يهدف البحث الحالي إلى التحريّ عن صعوبات مادة الامريكيتين ، من وجهة نظر طالبات قسم الجغرافية في كلية التربية للبنات بجامعة بغداد ، تكوّن مجتمع البحث من طالبات المرحلة الثالثة و البالغ عددهن (230) طالبةً ، و لتحقيق هدف البحث اختارت الباحثة الاستبانة كأداةٍ للدراسة ؛ باعتبارها الأداة الأنسب في عملية جمع البيانات النهائية ، و الأكثر شيوعاً بين البحوث التربوية و النفسية ، فضلاً عن الاطلاع على الدراسات التربوية السابقة ذات العلاقة بموضوع البحث الحالي للإفادة منها في إعداد أداة البحث ، و في ضوء ذلك اختارت الباحثة عيّنةً استطلاعية بصورة عشوائية بلغ عددها (30) طالبة ، شكّلت نسبة (0.13) من المجتمع الأصلي ، و وجهت لهنَّ سؤالاً مفتوحاً بهدف التعرف على آرائهنَّ ، و الحصول على أكبر عدد من الصعوبات التدريسية من وجهة نظرهنَّ ، و بعد جمع البيانات الخاصة باستجابات الطالبات تم تصنيف الصعوبات الى خمسة مجالات رئيسة هي ( المادة العلمية- الطالبات- تدريسي المادة - طرائق و أساليب التدريس- أساليب التقويم) بواقع (6) فقرات لكلِّ مجال ، تم احتساب صدق فقراتها بعرضها على مجموعة من المحكّمين و المتخصصين في العلوم التربوية و النفسية و الجغرافية لتحديد مدى صلاحيتها، كما تم حساب ثباتها بطريقة (إعادة تطبيق الاختبار) على عيّنة استطلاعية بلغت (25) طالبة ، اختيرت بطريقة عشوائية شكّلت نسبة مقدرها (0.12) من المجتمع الأصلي المتبقي البالغ (200) طالبة ، و قد تم اعتماد (معامل ارتباط بيرسون) لحساب معامل الثبات ، و لمعرفة صعوبات تدريس مادة الامريكيتين من وجهة نظر الطالبات ، تم تطبيق أداة البحث على عيّنة البحث والبالغة (50) طالبة ، تم اختيارهن بطريقة عشوائية ، و باستخدام المنهج الوصفي التحليلي، و جمع البيانات و تحليلها إحصائياً باستعمال الوسائل الآتية (معادلة فيشر لحساب الوسط المرجح و الوزن المئوي لتحديد الوزن المئوي الخاص بفقرات مجالات الأداة ) ، و بعد ترتيب مجالات الأداة و فقراتها تنازلياً على وفق المعدل العام للوسط المرجح و النسبة المئوية توصلت النتائج الى : إنّ صعوبات مجال المادة العلمية كانت(أولاً) ، و صعوبات مجال طرائق و أساليب التدريس (ثانياً) ، و صعوبات مجال تدريسي المادة (ثالثاً) ،و صعوبات مجال أساليب التقويم (رابعاً) ، و صعوبات مجال الطالبات (خامساً) ، حيث تراوحت قيم أوساطها المرجحة بين (2.04) و(1.74) ، و أوزانها المئوية بين (68.08) و(58.08) على التوالي.
Three-dimensional (3D) reconstruction from images is a most beneficial method of object regeneration by using a photo-realistic way that can be used in many fields. For industrial fields, it can be used to visualize the cracks within alloys or walls. In medical fields, it has been used as 3D scanner to reconstruct some human organs such as internal nose for plastic surgery or to reconstruct ear canal for fabricating a hearing aid device, and others. These applications need high accuracy details and measurement that represent the main issue which should be taken in consideration, also the other issues are cost, movability, and ease of use which should be taken into consideration. This work has presented an approach for design and construc
