[Professors' perception of students' feelings in the classroom: an analysis].

The objective of this study is to verify the difference in professors' perception of students' feelings before and after an explanatory presentation on the theme. This is an exploratory study using a primary source, and a quantitative approach with 13 Nursing and Medicine professors. A vide showing student images was presented to the professors, who answered a feeling-identification questionnaire, and, after an explanatory presentation about non-verbal communication and feelings, the professors watched the same video and answered the questionnaire again. As to the identification of feelings, joy, anxiety, and interest were the most often identified. We found statistically significant values regarding the mean total score before and after the explanatory presentation (p=0.02). The professor is capable of identifying the feelings, but after the explanatory presentation, their perception improved and they were able to make identifications more often.
