Project
Through our actions we aim to reach teachers of physics and other sciences to support their work starting from the base level of defining what the student are tought. We aspire to see more common use of ICT, interdisciplinary knowledge and students working in groups during lessons in Polish schools. We want to achieve that by: - spreading good practices of teaching basing on experience of our partners, - creating suitable conditions for the teachers to exchange their experiences, - preparing an innovative teaching program for Polish schools using the method of project-based learning, - working on exemplary educational projects focused on connecting specific subjects from core curriculum, - preparing lesson scenarios incorporating elements that incentivize students to be more active, - preparing a catalogue of good practices of teaching physics in lower and upper secondary schools in France and the UK, making teachers more interested in using modern technologies, - including the space context into physics lessons. http://sat.cbk.waw.pl/en/
Project
EOTiST aims to enhance the S&T capacity of the Space Research Centre of the Polish Academy of Sciences (CBK PAN) and to achieve excellence in research of EO products’ assimilation in the ecosystem assessment and monitoring by starting close collaboration with 3 European centres of excellence: CERTH, CREAF, CNR. Monitoring of ecosystem services using terrestrial methods is very expensive or sometimes even impossible, especially if we want to cover entire regions or the world. Thanks to satellite data, we can provide new information about ecosystems in a continuous manner, both in space and time, determine the dynamics of changes taking place in ES delivery and create forecast models for the development of a given area. This is of particular importance in the sustainable management of resources. Specific goals are to be pursued: - Enhance S&T capacity of CBK PAN - Upgrade research profile of the CBK PAN and the profile of its staff by mobilizing and training of personnel (workshops, staff visits, and on-line courses, etc.) - Increase research excellence and stimulate innovation in CBK PAN - Achieve sustainable progress and future development for the today’s seed group in CBK PAN. - Promote the involvement of early stage researchers in the CBK PAN. - Develop joint research initiatives and projects. - Improve proposal preparation and management/administration skills in the CBK PAN.
Project
The general objective of the project is to explore how cultural ecosystem services are formed and delivered in urban area. It aims to respond to the following research questions: 1. Are the citizens of urban and suburban areas interested in contact with nature and what does “contact with nature” actually mean for them? 2. What are spatial, ecological and social drivers of CES delivery in urban areas? 3. What are the differences in CES formation and delivery along the city-core – peri-urban axis? 4. Do forest and other semi-natural areas located at the border of the city attract visitors searching for wilderness, or do they share the same functions with urban parks in the city center? 5. What are relations between attitudes toward nature, CES consumption and the level of ecological knowledge of visitors to green areas? 6. What is the role of green areas managers and providers of recreational and educational services in CES delivery?
