يهدف هذا البحث إلى معرفة أثر استخدام دورة التعلم في اكتساب المفاهيم الصرفية واستخلاصها لدى طالبات قسم اللغة العربية بكلية التربية للبنات وقد صيغت فرضيتان مفادهما أن ؛ 1- لا توجد فروق ذات دلالة إحصائية بين متوسط درجات طالبات المجموعة التجريبية اللاتي يدرسن المادة الصرفية في دورة التعلم ومتوسط درجات طالبات المجموعة الضابطة اللاتي يدرسن المادة الصرفية بالطريقة القياسية لاكتساب المفاهيم. 2- لا توجد فروق ذات دلالة إحصائية بين متوسط درجات طالبات المجموعة التجريبية اللاتي يدرسن المادة الصرفية في دورة التعلم ومتوسط درجات طالبات المجموعة الضابطة اللاتي يدرسن المادة الصرفية بالطريقة القياسية لاكتساب المفاهيم. وقد اختارت الباحثة عمدياً قسم اللغة العربية بكلية التربية للبنات والذي يضم خمسة أقسام للمرحلة الأولى وقد اختير القسم (ب) عشوائياً للمجموعة التجريبية بينما مثل القسم (أ) المجموعة الضابطة وبلغت العينة (60) طالبة (30 طالبة) في كل من القسمين وقد تمت معادلتها باستخدام اختبار (AL-Taitest) في المتغيرات الآتية (العمر الزمني ودرجات المادة الصرفية في امتحان الفصل الدراسي الأول) ومربع (X) ودرجة التصحيح (نعم) في التحصيل الدراسي للوالدين. حدد الباحث موضوعات المادة العلمية التي ستتم دراستها في سياق التجربة وهي (8) موضوعات وأعد خطط دراسية لعرضها على مجموعة من الخبراء والمختصين وفي ضوء آرائهم تم دراسة موضوعات البحث من قبل الباحث نفسه واعد اختبارا تاليا مكونا من (30) فقرة اختيارية من نوع الاختيار من متعدد وعرض على مجموعة من الخبراء والمختصين للتحقق من صدق الاختبار وتحليل فقرات الاختبار وحساب ثباته وطبق على عينة بلغت (100) طالب وطالبة في المرحلة الأولى من قسم اللغة العربية بكلية التربية / الجامعة المستنصرية وبعد تحليل نتائج الإجابات ومعالجتها إحصائيا باستخدام الأدوات الإحصائية المناسبة تبين أن فقرات الاختبار صادقة ولحساب ثبات الاختبار تم استخدام أسلوب التجزئة شبه بعد معالجة بياناته باستخدام معامل ارتباط بيرسون والذي صحح صيغة سبيرمان – براون ليصبح (0.86) وهو معامل ثبات وقد بلغت درجة ثبات الاختبار التحصيلي (جيد جداً) وبعد انتهاء التجربة التي استمرت (8) أسابيع تم تطبيق الاختبار التحصيلي على طلاب مجموعتي البحث وبعد تحليل نتائج الإجابات تبين وجود فروق ذات دلالة إحصائية بين متوسط الدرجات (اكتساب المفاهيم والتلقين) لصالح مجموعتي البحث التجريبية التي درست مادة الصرف باستخدام دورة التعلم وفي ضوء نتائج البحث استنتج الباحث أن استخدام دورة التعلم فعال في تلقين المفاهيم الصرفية المتوازنة باستخدام الطريقة القياسية التقليدية وأوصى الباحث بتنويع طرق التدريس المستخدمة في مادة الصرف مع الاهتمام باستخدام دورة التعلم واقترح إجراء دراسات مماثلة على مراحل دراسية أخرى وبين المقررات الدراسية الأخرى.
Gastritis can be defined as histological inflammation of the gastric mucosa. It can be classified according to the time course of the disease as acute or chronic, histological findings, anatomic location, and pathological mechanisms. The objective of this study was to evaluation of serum levels of the proinflammatory cytokines IL-8, IL-17 and IL-22 in Helicobacter pylori infection and their association with the degree of gastritis histopathology in a sample of Iraqi patients. The case-control prospective study consists of 60 patients who attended the Gastrointestinal Tract Center at Al-Kindy Teaching Hospital during the period from December 2019 to April 2020. In addition, the control group included 60 apparently healthy individuals. Bio

Flavonoids were extracted from Zizyphus spina-christi leaves by Ethyl acetate after acid digested and used as antioxidant. The dried extract was added separately to each sample of fat extracted from hallow cow and sheep bones as follows: T1 cow fat, T2 control for cow fat, T3 sheep fat and T4 control for sheep fat (the control T2 and T4 reffered to samples without added antioxidant).
Samples were stored at -18, 5, 25 and 55 °C for 28 days. The storage trials were conducted at -18, 5 and 25 °C for 28 days for T1, T2, T3 and T4. The chemical indices examined initially and at the end of storage period. PVs was 1.46, 1.46, 1.8 and 1.8 meq/ Kg oil respectively, FFA values were 0.245, 0.245, 0.244 and 0.244% respectively and TBA va

Managing unstructured social media data is difficult. Noisy data is a challenge to sentiment analysis. Since over 50% of the sentiment analysis process is data pre-processing, processing big social media data is challenging too. If pre-processing is carried out correctly, data accuracy may improve. Also, sentiment analysis workflow is highly dependent. Because no pre-processing technique works well in all situations or with all data sources, choosing the most important ones is crucial. Prioritization is an excellent technique for choosing the most important ones. As one of many Multi-Criteria Decision Mak
