The researcher of this study aims to identify the effectiveness of using cognitive trips viaweb (Web Quest) in teaching Introduction to Mathematics on the mental motivation development among education female students at Afif. The study tool is represented in the design and construction site in the light of cognitive trips tasks strategy "Web Quest" using Dreamweaver program. The author of this paper adopts the reference model (ADDIE) in Web design tasks. The study sample consists of 40 female students, selected to represent the community. The validity of measure is ratified through the validity of internal consistency as the measure is applied on a pilot sample consisting of (28) students, and all the correlations between measure dimensions and scale as a whole are statistically significant at the level of significance (0.01) and this confirms that the measure is highly consistent internally. To ensure the stability of measurements, the two researchers have applied a pilot sample consisting of 28 sophomore female students at the Faculty of Education in Afif. The measurement has been applied on the selected sample twice with 2 week time between the two applications. The internal consistency coefficient Cronbach's alpha of the scale has been measured as a whole as well as for each area of the scale, which expresses the reliability and validity of the scale of construction and the study has the following results: There are statistically significant differences at the level of 0.05 between the mean scores of female students before and after the measurement in the dimensional application to measure mental motivation development (orientation toward learning, solving problems creatively, integration of knowledge, and mental focus) in favor of the grades of students after the measurement, which means the effectiveness of cognitive trips strategy in the development of mental motivation (orientation toward learning, solving problems creatively, integration of knowledge, and mental focus).
