AU - المعموري، عصام عبد العزيز محمد عباس AU - الخيلاني، رعد كريم محمد AB - There is an urgent need felt by researchers to improve methods and models and strategies used in teaching physics for grade average, making them thinking about using the cooperative learning is one of the ways in which played a role in changing the misconceptions in the material other than physics, and perhaps contribute to the development of collection and scientific thinking among those students. The current research aims to investigate the effect of the use of cooperative learning method in the collection of second-graders average in physics and scientific thinking. Limited research on a sample of second graders average second semester of the academic year 2009 / 2010 the content includes four chapters of the book physics for grade average. The number of sample subjects (97) students divided into three divisions were selected one at random to represent the experimental group by (33) students have studied according to the method of cooperative learning and accounted for the group second by (32) students in the control group have studied according to the method of regular and after exclusion of students who failed 's (5) students were (3) in the experimental group (2) in the control group, the number of students (60) students spread by (30) students per kit. The two groups were equal in the three variables are age in months and former intelligence and achievement in physics research after completion of requirements in terms of scientific material and to identify behavioral objectives, formulation and preparation of lesson plans. Promising researchers, research tools and are the achievement test in physics as the number of paragraphs (20) a paragraph of no multiple-choice test measure of scientific thinking, where the researchers to adopt a measure prepared by the researcher (Youssef Ahmad Khalil) has been presented to a group of experts was to keep it unchanged consists of a (100) of poverty is divided into five sections (problem identification, choice of hypotheses, testing hypotheses, interpretation, dissemination). They found at the following: there is a statistically significant difference between the degrees of the experimental group which studied according to the model of woods and degrees of pressure group which studied according to the standard way in each of the achievement test and the test of scientific thinking in favor of the experimental group. The papers were a number of recommendations and proposals including the use of this method in the teaching of physics and open training courses for teachers on how to use and application of modern methods of teaching and a comparative study between the method of cooperative learning and other educational methods.
