目的探讨学业不良中学生的精细运动控制特点,为学业不良学生的诊断和干预提供依据。方法从广州某中学初二年级和高二年级分别选取学业不良学生和中等生各20名,采用WACOM-2005-1型数码写字板,进行定点横线和定点竖线的书写。结果学业不良学生书写定点横线的速度为(17.74±19.24)mm/s,显著慢于中等生的(23.03±0.64)mm/s,差异有统计学意义(P<0.05);学业不良学生书写定点竖线的速度变化系数为(0.39±0.16),显著低于中等生的(0.46±0.17),差异有统计学意义(P<0.05)。结论学业不良中学生中可能存在精细运动控制失调的延续,应重视对其进行运动控制的干预。
Objective To explore the characteristics of fine motor control of students with poor academic performance and to provide basis for the diagnosis and intervention of students with poor academic performance. Methods Twenty first-grade students and second-year sophomores were selected from each of the 20 middle schools in Guangzhou. Each of them was written in WACOM-2005-1 digital tablet. Results The rate of writing-in horizontal lines was (17.74 ± 19.24) mm / s, which was significantly slower than that of the middle-school students (23.03 ± 0.64) mm / s, with statistically significant difference (P <0.05) The rate of change of fixed point vertical line was (0.39 ± 0.16), which was significantly lower than that of moderate (0.46 ± 0.17), the difference was statistically significant (P <0.05). Conclusion There may be a continuation of the fine motor control disorder in the middle school students with poor academic performance, and their intervention in exercise control should be emphasized.
