تهدف الدراسة الحالية إلى معرفة أثر استخدام نموذج ويتلي في اكتساب طلاب الصف الثاني الأساسي لمادة قواعد اللغة العربية. وللتحقق من هدف الدراسة فرضت الفرضيات الصفرية الآتية: الفرضية الصفرية الأولى هي (لا توجد فروق ذات دلالة إحصائية عند مستوى (0.05) بين متوسط درجات المجموعة التجريبية التي درست مادة قواعد اللغة العربية وفق نموذج ويتلي ومتوسط درجات المجموعة الضابطة التي درست مادة قواعد اللغة العربية وفق الطريقة الاعتيادية). وقد اختار الباحث مدرسة البلد للبنين والتي تضم قسمين من الصفوف من الثاني المتوسط كعينة لدراسته، حيث تكون القسم (أ0) المجموعة التجريبية، والقسم (ب). وبلغت عينة الدراسة (60) طالباً بواقع (30) طالباً لكل مجموعة. وبعد ذلك قام الباحث بمطابقة المجموعتين إحصائياً باستخدام اختبار (ت) في المتغيرات التالية (العمر، درجات اللغة العربية في الامتحان النهائي للصف الأول، الاختبار اللغوي، باستخدام مربع كاي، وتعليم الوالدين). وبعد تحديد موضوعات المادة العلمية التي ستدرس للعينة في ثمانية موضوعات، قام الباحث باختبار فرضيات الدراسة التالية: أعد الباحث الخطة وعرضها على مجموعة من الخبراء في المجال، ولقياس اكتساب الطلبة للموضوع قام الباحث بإعداد اختبار مكون من (30) فقرة منها (20) فقرة من نوع الاختيار من بين عدة فقرات، و(10) فقرات من نوع إكمال النواقص، وعرضها على الخبراء للتحقق من صدقها، وطبق الاختبار على عينة من الطلبة والطالبات من الصف الثاني الثانوي في مدرسة أبي العلاء المعري الثانوية للبنين، وبعد تحليل بيانات إجابات الطلبة باستخدام الأساليب الإحصائية المناسبة وجد الباحث أن جميع الفقرات صالحة، ولحساب ثبات الاختبار استخدم معادلة كودور-ريتشاردسون. وبعد معالجة البيانات إحصائياً باستخدام اختبار (ت) تبين وجود فرق ذي دلالة إحصائية بين متوسط درجات مجموعتي الدراسة لصالح المجموعة التجريبية التي درست مادة قواعد اللغة العربية وفق نموذج ويتلي، وفي ضوء النتائج يستنتج الباحث أن اتباع نموذج ويتلي في التدريس له دور إيجابي في رفع مستوى التحصيل لدى طلبة كليات التربية، ويوصي الباحث بتدريس طرق تدريس اللغة العربية في كليات التربية باتباع خطوات نموذج ويتلي وتدريب الطلبة على كيفية إعدادها واستخدامها، ويقترح إجراء دراسة مماثلة تتناول أسباب استخدام نموذج ويتلي ومعرفته في تدريس أحد فروع اللغة العربية.

The current research aims to know the complementary use of the paper book and the digital book by defining the paper book and the digital book and knowing the methods and methods of obtaining each of them and indicating the extent of their use and for what purpose and knowing the difficulties that researchers face in using each of them and which is better using the paper book or the digital book in preparing research Studies and for no reason. The research relied on the descriptive approach and the questionnaire as a tool for data collection, and it was distributed to professors and students of Iraqi universities. The research sample reached (219) individuals and reached a set of results, the most important of which are: Preference for the

The genetic algorithmmethod was employed in estimating the parameters of the maximum likelihood method as well as the Bayes method. The comparison was made using the mean error squares (MSE), where the best estimator is the one who has the least mean squared error. It was noted that the best estimator was (BLG_GE).
Abstract
This research aim to overcome the problem of dimensionality by using the methods of non-linear regression, which reduces the root of the average square error (RMSE), and is called the method of projection pursuit regression (PPR), which is one of the methods for reducing dimensions that work to overcome the problem of dimensionality (curse of dimensionality), The (PPR) method is a statistical technique that deals with finding the most important projections in multi-dimensional data , and With each finding projection , the data is reduced by linear compounds overall the projection. The process repeated to produce good projections until the best projections are obtained. The main idea of the PPR is to model

Quality control is an effective statistical tool in the field of controlling the productivity to monitor and confirm the manufactured products to the standard qualities and the certified criteria for some products and services and its main purpose is to cope with the production and industrial development in the business and competitive market. Quality control charts are used to monitor the qualitative properties of the production procedures in addition to detecting the abnormal deviations in the production procedure. The multivariate Kernel Density Estimator control charts method was used which is one of the nonparametric methods that doesn’t require any assumptions regarding the distribution o
