© 2016 by iSER, International Society of Educational Research.Geologic time scale is a very important concept for understanding long-term earth system events such as climate change. This study examines forty-three 4th-8th grade Native American—particularly Ojibwe tribe—students’ understanding of relative ordering and absolute time of Earth’s significant geological and biological events. This study also examines how these students understand the time scale of human history in relation to the longer geologic time scale of the earth and of the Ojibwe’s unique history. The students participated in a 15-hour lesson unit focused on the topic of climate change in Earth history. The two major sources of data included: 1) students’ relative ordering and written descriptions of ten given Earth historical events and 2) student groups’ placing of nineteen events on an absolute time line. Students’ relative ordering of ten given events and student groups’ placing of nineteen events on an absolute time line were analyzed quantitatively by descriptive statistics, whereas students’ written descriptions of the relative ordering of the ten given events were analyzed qualitatively. The results show that the students understand Earth’s geological events as three distinctive zones: near the beginning of Earth history, relative recent events, and between these two categories. The results also show that many students interpret general historical events in human history like “starting agriculture” through the lens of their own history and cultural viewpoints. This study shows that younger children have a general knowledge of major events in Earth’s history, such as continental movement, but cannot organize an accurate chronological order of these events. This study also shows that indigenous students’ knowledge of their own cultural and historical events affects their understandings of human history.

Environmental problems in Northern Cyprus: A descriptive statistical analysis and forecasting of air pollution and solid waste Günsel, Cansu Bahar; Taşıran, Ali Cevat; Sustainable Environment and Energy Systems (2016-8) Environmental problems have reached to global dimensions towards the end of the twentieth century. These problems are serious matters and gaining significance due to the threat on humanity: thinning in the ozone layer; global warming; greenhouse effect; natural balance deterioration; rainforest destruction; and air and water pollution. However, the most serious and globalized environmental problem for both developed as well as developing countries is the climate change. Mainly due to anthropogenic and indus...
Expert discourse on Turkish climate policy Üzelgün, Mehmet Ali; Rittersberger Tılıç, Helga İda; Department of Science and Technology Policy Studies (2007) This study renders the current frame of global climate change policies as a mirror of a new era, marked by surpass of the once absolute limits to growth towards humanity’s management and optimization of natural processes of the planet. A total of 24 interviews were realized with Turkish governmental and non-governmental experts on climate change, after application of a two-staged environmental attitude and policy questionnaire. Critical discourse analysis of interviews was performed to elaborate the results...
Integrated approach for sustainable development of energy, water and environment systems Krajacic, Goran; Vujanovic, Milan; Duic, Neven; Kılkış, Şiir; Rosen, Marc A.; Al-Nimr, Moh'd Ahmad (2018-03-01) The Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES) at the beginning of the 21st century have become a significant venue for researchers to meet, and initiate, discuss, share, and disseminate new ideas in various disciplines of sustainable development. In 2002, the first conference was organised in Dubrovnik, Croatia and since then, 10 more successful conferences were realised. Following the success of international conferences in Dubrovnik, the organizing committees...
European Union Basin-scale Analysis, Synthesis and Integration (EURO-BASIN) Salihoğlu, Barış(2014-12-30) EURO-BASIN is designed to advance our understanding on the variability, potential impacts, and feedbacks of global change and anthropogenic forcing on the structure, function and dynamics of the North Atlantic and associated shelf sea ecosystems as well as the key species influencing carbon sequestering and ecosystem functioning. The ultimate goal of the program is to further our capacity to manage these systems in a sustainable manner following the ecosystem approach. Given the scope and the international ...
Future climate change impact assessment of watershed scale hydrologic processes in Peninsular Malaysia by a regional climate model coupled with a physically-based hydrology modelo Amin, M. Z. M.; Shaaban, A. J.; Ercan, Ali; Ishida, K.; Kavvas, M. L.; Chen, Z. Q.; Jang, S. (2017-01-01) Impacts of climate change on the hydrologic processes under future climate change conditions were assessed over Muda and Dungunwatersheds of PeninsularMalaysia bymeans of a coupled regional climate and physically- based hydrology model utilizing an ensemble of future climate change projections. An ensemble of 15 different future climate realizations from coarse resolution global climate models' (GCMs) projections for the 21st century was dynamically downscaled to 6 km resolution over Peninsular Malaysia by ...
