For this reason, the current research aimed to illustrate how to intertwine mathematical modeling with an environmental issue that recruits waste management (e.g., reuse-recycle-reduce) to live an environmentally friendly lifestyle. Through a case study research, 6 seventh-grade students (3 females and 3 males; aged 13-14) voluntarily participated in the research. The researchers videotaped and analyzed all interactive learning processes to elicit the students’ environmental dialogues. The results indicated that the interdisciplinary mathematical modeling afforded the students to acquire the targeted environmental concepts/issues and somewhat supported their arguments. Since the current research illustrates an alternative pedagogy to integrate science/environmental education into mathematics, it may be used to facilitate dissemination and applicability of the STEM education. </style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">412-424</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Muammer   Çalık</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">USING THE COVID-19 PANDEMIC AS A SOCIOSCIENTIFIC ISSUE TO SUPPORT THE SCIENTIFIC HABITS OF MIND</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">content knowledge</style></keyword><keyword><style  face="normal" font="default" size="100%">COVID-19 pandemic</style></keyword><keyword><style  face="normal" font="default" size="100%">pandemic process</style></keyword><keyword><style  face="normal" font="default" size="100%">scientific attitude</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2021</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2021</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2021/457-1634799659.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">79</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The COVID-19 pandemic has affected all people without discriminating any border, country, race, ethnicity and so forth (Arroio, 2020). Thus, it has acted as a new playmaker in recognizing the importance of education and social justice. As stated by Usak et al. (2020), we, as educators, should pay more attention to the development of students’ awareness and scientific attitudes. Thus, they are able to think, understand, decide and make an action about any urgent event or &quot;forced&quot; transition, i.e., the pandemic process (Rodgríguez et al., 2021). Unfortunately, the COVID-19 pandemic seems to have generated a climate of fear for scientific advances and mass vaccination as well as regulations on lockdown, socialization, and hygiene. </style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Editorial</style></work-type><section><style face="normal" font="default" size="100%">694-699</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Sibel Er Nas</style></author><author><style face="normal" font="default" size="100%">Muammer   Çalık</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A CROSS-AGE COMPARISON OF SCIENCE STUDENT TEACHERS’ CONCEPTUAL UNDERSTANDING OF SOIL EROSION</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">conceptual understanding</style></keyword><keyword><style  face="normal" font="default" size="100%">cross-age</style></keyword><keyword><style  face="normal" font="default" size="100%">mental model</style></keyword><keyword><style  face="normal" font="default" size="100%">science student teacher</style></keyword><keyword><style  face="normal" font="default" size="100%">soil erosion</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">October/2018</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2017/457-1540319925.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">76</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The relevant literature has shown that student teachers hold alternative conceptions of soil erosion. Even though Turkish science student teachers are expected to teach the concept of ‘soil erosion’ in lower secondary schools (grades 5-8), none of the earlier studies have explored their conceptual growth and/or mental models throughout a 4-year undergraduate program. Indeed, science (student) teachers, who play a pivotal role in teaching the sustainability of soil as an environmental heritage, are able to transfer their environmental knowledge and mental models to younger generations. Therefore, the aim of this research was to elicit science student teachers’ (SSTs) understanding of soil erosion. In a cross-age comparison, the sample of the research was comprised of the first-year (n=54), second-year (n=62), third-year (n=60), and fourth-year of a four-year science education program (n=65), a total of 241 SSTs, enrolled at the Department of Science Education in Karadeniz Technical University in Turkey. A questionnaire with 4 open-ended questions and semi-structured interviews were used to collect data. The results indicated that the majority of the SSTs confused the concept of ‘soil erosion’ with the one ‘landslide’. For this reason, the current research suggests the development of analogies and computer simulations to overcome this confusion.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">601-619</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Muammer   Çalık</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A DILEMMA IN UPPER SECONDARY TEACHER EDUCATION</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">teacher education</style></keyword><keyword><style  face="normal" font="default" size="100%">teaching competency</style></keyword><keyword><style  face="normal" font="default" size="100%">upper secondary school</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">November/2012</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2014/457-1413728750.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">47</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">There is a consensus about primary and lower secondary teacher education in that Faculty of Education is actively responsible for preparing them for their future teaching careers. However, a struggle between Faculty of Science and Faculty of Education has still been continuing to come up with an agreement for upper secondary teacher education. For example, the undergraduate students attend subject matter courses in Faculty of Science and then take pedagogical (content knowledge) courses in Faculty of Education at most of the developed countries, i.e. USA, Germany, England. Despite the fact that this program seems to have been time efficient for pedagogical courses, this has lacked of motivating them to become the upper secondary teachers. In fact, motivation and enthusiasms to be a teacher play a significant role to learn how to teach.</style></abstract><work-type><style face="normal" font="default" size="100%">Editorial</style></work-type><section><style face="normal" font="default" size="100%">5-5</style></section></record></records></xml>
