Playfulness, a trait previously identified in kindergarten and high school pupils and found related to divergent thinking, was investigated in an exploratory study as a possible teacher characteristic. Sixteen teachers completed an open-ended questionnaire aimed at defining playfulness in teachers. A content analysis produced eight component traits: a) sense of humor; b) kindness, sensitivity; c) cheerfulness, laughter; d) enthusiasm, active participation; e) flexibility; f) imagination; g) at ease, or relaxation; and h) entertainment. There were indications that playfulness in the teacher encouraged divergent thinking in the classroom, thus following the inference that this trait in a teacher influences pupil behavior. (Author/BRB)
