This study aimed to find the effectiveness of the MathCad software in acquiring the concepts of algebraic functions among the tenth grade students and their motivation towards learning mathematics. To verify this, a teacher's guide was prepared for teaching the Unit of Polynomials and Algebraic Functions using MathCAD software. The researcher has also prepared a test to measure the acquisition of the concepts of algebraic functions, and its validity and reliability were checked and verified. The sample of the study consisted of (61) female students of the tenth grade in a basic education school in Muscat Governorate. They were devided into two groups: an experimental group who studied the Unit of Polynomials and Algebraic functions using MathCAD, and a control group who studied the same unit using the usual teaching method. The study found the following results: There is a statically significant difference at the level of significance (a= 0.05) between the mean scores of the experimental group and the mean scores of the control group in the post-application of the test in favor of the experimental group. There is a statically significant difference at the level of significance (a= 0.05) between the mean scores of the experimental group and the mean scores of the control group in the post-application of the motivation scale towards Mathematics in favor of the experimental group. Considering these results, the researcher recommended the necessity of applying and using MathCAD program in teaching the various subjects of algebra in particular, and other Mathematics subjects in general. Baesd on the positive effects the study had shown on the acquisition of the concepts of algebraic functions among the students.
