This thesis is concerned with the current situation and future developments of environmental education in Kosovo. Ecological problems in Kosovo have accumulated over decades as a consequence of the uncontrolled use of natural resources, a growing industrial production with a high level of pollution, and a lack of appropriate policies, laws, and institutions which could treat the problems. Air, water and soil pollution, waste problems and a severe loss of biodiversity are the main environmental threats. The integration of education for sustainable development (ESD) into all levels of education is one of the key priorities in Kosovo’s environmental action plan. However, at present it is not even known how environmental education (EE) is integrated in the country’s educational system. In a first step, all official textbooks and the national curriculum of Kosovo were thus scrutinized to identify how many and which environmental topics were included, in which subjects and grades they were taught, and which teaching approaches were used. In a second step, a written questionnaire was sent to a representative sample of biology, geography, chemistry and civic education teachers (overall 244 persons) to investigate the integration of EE in high schools (optional upper secondary education) in Kosovo. In a third step, in-depth interviews with 18 of these high school teachers were carried out to extend and deepen the discussion of their responses in the questionnaire. In a fourth step, a toolkit on EE / ESD was developed and introduced to nine high school teachers during a one-day inservice workshop. In a fifth step, structured observations were used to investigate the impact of the workshop on high school teachers’ performance in the classroom. Only 15 out of 130 books, most of them for biology teaching, included environmental topics. Environmental topics were most prominent in textbooks for grade 8, 10 and 12, whereas they were almost lacking at the primary-school level. Most environmental teaching units provided pupils with mere environmental / ecological information (91%). The other units aimed to raise pupils’ awareness of environmental values, critically reflected links between the natural, social and cultural environment, and demonstrated the importance of a healthy environment for human health, quality of life and sustainable development. They were most prominent in books for civic education. However, no environmental unit promoted pupils’ action competence. High school teachers were found to focus on various kinds of pollution and hazards of pollutants. Teachers’ choice of topics was highly relevant, place-based and linked to the experiences of pupils, but excluded sustainability issues such as the loss of biodiversity. EE was approached in three ways. The first approach critically reflected links between the natural, social and cultural environment, while the second approach was characterized by knowledge submission of environmental facts. The third approach aimed at capacity-building and, in the sense of ESD, understood learning as process-oriented, participatory and action-oriented. However, this approach was rather uncommon, most likely due to insufficient teacher preparation, classes that were too large (up to 50 pupils), and lack of little time (just one hour per week for EE). These constraints also restricted outdoor activities. Nevertheless, in view of the interviewees ideal EE would mean outdoor education, field work and other place-based, capacity-building practical experiences, and the development of critical thinking skills. Teachers were rather satisfied with the one-day inservice workshop and stated that they had learned something new. Moreover, they liked the new toolkit and thought it practicable for use in school. However, one year later it was obvious that without support from head teachers and colleagues the toolkit was not used in schools. The study found that before the workshop teacher talk accounted for more than 90% of all lesson time and pupil-initiated talk constituted less than 10% within a typical 45-minute lesson. After the workshop, teacher talk significantly decreased and pupil talk significantly increased. Moreover, pupils were found to be engaged in small activities suitable for ESD. In conclusion, there is a strong need for new textbooks on EE / ESD in Kosovo. However, without providing teachers with skills suitable for ESD, they will most likely continue to lecture and pupils will continue to only memorize the material. Moreover, novel teaching and learning approaches need engagement from credible leaders within the institutions. Especially head teachers should thus be incorporated in the implementation of new teaching material and approaches, and training courses on EE and ESD for school principles, administrators, and of course teachers, should be offered.

The raise of so-called artificial intelligence has made people believe that computers may some day be congenial with human beings. In the past computers were regarded as effective but soulless and unintelligent assistants to free humans from routine tasks. Computers were supposed to perform time-consuming but mechanical calculations. Today's computers are universal machines that can execute an almost unlimited variety of software. The increase of processing speed allows us to implement complex software which does not seem to have much in common with past computing machinery. In the field of education this awakened the desire to build algorithms which didactically support learners or even emulate human-like tutors. However, despite the apparent complexity of today's software, algorithms are step-by-step procedures which in their core are purely mechanical. So before introducing just another approach for technology-enhanced learning let me reconsider a seemingly naive but fundamental question. Given the nature of how computers work on the machine-level, can we emulate human-like tutors with computers? I believe that we can not because human beings are in possession of abilities which can not be implemented with algorithms due to their mechanical kernel and the formal systems on which algorithms are built. However, there exists a concept with which we can implement a mutual human-machine interaction that enables computers to at least adapt themselves to a learner. The result of this is what we call "adaptive systems". In this work, I present a method based on spatio-temporal data structures and algorithms which enable us to build technically simple but artificially intelligent self-adapting systems. Such systems can be utilized for technology enhanced learning but also for other fields related to human-machine interaction.
