The current study is an educational design research on the design, implementation and evaluation of a graduate course that is aimed at improving science teachers’ theory and pedagogy of argumentation in science education. It was aimed to describe the educational design process of a graduate course with a reflexive approach. In addition to the design process, the science teachers’ instructional practices in argumentation based lessons were explored in the study. The participants were 1 elementary school science teacher, 2 high school science teachers and 4 graduate students, who were all pursuing a graduate degree in science education. The study comprised two parts: The first part reported the design, implementation and evaluation of a graduate course, named as “Argumentation in Science Teaching and Learning”. Educational design research methodology was applied to achieve the professional development of science teachers. The audio-recorded course sessions, post-interviews, and participants’ written materials were constituted the data. The results revealed the elements of an effective design solution. Moreover, the results demonstrated that the design solution contributed to the participants’ understanding of argumentation, and all participants had meta-level knowledge of argumentation in science education. The second part was the exploration of the participants’ instructional strategies on argumentation based lessons. Data sources included the participants’ video-recorded classroom practices, audio-recorded reflections, post-interviews, and participants’ written materials. The findings revealed six typology named as argumentation specific pedagogical knowledge, meta level pedagogical knowledge specific to argumentation, general pedagogical knowledge, meta level general pedagogical knowledge, meta-strategic knowledge, and meta-strategic knowledge specific to argumentation.

Mode-method interaction: the effects of inquıry vs. expository and blended vs. face-to-face instruction on 9th grade students’ achievement in, scıence process skills in and attitudes towards physics
Çetin, Ali; Özdemir, Ömer Faruk; Department of Secondary Science and Mathematics Education (2013)
The purpose of this study is to find out the main effects of instructional modes (blended and face-to-face), teaching methods (inquiry and expository) and the interaction effects between them on 9th grade students’ physics achievements, science process skills, and attitudes towards physics. To achieve this purpose, 2x2 factorial design with four treatment groups were constructed, blended inquiry (W-INQU), blended expository(W-EXPO), face-to-face inquiry (INQU), and face-to-face expository (EXPO). Two web en...
Integrating STEM Education: Perceived barriers and facilitators
Taşcı, Duygu; Öztekin, Ceren (null; 2017-05-21)
The purpose of this research is to uncover obstacles science teachers face regarding integrating STEM in their science course. Data were mainly gathered from 4 experienced science teachers through in depth interviews. They were also requested to draw a picture of their visualization of STEM and they were asked explain their drawings, data were then analyzed by categorizing barriers avoiding STEM integration. Three categories were emerged as teacher-oriented barriers, students-oriented barriers and situation...
Science Teachers' Professional Development about Science Centers Enhancing Science Teachers' Views Concerning Nature of Science
Eren-Sisman, Ece N.; Cigdemoglu, Ceyhan; KANLI, UYGAR; KÖSEOĞLU, FİTNAT (Springer Science and Business Media LLC, 2020-10-01)
The purpose of this study is twofold: first, to delve into professional development (PD) of science teachers' views about nature of science (NOS) throughout activities linking NOS aspects to science centers (SCs), and second, to reveal how a science teacher uses NOS aspects while teaching in SCs. An instrumental qualitative case study method with different data sources was used. There were 18 elementary science teachers participating voluntarily in this study. Additionally, one science teacher among the par...
Exploring the use of open educational resources in chemistry laboratory course context: a case study
Tısoğlu, Seçil; Çağıltay, Kürşat; Kurşun, Engin; Department of Computer Education and Instructional Technology (2017)
The first purpose of this study is to provide a detailed perspective for the use and integration of Open Educational Resources (OER) into chemistry laboratory courses through the students’, faculty members’ and teaching assistants’ perspective. Specifically, the factors affected the use and integration of OERs into general laboratory course context through systemic perspective was explained in detailed. The second purpose of this study is to present the impact of these resources on users’ perceived performa...
Exploration of the relations between the teacher‘s discursive roles and the students‘ cognitive contributions to the classroom discourse /
Soysal, Yılmaz; Yılmaz Tüzün, Özgül; Günel, Murat; Department of Elementary Education (2017)
The current study aimed at exploring the relations between the types of teacher discursive roles and the students‘ cognitive contributions to the classroom discourse. Students‘ cognitive operations were considered as their utterances‘ semantic complexity, cognitive pathways, reasoning quality and argument structure. It was also aimed at investigating some contextual influences of the inquiry classrooms on the students‘ ability to make cognitive contributions to the classroom discourse. The participants were...
