التعلم التعاوني وأثره على التحصيل والاتجاه نحو الحاسب الآلي عند طلبة كلية التربية بجامعة بغداد
...Show More Authors

هدفت هذه الدراسة إلى مقارنة أثر أسلوب التعلم التعاوني بالأسلوب التقليدي في التحصيل الدراسي، وعلاقته بالاتجاه نحو الحاسب الآلي عند طلبة كلية التربية بجامعة بغداد خلال دراستهم لمقرر الحاسب الآلي وقد تضمنت إجراءات الدراسة استخدام الأسلوب التجريبي، وذلك بتوزيع أربع شعب دراسية على مجموعتين: "مجموعة تجريبية" يتم تدريسها باستخدام أسلوب التعلم التعاوني، والمجموعة الثانية: "مجموعة ضابطة" يتم تدريسها بالطريقة التقليدية. وقد استخدم في هذه الدراسة مقياسان: الأول اختبار لقياس التحصيل الدراسي، والآخر استبانة لقياس الاتجاه نحو الحاسب الآلي. وقد تضمنت استبانة الاتجاه أربعة محاور، هي: الرأي تجاه الحاسب، القلق من الحاسب، والوعي بأهمية الحاسب، والخوف من دراسة المقرر. وقد تم تطبيق المقياسين مرتين: الأولى في بداية الفصل الدراسي، والذي نتج عنه عدم وجود فروق ذات دلالة إحصائية بين الطلبة سواء في معلوماتهن عن الحاسب، أو في اتجاههن نحوه، أو في خوفهن من دراسة مقرر الحاسب الآلي، ولكن ظهر تخوف كبير من قبل أغلبية أفراد العينة في محور الخوف من دراسة المقرر. أما التطبيق الثاني فكان في نهاية الفصل الدراسي، وأظهرت النتائج وجود فروق ذات دلالة إحصائية في كل من مستوى تحصيل الطلبة، وفي الثلاثة محاور الأولى من مقياس الاتجاه نحو الحاسب وذلك لصالح المجموعة التجريبية. أما المحور الرابع "الخوف من دراسة المقرر" فلم يظهر فرق ذو دلالة إحصائية بين المجموعتين يمكن إرجاعه إلى أسلوب التعلم، غير أن الفرق ظهر في ارتفاع متوسط الدرجات لأغلب أفراد العينة ما بين بداية الفصل الدراسي ونهايته، الأمر الذي أكد على أن مجرد تعلم الحاسب بغض النظر – عن الطريقة المتبعة – ساعد في تقليل الخوف من الدراسة عن الحاسب الآلي. أما الأسلوب التعاوني فكان عاملاً مساعداً في زيادة التحصيل الدراسي وبناء اتجاه جيد نحو الحاسب الآلي.

Unipolarity and Its Influences in American Foreign Policy and the Future International Relations: Unipolarity and Its Influences in American Foreign Policy and the Future International Relations

Abstract
The concept of unipolar has allowed the united states of America to
control the rest of the internations community units through the rxclusively of
control in international affairs without enabling other countries who have the
ability to compete with it to appear this comes as a result of it's position to all
kinds of powers like military, economic and technical powers that enable it to
continue dominating other countries, this superior control enabled it to be the
(hyper power) on the international political scene so that it allowed it to
exercise and implement the policy of domination against all this appeared
after its empire superiority became clear, in a unique way that have never
been known in

The effect of increasing the volume of debt on the volume of trading (applied research on a sample of private banks listed on the Iraq Stock Exchange)
...Show More Authors

 

This research worked on identifying the effect of increasing the volume of indebtedness by companies listed on the Iraq Stock Exchange on the trading volume of those companies, and this research included some theoretical concepts related to both debt financing and trading volume, and it represents the research community of the joint-stock companies listed in The Iraq Stock Exchange (the banking sector). As for the research sample, it was deliberately chosen represented by companies with continuous trading without stopping, which reached 10 joint-stock companies, and the period of research was extended during the period 2011-2015, and a set of indicators and financial methods were used In measuring research v

Design of Nonlinear PID Neural Controller for the Speed Control of a Permanent Magnet DC Motor Model based on Optimization Algorithm
...Show More Authors

In this paper, the speed control of the real DC motor is experimentally investigated using nonlinear PID neural network controller. As a simple and fast tuning algorithm, two optimization techniques are used; trial and error method and particle swarm optimization PSO algorithm in order to tune the nonlinear PID neural controller's parameters and to find best speed response of the DC motor. To save time in the real system, a Matlab simulation package is used to carry out these algorithms to tune and find the best values of the nonlinear PID parameters. Then these parameters are used in the designed real time nonlinear PID controller system based on LabVIEW package. Simulation and experimental results are compared with each other and showe

Abstract:
The Palestinian existence in Lebanan is regard as active Arab powers
in political system in Lebanan. This existence arises exactly in Lebanan on 5 /
June / 1967. The Palestinians distributed from south to north, from Bayrouth

to Al-Bquaa, also they lived in Camps like (Tal Al-Zater), (Aen Al-hlwa, Mya –
Mya) and so on.
The armed Palestinian resistance breakout from these camps in
Lebanan against Israel, Lebanon rejected this conflict to avoid any
confrontation with Israel which have big military and high ability in different
aspects in addition security of Lebanan did not connected with security of
Arab states in other side the civil war which break out in Lebanon impact upon

AN EXPERIMENTAL STUDY OF THE EFFECT OF VORTEX GENERATOR ON THE FLAT-PLATE BOUNDARY LAYER: AN EXPERIMENTAL STUDY OF THE EFFECT OF VORTEX GENERATOR ON THE FLAT-PLATE BOUNDARY LAYER
...Show More Authors

This paper is dealing with an experimental study to show the influence of the geometric characteristics of the vortex generators VG son the thickness of the boundary layer (∂) and drag coefficients (CD) of the flat plate. Vortex generators work effectively on medium and high angles of attack, since they are "hidden" under the boundary layer and practically ineffective at low angles.

            The height of VGs relative to the thickness of the boundary layer enables us to study the efficacy of VGs in delaying boundary layer separation. The distance between two VGs also has an effect on the boundary layer if we take into

Control of Omni-Directional Mobile Robot Motion
...Show More Authors

This paper presents the motion programming and control of omni-directional mobile robot through the process of building and programming a small robotic platform with secondary design criteria of modularity and simplified control. This is accomplished by combining the positive aspects of several different robotics platform ideas. The platform is shaped like an equilateral triangle with a servo motor, sensors, and omni-wheel, controlled by a PIC microcontroller.

      In this work the kinematics, inverse kinematics and dynamic module for the platform is derived. Two search algorithms (the wall-following search and the “most-open-area” search) is designed, tested, and analyzed experimentally.

Effect of Construction Joints on Performance of Reinforced Concrete Beams
...Show More Authors

Construction joints are stopping places in the process of placing concrete, and they are required because in many structures it is impractical to place concrete in one continuous operation. The amount of concrete that can be placed at one time is governed by the batching and mixing capacity and by the strength of the formwork. A good construction joint should provide adequate flexural and shear continuity through the interface.

In this study, the effect of location of construction joints on the performance of reinforced concrete structural elements is experimentally investigated.

Nineteen beam specimens with dimensions of 200×200×950 mm were tested. The variables investigated are the location of the construction joints

This study aimed at analyzing and studying the strategic and geopolitical importance of the Sahel region, which increased the regional competition for the resources of the region, especially the energy resources that have been and continue to be one of the axes of conflict and competition between these forces.
The researcher tried to review the competition between the international force, France, the United States of America, China, Algeria and Libya, and the African coast. We note that there is a positive correlation between the severity of the conflict and the intensity of the competition of the major powers to control the countries of the region and the extent of political and economic stability These countries are directly affecte
