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.
Toxoplasma gondii is an opportunistic parasite in immune-compromised persons. The prevalence of toxoplasmosis in psoriasis patients is investigated. In addition, the treatment effect on psoriasis patients infected with toxoplasmosis through evaluating Tumor Necrosis Factor-α (TNF-α) cytokine levels is studied. Blood samples were collected from 130 individuals who involved 60 control samples and 70 samples with psoriasis. They attended Medical City Hospital in Baghdad province from October 2017 - February 2018. Then, the anti- T. gondii antibodies (IgM and IgG) and TNF- α in the sera were determined via the enzyme linked immune-sorbent assay. The highe

Show MoreIntellectual and material displacement is one of the design strategies through many mechanisms and means, and depends on the idea of changing the shape within the internal spaces at times and has concepts related to the transformation at other times. And represented by the boxes for travelers, the research problem emerged through the following question: (What is the effectiveness of displacement in the formal structures in the interior design of historical sites), and the aim of the study is to reveal the reality of the use of historical internal spaces and to determine the formal displacement that occurs as a result of change and transformation, and it included two topics, the first topic Transformation and the effectiveness of formal d

The series was tested for nonhomogenity and found to be nonhomogeneous. A significant positive jump was observed after 1988. This nonhomogenity was removed using a method suggested by Yevichevich (7). The homogeneous series was then normalized using Box and Cox (2) transformation. The periodic component of the series was fitted using harmonic analyses, and removed from the series to obtain the dependent stochastic component. This component was then modeled using first order autoregressive model (Markovian chain). The above a

In addition to identifying the strengths and weaknesses in portfolio's performance to enhance the strengths and address the weaknesses. This is consistent with research problem that dealt with the performance indicators, economic feasibility of company's portfolios and contributing to their improvement, reducing the financial and insurance risks associated with company's business. The research’ sample is represented by the Iraqi Insurance Company as it is one of the oldest financial institutions operating in the insurance sector. It has identified (5) insurance portfolios (marine, engineer

Television in Iraq is like any media outlet that adopts clear planning and programming in order to achieve the goals set in the news, entertainment, education. Iraq TV relies on four programming plans in one year (short term), but we often receive central instructions directly from the Minister of Information ordering to cancel the program plan and what was scheduled for broadcast to be finally replaced by alternative or emergency program associated with an incident, occasion or important news, these programs are all called (emergency programs).
In this present research we will be dealing with these programs as well as the extent of their impact o
... Show MoreSocieties developed throughout history with the development of life technology, that ideas presented by the contemporary art have been crystallized. The development included all the artistic fields such as the dramatic arts which depend on many effects and elements that led to the completion of the structure of the theater show. Scenography is considered one of the most important elements that the theatre show depends on such as the decoration, lighting, sound effects, costumes and accessories. The research addressed the following question: what are the characteristics and traits of scenography in the theatre show?
The research importance has become clear because it sheds lights on the characteristics of scenography in the Iraqi thea
In this research work, a simulator with time-domain visualizers and configurable parameters using a continuous time simulation approach with Matlab R2019a is presented for modeling and investigating the performance of optical fiber and free-space quantum channels as a part of a generic quantum key distribution system simulator. The modeled optical fiber quantum channel is characterized with a maximum allowable distance of 150 km with 0.2 dB/km at =1550nm. While, at =900nm and =830nm the attenuation values are 2 dB/km and 3 dB/km respectively. The modeled free space quantum channel is characterized at 0.1 dB/km at =860 nm with maximum allowable distance of 150 km also. The simulator was investigated in terms of the execution of the BB84 p

Controlling public expenditures is one of the main objectives of the public budget. The public budget often suffers from a deficit, whether in developed or developing countries, because expenditures are usually greater than the revenues generated. This requires the existence of financial rules that are adhered to by the government, which in turn leads to discipline. Fiscal policy leads to a reduction in the obligations incumbent on the government. Adhering to the financial rules would correct the course of fiscal policy in Iraq, with the need to direct oil revenues in the years of financial abundance when global oil prices rise to sovereign funds similar to other rentier countries, which contributes to maintaining the stabi
