Analyzing Turkey's, Chine's and Singapore's science curriculum regarding the context of pedagogical content knowledge

The aim of this study is PISA, an assessment tool that covers knowledge and guides, and the science curriculum of our country, which is below the average according to the analyzed reports of China (Hong Kong) and Singapore, which are in the first place according to the data on science, mathematics and reading. is to evaluate it according to the pedagogical content knowledge components. It is to reveal the similarities and differences between the countries included in the research. In the study, science curricula of China (Hong Kong), Singapore and Turkey were discussed. The sub-components of the Magnusson (1999) model were included in the study. The inclusion of the countries in the study is to make an evaluation according to the pedagogical content knowledge's components according to the PISA reports and to bring them into the literature. In the study, document analysis, the research model of which is a qualitative research method, was used because it was aimed to reveal the pedagogical content components of the countries included in the study. In order to reach the documents in the study, it was obtained from the web environment of Education Bureau, National Curriculum Information Center-NCIC and Board of Education. For the analysis of the study, the curricula of the countries included in the research were selected as a sample. At the same time, sub-components in the Magnusson (1999) PCK model are included in order to develop the categories. The validity and reliability of the study; credibility, transferability, consistency and confirmability parts are included. As a result of the study, it was seen that there were differences between the countries included in the study, especially among the pedagogical content components of our country. While it is similar to Singapore in science teaching harmony, it has been revealed that there are differences with Hong Kong in its pedagogical sub-components. Although there are many differences between Singapore and Hong Kong in general, they rank high in international exams.
