Teaching the Sound Concept: A Review of Science and Physics Education Postgraduate Theses in Turkey

The purpose of this study is to review the postgraduate theses on science/physics education in Turkey to guide the teaching of the sound concept. Although the theses examined within the scope of this study belong to a certain region, the previous literature shows us that the learning difficulties/misconceptions are generally independent of culture. Thirty-three theses in the database of The Council of Higher Education Thesis Center were analyzed inductively in the semi-systematic review process. For this, the stages of content analyses were used: Elimination and coding, placing them in themes, ensuring reliability and validity were followed respectively. Unit of analyses was conclusions of the theses and suggestions of the theses. In conclusion, both conventional and contemporary approaches have a positive effect on achievement or conceptual change on the sound concept. On the other hand, students and teachers/ candidates, in general, cannot relate their knowledge of sound to daily life, their level of knowledge is inadequate, and they have misconceptions/errors and confusions. It is beneficial to consider this situation in education. The most important output of this study is the lists of possible misconceptions or confusion about the concept of sound. Teachers and researchers can use these lists in their lessons or research. Keywords: education, physics, science, sound, thesis
