Abstract

This study aimed to identify the percent of Outlier values in TIMSS international tests (TIMSS, 2011) and the impact of the method of treatment in the students' scores at TIMSS test in accuracy of the estimation Items Parameters according to item response theory according used three–parameter logistic model, The sample consists of (531) students', and pointed out the Outlier values by the Box-plot method, it used the trimmed mean in replacing the Outlier values, and it used the standard error for accuracy of estimating, which showed there are Outlier value at Maths data percent of %6.40, Outlier values in Science percent of %8.29, The results showed that substantial differences between the means of standard errors for the Items parameters estimates, the method of deleting the Outlier values has a positive effect comparing with the method of (replacing and keeping) Outlier values, and it is adviced that it is the best and the most successful method of Treatment with the Outlier values in TIMSS 2011 in Maths on the mean estimated Items parameters (discrimination and guessing) and its accuracy, and in Science on the mean estimated discrimination parameter and its accuracy. As the results showed that the method of keeping Outlier values has a positive effect comparing with the method of (replacing and deleting), it is advised that it is the best and the most successful method of keeping with the Outlier values in TIMSS at Science on the mean estimated Items parameters (guessing and difficulties) and its accuracy, at Maths on the mean estimated difficulties parameter and its accuracy.

الملخص

هدفت هذه الدراسة إلى تحديد نسبة القيم المتطرفة في اختبارات تيمس الدولية (TIMSS, 2011)، والكشف عن أثر معالجة القيم المتطرفة في مادتي العلوم والرياضيات على تقديرات المعالم للفقرات ودقتها وفقًا للنموذج اللوجستي الثلاثي المعلمة، وتكونت العينة من (531) فرد، وتم تحديد القيم المتطرفة بطريقة الرسم الصندوقي ومعالجتها بطريقة متوسط البتر، وتم الحكم على دقة تقدير المعالم باستخدام الخطأ المعياري كمؤشر دقة، حيث أظهرت النتائج قيم متطرفة في اختبار مادة الرياضيات بما نسبته (6.40%)، وفي مادة العلوم بما نسبته (8.29%)، وأظهرت النتائج أنَّ هناك فروق جوهرية بين الأوساط الحسابية للأخطاء المعيارية لتقديرات معالم الفقرات، وأنَّ أسلوب حذف القيم المتطرفة له أثر إيجابي بالمقارنة مع أسلوبي: الاستبدال والاحتفاظ، وينصح به كأفضل الأساليب بمعالجة القيم المتطرفة في اختبارات تيمس الدولية 2011)) في مادة الرياضيات على الوسط الحسابي لتقديرات معالم الفقرات: التمييز والتخمين ودقتها، وفي العلوم على الوسط الحسابي لتقديرات معلمة التمييز ودقتها، كما أظهرت النتائج أنَّ أسلوب الاحتفاظ بالقيم المتطرفة له أثر إيجابي بالمقارنة مع أسلوبي: الاستبدال والحذف، وينصح به كأفضل وأنجح الأساليب بمعالجة القيم المتطرفة في اختبارات تيمس الدولية (2011) في العلوم على الوسط الحسابي لتقديرات معالم الفقرات: التخمين، والصعوبة ودقتها، وفي الرياضيات على الوسط الحسابي لتقديرات معلمة الصعوبة ودقتها.
