صعوبات تدريس مادة الكيمياء الكمية في قسم الكيمياء - كلية التربية - للعلوم الصرفة من وجهة نظر تدريسي المادة و الطلبة
...Show More Authors

تعد أساليب وطرائق تدريس المواد الدراسية العلمية من المجالات المهمة التي تساعد في تحويل المجرد إلى ثوابت في الذهن وترفع مستوى خبرات كل من المعلم والمتعلم على حد سواء إضافة إلى إنها جزء لا يتجزأ من العملية التربوية ومن الركائز المهمة التي تقوم عليها المناهج الدراسية لأنها تساعد الطلبة على اكتساب مهارات ومعلومات وتكوين اتجاهات وميول تخدم أهداف تدريس المادة وبما أن مادة الكيمياء الكمية هي إحدى المواد الدراسية المهمة التي تدرس في قسم الكيمياء- كلية التربية- للعلوم الصرفة المرحلة الرابعة لذا كان لابد من الاهتمام بها والوقوف على الصعوبات التي تحد من تحقيق أهدافها الدراسية من أجل التخلص منها وبما ينعكس إيجاباً على العملية التعليمية من خلال تطوير كفاءة مدرسيها بشكل جيد لخدمتها وهذا ما أكده استطلاع للرأي لبعض التدريسيين الذين يدرسون هذه المادة والطلبة الذين يدرسونها لذا كان من الضروري تحديد صعوبات تدريس مادة لكيمياء الكمية والوصول إلى مجموعة الحلول والمقترحات من وجهة نظر المدرسين والطلبة معاً للتخلص من صعوبات تدريس هذه المادة

Mass Transfer Coefficient During Cathodic Protection of Low Carbon Steel in Seawater
...Show More Authors

The aim of this research is to calculate mass transfer coefficient, kd, during cathodic protection of low carbon steel in neutral seawater (3.5% W/V NaCl in distilled water with pH = 7). Two types of cathodic protection were used:

First: Sacrificial anode cathodic protection (SACP) were a pipeline of steel carrying seawater  using zinc as a sacrificial anode and with variable temperatures ranged (0 – 45oC) and volumetric flow rate ranged (5 – 900 lit/hr). It was found that the kd increases with increasing temperature and volumetric flow rate of seawater, where kd ranged (0.24×10-6 – 41.6×10-6 m/s).

Second: Impressed current cathodic pr

Prediction of Surface Roughness and Material Removal Rate in Electrochemical Machining Using Taguchi Method
...Show More Authors

Electrochemical machining is one of the widely used non-conventional machining processes to machine complex and difficult shapes for electrically conducting materials, such as super alloys, Ti-alloys, alloy steel, tool steel and stainless steel.  Use of optimal ECM process conditions can significantly reduce the ECM operating, tooling, and maintenance cost and can produce components with higher accuracy. This paper studies the effect of process parameters on surface roughness (Ra) and material removal rate (MRR), and the optimization of process conditions in ECM. Experiments were conducted based on Taguchi’s L9 orthogonal array (OA) with three process parameters viz. current, electrolyte concentration, and inter-electrode gap. Sig

The Research aims to understand Student's attitudes towards Academic
Cheating in the Technical College -Baghdad. The study was made on a sample of
(88) students in the fourth (final) year who were randomly selected from the every
scientific department in the college. The researchers prepared academic cheating a
questionnaire. The research results showed that. The results showed that there is a
strong trend among the students to reject the cheating phenomenon. ( 72.72%) of
the specimen groups do not see that there is a justification in cheating, on the other
hand the results determined the means and reasons for the cheating by the students
and the negative outcome of that phenomenon.

Le présent travail aborde la question de l’enseignement de traduction en tant que matière faisant partie du programme élaboré dans des Départements de Français au sein de certaines universités irakiennes, en particulier celle de Bagdad. La méthode d’enseigner suivie constitue une véritable problématique qu’on a bien diagnostiquée à partir de quelques années d’expériences, à la lumière des observations faites dans des cours de traduction professionnelle, et dans la perspective des citations et témoignages établies par des traductologues et pédagogues et principalement par Marianne LEDERER qui a établi la Théorie Interprétative de la traduction. Mais pourquoi l’enseignement lui-même poserait une telle probl
