Its validity and reliability were verified, reaching an overall reliability coefficient of 0.96. The study sample consisted of 170 male and female teachers of secondary teachers in government schools at the Governate of Tulkarem which constitutes 50% of the study population. Results showed high levels in the area of the adequacy of teaching competencies and the area of teaching and learning although the area of assessment was at an average level. Teaching and learning was followed by the adequacy of the teaching competencies followed by assessment respectively. Results also showed a lack of statistically significant differences on all the variables of the study. The most important findings of the study were the lack of a comprehensive system calendar for teachers based on clear criteria, the lack of attention to scientific research, and the lack of interest in contact and communication between teachers and the community. The main recommendations of the study are to develop a strategy for evaluating the educational standards within clear and specific criteria, and encourage scientific research to identify aspects necessary to rehabilitate, support and develop teachers.(Published Abstract) http://search.shamaa.org/abstract_en.gif ID - 126675 OP - ص ص. 621-651 T1 - دور الاشراف التربوي في التنمية المهنية لمعلمي المرحلة الثانوية بالمدارس الحكومية : دراسة ميدانية بمحافظة طولكرم [مقال] UL - 1 http://search.shamaa.org/fulltext.gif http://search.shamaa.org/PDF/Articles/BAJepsc/40JepscVol18No1Y2017/jepsc_2017_v18-n1_621-651.pdf النص الكامل (PDF)
