Abstract
The purpose of this study was to apply the Personal and Social Responsibility Model (TPSR) and verify its effects on responsibility and motivation according to educational stage. For this, teachers from Physical Education and other subjects were trained and a pre-test and a post-test were carried out. The intervention was carried out over five months. The total sample comprised 408 students after the inclusion criteria were applied to the initial sample of 430, including being 192 students from 5th and 6th grade of Elementary (M 10.16; SD = 0.77) and 222 from Secondary (M = 12.86; SD = 0.70), with a confidence level of 95% and 5% error margin. The total number of students in the experimental group was 216, with 192 in the control group. The results reflected improvements in the experimental group in terms of experience motivation, identified regulation, amotivation, autonomy, competence, social responsibility, SDI, and BPNs (p < 0.05 and d Cohen > 0.2). The control group did not present differences in any variable. Considering the differences according to stage, the Elementary school group obtained values of p < 0.05 and d > 0.02 in experience motivation, amotivation, autonomy, competence, personal and social responsibility, SDI, and BPNs, which was not found in the Secondary school group. It is concluded that the TPSR may be applicable in both Elementary and Secondary schools to improve the motivation and responsibility of students, with the most favorable results for Elementary education students.
