Design And Application Of "Preschool Children’s Self-rating Scale Of Activity Intensity"

Objective:This research focuses on the social environment in the kindergarten sports activities, to design a preschool children’s self-rating scale of activity intensity (PSAI) by experiments. Children could use this scale to evaluation their own current activity intensity, provide a reference for kindergarten teachers to master the intensity level of daily physical activity. Teachers can use this as a basis for a more scientific and reasonable arrangements for time and frequency of sports activities, scientific and effective guidance of children activities.Methodology:Children’s activities abroad prior reference intensity rating scale and research teams from preliminary studies preliminary assessment scale he designed PSAI. Choose 153 top class children from a Beijing municipal model kindergarten to identify the scale, while quantitative stress test, and then modify the scale based on the results. Then using the modified scale, choose another 116 top class children quantitatively increasing load experiments,Results:1. Children’s understanding of PSAI well, most children can understand the meaning of the scale, and the ability to select the current status of activities in line with its own rating scale according to their own circumstances.2.The PSAI each grade and objective indicators correlated well (r> 0.6); scale heart rate range for each grade has a significant difference.3. The PSAI test-retest reliability is good, the requirements established to achieve scale; at the same time good test results validity scales, and the entry rational design, let the children choose the self-rating scale at each intensity level. Finally, select the 138 children in kindergarten were reliability and validity testing.Conclusion:1.This study has been developed the PSAI.2. The PSAI is a self-rating scale of six options. The scale level and the heart has a good correlation, the correlation coefficient r> 0.6. Scale Level 1 represents a low-intensity activity, Level 2and3 represents a moderate-intensity activity, Level 4and5 represents a vigorous-intensity activity, Level 6 represents a high-intensity activities.3. The PSAI has a good test-retest reliability, test-retest correlation coefficient r> 0.8; and validity test result is good.4. The PSAI applies to nursery activities of daily physical activity intensity, understanding the extent of 5 to 6 years old Preschool ideal for this scale, it is possible to distinguish the levels of meaning of the scale, and the ability to reference it elected its current activity rate comparable rank.
