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.

Enhancing Smart Cities with IoT and Cloud Computing: A Study on Integrating Wireless Ad Hoc Networks for Efficient Communication
...Show More Authors

Smart cities have recently undergone a fundamental evolution that has greatly increased their potentials. In reality, recent advances in the Internet of Things (IoT) have created new opportunities by solving a number of critical issues that are allowing innovations for smart cities as well as the creation and computerization of cutting-edge services and applications for the many city partners. In order to further the development of smart cities toward compelling sharing and connection, this study will explore the information innovation in smart cities in light of the Internet of Things (IoT) and cloud computing (CC). IoT data is first collected in the context of smart cities. The data that is gathered is uniform. The Internet of Things,

Effect of Public Debt on The Trade Balance in Iraq For The Period (2003-2021)
...Show More Authors

Despite the significant increase in public spending in Iraq, it was not directed toward the important sectors that have an important role in correcting the productive structure. Rather, most of the public expenditure was going to cover the required imports, or to face shocks, whether security or health, and this caused a continuous decrease in the volume of Iraq's exports of goods and services, as the aim of the study was to review the importance of public debt and its impact on the trade balance, as well as to know the economic policies that can contribute to strengthening the trade balance, as the study proved through the (ARDL) model that there is a direct relationship between the domestic debt and the net trade balance, and an invers

The influences of fashion on the design of fabrics and fashion at the time of contemporary social transformations
...Show More Authors

The design of fabrics and fashion is manifested by aesthetic advantages betting with the movement of society in its quest to develop as an independent art in itself that is linked to the values and aesthetic concepts of other arts and what appears in them of intellectual systems calling for renewal and modernity. Which brought about a wide change in public taste, as well as a desire for innovation . Which made fashion an interesting aesthetic phenomenon and taste is always subject to change constantly to comply with the social variables that occur in human life, as the fashion that appears in a certain era of time and takes a great distance from spreading as something new and out of the ordinary is in fact the fruit of the development of

Arabic Speech Classification Method Based on Padding and Deep Learning Neural Network
...Show More Authors

Deep learning convolution neural network has been widely used to recognize or classify voice. Various techniques have been used together with convolution neural network to prepare voice data before the training process in developing the classification model. However, not all model can produce good classification accuracy as there are many types of voice or speech. Classification of Arabic alphabet pronunciation is a one of the types of voice and accurate pronunciation is required in the learning of the Qur’an reading. Thus, the technique to process the pronunciation and training of the processed data requires specific approach. To overcome this issue, a method based on padding and deep learning convolution neural network is proposed to

Minimum Neighborhood Domination of Split Graph of Graphs
...Show More Authors

Let  be a non-trivial simple graph. A dominating set in a graph is a set of vertices such that every vertex not in the set is adjacent to at least one vertex in the set. A subset  is a minimum neighborhood dominating set if  is a dominating set and if for every  holds. The minimum cardinality of the minimum neighborhood dominating set of a graph  is called as minimum neighborhood dominating number and it is denoted by  . A minimum neighborhood dominating set is a dominating set where the intersection of the neighborhoods of all vertices in the set is as small as possible, (i.e., ). The minimum neighborhood dominating number, denoted by , is the minimum cardinality of a minimum neighborhood dominating set. In other words, it is the

Comparison of Faster R-CNN and YOLOv5 for Overlapping Objects Recognition
...Show More Authors

Classifying an overlapping object is one of the main challenges faced by researchers who work in object detection and recognition. Most of the available algorithms that have been developed are only able to classify or recognize objects which are either individually separated from each other or a single object in a scene(s), but not overlapping kitchen utensil objects. In this project, Faster R-CNN and YOLOv5 algorithms were proposed to detect and classify an overlapping object in a kitchen area.  The YOLOv5 and Faster R-CNN were applied to overlapping objects where the filter or kernel that are expected to be able to separate the overlapping object in the dedicated layer of applying models. A kitchen utensil benchmark image database and
