أثر انموذج بوسنر في تحصيل مادة الرياضيات لدى طلاب الصف الثاني المتوسط
...Show More Authors

     يهدف البحث الحالي الى معرفة أثر انموذج بوسنرفي تحصيل مادة الرياضيات لدى طلاب الصف الثاني المتوسط .

ولتحقيق هدف البحث صاغت الباحثة الفرضية الآتية :

      لا يوجد فرق ذو دلالة إحصائية عند مستوى (0,05) بين متوسط درجات طلاب المجموعة التجريبية الذين درسوا مادة الرياضيات  وفق انموذج بوسنر، وبين متوسط درجات طلاب المجموعة الضابطة الذين درسوا المادة نفسها بالطريقة الاعتيادية في اختبار التحصيل .

      واختارت الباحثة متوسطة الفتوة للبنين لتكون مجتمعاً للبحث الحالي .  واختارت بطريقة عشوائية شعبة (أ) لتمثل المجموعة التجريبية التي سيدرس طلابها مادة الرياضيات وفق انموذج بوسنر ، و شعبة ( ب ) لتمثل المجموعة الضابطة التي سيدرس طلابها المادة نفسها بالطريقة الاعتيادية .

     بلغت عينة البحث (81) طالباً وبواقع (41) طالباً للمجموعة التجريبية ، و (40) طالباً للمجموعة الضابطة .

     كافأت الباحثة مجموعتي البحث بالمتغيرات الآتية (العمر الزمني محسوب بالأشهر ، الذكاء ،التحصيل السابق ) .

      درست الباحثة بنفسها طلاب مجموعتي البحث خلال مدة التجربة التي استمرت (12) أسبوعاً ، واستعمل أداة موحدة لقياس التحصيل لدى طلاب مجموعتي البحث ، إذ أعدت اختباراً تحصيلياً مؤلفاً من (30) فقرة أختبارية من نوع الاختيار من متعدد وبأربعة بدائل ، وتحققت من صدقه وثباته وكذلك إجراء التحليلات الإحصائية لفقراته  ( معامل الصعوبة ، القوة التمييزية ، فعالية البدائل الخاطئة ) .

      واعتمدت الباحثة الوسائل الإحصائية الآتية : الاختبار التائي لعينتين مستقلتين ، ومعادلة معامل الصعوبة ، ومعادلة قوة التمييز ، ومعادلة فعالية البدائل الخاطئة ، ومعامل ارتباط بيرسون .

Experimental and Analytical Study of Bending Stresses and Deflections in Curved Beam Made of Laminated Composite Material
...Show More Authors

Abstract

 

Theoretical and experimental methodologies were assessed to test curved beam made of layered   composite material. The maximum stress and maximum deflection were computed for each layer and the effect of radius of curvature and curve shape on them. Because of the increase of the use of composite materials in aircraft structures and the renewed interest in these types of problems, the presented theoretical assessment was made using three different approaches: curved beam theory and an approximate 2D strength of material equations and finite element method (FEM) analysis by ANSYS 14.5 program for twelve cases of multi-layered cylindrical shell panel differs in fibe

Effect of Solid Loading on Carbon Dioxide Absorption in Bubble Column
...Show More Authors

In the present work experiments were conducted to study  the effect of solid loading (1,5 and 9 vol.%) on the enhancement of carbon dioxide absorption in bubble column at various volumetric gas flow rate (0.75, 1 and 1.5 m3/h) and absorbent concentration (caustic soda)( 0.1,0.5 and 1 M  ). Activated carbon and alumina oxide (Al2O3) are used as solid particles. The Danckwerts method was used to calculate interfacial area and individual mass transfer coefficients during absorption of carbon dioxide in a bubble column. The results show that the absorption rate was increased with increasing volumetric gas flow rate, caustic soda concentration and solid loading. Mass transfer coefficient and interfac

About The Run Length Properties for ( Cumulative Sum(Cusum) and The Exponentially Weighted Moving Average (EWMA)) control charts for Poisson Distribution
...Show More Authors

     In this study, we investigate about the run length properties of cumulative sum (Cusum) and The exponentially weighted moving average (EWMA) control charts, to detect positive shifts in the mean of the process for the poisson distribution with unknown mean. We used markov chain approach to compute the average and the standard deviation for run length for Cusum and EWMA control charts, when the variable under control follows poisson distribution. Also, we used the Cusum and the EWMA control charts for monitoring a process mean when the observations (products are selected from Al_Mamun Factory ) are identically and independently distributed (iid) from poisson distribution i
