The teacher is the dynamic axis in the educational process. An effective teacher is a source of inspiration and has an effective and positive impact on students learning. Students rely on teachers to make decisions about their studies, work, and living in the future. This study aimed to investigate the degree of how much teachers carry out their professional roles and the affecting factors from the point of view of Zarqa Governorate's teachers. To achieve these goals, researchers created a questionnaire that measures the degree of teachers doing their professional roles and another questionnaire that measures teachers' estimations for the most important affecting factors on carrying out the professional role. The study's sample consisted of (1200) teachers from public schools in Zarqa Governorate's education directorates. This study was conducted during academic year 2018-2019. The study results showed that the percentage of teachers doing their professional role in Zarqa Governorate's education directorates were high, there are no statistically significant differences for the degree of teachers doing their professional roles according to sex, educational qualification, level and years of experience. The researchers recommend to focus on highlighting teacher's role during teaching through the curricula and focusing on field exercise for future teachers.

This case is unique in which the patient had two previous lumbar spinal surgeries, recurrent herniated discs, and new bulged and herniated discs were developed. We aimed to investigate whether implementing the McKenzie method would reduce the symptoms of a long history of Low Back Pain (LBP) with multiple surgeries. A 2-months of McKenzie-type exercise program was performed at a rate of 5 days/week. Disability index, pain intensity, lumbar Range of Motion (ROM), and lower limb strength were tested before and after the exercise treatment intervention. Disability and pain were also measured at 3-months follow-up. The Oswestry disability index and pain visual analogue scale score reduced immediately after the treatment intervention and remained reduced at 3-months follow-up from 44% to 22%, and from 8 to 4, respectively. Lumbar ROM improved about 1.5 cm during standing flexion and 3 cm during extension. Unilateral leg extension of the affected leg and bilateral leg press increased by 16.5 kg and 70 kg, respectively. The current protocol has shown that Mckenzie-type exercise treatment can improve the physical functions and reduce pain in a patient with a history of lumbar spine surgeries and prolonged LBP. In addition, despite no additional exercise, McKenzie method increased the lower limb strength, possibly through nerve root decompression.
