سنجش میزان هماهنگی چشم و دست کودکان با استفاده از ابزار پوردو پگ‌بُرد

تاخیر در رشد شناختی، مهارت‌های حرکتی، مهارت‌های ظریف انگشتان دست و همچنین اختلال در هماهنگی بین چشم و اندام حرکتی کودک تاثیر نامناسبی بر فرایند یادگیری در مقاطع بالاتر سنی دارد و موجب ضعف اعتماد به نفس در کودک می‌گردد. از این رو لازم است تا در طراحی محصولات برای کودکان به میزان هماهنگی چشم و دست با عملیاتی که توسط دست کودک بر روی محصول صورت می‌گیرد توجه کافی شود. هدف از این پژوهش شناخت میزان توانایی کودکان بمنظور ساخت محصولاتی است که هماهنگی چشم و دست در کاربرد آنها ضروری است. این پژوهش از نوع نیمه تجربی بوده و به روش مداخله‌ای انجام شده است. در این پژوهش با استفاده از آزمون پوردو پگ‌بُرد تعداد20 کودک 3 تا 6 سال از یکی از مهدکودک‌های منطقۀ پنج تهران مورد سنجش قرار گرفتند. نتایج نشان داد با افزایش سن، مهارت‌های ظریف انگشتان دست و همچنین میزان هماهنگی چشم و دست کودکان به صورت قابل توجهی بهبود می‌یابد اما 42% از جامعۀ نمونه دارای تاخیر حرکتی و شناختی بودند. همچنین مشاهده شد که دختران در مجموع از سرعت عمل بالاتری برخوردار بودند. برخلاف اینکه انتظار می‌رفت رابطه معناداری بین جنسیت و مهارت حل مساله وجود نداشته باشد، یافته‌ها نشان دادند پسران بیشتر از دختران در فرایند آزمون سعی در ایجاد ساختار جدید و حل مساله داشتند. در واقع، پسران تمایل داشتند قواعد آزمون را بر هم زده و برای انجام آزمون راه حل جدیدی بیابند و همچنین فرایند چیدمان قطعات بر روی صفحه را تغییر دهند. این در حالی است که دختران، با پذیرش قواعد تعیین‌شده، به آزمون ادامه دادند.

assessment of eye-hand coordination in children taking purdue pegboard test

background and objectives: the impairment of cognitive development, motor skills, fine motor skills, and the lack of coordination between the child’s eyes and motor organs can negatively impact the learning process at later ages and result in low self-esteem in children. thus, it is crucial to consider the level of coordination between the child’s eyes and hands when designing products intended for children. the objective of this study is to assess the capability of children in creating products that necessitate eye-hand coordination during their use.methods: the research conducted was a semi-experimental intervention study. the study involved 20 children between the ages of 3 and 6 who attended a kindergarten in the panj district of tehran. the purdue pegboard test was used to evaluate the children’s manual dexterity and two-handed coordination. this test is commonly used to measure movement and cognitive skills in a variety of populations, including children, adults, the elderly, post-surgery patients, and those with special needs. the test evaluates both gross movements of arms, hands, and fingers as well as fine motor skills of the fingers. additionally, the test can also be used to assess cognitive skills. to perform the test, the child was asked to place the pieces on the purdue pegboard with the right hand, left hand, and both hands, within a period of one minute, and five separate points were collected, which include the following is.1. right-hand privilege.2. left-hand score.3. two-handed privilege.4. the sum of the points of the hands, which is the sum of the points of the right hand + left hand + both hands.findings: the findings show that most four-, five- and six-year-old children had higher scores on the right hand than the left hand, which could be due to the influence of the dominant hand on the test process, but three-year-old children scored more on the left hand. also, the findings ‌show that girls scored higher than boys in right hand, left hand, both hands and assembly. most three-year-old children spent more than three seconds in choosing and deciding to place pieces, while this time was significantly reduced in five- and six-year-old children. the findings showed that the eye-hand coordination in children increases with age. most six-year-old children picked up and placed the pieces with two or three fingers, which shows that the child is at an acceptable level in terms of fine finger skills. but three- and four-year-old children were faced with tremors and lack of hand control when removing the parts and placing them, and even some three-year-old children used their other hand to place the parts to prevent tremors and control their hands. contrary to what was expected, there is no significant relationship between gender and problem-solving skills, but the findings showed that boys try to create a new structure more than girls in the test process.conclusion: the research results show that the age variable has an effect on the speed of action and eye-hand coordination as well as the fine dexterity of children’s fingers, and children at older ages have higher and better performance, which is consistent with the results of the study of pehoski et al. (1997), brito and santos-morales (2002) as well as wilson et al. (1981).
