Authors : Khuzaie R. F , Tala H. sasa , Tasneem. I. Al Ayed , Amane Istaiti , Noha Alzubaidi
Abstract : Approximately all universities in Jordan now administer online exams. The results of these tests feed into accountability systems. We examine the degree of satisfaction for online testing. Crucial to the study design is the fact that the university students vary in the level of education, age, Faculties and GPA. In most cases of our study, we find that students in favor of online exam. They find the online exam suitable for all stages, easier than paper-pencil tests, they prefer circulating online exams instead of paperpencil tests, time required to perform online exams is less than that for paper-pencil tests, and hence, preferable for future testing. There was somewhat less consistency in reliability of online exams compared to paper-pencil tests, participants find that online exams don’t reflect true level of examiners, suitability for all subjects. Participants find online exams have many disadvantages and increase stress of examiners.

Authors : Tala H. Sasa1 , Tasneem I. Al Aiayed2 , Noor Al-Alawneh3 , Omniya Rajih Miri4
Abstract : Cooperative learning is an educational approach which is a highly recommended instructional procedure. This study examined the effect of cooperative learning on students’ achievement in the unit of Fractions in Mathematics for Fourth Grade. For this purpose, two samples were taken (each consisted of 46 students) the first one from Jaba Girls Basic School in Palestine, and the other one from Mobes Girl School in Jordan. Each one of them was divided into two groups: an experimental group and a control group, cooperative learning was applied to the experimental group and the control group was taught by teacher-centered teaching. The students’ achievement was measured by a researcher-designed achievement test given to students as a pretest and a posttest. Analysis of the achievement test scores responses revealed that cooperative learning strategy have significantly more positive effects on students’ achievement than teacher-centered teaching method. These results provide an evidential base for educational authorities to implement cooperative learning methods and encourage and persuade teachers to implement these methods in the two countries mentioned before.

Financial Obstacles and Disadvantages of E-Learning From The Viewpoint of Dammam Teachers,
Authors : • Mayada Abu Alhomos • Nawal.H.Bahtiti • Tasneem Alayed • Omniya Miri
Abstract : The efforts of containing the novel virus (COVID-19) have begun to show signs of psychological impact on teachers and students across the globe. As a result of the COVID-19 pandemic, many school districts have closed for the remainder of the academic year. These closures are unfortunate because, for many students, schools are their only source of trauma-informed care and supports. When schools reopen, they must develop a comprehensive plan to meet their students’ the potential mental health needs as social distancing and awareness campaigns can be a double-edged sword, if handled inadequately. This paper evaluated the challenges of teachers in Dammam in e-learning during the period of the new coronavirus (COVID-19) global pandemic.

Abstract : The study illustrates the impact of barium oxide (BaO) on structural, physical, optical, and radiation shielding features of a series of multi-component of barium-containing borate-based glasses, namely Sodium Zinc Borate Glass. The amorphous nature of each glass material was confirmed by X-ray diffraction (XRD) analysis. Fourier-Transform-Infrared (FTIR) was used to identify the BO3-BO4 distribution and how the variation of Ba-concentrations affects this distribution. The results show that the increase of barium content increases the density of glasses and, in turn, reduces their bandgap. The investigation of the shielding properties at different energies (0.01-10 MeV) by Phy-X program indicates that the high-density of Ba-30 exhibited the best performance in terms of attenuation factor. On the other hand, the samples Ba-0 and Ba-15 show the highest durability results (lowest dissolving rate). These outcomes indicate that the glass samples exhibited promising radiation shielding properties for different applications.

The Impact of TeO2 on Physical, structural, optical and radiation shielding features for borate glass samples
Authors : M.H.A. Mhareb; Ragad Alsharhan; M.I. Sayyed; Y.S.M. Alajerami; Muna Alqahtani; Tasneem Alayed
Abstract : This research aims to discover the impact of the tellurium oxide on structural, physical, and optical properties of borate glass samples modified with BaO and MoO3. The amorphous nature of each glass sample was proven by X-ray diffraction (XRD) analysis. Fourier transform infrared (FTIR) was utilized to recognize the functional groups for TeO2 and B2O3. The results exhibited that the rise of TeO2 ratio raises the density of glasses and decreases their bandgap. On the other hand, the samples BTM3 show the highest durability results. The current glass samples exhibited stable glasses properties that can be used for different applications. Moreover, we studied the radiation shielding features for the fabricated glasses by determining the mass attenuation coefficient (MAC) and other related factors. We discussed the effect of both B2O3 and TeO2 on the attenuation performance of the fabricated specimens. The MAC results showed that when we replace the B2O3 with TeO2, the MAC increases, which means that the TeO2 leads to enhancement in the shielding competence of these glasses. At 15 keV, the MAC is 22.39 cm2/g for the free TeO2 sample, while it is increased to 42.15 cm2/g for the glass with 70 mol% of TeO2. Also, when the density changes from 3.4446 to 5.5057 g/cm3, the LAC enhances and changes from 77.14 to 232.05 cm-1 at 15 keV, from 16.81 to 51.81 cm-1 at 50 keV, from 0.309 to 0.511 cm-1 at 0.5 MeV and from 0.096 to 0.211 cm-1 at 15 MeV.
