The Role of School Manager in Encouraging the Teachers to Apply Self-Education Process Among Students in Jordanian Schools

The Jordanian education system is categorized into the pre-primary, primary, secondary or vocational, and tertiary education. In the Jordanian educational system, school managers are bestowed with the primary responsibility of ensuring that the education program is successfully implemented in schools and in enhancing effective teacher-student cooperation. The main objective of this research is based on creating an understanding of the role of school managers in encouraging teachers to apply self-learning process among students in Jordanian school. In this vein, the research adopts a conceptual framework which identifies how an effective teacher interacts with students in classroom setting by elaborating the specific personal and professional characteristics of the teachers that enhance self-learning. Further, the literature review section summaries the findings of other studies relevant to this topic and that supports the conceptual framework adopted in this study. Based on the study objectives, the research question adopted for this research is to establish what roles the school managers play in encouraging teachers to apply self-learning process in Jordanian classes? In line with the findings of the reviewed literature, the study recommends the school managers to provide teachers with training courses to enhance their professional skills and to provide a supportive teaching and learning environment in schools. Keywords: Educational system, self-learning process, teaching, student-centered learning, teacher-student cooperation.

Two new pulsating low-mass pre-white dwarfs or SX Phenix stars?*

Context. The discovery of pulsations in low-mass stars opens an opportunity for probing their interiors and to determine their evolution, by employing the tools of asteroseismology. Aims. We aim to analyze high-speed photometry of SDSSJ145847.02$+$070754.46 and SDSSJ173001.94$+$070600.25 and discover brightness variabilities. In order to locate these stars in the $T_{\rm eff} - \log g$ diagram we fit optical spectra (SDSS) with synthetic non-magnetic spectra derived from model atmospheres. Methods. To carry out this study, we used the photometric data obtained by us for these stars with the 2.15m telescope at CASLEO, Argentina. We analyzed their light curves and we apply the Discrete Fourier Transform to determine the pulsation frequencies. Finally, we compare both stars in the $T_{\rm eff} - \log g$ diagram, with known two pre-white dwarfs, seven pulsating pre-ELM white dwarf stars, $\delta$ Scuti and SX Phe stars. Results. We report the discovery of pulsations in SDSSJ145847.02$+$070754.46 and SDSSJ173001.94$+$070600.25. We determine their effective temperature and surface gravity to be $T_{\rm eff}$ = 7 972 $\pm$ 200 K, $\log g$ = 4.25 $\pm$ 0.5 and $T_{\rm eff}$ = 7 925 $\pm$ 200 K, $\log g$ = 4.25 $\pm$ 0.5, respectively. With these parameters these new pulsating low-mass stars can be identified with either ELM white dwarfs (with ~ 0.17 Mo) or more massive SX Phe stars. We identified pulsation periods of 3 278.7 and 1 633.9 s for SDSSJ145847.02$+$070754.46 and a pulsation period of 3 367.1 s for SDSSJ173001.94$+$070600.25. These two new objects together with those of Maxted et al. (2013, 2014) indicate the possible existence of a new instability domain towards the late stages of evolution of low-mass white dwarf stars, although their identification with SX Phe stars cannot be discarded.Comment: 5 pages, 5 figures, 1 table, accepted for publication in A&A
