The Effect of the Flipped Classroom Strategy on Eleventh Grade Students’ Understanding of Physics and Their Attitudes Towards Physics in Tonnb Secondary School in the UAE

This study investigated the impact of employing the flipped classroom strategy in teaching “Laws of Motion“on eleventh grade students’ understanding of physics concepts and their attitudes towards physics. A total of 59 grade eleven students at Tonnb secondary school in UAE participated in the study, (30 in experimental group, and 29 in control group). A pre-post scientific concepts test and attitudes towards physics scale were administrated. The results revealed that there were statistically significant differences between the study groups in favor of students in the experimental group on both study variables. The study recommended the importance of employing flipped classroom strategy in teaching scientific concepts. Keywords: flipped classroom strategy, understanding of physics concepts, attitudes towards physics

A FIXED POINT APPROACH TO STABILITY OF A CUBIC FUNCTIONAL EQUATION IN 2-BANACH SPACES

In this paper, we prove a new type of stability and hyperstability results forthe following cubic functional equationf (2x + y) + f (2x - y) = 2f (x + y) + 2f (x - y) + 12f(x)in 2-Banach spaces using fixed point approach

Matching Subcarrier Resource Allocation and Offloading Decision

A heterogeneous cellular network can define as a network that is composed of different cell sizes (macrocell (MeNB), small cell (SeNB), femtocell). Such heterogeneity of network is the backbone of the 5G networks where new applications on mobile devices need extensive computing power consumption and ultra-low latency constraints. Using a heterogeneous network will provide multiple paths in which the users’ data can flow through the network depending on the users’ available resources, remaining energy, etc. we study the heterogeneous network model, which contains MeNB, SeNB and femtocells. Also, we propose a matching subcarrier resource allocation and offloading decision (MSRAOD) algorithm, that depends on recourse allocation optimization. The main optimization goal has been set to minimize the total energy consumption of mobile users’ devices with acceptable latency requirements of the applications. Our proposed algorithm results show that the proposed algorithm enhances the average energy consumption of mobile users in the heterogeneous network
