  • With the advancement in the Internet of things Technology (IoT) cloud computing, billions of physical devices have been interconnected for sharing and collecting data in different applications. Despite many advancements, some latency - specific application in the real world is not feasible due to existing constraints of IoT devices and distance between cloud and IoT devices. In order to address issues of latency sensitive applications, fog computing has been developed that involves the availability of computing and storage resources at the edge of the network near the IoT devices. However, fog computing suffers from many limitations such as heterogeneity, storage capabilities, processing capability, memory limitations etc. Therefore, it requires an adequate task scheduling method for utilizing computing resources optimally at the fog layer. This work presents a comprehensive review of different task scheduling methods in fog computing. It analyses different task scheduling methods developed for a fog computing environment in multiple dimensions and compares them to highlight the advantages and disadvantages of methods. Finally, it presents promising research directions for fellow researchers in the fog computing environment.

  • This study was initially conducted to explore Saudi students' use of reading strategies and their relationship to their reading comprehension level. The study employed quantitative methods to obtain information about Saudi students' perceived use of reading strategies and their comprehension levels. The results showed that EFL learners in Saudi Arabia use planning strategies more than attending strategies and evaluating strategies. Saudi students also perceived the environment as the most critical factor affecting their reading comprehension. There was no significant relationship between Saudi EFL learners' comprehension level and their use of reading strategies. Finally, gender differences favoring female learners were evident in almost all analyses conducted in the current study. Significant differences were found favoring female students in overall strategy use, comprehension level, and the use of evaluating strategies.

  • The present study aimed to investigate the extent to which ordinary classrooms teachers are informed are familiar with Attention Deficit Hyperactivity Disorder 'ADHD'. The researcher adopted the descriptive approach. The sample of the study consisted of (89) male and female teachers who teach students from grade (1) to grade (6) at public primary schools in Northern Mazar Directorate of Education in Jordan. A questionnaire was employed as the primary tool for collecting the data. The findings of the current study indicated an average level of knowledge of ordinary classroom teachers about ADHD. The findings also indicated that there were no statistically significant differences in the extent of ordinary classroom teachers' knowledge of ADHD due to the variables (gender, qualification, professional experience, grade level being taught).

  • There has been a significant growth in global population and industrialization, as a consequence demand for electricity is increasing rapidly and the power systems need to increase the electricity generation. Currently, most of generated electricity is generated from fossil fuels. However, there are many financial and environmental concerns associated with the generation of electricity from such resource. Photovoltaic )PV) solar as a renewable resource is promising. The power output of PV systems is mainly affected by the solar irradiation and ambient temperature. This paper attempts at reducing the burden and improving the accuracy of the extensive simulations related to integrating PV systems into the electrical grid.

  • This study investigated a case of a gifted Saudi student, X, who was early detected through Mawhiba (The Saudi Institution of Gifted) when he was eight years old. Then, the journey continued until he became a Tamayuz member and received a scholarship in 2022 to pursue his bachelor's at one of the prestige, high-ranking universities in the USA to study Mathematics and Economics. Lack of information about the status of Saudi verbal gifted maked X case a model to explore the roles of Mawhiba's programs in supporting Saudi verbal giftedness in general and particularly in learning the English language, plus seeking the opportunities Mawhiba provided for Saudi verbal gifted to enrich their giftedness in the English language through providing extended social networking and finally stating the sample's perspective about the opportunities and services Mawhiba provided him. The three core instruments to accumulate elaboration and interpret qualitative and quantitative data were academic records, writing samples, family observation, and a written interview.

  • The current paper discusses the two most widespread and contradictory educational philosophies of classic German Idealism and modern American pragmatism. Their perspectives of what is truth and what is the best way to distinguish the reasoning idealists from the experienced pragmatists. The implementations of Idealism and pragmatism have affected the education process for several ages and reflect various social changes. The role of schools, educators, environment, teachers, and learners are not the same in both philosophies. However, on reviewing the chronological transmission from Plato's Idealism to Dewey's pragmatism, the resemblances and differences are elaborated here with examples. Furthermore, how these philosophies helped founding advocators for perennialism, essentialism, progressivism, and reconstructionism.

  • The article reviews the quality of information on the Internet in general and health information in particular, where the accumulation and steady increase of information available on the Internet, without concern for its quality or importance, and regardless of the target audience, in addition to the lack of evidence of its credibility such as the availability of the name of the editor and references, and the availability of the name of an academic or research body responsible for that information. Add to this the lack of bibliographic data that can help infer the novelty of the information, and verify the element of trust in it . The problem is exacerbated with regard to the health information available on the Internet, due to its danger resulting from the presence of false health information that may cause danger to human health if relied upon. Through this article, the researcher proposes criteria that can help users search for information to measure the degree of quality, trust, and credibility of information in general and health information available on the Internet in particular.

  • The purpose of this study is to introduce a proposed Framework for Evaluating the Return on Investment (ROI) of E-Learning Programs at Saudi Universities. To achieve this goal, the descriptive analysis methodology is used to analyze the literature review about e-learning and its evaluation from different viewpoints, especially from the ROI-related perspective. As well as the literature reviews related to ROI and the methods of calculating it inside society institutes. This study suggests a conceptual framework for evaluating the ROI of E-Learning Programs at Saudi Universities. This framework is based on the merging process among the analyze, design, develop, implement, and evaluate (ADDIE) model for designing e-learning programs, which gives detailed procedures for executing the program, several evaluating models for e-learning, and the Kirkpatrick model for evaluating the ROI of e-learning. It consists of seven stages (analysis, calculating the costs, design, development, implementation, calculation of the benefits, and calculation of the final ROI).
