تحليل محتوى كتاب الرياضيات للصف الاول المتوسط على وفق مكونات المعرفة
...Show More Authors

هدفت الدراسة الى تحليل محتوى كتاب الرياضيات للصف الاول متوسط على وفق مكونات المعرفة الرياضية (المفاهيم الرياضية , التعميمات الرياضية, المهارات الرياضية والمسائل الرياضية )

وتفرعت منه الاسئلة الاتية :

مانسبة المفاهيم الرياضية المتضمنة في كل فصل من فصول كتاب الرياضيات للصف الاول متوسط  وللكتاب ككل ؟

مانسبة المهارات الرياضية المتضمنة في كل فصل من فصول كتاب الرياضيات للصف الاول متوسط  وللكتاب ككل ؟

مانسبة التعميمات الرياضية المتضمنة في كل فصل من فصول كتاب الرياضيات للصف الاول متوسط  وللكتاب ككل ؟

مانسبة التمارين والمسائل الرياضية المتضمنة في كل فصل من فصول كتاب الرياضيات للصف الاول متوسط  وللكتاب ككل ؟

واستخدمت الباحثة المنهج الوصفي التحليلي لملائمته لطبيعة هدف البحث .

اعتمدت الباحثة النسب المئوية والتكرارات لتحديد مكونات المعرفة الرياضية المتضمنة في محتوى كتاب الرياضيات للصف الاول المتوسط واستخدمت معادلة ( Holiste) لحساب الثبات التحليل بين الباحثة ونفسها عبر الزمن وبينها وبين باحث اخر .

وقد توصلت الدراسة الى النتائج الاتية : نسب المفاهيم الرياضية (13,53%) وبتكرار (70) مفهوم من مجموع مكونات المعرفة الرياضية للكتاب ككل. نسب المهارات الرياضية (21,09%) وبتكرار (109) مهارة من مجموع مكونات المعرفة الرياضية للكتاب ككل . نسب التعميمات الرياضية (7,15%) وبتكرار (37) تعميم من مجموع مكونات المعرفة الرياضية للكتاب كله . نسب التمارين والمسائل الرياضية (58,23%) وبتكرار (301) تمرين ومسألة رياضية من مجموع مكونات المعرفة الرياضية للكتاب ككل .

وفي ضوء نتائج الدراسة اوصت الباحثة تطوير كتب الرياضيات للمرحلة المتوسطة بحيث يحقق محتواها الاهتمام بتدرج البناء الرياضي واهمها المفاهيم الرياضية التي هي اللبنات الاساسية لهذا البناء .

واقترحت الباحثة دراسة مدى التعرف على مطابقة مكونات المعرفة الرياضية في كتب الرياضيات للمرحلة المتوسطة على وفق معايير المجلس القومي لمعلمي الرياضيات  ( NCTM)

Study the Characterization of Adding Polymer-Surfactant Agent on the Drag Reduction Phenomena in Pipeline Flow System
...Show More Authors

  Abstract    

In this study, the effect of carboxylic methyl cellulose (CMC), and sodium dodcyl benzene sulfonate (SDBS) as an aqueous solution on the drag reduction was investigated. Different concentrations of (CMC) and (SDBS) such as (50, 100, 150, 200, 250, 300, 350, 400, 450, and 500 ppm) were used to analyze the aqueous solution properties, including surface tension, conductivity, and shear viscosity. The optimum four concentrations (i.e., 50, 100, 200, and 300 ppm) of fluid properties were utilized to find their effect on the drag reduction. Two different PVC pipe diameters (i.e., 1" and 3/4") were used in this work. The  results showed that blending CMC with SDBS gives

Mechanical and thermal properties of composites, consisted of unsaturated polyester resin, reinforced by different kinds of natural materials (Orange peels and Date seeds) and industrial materials (carbon and silica) with particle size 98 µm were studied. Various weight ratios, 5, 10, and 15 wt. % of natural and industrial materials have been infused into polyester. Tensile, three-point bending and thermal conductivity tests were conducted for the unfilled polyester, natural and industrial composite to identify the weight ratio effect on the properties of materials. The results indicated that when the weight ratio for polyester with date seeds increased from 10% to 15%, the maximum Young’s modulus decreased by 54%. When the weight rat
