decisive role in the design of lessons. They provide teachers with a framework to define the skills and knowledge that students should acquire. Competency-based education is particularly relevant in a subject like computer science, which is rapidly evolving and where practical skills are often just as important as theoretical understanding. It is therefore not surprising that in various educational systems, competency orientation plays a role in educational standards or curricula for computer science. When looking at international models, the different forms and structures used to represent them are striking. For example, a three-dimensional competency model is defined in the educational standards for computer science teaching of the German Informatics Society. Switzerland's Curriculum 21 describes a progressive development of competencies that together lead to an overarching competency. Austria's curricula also rely on competency orientation, whereby lists are used for enumeration. A structured and standardized form of presentation is required to be able to carry out analyses or comparisons. A graph-based approach, in which competences are represented as nodes and their interdependencies as edges, helps to avoid the differences. This allows new metrics to be measured and compared, and practical information such as learning paths with start and end points can also be read out.In this presentation, some competency models of computer science and of digital education will be compared, advantages and disadvantages will be discussed, and the graph-based approach will be presented, with the help of which differently structured models can be compared and analyzed.

Saturn, with its distinctive ring system, is one of the most impressive planets in our solar system. Roland Brockers will take the audience attending his public lecture on Thursday, 5 June (5 p.m., Lecture Hall 1, University of Klagenfurt) on an exciting journey to the ringed planet with the largest number of known moons in the solar system. Roland Brockers is Professor of Modular Robotic Systems in the Control of Networked Systems group and a researcher at NASA’s Jet Propulsion Laboratory / California Institute of Technology in California. This public lecture continues his series of Space Exploration Lectures delivered during his teaching visit to Klagenfurt.“Not only is the sheer size of this gas giant and the breathtaking beauty of its rings mesmerizing, it also holds the record for the planet with the most known moons – many of them covered by ice, some of them with a subsurface ocean and a moon with an atmosphere denser than Earth: Titan”, says Roland Brockers, who will be returning to the University of Klagenfurt in early summer to offer courses on robotic visual perception for students of robotics and information and communications engineering. However, it is not only students who stand to benefit from his stay; anyone interested in space exploration is welcome to attend his public lecture: “In this talk, we will examine Saturn, the history of its exploration, and have a look at its unique moons that may hold key ingredients for past or present life, making them prime locations for our next robotic explorers,” he announces.
