Box 23, Agona Nkwanta 每 Western Region 每 Ghana West Africa The impact of science instructors' Pedagogical Content Knowledge (PCK) on educational practice was studied in this study. Synthesis of a teacher's subject knowledge and pedagogical skill is described as PCK. The study's goal was to see if there was a link between Ghanaian science instructors' PCK and classroom practices. This research employed a descriptive survey approach. Eighty (80) teachers were randomly recruited and data was collected using a standardized questionnaire. Simple percentages and charts were used to organize and illustrate the data. It was revealed that subject matter understanding varies depending on a teacher's level of education. Experienced teachers, on the other hand, demonstrated greater pedagogical expertise and were better able to improve academic achievement than inexperienced teachers. The formal education of a teacher was a strong predictor of their knowledge and ability in the classroom. According to the findings of this study, teachers' pedagogical and subject-matter knowledge are crucial for effective science instruction and student comprehension. http://pubs.sciepub.com/education/10/7/2/education-10-7-2.pdf content integrated science pedagogical knowledge synthesis
