Competitive swimming is a highly researched area and technological developments have aided advances in the understanding of the biomechanical principles that underpin these elements and govern propulsion. Moreover, those working in the sports field especially in swimming are interested in studying, analyzing, evaluating and developing motor skills by diagnosing the strengths and weaknesses of the skill, and accordingly, coaches and specialists correct these errors. The researchers chose this (Butterfly swimming) and the (arm length) is an important variable because the success of the stroke is greatly dependent on the propulsion generated from the arm pull, and swimmers with a longer arm span have a mechanical advantage with the resulting f

Considering the magnitude of its economic, social and political impact, unemployment represents a crucial challenge confronting the majority of the countries of the world. The problem of the study was the high rates of unemployment in Sudan and the inability of economic growth rates to keep pace with the steady increases in unemployment rates during the study period. This study aimed to identify the economic and social variables influencing unemployment rate in Sudan, in addition to measuring the impact of these variables over the period (1981-2015). Data were collected from databases of the World Bank and Atlas of the World's data .The study hypothesized the presence of statistically significant and direct relationship between u

המחקר הזה שופך אור על הנטוריליזם שהופיע בשנות ה- 60 במאה התשע עשרה כהמשיך לריאליזם וביטוי לתחושה בתנאים היסטוריים והחברתיים המורכבים ביותר,שידעו חברות במערב אירופה. נטורי ליזם היא דוקטרינה ספרותית בעלת סגנון אמנותי הנגזר מריאליזם אבל היא לשאת איתו את האופי הפילוסופי. לפיכך אנו יכולים להבין שהנטוריליזם היא כוחות חיצוניים וחברתיים המעכבים את חירות האדם,בניגוד לכוחות הגנטיים תת הכרתי שקובעים אחריות מוסרית ורצ

تهدف الدراسة إلى إبراز دور المدرسة الجغرافية الأمريكية في إعطاء الدراسات الإقليمية أهمية كبيرة، والمعروف عن المدرسة الأمريكية أنها تحتل وضعا مميزا في سياق الفكر الجغرافي رغم حداثتها إلا أنها استطاعت أن تثبت أقدامها بفضل اهتمامها بالدراسات الإقليمية منذ نشأتها إذ أن إظهار التباين بين مكان وأخر وبين زمن وأخر ضمن مساحة معينه أو حيز جغرافي بخصائص طبيعية، تاريخية، بشرية، ثقافية أو اقتصادية أو اجتماعية معينة كم

Standards play a vital role in documenting the values ​​of new test results in the form of tables. They are one of the basic requirements that the standardization process aims for as a complement to standardizing test procedures, and contribute to knowing the current reality of the student. The degree of readiness and level as a result of practicing different exercises for sports activities, in addition to the possibility of adopting it for comparison with his group or similar groups, classification, prediction and selection. Developing the skill of handling the football in the educational field is an important matter for achieving distinguished performance among students. This skill requires a level of accuracy, speed and control, and

The objective of the current research is to identify the effective of the suggested instructional design that based on the teaching strategy for understanding in achievement for students(girls) of mathematics in the fifth grads secondary school. To achieve the research goal, the empirical research method is depended. In this method a realistic empirical design pre-test of two equivalent sets to determine the students’ grade is used. The following zero hypotheses is formulated “There is no statistical difference for the faction at 0.05 between the mean grad for the students of the empirical group who studied the subject using the Instructional design based on the teaching strategy for understanding and those who studied the same subje

The research aims to identify the effect of teaching-learning design based on the constructivism theory on the life skills of middle stage students. The sample consisted of (60) students from one of the middle schools in Baghdad's governorate. The experimental group and control group consisted of 30 students for each group, the research tool was the life skills scale composed of (78) items. The scale proved its validity and reliability, which was found to be (0.85). The results showed a statistically significant difference in life skills between the two groups of research in favor of the experimental group, which studied the educational design according to models of constructivism theory compared to the usual method of teaching.
