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
Education received the attention of the monarchy in Iraq, especially after the developments that the country witnessed after Iraq gained independence and joined the League of Nations in 1932 AD in all political, economic and cultural aspects. In this regard, due to its distinguished geographical location, where the atmosphere, the natural environment and the religious and political standing were available, which made it a center of attraction for most Iraqi families and political figures. Learning and pioneering the path of knowledge, so it witnessed a great prosperity in secondary education, so several important schools appeared that contributed to advancing the wheel of learning forward, including Baghdad College High Schoo
... Show MoreThe present paper addresses one of the most challenging topics in translation; namely legal translation in the framework of two different approaches; the classical (formal) and the more recent (functional). The latter approach is the outcome of the process of simplifying legal language known technically as Plain Language Movement. The advent of this movement dates back to the 1950s, in response to the widely-held complain about the awkwardness of the legal register. Within this framework, the salient features of legal language, at the various linguistic and textual levels, underwent reconsideration in favor of more publicly digested expressions. The paper then subjects two translations of a lease contract to analysis in the ligh

Show MoreThis study discussed a biased estimator of the Negative Binomial Regression model known as (Liu Estimator), This estimate was used to reduce variance and overcome the problem Multicollinearity between explanatory variables, Some estimates were used such as Ridge Regression and Maximum Likelihood Estimators, This research aims at the theoretical comparisons between the new estimator (Liu Estimator) and the estimators
The research aims at identify the role of the electronic trading system used in the Iraq stock exchange to promote trading activity for the stocks of listed companies in this market.
To prove the hypothesis of research, it was selected the main trading indicators for the market to be a main field in test the research hypothesis.it was selected as the period of time for (9)years span between the years (2005-2013) because they represent the first two articles of equal time periods represent aperiod that preceded the introduction of electronic trading system while the second represents the period of time that followed

... Show MoreCloth simulation and animation has been the topic of research since the mid-80's in the field of computer graphics. Enforcing incompressible is very important in real time simulation. Although, there are great achievements in this regard, it still suffers from unnecessary time consumption in certain steps that is common in real time applications. This research develops a real-time cloth simulator for a virtual human character (VHC) with wearable clothing. This research achieves success in cloth simulation on the VHC through enhancing the position-based dynamics (PBD) framework by computing a series of positional constraints which implement constant densities. Also, the self-collision and collision wit

child health through the evaluation of impact and coverage health indicators and to evaluate the usefulness of the
application of these indicators at sub primary health care centers in Baghdad City.
Methodology: A descriptive comparative design, which is using the evaluation approach, has been steered at
Sub Primary Health Centers of Baghdad City in order to evaluate the application; impact and coverage, and the
usefulness of monitoring indicators for maternal, newborn and child health from December 4th 2017 to April 29th
