أثر أنموذج لاندا في تحصيل طالبات الصف الخامس العلمي في مادة الاحياء
...Show More Authors

اظهرت نتائج ابحاث تربوية اجريت في الولايات المتحدة الامريكية ان تدريس مادة الاحياء يعتمد على حفظ المصطلحات والمفاهيم العلمية دون فهم واستيعاب لها، كما ان الاساليب والطرائق التدريسية المتبعة تقليدية وتؤكد على الجوانب الشكلية والنظرية والحفظ والتلقين. (عايش،1999،ص8).

        واشارت دراسة في وزارة التربية العراقية ان مادة الاحياء تشارك بعض المواد الاخرى في صعوبتها في المرحلة الثانوية لان المفاهيم الاحيائية لها خصوصية من حيث صعوبتها وتشابكها وتفرعها مما يزيد من صعوبة تعلمها.(العراق،1984،ص4-12). وتكمن مشكلة البحث من انخفاض مستوى تحصيل طالبات الصف الخامس العلمي في مادة الاحياء عند مقارنته بتحصيلهن في الصف الرابع العام، وقد يعود ذلك الى طبيعة مادة الاحياء المعقدة نوعا ما في هذا الصف لتضمينها مفاهيم ومبادئ،وقوانين ومسائل رياضية فسلجية تصعب على الطالبات ادراكها على وفق الاساليب التدريسية التقليدية الشائعة في مدارسنا(المحاضرة)، كما ان التركيز على التلقين وعدم ربط الخبرات السابقة للطالبات والتقييد الحرفي بالكتاب وعدم توظيف المفاهيم الاحيائية بصورة جيدة.        إضافة الى عدم جدية التدريس من قبل اغلب المدرسات وعدم استعمال التقنيات الحديثة انعكست هي الاخرى على تحصيل الطالبات وهذا ما لاحظه الباحث من خلال خبرته المتواضعة وعند زيارته للمدارس الثانوية عند التطبيق الجمعي.

        كما وجه الباحث سؤالاً الى (50) مدرس ومدرسة احياء حول معرفتهم لانموذج لاندا وكيفية استعماله في التدريس، فكانت أجابتهم جميعا بعدم معرفتهم بهذا النموذج وانهم اعدو لاعطاء المحاضرات حسب الطرائق المتبعة (التقليدية).

لذا جاء البحث في اثارة السؤال الاتي:-

هل لانموذج لاندا اثر في تحصيل طالبات الصف الخامس العلمي في مادة الاحياء؟

Abstract

 

Theoretical and experimental methodologies were assessed to test curved beam made of layered   composite material. The maximum stress and maximum deflection were computed for each layer and the effect of radius of curvature and curve shape on them. Because of the increase of the use of composite materials in aircraft structures and the renewed interest in these types of problems, the presented theoretical assessment was made using three different approaches: curved beam theory and an approximate 2D strength of material equations and finite element method (FEM) analysis by ANSYS 14.5 program for twelve cases of multi-layered cylindrical shell panel differs in fibe

Effect of Solid Loading on Carbon Dioxide Absorption in Bubble Column
...Show More Authors

In the present work experiments were conducted to study  the effect of solid loading (1,5 and 9 vol.%) on the enhancement of carbon dioxide absorption in bubble column at various volumetric gas flow rate (0.75, 1 and 1.5 m3/h) and absorbent concentration (caustic soda)( 0.1,0.5 and 1 M  ). Activated carbon and alumina oxide (Al2O3) are used as solid particles. The Danckwerts method was used to calculate interfacial area and individual mass transfer coefficients during absorption of carbon dioxide in a bubble column. The results show that the absorption rate was increased with increasing volumetric gas flow rate, caustic soda concentration and solid loading. Mass transfer coefficient and interfac
