The master thesis discusses assessment of computer science knowledge, which students achieved with »Computer Science Unplugged« activities. First off we define what exactly computer science knowledge is and what the computer science concepts are. Then we get over to the modern approaches of teaching computer science, where the emphasis is problem solving. These approaches can be realized with »CS Unplugged« activities and Bebras tasks. The aim of the empirical part is to research whether assessment of knowledge, achieved with »CS Unplugged« activities, with Bebras tasks and similar are suitable. We check criterion validity through test and interviews with students and content validity with analyzing computer science experts' opinion. We also prepared practical suggestions for assessing knowledge achieved with »CS Unplugged« activities with help of Bebras tasks.
