The Current research aims to identify ( The effects of Daniel Model in Cognitive Motivation for the Students of the Third grade average ) , To verify the objective of this research , the researchers added nul hypothesis following : There is no difference is statistically significant at the level of ( 0.05 ) between the average scores of students who studied Daniel Model and the average students who studied by using traditional method in Cognitive Motivation scale. The research was conducted on a sample of the average Third grade students in a medium Al – sadiq Al – Ameen secretary for boys affiliated to the General Directorate for Educational in Baghdad Al – rusafa 2 and for academic year ( 2014 – 2015 ) , the researchers adopted a two Experimental design as research sample ( 55 ) students from the average Third grade students were Selected randomly by the division of A by ( 27 ) students stood to represent the control group , who studied by using traditional method and the Division B by ( 28 ) students groups to represent the Experimental group that studied Daniel Model and rewarded the two groups in the Variables (Students achievement in Physics second grade average, Chronological age in months , intelligence , in Cognitive Motivation ) , and has one of the researchers thought himself by the two groups in two servings per week for each group , was preparing Cognitive Motivation scale including ( 50 ) negative and positive items were verified face validity , by submitting it to a group of specialists , then applied on a prospective sample to calculated the discriminatory power of the item of the scale was calculated construct validity and factor validity have been confirmed persistence of the adoption equation alpha – cronbach reliability coefficient ( 0.89 ) as well as split – half reliability ( 0.83 ) and Test – retest reliability ( 0.90 ). Using simplest t – test with the two ends of the two independent sample were null hypothesis testing yielded results in terms of statistically test. There is a statistically significant difference between the average degree of the experimental group and the control group in the the Cognitive Motivation scale for the experimental group, In the results of researchers sees the need to : 1- A adoption specimen Daniel Mode in teaching physics and included in the curricula and teaching methods course in colleges of education . 2- Conduct similar studies in several stages of study materials and to know their impact on other variables.
