Effectiveness of Blended Teaching Strategy on the Achievement of Third Grade Students in Mathematics

The study aimed to investigate the Blended Education strategy in the achievement of the third grade students in mathematics. The study sample consisted of (97) male and female students distributed on four classes: (47) male and female students in the experimental group and (50) male and female students in the control group. To achieve the objectives of the study, an achievement test was applied after making sure of its validity and reliability. To process statistical data, means, standard deviations, and covariant analysis were used. The study showed the following results: there is a statistical difference on items of achievement test for third grade students in mathematics combined between the performances of the members of the two groups in favor of the experimental group who were taught using the (Blended Education strategy). There is no significant difference at (a=0,05 ) between the two means of performance of members of the study groups on items of the achievement test of third grade students in mathematics due to sex variable. The results of the study also showed that there is no significant differences at (a=0,05) between the means of the performance of members of the study groups on paragraphs achievement test for third grade students in mathematics all together due to bilateral interaction between the two variables: teaching strategy, (traditional and Blended) and sex (male, female). Keywords: (Blended Education, Mathematics, achievement, primary third grade

Exploring Engineering Club

Exploring Engineering Club provides an introduction to a variety of engineering problems and piques the students’ interest in engineering by accompanying the information with hands-on problem solving activities mainly related to structural engineering. The activities will often be done in teams which will teach good teamwork skills, as well as problem solving and critical thinking

Software Performance Analysis

The key to speeding up applications is often understanding where the elapsed time is spent, and why. This document reviews in depth the full array of performance analysis tools and techniques available on Linux for this task, from the traditional tools like gcov and gprof, to the more advanced tools still under development like oprofile and the Linux Trace Toolkit. The focus is more on the underlying data collection and processing algorithms, and their overhead and precision, than on the cosmetic details of the graphical user interface frontends

Antibacterial Activity of Novel Prodrugs of Amoxicillin and Cephalexin

Two novel prodrugs of amoxicillin and cephalexin (amoxicillin ProD 1 and cephalexin ProD 1, respectively) were designed and synthesized to improve the stability and bitter sensation of their parent drugs. The in vitro susceptibility for both prodrugs was determined against Escherichia coli, staphylococcus epidermidis, staphylococcus aureus, Klebsiella pneumonia, streptococcus group A and streptococcus group B, and was compared to that of their active parent drugs.The antibacterial screening demonstrates that amoxicillin ProD 1 and cephalexin ProD 1 were found to be active and are considered among a small number of prodrugs that have therapeutic activity themselves before undergoing interconversion via enzymatic or chemical reaction to their corresponding active parent drugs. Both prodrugs exhibit their antibacterial activity against different types of bacterial strains due to the presence of β- lactam ring in their structures. In addition, it is expected that these novel prodrugs will be much more stable in aqueous media than their corresponding active parent drugs due to the fact that the chemically sensitive amine group contained in the active parent drug structures is replaced with an amide, more chemically stable group, in the corresponding prodrugs

First record of Holothuria (Metriatyla) scabra Jaeger, 1833 (Echinodermata: Holothuroidea) from the coastal waters of the United Arab Emirates

The presence of an endangered and economically valuable species of sea cucumber, Holothuria (Metriatyla) scabra Jaeger, 1833, was investigated in the Alqurm Wa Lehhfaiiah Protected Area near the city of Kalba in the Emirate of Sharjah. Sea cucumber specimens were collected, and identification was first conducted using morphological keys. H. scabra identification was confirmed through microscopic observation of ossicles. Though this species is known to occur in other regions along the Gulf of Oman, this paper represents the first published record of H. scabra, in the coastal waters of the United Arab Emirates
