Abstract

The present study aimed at identifying the effect of the length of the questionnaire on the Accuracy of Ability Estimation of the parameters of examinees and The parameters of Items and scale in the light of IRT, the sample of the study was selected in a available sample by distributing the questionnaire samples to the teachers. Amounted (1425) male and female teachers, were (1038) male and (387) female distributed to (492) teachers of the questionnaire (10 items) And (497) teachers of the questionnaire (30 items) and (436) teachers of the questionnaire model (60 items), in order to achieve the objectives of the study; Abdel-Jawad & Metwally (1993) questionnaire job satisfaction of teachers was used, The results showed statistically significant differences at the level of (α = 0.05) between the standard error average in the estimation of the abilities of individual related to the length of the questionnaire; the results showed differences between the standard error averages in favor Length of questionnaire (60) compared to (length of questionnaire (10) and (30)), then for (30) compared to the length of the questionnaire (10). The findings also indicate that there were statistically significant differences at the level of significance (α = 0.05) between the averages of the standard error in estimating the discrimination parameter for the item related to the length of the questionnaire; a differences between the average of the standard error in favor for the length (30) compared to the length of the questionnaire (10), and in favor of the length of the questionnaire (60) compared to the length of the questionnaire (10). Lastly the results indicate there were no statistically significant differences between the averages of the standard error in estimating the difficulty parameter of the item due to the difficulty parameter and length of the questionnaire, and to the interaction of the difficulty parameter with the length of the questionnaire, and to the interaction of the difficulty parameter with the length of the questionnaire, in the light of the results of study the researcher recommended questionnaire developers as a tool for their research taking into account the length of the item to achieve accuracy in the speed estimates of the sample elements. It is better to be from the same paragraph (30) or more.

الملخص

هدفت الدراسة للتعرف إلى أثر طول الاستبانة على دقة تقدير معالم القدرة للأفراد, ومعالم الفقرات والمقياس وفق نموذج الاستجابة المتدرجة (GRM). فتم اختيار عينة الدراسة بالطريقة المُتيسرة؛ وذلك بتوزيع نماذج الاستبانة على المعلمين، حيث بلغ عدد أفراد العينة (1425) معلمًا ومعلمة، منهم (1038) معلمًا و(387) معلمة؛ موزعين إلى (492) معلمًا ومعلمة لنموذج الاستبانة (10 فقرات) و(497) معلمًا ومعلمة لنموذج الاستبانة (30 فقرة) و(436) معلمًا ومعلمة لنموذج الاستبانة (60 فقرة)، كما تم استخدام استبانة للرضى الوظيفي ، وأظهرت النتائج وجود فروق دالة إحصائيًا عند مستوى الدلالة (α=0.05) بين الأوساط الحسابية للأخطاء المعيارية في تقدير قدرات الأفراد يُعزى لطول الاستبانة؛ وأنَّ الفروق الجوهرية بين الأوساط الحسابية للأخطاء المعيارية وفقاً لطول الاستبانة كانت على الترتيب: لصالح طول الاستبانة (60) مقارنةً بطول الاستبانة (10) ثم (30)، ولصالح طول الاستبانة (30) مقارنةً بطول الاستبانة (10). وأظهرت النتائج أيضا وجود فروق دالة إحصائيًا بين الأوساط الحسابية للأخطاء المعيارية في تقدير معالم التمييز للفقرات يُعزى لطول الاستبانة؛ وأنَّ الفروق الجوهرية بين الأوساط الحسابية للأخطاء المعيارية كانت لصالح طول الاستبانة (30) مقارنةً بطول الاستبانة (10)، ثم لصالح طول الاستبانة (60) مقارنةً بطول الاستبانة (10). وأظهرت النتائج عدم وجود فروق دالة إحصائيًا بين الأوساط الحسابية للأخطاء المعيارية في تقدير معالم صعوبة الفقرات يُعزى لمعالم عتبة الصعوبة وطول الاستبانة، والتفاعل بينهما، وفي ضوء نتائج الدراسة يوصي الباحثان على مطوري الاستبانات كأداة لبحوثهم مراعاة طول الاستبانة للحصول على دقة في تقديرات القدرة للأفراد عينة الدراسة. والأفضل أن تكون من ذات (30) فقرة فأكثر.
