Some students could not learn organic chemistry because of the difficulty of its submicroscopic nature. In this study, it was aimed to determine the effect of argumentation-based organic chemistry teaching on high school students' argument construction skills so on their meaningful concept learning. The study was conducted on 14 high school students at a vocational high school in Turkey on organic chemistry topics through 28 hours period based on the case study. The teaching guide's worksheets and students' observation notes were used as data collection tools. Through the application process, the students criticized each of the seven submicroscopic nature of organic chemistry concepts' paintings in big group discussions, then constructed their own arguments. Then the students evaluated the whole process. Content analysis was employed for the data analysis. Argumentation making students criticize the submicroscopic nature of organic chemistry resulted in a qualified student-constructed argument by making them understand the submicroscopic nature so become critical thinkers. Students' process evaluation also underlined that the process made students joyful, motivated, creative, criticizer, and meaningful learners with a differently constructed learning environment. For further studies, different argumentation-based organic chemistry teaching environments could be offered.

Determining pre-service teachers' images and removing their misconceptions with scientifically true ones are very important so that these teachers could bring up students without misconceptions. In the current study, it was aimed to highlight pre-service science teachers' images and misconceptions about chemical equilibrium together and in detail. For this purpose, qualitative research was employed. The research was conducted on 20 pre-service science teachers educating at a university in middle Anatolia region. Worksheets were utilized as data collecting tools. In worksheets there was a question about making pre-service teachers draw four different scenarios for a given chemical equilibrium reaction at different times; at the beginning of the reaction, before the chemical equilibrium, at the chemical equilibrium, after the chemical equilibrium, but at a common temperature and then making them explain their drawings. Data was analysed through content analysis. The results lightened that pre-service science teachers' chemical equilibrium concept images were inadequate since their mental images about the concept were scientifically wrong. On the other hand, the preservice science teachers had different misconceptions. The most common misconceptions of preservice science teachers were as "Diatomic molecules form atoms and then these atoms form new chemicals (f:10).", "There are only products or activated complexes in the tank during and/or afterwards of the chemical equilibrium (f:15).", "Atoms could disappear and/or reappear (f:14).", and "Products are formed at the chemical equilibrium (f:17)."

Biomimicric implementations provide positive contributions to the development of many abilities such as problem solving, creative thinking and productivity by enabling students to look at nature from a different perspective. For this reason, in this study, it was investigated how the biomimicric applications of the macro, micro, and sub-micro nature of freshwater creatures were reflected in their arguments with special gifted students. The research was planned as a summer workshop in an institution that teaches with special gifted students in Ankara in the 2017-2018 academic year, and was carried out on the basis of case study from qualitative research patterns with eight gifted students. In a two-stage study, gifted students conducted microscopic and literature research on freshwater creatures in the first stage and made drawings about the macro, micro, and sub-micro nature of living things. In the second phase, they discussed their biomimicric prototypes in groups and explained them with their arguments. In the study based on document analysis, the data were obtained from students' worksheets and analyzed by content analysis. As a result of the research, it can be said that the concept images of gifted students develop with macro, micro, and sub-micro drawings and the quality of the arguments they construct has become more qualified during the process, and the application contributes to their creative and analytical thinking.

2e (twice-exceptional) students are gifted and differently-abled, so they need specific learning domains according to their needs. This research aimed to design science learning domains for a 2e (gifted and blind) student to enhance his critical thinking in his special learning needs in Ankara province in Turkey in the 2020-2021 academic year's first term. Single-subject research was employed. The 2e student was ten years old. Through the application process, the 2e student argued 3D modeled Schrödinger's cat thought experiment. The main application's intervention was conducted to provide the research's internal validity since it was single-subject research. Through the intervention application, the 2e student argued 3D modeled Schrödinger's twin cats thought experiment. We noted both social dialectic argumentation processes as texts, and these texts were used as data collecting tools. Descriptive analysis was utilized to gathered data. The study showed that the 2e student could construct arguments containing claim, data, warrant, and weak rebuttals in the main application, which meant his argumentation quality level was average, so his critical thinking too. In contrast, the 2e student-constructed arguments containing claim, data, weak rebuttal, and rebuttal meant his argumentation quality level enhanced his critical thinking.

The purpose of this study was to uncover pre-service science teachers' images and misconceptions regarding atomic orbital and self-ionization concepts. This study involved a total of 68 pre-service science teachers working at a public university during the 2015-2016 academic year. In this qualitative study, data were collated with the use of worksheets that participating teachers completed by drawing and explain the concepts regarding atomic orbital and self-ionization concepts. Collated data were then subject to content analysis. The results of this study showed that participants' images about atomic orbital and self-ionization concepts were insufficient and that pre-service science teachers hold various misconceptions about orbital and self-ionization concepts. The reasons of the misconceptions could be backed by the pre-service science teachers' inadequacy regarding the mental construction of proper images of scientific concepts and as a recommendation of the study applications are required for improving pre-service science teachers' scientific concepts images being aware of their inadequacy.

The purpose of the current research was to highlight the STEM motivation and entrepreneurship skills of preservice teachers educating on different programs. For this purpose, the quantitative research approach was conducted, and a survey model was employed. The sample of this research comprised 285 pre-service teachers enrolled in the various departments of faculty of education in a state university in Türkiye. "Entrepreneurship Scale for Teacher Candidates" and "STEM Motivation Scale" were utilized as data collection tools. It was found statistically significant differences between early childhood education and elementary mathematics education, between elementary education and elementary mathematics education, and also between science and elementary mathematics education in favour of elementary mathematics education regarding the mean scores of pre-service teachers' mathematical motivation (MM) in the significance level of .05. It was also found that there was a significant difference between elementary education and elementary mathematics education in favour of elementary education regarding the mean scores of pre-service teachers' self-confidence (SC) in the significance level of .05 in Entrepreneurship Scale for Pre-service Teachers. Also, it was found that there was a significant difference between elementary education and elementary mathematics education in favour of elementary education regarding the mean scores of students' emotional intelligence (EI) in the significance level of .05 on the Entrepreneurship Scale for Teacher Candidates. According to the results, further implementation suggestions were given. [ABSTRACT FROM AUTHOR]
