اثر استخدام المختبر العلمي
...Show More Authors

أن التقدم والتطور العلمي اللذين حدثا خلال القرن العشرين كان لهما اثر كبير في المسيرة العلمية ، حيث أن من المفترض على أفراد مجتمع المتعلمين أن يتزودوا بمهارات التفكير العلمي لكي تمكنهم من العيش في العصر الحالي وليشاركوا فيه بذكاء وفاعلية حتى يحققوا لذاتهم ملائمة أفضل مع التغييرات والتطورات المختلفة التي حدثت في العالم لذا فان طرائق التدريس أصبحت حاجة ملحة لا تقل أهميتها عن المدرس والمادة الدراسية حيث أكدت جميع المؤتمرات والندوات إتباع طرائق التدريس الحديثة ورفع الكفاية التعليمية للمتعلم فكانت طريقة الاستكشاف من بين هذه الطرائق التي يكشف بواسطتها الطالب الأشياء بنفسه ويوضح المكثف الأول وليجد بنفسه سبيله إلى المعرفة . ويهدف البحث الى معرفة اثر استخدام المختبر الاستكشافي في التفكير العلمي لدى طلبة معهد الطب التقني في مادة الإحياء المهجرية من خلال التحقق من الفرضية الصفرية لا يوجد فرق ذو دلالة إحصائية بين متوسط درجات التفكير العلمي المجموعة التجريبية التي تستخدم الطريقة الاستكشافية والمجموعة الضابطة التي تستخدم المختبر التقليدي ، ثم استخدام التصميم التجريبي ذات الاختبار ألبعدي حيث تحدد البحث الحالي بطلبة معهد الطب التقني للعام الدراسي 2007- 2008 حيث اختيرت الشعبتين أ- ب عشوائياً ، اذ  بلغ عدد العينة (62) طالباً وطالبة وبواقع (32) طالب وطالبة للمجموعة التجريبية اما المجموعة الضابطة فعددها (30) طالب وطالبة وكوفئت في متغيرات ( العمر ، التحصيل الدراسي السابق لمادة الأحياء ، الذكاء ) وتم تحقيق من معامل الصعوبة والسهولة والقوة التميزية وحساب معامل الثبات باستخدام  معادلة كودرريتشاردسون  حيث بلغ عدد الثبات (87، 0 ) للفقرات الموضوعة في الاختبار ، حيث أظهرت النتائج تفوق المجموعة التجريبية التي درست مادة الإحياء المهجرية وفق الطريقة الاستكشافية على المجموعة الضابطة حيث ان استخدام الطريقة الاستكشافية تؤدي الى تنمية مهارات التفكير العلمي وتقترح الباحثة أجراء دراسة تتناول اثر استخدام المختبر الاستكشافي بمتغيرات أخرى مثل تنمية التفكير ألابتكاري وتنمية التفكير الناقد .

Transportation problems are considered as a type of operation research problems. In fact, they deal with scheduling transportation of goods from their source to delivery sites in the minimum cost.

Such problems can be solved by the available traditional methods, which include; North-West corner, Least cost and Vogel’s method. As well as if this transportation problem is considered as a linear program it can also be solved by using Simplex method

The goal of the present study is to compare different research methods to provide the optimal and minimum cost.

This study was applied to resolve a transportation problem related to land Transportation Company, w

Reverse Engineering Representation Using an Image Processing Modification
...Show More Authors

In the reverse engineering approach, a massive amount of point data is gathered together during data acquisition and this leads to larger file sizes and longer information data handling time. In addition, fitting of surfaces of these data point is time-consuming and demands particular skills. In the present work a method for getting the control points of any profile has been presented. Where, many process for an image modification was explained using Solid Work program, and a parametric equation of the profile that proposed has been derived using Bezier technique with the control points that adopted. Finally, the proposed profile was machined using 3-aixs CNC milling machine and a compression in dimensions process has been occurred betwe
