The current research targeted recognizing the effectiveness of teaching the course of 'Manual and Mechanical Embroidery', on rationalizing the consumption of university students. The research was conducted on a sample of (120) students, at the second class of the Household Arts Department at El-Taef University. The sample was selected from different economic and social levels. The study took a period of two months. The research followed the descriptive analytic approach. The data of this research, was gathered through the questionnaire of selecting and purchasing the embroidered pieces, the questionnaire of selecting and making the embroidered pieces, and the questionnaire of rationalizing consumption. To analyze these data, the researcher used repetitions accounting, percentages, Chi-squared test, the degrees of freedom, and Pearson's Correlation Coefficient. The results of the research, were as follows:
There is a negative correlative relationship between the axis of selecting and purchasing the embroidered pieces, and the variable of the father's profession; and there is no relationship with the rest of the variables of the economic and social level of the student.
There is a negative correlative relationship between the axis of selecting and making the embroidered pieces, and the variable of the area of the family's residence, and the variable of the father's profession; and there is no relationship with the rest of the variables of the economic and social level of the student.
There is a negative correlative relationship between the axis of rationalizing the consumption, and the variable of the family's monthly income, and the variable of the father's level of education, and the variable of the father's profession; and there is no relationship with the rest of the variables of the economic and social level of the student.
There is a positive correlative relationship between the axis of selecting and purchasing the embroidered pieces, and the axis of rationalizing the consumption.
There is a positive correlative relationship between the axis of selecting and making the embroidered pieces, and the axis of rationalizing the consumption.
There is a positive correlative relationship between teaching the subject of 'Manual and Mechanical Embroidery' (the first axis + the second axis), and the students' rationalizing of consumption.
