This research aims to examine the effectiveness of a teaching strategy based on the cognitive model of Daniel in the development of achievement and the motivation of learning the school mathematics among the third intermediate grade students in the light of their study of "systems of linear equations”. The research was conducted in the first semester (1439/1440ah), at Saeed Ibn Almosaieb Intermediate School, in Arar, Saudi Arabia. A quasi-experimental design has been used. In addition, a (pre & post) achievement test (20 questions) and a (pre & post) scale of learning motivation to the school mathematics (25 items) have been applied on two groups: a control group (31students), and an experimental group (29 students). The research showed the parity of the two groups in the pretest of the achievement test and the scale of the motivation at the level of significance (α≤0.05). On the other hand, the results indicated that the experimental group exceeded the control group in the posttest of the achievement test and the scale of the motivation with statistically significant differences at the level of significant (α≤0.05) with a high level of impact of the used strategy.
