AB - This study analyzed observation-based feedback documents from pre-service informatics teachers' teaching demonstrations using grounded theory coding procedures, identifying 5 major categories and 23 subcategories of instructional difficulties. Teacher–student interaction and lesson content organization showed the highest frequencies. Co-occurrence analysis revealed that these difficulties form an interconnected structure rather than isolated deficits across specific domains. Informatics-specific difficulties - particularly insufficient concretization of AI and algorithm concepts and inappropriate use of examples for unsupervised learning - were found to reflect an absence of subject-specific PCK. The findings provide implications for strengthening subject-specific PCK competencies in pre-service informatics teacher education programs.
