هدف البحث التعرف على المتطلبات التدريبية لمدرسي المرحلة الإعدادية المتعلقة بمحتوى کتب الرياضيات واليات تنفيذه وفقا للمعايير العالمية , تَمَّ الاستعانة بالمنهج الوصفي التحليلي لتحليل محتوى ( (NCTM- المجلس القومي لمعلمي الرياضيات- لاعداد قائمة بمعايير الرياضيات المدرسية , کما استعان الباحثان بالمنهج الوصفي الدراسات المسحية لجمع المعلومات من مدرسي الرياضيات عينة البحث لتحديد المتطلبات التدريبية لديهم . تکونت عينة البحث من ( 30 ) مدرس ومدرسة من مدرسي مادة الرياضيات في المدارس الاعدادية والثانوية ( ممن يُدرسون المرحلة الاعدادية ) . قام الباحثان بإعداد أداة البحث المتمثلة باستبانة المتطلبات التدريبية تتکون من ( 34 ) فقرة تمثل کل منها مؤشرا لاحدى معايير الرياضيات المدرسية الخاص بمعايير المحتوى ومعايير العمليات کل فقرة يقابلها مقياس خماسي يتدرج من ( 5 -1) درجة يحدد المتطلب التدريبي وهي ( بدرجة کبيرة جدا , بدرجة کبيرة , بدرجة متوسطة , بدرجة قليلة , بدرجة قليلة جدا ) تم تطبيقها على عينة البحث في الفصل الدراسي الثاني للعام ( 2015 – 2016 م ). أستخدم الباحثان عدد من الوسائل الإحصائية المناسبة لإجراءات البحث و في تحليل النتائج. أظهرت نتائج البحث عدم وجود حاجة تدريبية لمدرسي الرياضيات في مجال الاعداد والعمليات عليها وهو احد مجالات محور معايير المحتوى , وان هناک حاجة تدريبية ملحة لمدرسي الرياضيات في باقي مجالات محور معاييرالمحتوى والواردة بالترتيب التنازلي الاتي : ( مجال الهندسة يليه مجال الجبروالدوال يليه مجال تحليل البيانات والاحتمال يليه مجال القياس ) , وفيما يخص محور معايير العمليات فقد أظهرت النتائج ان هناک حاجة ملحة لجميع مجالات محور العمليات والواردة بالترتيب التنازلي الاتي : (مجال التعليل والبرهان يليه مجال حل المشکلات يليه مجال التمثيلات الرياضية والاحتمال يليه مجال التواصل الرياضي يليه مجال الترابط الرياضي ) . وفي ضوء النتائج توصل الباحثان إلى العديد من الاستنتاجات والتوصيات والمقترحات .
Dapagliflozin is a novel sodium-glucose cotransporter type 2 inhibitor. This work aims to develop a new
validated sensitive RP-HPLC coupled with a mass detector method for the determination of dapagliflozin, its
alpha isomer, and starting material in the presence of dapagliflozin major degradation products and an internal
standard (empagliflozin). The separation was achieved on BDS Hypersil column (length of 250mm, internal
diameter of 4.6 mm and 5-μm particle size) at a temperature of 35℃. Water and acetonitrile were used as
mobile phase A and B by gradient mode at a flow rate of 1 mL/min. A wavelength of 224nm was selected to
perform detection using a photo diode array detector. The method met the
This study aims to identify the degree of students of Princess Rahma University College owning e-learning skills related to MOODLE as they perceived in the of light Corona crisis. The researchers' questionnaire consisted of (37) items, distributed in three areas of e-learning skills related to the MOODLE on (147) students were chosen randomly. The results of the study showed that the degree of students 'possession of e-learning skills related to the MOODLE was significant. The results also revealed that there were statistically significant differences in the degree of students' possession of electronic learning skills related to the MOODLE due to sex in favor of females. Finally, there were no statistically significant differences in the
