This study quantitatively analyzes the curriculum structure of mathematics education departments in Korean colleges of education and examines how these institutional arrangements relate to in-service mathematics teachers' practical needs, based on curriculum data and teacher perceptions.The curriculum analysis indicates a clear disciplinary content-oriented sequence: mathematics content courses account for 68.9% of total credits and are arranged from the early years, whereas mathematics education courses become more prominent in the later years.Notably, a discrepancy was found between nominal course titles and their actual functions, as several courses categorized as pedagogy-oriented incorporate substantial content components, making it difficult to infer their instructional function from titles alone.Survey results identify major barriers in classroom practice, including limited understanding of teaching and learning methods, assessment methods and components, and curriculum interpretation.Specific qualitative accounts from the open-ended responses further suggest that these challenges are not merely a lack of isolated skills but stem from the complex nature of professional practice, which requires the organic integration of various elements.These elements include calibrating instructional goals and difficulty levels across wide ranges of student ability levels, designing performance assessments while ensuring fairness, translating standards into justifiable classroom decisions, and articulating the value of mathematics to students.Overall, the findings suggest that increasing disciplinary content alone does not guarantee teacher professional competence; teacher education curricula should be qualitatively restructured to provide repeated and scaffolded opportunities across all academic years for transforming disciplinary knowledge into classroom design, assessment, and decisions responsive to learners.
