The purpose of this study is to explore the assessment of emotions and social skills of sixth-year primary education students in a physical education (PE) teaching unit. Two instruments of analysis are used: the GES (Games and Emotion Scale) to evaluate emotions, and an ad-hoc questionnaire to measure the social skills of 21 students in their sixth year of primary education. The data analysis was carried out using a generalised estimating equation model (GEE), taking into account the correlation between the different scores of the same subject and the asymmetry of the data. The results show that positive emotions (happiness and joy) are significantly more highly evaluated than negative (fear, anger, and sadness) and ambiguous (surprise) emotions throughout all of the PE sessions
