ABSTRACT : Current research aimed to construct an e-tutor accord-ing to Dynamic Math Intelligent Tutoring System (MD_ITS)  to help mathematics teachers to develop their e-courses, and their Knowledge Base according to e-tutor algorithm  and instructional design. A sample of teachers from Taha  Hussein Language school, Yarmouk School, Mohammad  Najibullah experimental language schools were chosen,  The sample is divided into two equal groups: the first  experimental group was taught Math Fractions units to  fourth grade students of primary schools through the  proposed e-tutor software designed in accordance with  the intelligent tutoring system (MD_ITS), and the other  experimental group was taught by the traditional software  prepared by the Ministry of Education. Then the test mea-surements of Math teachers attitudes towards e-courses  depended on ITS were applied. The proposed intelligent  (MD_ITS) design, depended on some instructional mod-els. Researcher adopted the model of the « Fogan Tai,  1994» including phases of: analysis phase, instructional  design phase, Interaction design phase, production phase.  Also addressed the study of the (Rezzaq, 2003) to design a  system, based on smart dialogue, to improve the level of  student performance as a tool to provide conten
