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.

... Show MoreThe survival analysis is one of the modern methods of analysis that is based on the fact that the dependent variable represents time until the event concerned in the study. There are many survival models that deal with the impact of explanatory factors on the likelihood of survival, including the models proposed by the world, David Cox, one of the most important and common models of survival, where it consists of two functions, one of which is a parametric function that does not depend on the survival time and the other a nonparametric function that depends on times of survival, which the Cox model is defined as a semi parametric model, The set of parametric models that depend on the time-to-event distribution parameters such as

Methodology: A descriptive analytic (quasi – experimental) design study was carried out at Diabetic and Endocrinology Center in Baghdad- Rusafa Sector from 2nd of May 2017, to27th June 2018. Non-probability sample of (80) male and female diabetic patients were selected. The study instruments consisted of two major parts: first
In this research we study a variance component model, Which is the one of the most important models widely used in the analysis of the data, this model is one type of a multilevel models, and it is considered as linear models , there are three types of linear variance component models ,Fixed effect of linear variance component model, Random effect of linear variance component model and Mixed effect of linear variance component model . In this paper we will examine the model of mixed effect of linear variance component model with one –way random effect ,and the mixed model is a mixture of fixed effect and random effect in the same model, where it contains the parameter (μ) and treatment effect (τi ) which has

The research is important by analyzing the magnitude of the macroeconomic and especially GDP effects of these variables, as well as the economic effects of exchange rates on economic activity. The results of the standard analysis using the ARDL model showed a long-term equilibrium relationship, according to the Bound Test methodology, from explanatory (independent) variables to the internal (dependent) variable, while the value of the error correction vector factor was negative and moral at a level less than (1%). The relationship bet

This research aims to compare Bayesian Method and Full Maximum Likelihood to estimate hierarchical Poisson regression model.
The comparison was done by simulation using different sample sizes (n = 30, 60, 120) and different Frequencies (r = 1000, 5000) for the experiments as was the adoption of the Mean Square Error to compare the preference estimation methods and then choose the best way to appreciate model and concluded that hierarchical Poisson regression model that has been appreciated Full Maximum Likelihood Full Maximum Likelihood with sample size (n = 30) is the best to represent the maternal mortality data after it has been reliance value param

The most important results and recommendations of the study are as follows: a high rate of the respondents’, sample individuals, exposure to the dubbed Turkish series since it is evident that almost three-fourths of the study individuals watch the dubbed Turkish series,.”. The most significant positive aspects of the dubbed Turkish series are: “they focus on the most important tourist attractions in Turkey” and “ improving the audience›s knowledge and information on the traditions of the Turkish society”.

Show MoreThe aim of this research is to apply Throughput Accounting in improving the cost leadership strategy for the woven fabric department (polyester blended - polyester 150/1) in the Waist Textile and Knitting Factory. The problem of the research is that the research sample laboratory does not apply modern cost management methods represented in Throughput Accounting, as the Iraqi economic units suffer from their inability to compete in the labor market in light of the competitive environment. The Ministry of Interior improved the cost leadership strategy for the product of blended polyester and polyester fabrics 1/150. Through the research, a set of conclusions was reached, the most important of which are: Improving the cost lea
