Analytical Study of Mathematics Textbooks in the Basic Education Stage in the Sultanate of Oman According to NCTM Standards
...Show More Authors

The present study aimed to identify the availability of the National Council of Teachers of Mathematics (NCTM) standards in the content of mathematics textbooks at the basic education stage in the Sultanate of Oman. The study used the descriptive-analytical approach, adopting the method of content analysis through using a content analysis tool that included (43) indicators distributed on the four NCTM standards related to the field of geometry, after verifying their validity and reliability. The study population consisted of mathematics textbooks (first and second semesters) for ninth-grade students in the Sultanate of Oman in the academic year 2018/2019, while the sample consisted of Geometry units in the content of those books, which are (5) units in the two semesters. The researchers used specific and accurate procedures during the analysis process, by relying on the topic as a unit of analysis, the paragraph as a unit for recording, the criteria and indicators as categories for analysis, and then calculating the frequencies and percentages of the number of times the indicators were included in the content of those books. The findings of the study revealed that the percentage of including NCTM standards and indicators in the content of the mathematics books for the ninth grade in the Sultanate of Oman was weak with regard to some indicators and very weak and non-existent with respect to most indicators. Therefore, the study recommended the need to develop the mathematics curriculum in the Sultanate of Oman, especially textbooks, taking into account international standards in mathematics education, as well as the philosophy and aspirations of Omani society.

     Peaceful coexistence is not seen as a new topic of secretions of modern civilization, a requirement to solve the problems of our era or one of the indications of urgent immediate needs, rather, tolerance is considered basis for building a state. Therefore, we can touch on the principles and basics of tolerance in the Holy Qur’an, the speeches of the Messenger (may God bless him and grant him peace) and his hadiths, and the principle of brotherhood that he established

Supply Chain Management (SCM) attempts to a create a synchronization of the firm’s processes and those of the supplier to match the flow of materials, services, and information with the customer demand. Due to its importance, the SCM has become inevitable to modern companies. Therefore this research work has been conducted to set a theoretical and applied basis to assist the 1 AYAR factory in adopting the Electronic Supply Chain (e-SC).  To accomplish that the searchers applied many tools such as: quantitative and qualitative analysis, process analysis, Visual Basic software, Monte Carlo Simulation to simulation the designed supply chain to compare its performance against the actual performance of the current supply chain

Direct Method for Variational Problems Using Boubaker Wavelets
...Show More Authors

The wavelets have many applications in engineering and the sciences, especially mathematics. Recently, in 2021, the wavelet Boubaker (WB) polynomials were used for the first time to study their properties and applications in detail. They were also utilized for solving the Lane-Emden equation. The aim of this paper is to show the truncated Wavelet Boubaker polynomials for solving variation problems. In this research, the direct method using wavelets Boubaker was presented for solving variational problems. The method reduces the problem into a set of linear algebraic equations. The fundamental idea of this method for solving variation problems is to convert the problem of a function into one that involves a finite number of variables. Diff
