This research aims to identify the effect of numbered heads strategy on developing oral expression skills among fifth-grade primary students in Bisha Province. To achieve this, the researcher prepared a research tool represented in the observation card which consists of (27) statements distributed in four axes. The tool was sent to (5) experts in the field to verify their validity. In light of their corrections, the tool was developed to be valid for gathering field information. To verify the validity of the content and the reliability of the tool, the researcher applied it to a sample consists of (20) students from outside the research group. The overall coefficient of correlation between the statements of the tool is as follows: (.95, .93, .87, .88). The researcher also made an equation (Alpha Cronbach). The reliability of the tool was ranged between (0.72, - 0.86) at the level of the four tool axes, it was reached at the level of the tool as a whole (0.94), which indicates that the tool is of a high degree of reliability, and the results of the research can be trusted on. The research was applied in the field at Al-Rafaya School, one of the primary schools, which belongs to the Central Education Office in Bisha Province, during the first term of the year 1440/1441 H. After applying the tool and analyzing its data, the results revealed a statistically significant difference at the significance level (0.01) between the average of the experimental group scores and the control group, in favor of the experimental group in oral expression skills in the four tool axes. The researcher used the Cohen equation to calculate the effect size. The results revealed that the value of (Z) is ranged from (3.80 to 4.50) between the control and experimental research group; all of them are significant values at the level of significance (0.01) according to Cohen's equation. The findings resulted in the positive impact of the numbered head strategy among the experimental research group in developing their oral expression skills, where the positive ranks were greater than the negative ranks in all research axes. In light of these results, the researcher presented a set of recommendations.
تهدف هذه الدراسة إلى استقصاء العلاقة الديناميكية بين التحولات السياسية والحراك الشعبي وتأثيرهما في تجسيد الزيارة الأربعينية في العراق، من خلال تحليل تطورها الرمزي وتفاعلها مع سياسات الحكومات العراقية المتعاقبة منذ تأسيسها عام 1921 وحتى مرحلة ما بعد 2003. تُفصل الدراسة كيفية تعامل السلطات العراقية المتعاقبة مع الزيارة الأربعينية، مع تسليط الضوء على اعتبار الزيارة منبراً للتعبير عن الحراك الشعبي والرفض للإجرا

The research aims to measure the net nominal protection coefficients for the products table eggs and poultry meat and the extent of its impact on domestic production volume for the period of 1990- 2013 has been the use of mathematical formulas simplified in the calculation of the transaction process with a view to the extent of support and protection offered by the state pricing policy for products Resources Sector Animal in Iraq and reach search Highlights and most important, there are volatile price state policy with regard to eggs and poultry meat, as it ranged net nominal protection coefficients between the larger and less than the right one, which means that values are unstable to support local producers or consumers, and can be The

Aims of the study: To evaluate the distribution of developmental dental anomalies according to age and gender in relation to nutritional status in children attending College of Dentistry /University of Baghdad. Materials and method: After examination 5760 children aged 5-12 years of both genders only 147child with dental anomalies were found, all developmental dental anomalies that were clinically observable were recorded. The developmental dental anomalies which diagnosed in this study were supernumerary, missing teeth,

Background Many antidiabetic medications with distinct modes of action are available, The sodium glucose cotransporter-2 (SGLT-2) inhibitors are among the most recent oral antihyperglycemic medications. The American Diabetes Association recommends metformin, a biguanide medication, as the first option for oral control of type 2 diabetes because it has demonstrated promise in this regard. Aim of the study To evaluate and compare the effects of metformin and SGLT-2 inhibitors on general urine parameters in T2DM patients from Iraq. Method a prospective cohort study where 101 adult patients of both sexes aged under 70 years and newly diagnosed with T2DM, patients were divided into two groups, Metformin group (n=52), where metformin was p

Background: Polymethyl methacrylate (PMMA) is the most commonly used material in denture fabrication. The material is far from ideal in fulfilling the mechanical requirements. Midline fracture; poor thermal conductivity and water sorption, are common problem in this material. The purpose of this study was to evaluate the effect of addition of surface treated Aluminum oxide nano fillers on some properties of heat cured (PMMA). Materials and methods: In addition to controlled group of heat cured PMMA the silanized (Al2O3) nanoparticles was added to PMMA powder by weight in three different percentages 1wt%, 2wt% and 3wt%, mixed by probe ultra-sonication machine. 200 specimens were constructed and divided into 5 groups according to the test (e
