    A Q Methodological investigation of students' perspectives on power plants
    (Mehmet Tekerek, 2024) Guduk, Sadik Taner; Es, Huseyin; Turkoglu, Ayse Yenilmez
    The aim of this research, which was conducted through the use of Q methodology, was to examine eighth grade students' perspectives on power plants (PPs). Suggesting that variables can be replaced by individuals in factor analysis and thus interpersonal factor analysis can be done, Q methodology is a method that aims to examine individuals' self -referenced perspectives by revealing the differences and commonalities of these perspectives; that is, where they are positioned relative to each other in a holistic structure. In this research, a total of 35 Q -statements were presented to a number of 19 eight -grade students, who were attending to a public middle school and were voluntarily participated in the study. Students' Q -sorts resulted in a two -factor solution, meaning that two perspectives emerged towards PPs. The perspectives were named as economy -oriented and science and technology -oriented. Students holding the economy -oriented perspective pointed out to the positive impact of PPs on economy, while others holding the science and technology -oriented perspective specified the contribution of PPs to scientific and technological development.

    Science teacher candidates' perceptions about roles and nature of scientific models
    (Routledge Journals, Taylor & Francis Ltd, 2016) Turkoglu, Ayse Yenilmez; Oztekin, Ceren
    Background: Scientific models have important roles in science and science education. For scientists, they provide a means for generating new knowledge or function as an accessible summary of scientific studies. In science education, on the other hand, they are accessible representations of abstract concepts, and are also organizational frameworks to teach and learn inaccessible facts. As being indispensable parts of learning and doing science, use of scientific models in science classes should be reinforced. At this point, uncovering pre-service science teachers' (PSTs) understandings of scientific models are of great importance since they will design and conduct teaching situations for their students. Purpose: The study aimed to provide an answer to the research question: What understandings do PSTs possess about scientific models? Sample: The sample of the study consisted of 14 PSTs enrolled in an Elementary Science Education program in a public university in Ankara, Turkey. Design and methods: Data were collected by using an open-item instrument and semi-structured interviews, and were analyzed by using qualitative data analysis methods. Results: Findings showed that PSTs held fragmented views of models by having informed views in some aspects while having naive views on others. That is, although they displayed a constructivist orientation by acknowledging the presence of multiple models for the same phenomenon depending on scientists' perspectives or creativity involved in the production of scientific knowledge, PSTs also expressed logical positivist views by believing that models should be close to the real phenomena that they represent. Findings further revealed that PSTs generally conceptualized models' materialistic uses, yet they did not think much about their theoretical and conceptual uses. It was observed that roles like reifying and visualizing were overestimated and models were dominantly characterized as three-dimensional representations. Conclusions: It is clear that PSTs, having difficulties in grasping the concept of models, would possibly have problems in planning their lessons effectively and would not develop accurate concepts in their students. These findings apparently support the need for appropriate pedagogic training of PSTs to scientifically reflect on and professionally make use of models in science classes.

    Science teacher's perceptions of the nature of technology: a Q-methodology study
    (Springer, 2022) Turkoglu, Ayse Yenilmez; Aydin, Fatih; Es, Huseyin
    The aim of the current study was to explore science teachers' perceptions of the nature of technology through the use of Q methodology. 17 science teachers were sampled as participants, and to explore their perceptions of the nature of technology, they ranked a Q-sort of 36 statements that constituted the following six categories: (i) definition of technology, (ii) the relationship between science and technology, (iii) the impact of society on technology, (iv) the impact of technology on society, (v) the impact of technology on environment, and (vi) the impact of technology on economy. As the participants completed their Q-sort, they were interviewed. Analysis of the participants' Q-sorts resulted in a three-factor solution, i.e. three distinct patterns of perception about the nature of technology. The three perspectives included teachers who are (i) equally aware of the benefits and drawbacks of technology and the relation of it to science, (ii) optimist about technology and aware of its dependence on society, and (iii) optimist about technological innovations but tempered by technology-driven environmental and social issues. Findings indicated gender and years of professional experience as potential determiners within these perspectives, which needs further research.

    Socio-scientific issues as a context for STEM education: A case study research with pre-service science teachers
    (Eurasian Society of Educational Research, 2018) Altan, Esra Bozkurt; Ozturk, Nurhan; Turkoglu, Ayse Yenilmez
    This study was designed as a case study. Participants were 12 senior pre-service science teachers (PSTs), who took theoretical and practical courses about STEM education and socio-scientific issues (SSIs) during their education at a state university. For the study, in the first 4 weeks, theoretical courses on SSIs and STEM education were carried out. Afterwards, PSTs were asked to choose a SSI and configure this issue as a problem statement to perform a STEM activity. Participants were given a total of 3 weeks to determine the issue and prepare the STEM activity, and the researchers of the study gave systematic feedback during this period. Then, starting from the fifth week of the study, groups started to implement their STEM activities in the class, where their peers were assigned as their students. The activity plans they prepare, the field notes taken by the researchers during the implementation of the activities and the semi-structured interviews about the opinions of the PSTs on the use of SSI in STEM education were the data sources of the study. Findings revealed that PSTs found establishing STEM problem situations over SSIs suitable since they provide features such as conformity to real life, having multiple criteria and providing compatibility with other disciplines. Moreover, after their practices, they pointed out that the activities enabled both the teaching of the SSI and the integrated teaching to be carried out. As a conclusion, it is recommended to use socio-scientific problem situations to perform STEM education. © 2018 Eurasian Society of Educational Research. All rights reserved.
