The sample for this study was 922 students, of both genres and in 40 Compulsory Secondary Education, aged between 14 and 18 years. To carry 41 out the study, the Student's Scale of Responsibility was used in the physical 42 education assessment, the Basic Psychological Needs Measuring Scale, the 43 Percentage Scale for Physical Education Causality and the Satisfaction Scale 44 in Physical Education. The results of the structural equations model revealed 45 a good adjustment to the data. This finding highlights the importance of giving 46 responsibilities to the students in the evaluation process, in order to satisfy the 47 psychological needs of the students and, therefore, self-determined 48 motivation, thus increasing satisfaction towards physical education classes. 56 authors [6, 7] who indicate that, traditionally, teaching has consisted in a 57 pedagogical model of direct instruction.
58Research has determined that the teacher's use of strategies, with 59 positive psychological aspects, such as the increase of students' intrinsic 60 motivation in PE classes, will allow for the development and consolidation of 61 behaviours related to physical activity [8, 9, 10].
62Motivational phenomena combining a set of biological, emotional, 63 cognitive and social aspects, which at the same time are interrelated with 64 each other, influence persistence, intensity and frequency of behaviour, and 65 interact with each other by increasing, maintaining or decreasing this 66 behaviour [11].
67One of the theories that helps to explain the motivation of students in 68 PE classes is called the Self-determination Theory (SDT) [12, 13]. The SDT, 69 proposes that motivation is framed throughout a three-level continuum [14,70 15]: autonomous motivation (the most self-determined, required for an activity 71 to be carried out for sheer pleasure), controlled motivation (carrying out an 72 activity for reward or recognition outside of the activity) and demotivation (the 73 least self-determined) [16].
74Furthermore, it establishes three Basic Psychological Needs (BPN):75 autonomy (the desire to engage in activities by one's own choice), 76 competence (the desire to interact efficiently with the means to feel 77 competent) and relatedness (the desire to feel part of a group) [16, 12].
78According to the SDT, the BPN constitute the psychological mediators 79 that influence the three main types of motivation [12, 17]. Several studies...
