The aim of this diploma thesis is to show the importance of competence-oriented teaching and to create teaching-tasks for secondary school-use in order to promote competences in a Psychology-class. This text depicts the long way from the mere concept of competences, culminating in the development and display of competences in students.Competence-oriented teaching is a new indicator, pointing towards a more output-oriented pedagogy. In order to understand this new concept, different terms of competences are distinguished and isolated from other concepts. Additionally, educational standards as well as competence-models describing social and personal competences are highlighted. Furthermore, a specifically developed model to promote factual competences combined with suitable descriptors is included; the main focus lies on the topic ?Clinical Psychology?. Using the individually developed competence-model on ?Clinical Psychology?, tasks are created matching this competence-model. These tasks have already been taught at a secondary international and bilingual school in Graz (GIBS). The resulting feedback was obtained via questionnaires, through which the arithmetic average and the standard deviation were elicited. Thus, it can be tested how students evaluate the tasks in terms of challenge, interest, usefulness, probability of success and comprehension.The discussion deals with the outcomes of this study and tries to answer the questions, whether these tasks truly promote competences or still need to be improved. Additionally, improvements and alterations are presented, in order to optimize the competence-oriented tasks.
