Metacognition is the awareness one has about his/her thinking process and how he/she is able to control these processes. Metacognition strategies are the sequential processes individuals use to learn how to control themselves and to reach a goal. They significantly help the arrangements and control of the individual learning. In all educational processes, supportive teaching for metacognitive skills should be done to achieve the goals set in the teaching of geography. Students can gain metacognitive skills with lessons in geography based on the constructivist approach. In this study, the relationship between geography teaching and the concept of metacognition, which is one of the basic approaches that directs the activities of thinking in the teaching of geography, is discussed. © 2011 Academic Journals.Öğe Gifted students' attitudes towards environment: A case study from Turkey(2011) Aydin, F.; Coskun, M.; Kaya, H.; Erdönmez, I.The purpose of this research is to examine the attitudes of primary students that study at gifted students' school (BILSEM).

We aimed to investigate the distribution of seropositivity of HBsAg, anti-HBs, anti-HCV and anti-HIV according to years, genders and age groups in patients who applied to our hospital. Methods: Results of HBsAg, anti-HBs, anti-HCV and anti-HIV tests performed during 2015-2019 in our hospital were reviewed retrospectively. 77,562 serum samples were studied for HBsAg, 45,045 for anti-HBs, 73,223 for anti-HCV and 71,061 for anti-HIV of a total of 266,891 samples. The tests were analysed using chemiluminescent microparticle immunoassay (Architect i 1000, Abbott, USA) and electro-chemiluminescence immunoassay (Cobas 6000,Roche Diagnostic GmbH, Germany) methods. Data were collected from the database of our hospital. Data were analyzed using the SPSS software ver. 24.0. Chi-Square (?2) analysis and Fisher’s Exact test were used for comparison of categorical variables. The p<0.05 was considered statistically significant.Results: HBsAg, antiHBs, anti-HCV and anti-HIV positivity were 2.3 % (1,808/77,562), 46.6% (20,975/45,045), 0.6% (456/73,223) and 0.05% (35/71,061) respectively. Of the 1,808 patients were positive for HBsAg, 55% were males, 45% were females. Of the 456 anti-HCV positive patients, 63.6% were females and 36.4% were males. When assessed by age groups, HBsAg positivity was found to be the highest in the age group 31-50 (38.1%) and lowest in the age group ? 18 (0.6%). Anti-HCV positivity was found to be the highest in the age group ?65 (32%) and lowest in the age group ? 18 (2%). All patients who were found to be anti-HIV positive were male and the highest positivity rate was between the ages of 19-30. Conclusion: Our HBsAg, anti-HBS, anti-HCV and anti-HIV results were found to be similar with the country statistical data. There was significant difference in the seropositivity of HBsAg (p<0,001), anti-HCV (p<0,05) and anti-HIV (p<0,001) during the measurement period. © 2022,Turk Hijyen ve Deneysel Biyoloji Dergisi. All Rights Reserved.Öğe Investigating the seismicity of urban areas using definite parametres: City center of Karabuk(Peter Lang AG, 2019) Aydin, F.; Dönmez, Y.Many factors are considered in the planning of urban areas. One of these factors is earthquake zones. In this study, geology, distance to fault lines, information about topography and groundwater, with the help of geographic information systems, is aimed to determine suitable settlement areas. When the earthquake damage risk map of the study area is examined, the middle and western sections of the region are High Risk, the middle sections of the region, along the western boundary, the south section and, to a lesser extent, the eastern section, High Risk, the south-eastern part of the western part is less risky and the eastern part of the zone is the least risky area. In this study, the analysis was conducted by using ArcGIS 10.1 Geographic Information System software, an earthquake risk map was constructed and measures to be taken against the damage caused by a possible earthquake were assessed. © Peter Lang AG 2019.Öğe INVESTIGATION OF ALTERNATIVE TOURISM TYPES AND SIGHTS VIA GEOGRAPHIC INFORMATION SYSTEMS: THE EXAPLE OF SAFRANBOLU(Copernicus Gesellschaft Mbh, 2017) Aydin, F.; Cepni, O.; Turgut, T.In this study, alternative tourism types and sights belonging to Safranbolu were identified through Geographic Information System (GIS) tools. In this manner, most favorable tourism activities, which are specific to field, and evaluation factors of these activities were determined. Suitability classification values of these factors were charted by receiving opinions from experts. Natural and cultural properties of study area were determined in the light of evaluation factors and a database was set via GIS. This database was examined according to evaluation factors of the activities and the most suitable and conditional suitable areas were determined. In this study, it is aimed to carry out the suitable place analysis for alternative tourism types of Safranbolu, which is a tourism town, such as riding, mountain biking, camping, trekking. 486 km(2) area for riding, 319 m(2) for trekking, 209 km(2) for mountain biking and 148 km(2) for camping were figured out as suitable. These results reveal that tourism activities should be more professionally organized in order to apply alternative tourism types such as riding, mountain biking, camping, trekking.
