Security is one of the major challenges that affect the deployment of the biosensors that form WBSNs. The implementation of any security protocol comes along with the additional overhead of an extra power consumption from the limited resources of devices like biosensors. Nevertheless, the additional security operations may come with a delay that affects the realtime objective of the biosensors application. In this paper, a lightweight security protocol is presented to secure the medical information which is transmitted from the biosensor to the gateway. The proposed security protocol relies on a counter method at the biosensor side to save the biosensor's power. The security protocol shouldn't include unnecessary computational processes to has an acceptable cost of computational delay. Therefore, the performance of the proposed protocol is compared with that of other existing techniques.
With the wide spread of smart phones, the paradigm of crowd sensing is gaining immense popularity. Crowd sensing is the act of collecting certain kind of data from people in a specific area of interest. Since the users involved in this activity incur a cost for performing the task, i.e. the cost of uploading the data or the energy to sense, they need to be compensated for their work or else they will not be inclined to participate in the sensing task. Many papers have been published related to user selection and incentive mechanisms in crowd sensing. In this paper we review a range of approaches proposed in both areas, provide comparison between them and outline areas for future work.
This paper focuses on discussing the challenges faced in summarizing Arabic documents and the literature in this field, which is fairly limited and very recent. The reviewed systems are classified based on the methodology followed in building the system. Finally, a new system architecture is proposed and discussed. The system relies on the extracting nouns and clustering them based on their semantic.

This study was exploratory survey design in which an attempt was made to explore student understanding of scientific graphs. A Graphical Literacy Test was developed for this study to evaluate the student ability to interpret, and construct graphical information. 125 grade10th science students participated in the present study. Sixty-two of them were female and the rest (63) were male students. Out of the sample, 95 of the students were from public schools. Based on the findings reported in the present study, different educational implications for curriculum planners and developers, science teachers, and students in relation to graphical literacy development.
The study is conducted to explore students' attitudes towards SCL through the blended model in ESL classes. The study was conducted in a training center in UAE and the sample comprised of 34 students. The students were given a survey after attending a general English course (level 8) that lasted for 6 weeks. The survey included general questions about the model used in the classroom and their preference as attendees for this class. The students' age group was 29-35 with mean=31.1. Three students from the sample were also interviewed to get in-depth data about what they liked or disliked. After the data analysis, the survey and the interview showed a general trend of satisfaction among students. However, some of them reported that they felt socially isolated when they interacted with the LMS only. In general the students liked SCL through the blended model and reported that active learning took place in their classes.
UAE vision 2021 emphasize the importance of integrating STEM in higher education as well as developing the required material for developing creativity. Moreover, HCT is an applied higher education institute and its strategic goals focused on developing creativity. So, there is a need to develop a model example for integrating STEM in higher education to convert mathematics from an abstract subject to applied subject as well as developing creative thinking skills.Thus, the main purpose of the study is to analyze the effectiveness of using STEM project-based learning approach in teaching Mathematics to develop creative thinking skills for engineering students at higher education in UAE. The existing procedures for the STEM project-based learning were identified through a literature review. A quasi-experimental design was employed in the study for the quantitative aspect. This study used three groups; two experimental groups and one control group. The experimental group 1 will taught using STEM project-based learning approach where students used the engineering design to create a prototype. The experimental group 2 will taught using STeM project-based learning where students will use a simulation software to create the project. to conclude the approaches impact on the development of creative thinking skills. Whereas, the control group was taught by using traditional methods. Thus, two dependent variables were measured simultaneously for all three groups by the pre-test and posttests at two different times before and after the intervention. This study involved an intervention of the utilization of the STEM project-based learning approach for 16 weeks as follows: 1. Pre-tests of (creative thinking test, and students' beliefs about the unity of knowledge survey) were administered to the three groups during the first week before the intervention; 2. Intervention utilizing the STEM and STeM project-based learning approach for the experimental groups was for 16 weeks. On the other hand, the control group was taught following the traditional method; and 3. Post-tests of (creative thinking test, and students' beliefs about the unity of knowledge survey) were administered to the three groups during the week after the intervention. The independent variable was the method of instruction, either the STEM project-based learning, STeM projectbased learning, or traditional method. The dependent variables were performance in creative thinking skills. A test for creative thinking skills was developed to measure the respective dependent variable. After the four months intervention, the researcher will use the multivariate analysis of variance (MANOVA) to analyze the creative thinking skills test results.
Inquiry-based learning in education represents the student-centred approach that focuses on encouraging learners to construct new knowledge. The main purpose of this study is to explain grade eight-science teachers' and students' perceptions about applying inquiry-based learning in a private school in Dubai. Furthermore, to explore the extent to which the science textbook of grade eight promotes inquiry instruction. Data is collected through a mixed method approach where two science teachers and fifty students in grade eight are recruited to respond to the given questionnaires. Moreover, an evaluation rubric is used to analyse the science textbook of grade eight to explore the extent to which it supports the inquiry practices. The study found that science teachers have positive perceptions toward applying inquiry instruction, although they are not able to differentiate the types of inquiry used in their classes. Besides, students have expressed a positive feeling towards learning science through inquiry-based strategy. In addition, the new science textbook enhances all the inquiry areas and illustrates its components effectively.
The textbook and instructional questions were analyzed using the Revised Bloom's Taxonomy to ascertain the type of cognitive process and knowledge that is being taught in a Grade 6 Science curriculum in a private international school in Dubai, U.A.E. Questions play an important role in critical and creative thinking and it is important to investigate the levels of questions used in the textbook and during instruction. The research used a qualitative approach analysis of the questions, using the Revised Bloom's Taxonomy cognitive and knowledge dimensions. The results showed that lower rather than higher order thinking questions are more common in textbooks and instructions. Textbook questions emphasized "Remember", while instructional questions emphasized "Understand" cognitive process. The most common knowledge dimension is the "Conceptual" knowledge. Therefore, it is recommended that textbook writers and educators include higher order questions within curriculum and pedagogy to help improve critical thinking among learners.
The purpose of this study was to determine the relationship between intensive teachers' training and students' achievement in the Programmed for International Student Assessment (PISA) in the emirate of Abu Dhabi. This study made use of a quasi-experimental design to investigate the effect of teachers? training on students' achievement. All relevant teachers (Science, Mathematics, Arabic and English) have received appropriate training on PISA test skills by qualified instructors. The training was providing intensive workshops for five continuous hours and three times in two months. During these periods, teachers trained the students on the PISA test skills. The sample of the study were students in the secondary schools of the Emirate of Abu Dhabi born in 2002, as well as all teachers who received PISA training.
National Identity is a fluid concept that is subject to reformation. The national Identity in the Arab world can be used as a political tool to Counter-terrorism. However, there is a confusion of national identity especially between the notion of national identity based on citizenship, and the notion of national identity in terms of religion. Therefore, governments should develop strong mechanisms to empower the sense of belonging to the nation in terms of state, rather than religion. In this paper I will highlight some historical examples that would reflect the role played by developing the sense of national identity to counter the religion dominance and a recent example adopted by UAE to empower and create of national identity through education of the youth, as well as the role of awareness through multiple channels such as media to further educate citizens.
