AU - التميمي، يوسف فاضل علوان AU - الخفاجي، ضياء حيدر جبار AB - This current search aimed to acquaintance of effect of Chemistry teaching by educational sample ( Gordon) to acquisition of students of intermediate first class for operations of science . For checking from the search aim ,the two researchers put a hypothesis of zero , its content : there is no difference has statistically significant between the average grade students of trial group , who teach according to educational sample ( Gordon) , and the average grade students of control group , who teach by normal method at level ( 0,05) in choosing the acquisition of operations of science . The current research community specified by the students mail of first grade on intermediate school in Al-Nahdha intermediate school for boys for the academic year (2013-2014) amounting (183 students ) distributed on for classes ( a, b, c, d )using the experimental and control groups , one control the other restraint partially with post-test to measure achievement , the processes of science randomly on the four classes (a, b , c , d) the appointment of random selected Divisions (c , d) two sets of search , as randomly assigned (c ) to be a control group , and (d ) an experimental group. After set aside the failures the stududents number at the two groups (85) demanded by (43) students of the experimental group and 42 students for the control group , rewarded groups in the variables (intelligence, previous information , former educational achievements, the pre- test for science operations), the scientific material identified by the first three chapters of the chemistry book second edition for the academic year 2010 , applied experience in the first semester of the academic year ( 2013- 2014) and the researcher taught the two sets of research by himself and prepared lesson plans necessary which was (24) plan the experimental group , and the same for the control group, The tools of the research include test to measure the basic chemical procedures consisted of (30) objective items of multaple choicestest representing (observation, measurement, classification, inference , prediction, communication ), they were verified of its veracity, stability and the coefficient of difficulty, and showed the results of research using (Z-test) for two independent samples which was equal size to the following : The superiority of the experimental group who studied according to Gordon on the learning control group students who studied according to the usual way to test the acquisition of knowledge In light of the results has been reached a number of conclusions about the teaching model using Gordon, and researcher recommended a set of recommendations and proposals that could benefit teachers and Chemistry teachers , curriculum specialists , as well as the methods of teaching of Chemistry.
