ملخص الدراسة
سعت الدراسة تعرف اثراستعمال الأنموذج المعملي في تصحيح المفاهيم الرياضية شائعة الخطأ لدى طلاب الصف الأول المتوسط بالإجابة عن السؤال "ما اثر استعمال الأنموذج المعملي في تصحيح المفاهيم الرياضية شائعة الخطأ لدى طلاب الصف الأول المتوسط" ولتحقيق هدف الدراسة وضعت الفرضية الصفرية "لايوجد فرق ذو دلالة إحصائية عند مستوى الدلالة (0.05) بين متوسطي درجات طلاب المجموعة التجريبية الذين يدرسون المادة المقررة باستعمال الأنموذج المعملي وطلاب المجموعة الضابطة الذين يدرسون المادة نفسها باستعمال الطريقة الاعتيادية في اختبار تشخيص المفاهيم الرياضية شائعة الخطأ" واختيرت ثانوية النهضة للبنين من مركز محافظة القادسية عشوائياً ميداناً لإجراء التجربة ومنها اختيرت عشوائياً شعبتين من الشعب الثلاث للصف الأول ، لتكون شعبة (أ) المجموعة التجريبية وعدد طلابها (33) طالباً وتدرس باستعمال الأنموذج المعملي في حين اصبحت شعبة (ب) تمثل المجموعة الضابطة وعدد طلابها (31) طالباً وتدرس باستعمال الطريقة الاعتيادية ، وبعد استبعاد الطلاب الراسبين البالغ عددهم (4) في المجموعة التجريبية و(3) في المجموعة الضابطة بلغ عدد طلاب المجموعة التجريبية بصورتها النهائية (29) طالباً ، أما المجموعة الضابطة فاصبح عدد طلابها (28) طالباً ، وتم التحقق من التكافؤ بين مجموعتي الدراسة في متغيرات التحصيل السابق في مادة الرياضيات والتحصيل العام للصف السادس الابتدائي واختبار الذكاء والعمر الزمني ، وطبقت التجربة في الفصل الدراسي الثاني من العام الدراسي 2009-2010 ، وفي نهاية الفصل الدراسي تم اختبار مجموعتي الدراسة باستعمال اختبار لتشخيص المفاهيم الرياضية شائعة الخطا لديهم بعد أن جرى التحقق من صدقه وثباته وحساب القوة التمييزية ومعامل الصعوبة وفعالية البدائل لفقراته ، ثم عولجت نتائج الاختبارإحصائيا باستعمال عدد من الوسائل الإحصائية مثل الاختبار التائي لعينتين مستقلتين ومعادلة كيودور ريتشاردسون -20 فضلاً عن تحليل التغايرالمصاحب ، وأظهرت النتائج تفوق طلاب المجموعة التجريبية التي درست باستعمال الأنموذج المعملي على طلاب المجموعة الضابطة التي درست باستعمال الطريقة الاعتيادية في تصحيح المفاهيم الرياضية شائعة الخطأ لديهم ، والتوصية باستعمال الأنموذج المعملي في تدريس المفاهيم الرياضية في المرحلة المتوسطة وتدريب المدرسين على كيفية استعماله عن طريق الدورات التدريبية ، فضلاً عن بعض المقترحات مثل إجراء دراسات تتناول الانموذج المعملي في متغيرات ومراحل دراسية اخرى
Crises affect the economic growth of the country in general and the banking sector in particular. Given the importance of this sector, it is necessary to evaluate the performance of banks from time to time and monitor the liquidity of each bank and how to organize its management to overcome any crisis or emergency situation that may befall it. The research seeks to diagnose the level of impact of crisis management. In the liquidity of Iraqi private banks, using liquidity indicators, as the research community represents the banks listed in the Iraq Stock Exchange As for the research sample, it is represented by (10) pri

The aim of this research is to identify the effectiveness of thinking skills in developing the life skills of the students of the first Academic year, particularly the differences in life skills according to the variable of study specialization (human-scientific). To achieve the research objectives, the life skills scale was constructed on the classification of (WHO). The psychometric properties of the scale were examined. The validity of the scale, which is the final form of (60) items, was valid for measuring the life skills. The scale was then applied to the research sample of (112) students of the first year of the University of Bisha. The SPSS program processed

Show MoreThe research is exposed to an important issue, related to communication obstacles that prevent the media message contained in cultural topics published in local newspapers to reach the hands of the readers; or related to lack of awareness of aspects of that media message, Because it contains immersed vocabulary in elitism where, sometime, the average reader of the newspaper of medium-sized educated, and even the academic reader are unable to decode it and understand its significance.
After determining the problem of the study and the tools that the researcher wants to use to accomplish his research, a sample of students of college of Arts at the University of Baghdad was selected. As they are clo

Show MoreIn this research, the stopping power and range of protons in biological human soft and hard tissues (blood, brain, skeleton-cortical bone, and skin) of both child and adult are calculated at the energies ranging from 1MeV to 350 MeV. The data is collected from ICRU Report 46 and calculated the stopping power employing the Bethe formula. Moreover, the simple integration (continuous slowing down approximation) method is employed for calculating protons range at the target. Then, the stopping power and range of protons value in human tissues have been compared with the program called SRIM. Moreover, the results of the stopping power vs energy and the range vs energy have been presented graphically. Proper agreement is found between the gain
