Background and Objectives: Angle is a multi-dimensional concept, with different aspects becoming prominent depending on the context. Teachers require a comprehensive understanding of it to teach effectively. Methods: This study examines the knowledge levels of teachers and student-teachers regarding the concept of angle and the sources shaping their experience. Using a mixed-methods approach, the first research question was addressed quantitatively, while the second was explored qualitatively. Key interpretations of angle, such as geometric shape, rotation, intersection, corner, area, distance, slope, and bend, were identified from the literature.
Participants included 132 teachers and student-teachers from Tehran (83 teachers, 49 student-teachers), selected via available sampling. They were asked to provide definitions of angles. Definitions from elementary math textbooks, teacher guides, and Farhangian University resources were also analyzed by experts. Findings revealed that interpretations like "intersection," "geometric shape," "rotation," and "corner" received the most attention, while others were overlooked. Teachers and student-teachers lacked a holistic view of the concept, and learning resources inadequately addressed definitions like geometric shape, corner, area, and intersection, contributing to limited understanding. Given the significant influence of textbooks and teacher training programs, it is suggested that their scope and content be revised to enhance teachers' knowledge and professional competence.
