...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)

This study is pointed out to estimate the effectiveness of two solvents in the extraction and evaluating the active ingredients and their antioxidant activity as well as anti-cancer efficiency. Therefore, residues from four different Brassica vegetables viz. broccoli, Brussels sprout, cauliflower, and red cherry radish were extracted using two procedures methods: methanolic and water crude extracts. Methanol extracts showed the highest content of total phenolic (TP), total flavonoids (TF), and total tannins (TT) for broccoli and Brussels sprouts residues. Methanolic extract of broccoli and Brussels sprouts residues showed the highest DPPH· scavenging activity (IC50 = 15.39 and 18.64 µg/ml). The methanol and water ex
