Abstract
This study aimed at investigating the impact of a problem-solving based program on mathematical problem-solving among 10th-grade students due to the variance of their mathematical self-concept. The purposive sample of this study consisted of (89) male and female students from Wadi Bani Kharous Basic Education School and Om Hakeem Basic Education School at Sultanate of Oman. The sample was divided into an experimental group, which consisted of (48) students, and the control group consisted of (41) students. The instructional materials of Polynomial and Algebraic Functions Unit and Trigonometric Functions Unit for Grade 10th were designed based on the problem-solving program. The problem-solving test and mathematical self-concept scale were developed, and both were valid and reliable. The findings showed that: there were significant statistical differences in the mathematical problem-solving test in favor of the experimental group. The findings indicated that the significant statistical differences in the mathematical problem-solving test are due to the mathematical self-concept and the absence of statistically significant differences in the mathematical problem-solving test is due to the interaction between teaching methods and mathematical self-concept in light of the findings, the study suggested some crucial recommendations including the importance of enriching mathematics curricula with mathematical problem-solving strategies and having professional development workshops to train teachers on how to use mathematical problem-solving strategies and urge them to use these strategies in teaching Mathematics
Highlights
The progress of countries is basically linked to the development of their sciences, especially mathematics. this is because mathematics is an important tool for realizing relationships, organizing ideas, and understanding the surrounding environment
The findings indicated the effectiveness of the proposed program in the development of inference and the formation of mathematical sense among the students
According to the significance of using strategies to solve mathematical problems, this study aimed to examine the effectiveness of a problem-solving program among students in the tenth grade based on the variance of their mathematical self-self
Summary
The progress of countries is basically linked to the development of their sciences, especially mathematics. this is because mathematics is an important tool for realizing relationships, organizing ideas, and understanding the surrounding environment. It is a method of research that develops through the sensory experiences and its application in other sciences. In light of the development of science, there have been changes in mathematics which encompassed a development on all mathematics branches. These developmental changes have become an indispensable fundamental pillar in many social and natural humanities With accordance to the outstanding importance of mathematics science and its pedagogy, it has been given special priority by the educational systems and the international bodies and organizations. The mathematics curriculum has received a great deal of interest included the development and innovation in its content, learning objectives and teaching methods. The purpose of mathematics teaching is developing the learners’ cognitive aspect of knowing the laws, mathematical concepts, theories, postulates, assumptions, the calculations, and developing the human mind, improving students’ ways of sound thinking, and preparing the individuals who are able to employ mathematical knowledge in solving various http://ijasos.ocerintjournals.org 187
