Abstract
Greek students (N = 310) responded to surveys concerning their perceptions of the physical education class environment. Based on factor and reliability analyses, 14 scale scores were computed. Two depicted perceptions of teacher-initiated mastery orientation and teacher-initiated performance orientation. Six scale scores reflected the teachers' negative behavior toward boys, focus on boys' learning, encouragement toward boys, autonomy given to boys, adjustment of the lesson for boys, and motivation of boys. Six identical scale scores were calculated assessing the physical education class climate for girls. The perception of a teacher who behaves differently toward boys and girls was negatively related to the perception of a teacher who tried to help all students to improve. It is suggested that a mastery orientation increases students' motivation and maintains equality in physical education.
