Study of vestibular stability and formation of graphic writing skills in primary school children
The article presents the results of a study of vestibular stability and the formation of graphic writing skills in 105 children (55 girls and 50 boys) in grades 2-3. Vestibular stability (static-kinetic stability, SKS) was evaluated based on the analysis of the results of the rotation test with the establishment of low, medium and high levels. The assessment of the formation of graphic writing skills (quality of writing) was carried out on the basis of the developed methodology for studying handwriting in primary school children. It was found that a low level of vestibular stability was observed in 73.3 % of girls and 78.6 % of boys in grades 2 (p > 0.05); in 68.0 % of girls and 91.0 % of boys in grades 3 (p < 0.05). Average and high levels of resistance in boys compared to girls were determined, respectively, 2.7 and 4.4 times less often. It is shown that the quality of writing is rated “excellent” and “good” in 65.0 % of children in grades 2 and 69.6 % of children in grades 3. At the same time, girls were more likely to show the quality of writing on “excellent” and “good”. To a greater extent, this difference is typical for students in grades 3, respectively, 80.0 % and 60 % (p < 0.05), compared with students in grades 2-67.0 % and 62.0 % (p > 0.05). Unsatisfactory and poor assessment of the quality of writing was found in girls only in grades 2 (10.0 %), in grades 3 there were no such ratings. The number of boys with unsatisfactory and poor writing scores was 14.3 % (13.8 % in grades 2 and 14.8 % in grades 3). The average score of graphic writing skill formation in children with a low level of SKS was 3.73 ± 0.17 points, with a high level of SKS -4.33 ± 0.20 points (p < 0.05). The results of the study substantiate the need to develop technologies for the development of SCS in children in the course of educational activities to prevent learning difficulties and, as a result, preserve and strengthen their health.
