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.
A solar updraft tower power plant (solar tower) is a solar thermal power plant that utilizes a combination of solar
air collector and central updraft tube to generate an induced convective flow which drives pressure staged turbines to generate electricity.
This paper presents practical results of a prototype of a solar chimney with thermal mass, where the glass surface is replaced by transparence plastic cover. The study focused on chimney's basements kind effect on collected air temperatures. Three basements were used: concrete, black concrete and black pebbles basements. The study was conducted in Baghdad from August to November 2009.
The results show that the best chimney efficiency attaine

The paper attempts to fill a gap in research literature concerning the linguistic construction of the Iraqi child by the UNICEF reports during the critical health crisis of Covid19. Van Leeuwen’s (2008) approach of social actor representation has been adopted for this purpose. From Van Leeuwen’s approach, the category of determination (single determination and overdetermination) has been selected to be the main analytical tool for its high compatibility with the set of objectives put forward to figure out how such a globally effective and

The availability of these metals in the human body may perform many biochemical functions and some of them linked with various diseases at high levels. The current study aimed to evaluate the concentration of various metals in common local consumed vegetables using ICP-MS. The concentrations of metals in vegetables of tarragon, Bay laurel, dill, Syrian mesquite, vine leaves, thymes, arugula, basil, common purslane and parsley of this study were found to be in the range of, 76-778 for Al, 10-333 for B, 4-119 for Ba, 2812-24645 for Ca, 0.1-0.32 for Co, 201-464 for Fe, 3661-46400 for K, 0.31–1.

In the story "In the Youth of Moses", he inter-texted the episode of the Prophet Moses from the Torah, the Source of legislation, to signify a legislative issue needed by the community. As for the story of "Samson, One of the Falling", he originated the character of The Judge Samson by alluding to the Book of the Judges, which is the Book which reminded of the defeat and slavery of the Palestinians by a Jewish leader, as is related in Jewish religious texts. Further, and the story of "And Haman Said", he chose the story of the Queen Esther from the Book of Esth

The antibacterial activity for the different concentrations of RR31 dye against different bacterial species was studied. The experimental data indicates that this dye acts as a potential inhibitor for carbon-steel in acetic acid medium and the protection efficiency increase with increasing (RR31) dye. The adsorption of (RR31) dye on the carbon steel surface was found to follow Langmuir adsorption isotherm. Thermodynamic data for the adsorption process such as Gibbs free energy change ∆Gads, enthalpy change ∆Hads, and entropy change ∆Sads were estima

Naproxen(NPX) imprinted liquid electrodes of polymers are built using polymerization precipitation. The molecularly imprinted (MIP) and non imprinted (NIP) polymers were synthesized using NPX as a template. In the polymerization precipitation involved, styrene(STY) was used as monomer, N,N-methylenediacrylamide (N,N-MDAM) as a cross-linker and benzoyl peroxide (BPO) as an initiator. The molecularly imprinted membranes and the non-imprinted membranes were prepared using acetophenone(AOPH) and di octylphathalate(DOP)as plasticizers in PVC matrix. The slopes and detection limits of the liquid electrodes ranged from)-18.1,-17.72 (mV/decade and )4.0 x 10-
