    College students’ plausibility perceptions about global climate change
    (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2023., 2023) Özyazıcı, Gizem.; Ceyhan, Gaye Defne.
    Human-induced climate change is causing an increase in extreme weather events due to its profound effect on the Earth’s atmospheric balance. The main purpose of the current study was to investigate whether college students’ plausibility perceptions on global climate change (GCC) increased after participating in a scaffolding activity. The study sample consisted of 62 students from a private research university in the United States. Three instruments were used to investigate the research questions. First, the demographic information form for the participants’ and Plausibility Perception Measure (PPM) scale were used. PPM scale was implemented before and after the Extreme Weather (EW) Model Evidence Link (MEL) activity. The results showed that students’ plausibility perceptions changed significantly after the MEL activity. Secondly, in the EW MEL activity, students were asked to evaluate two different models and the results showed that more students found Model A (scientific explanation) more plausible than Model B (alternative explanation). However, Model B was also found plausible by many students. Students’ alternative explanations were mostly found to be in the erroneous evaluation category for the EW MEL diagram. The results showed that students were aware that human activities have a major impact on current GCC, but they still have misconceptions about GCC and its link to EW events. This study contributes to the literature by using an updated PPM scale and a current EW MEL diagram, as EW events have increased significantly in recent years. This study also shows that college students have a lack of understanding of GCC and EW events. Critical evaluation is a scientific practice that could be explicitly taught in higher education programs to improve students’ engagement and understanding of evidencebased decision-making practices.

    Gamified-integrated STEM : exploring 8th grade students' problem- solving skill perceptions and critical thinking dispositions about global climate change
    (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2023., 2023) Özdinç, İlkem.; Ceyhan, Gaye Defne.
    Gamified-integrated STEM is one of the techniques that combines integrated STEM stages with gamification elements and can engage individuals in climate change communication (Rajanen & Rajanen, 2019). The main purpose of this study is to investigate gamified-integrated STEM-based instruction on global climate change causes a significant change in 8th-grade students' perceptions of problem-solving skills, critical thinking dispositions, and climate change views. In this quasi- experimental study, the sample consisted of sixty-nine 8th grade students from a public school in Turkey. Three classes of twenty-three participants each were named as the traditional group, experimental group 1 (integrated STEM group), and experimental group 2 (gamifiedintegrated STEM group). The data was collected in the 2022-2023 academic year. Problem-solving skill perceptions scale, critical thinking disposition instrument, and interviews were used to examine the research questions. According to the findings of the study, statistically significant differences were found between the pre & post-test scores of both scales in the lessons taught with gamified-integrated STEM instructional design compared to the other groups. When all groups were compared, the highest difference was found between the gamified-integrated STEM group and the control group. In addition, when taking the students' views on global climate change, it was found that the students in the gamified-integrated STEM group had higher levels of hope about global climate change and a desire to take action. The results revealed that gamified-integrated STEM activities on global climate change could be used, especially in subjects considered difficult to learn. It is expected that the results obtained from this research will create an opportunity for improving global climate change education within the scope of gamifiedintegrated STEM education.
