Abstract EN

The formation and development of scientific concepts to the fifth grade science students one of the objectives of teaching science, and requires this objective approach "fit" that includes the safety of the composition and the acquisition of scientific concepts.

Have affected the modalities and the prevailing traditional methods of teaching in the composition and the acquisition of scientific concepts and absorb the students.

Son confirms many of the researchers and educators interested in teaching concepts, ways of teaching modern concepts of with examples and teaching strategies that give the role "of the students that the exercise of knowledge of the properties of things and attitudes and compare and try to distinguish between them and interpreted in the light of the attributes of scientific information.

Seeks current research to investigate the effect Nmodji (Merrill - Tensson) and the educational side of the collection and the acquisition of chemical concepts to the fifth grade students in the science of chemistry compared to the traditional way Bdlk highlight the research problem as follows 1 - The Alnmadj and modern teaching methods in the teaching of concepts, applications of learning theories 2 - through out the Alnma \ c teaching staff can see growth \ c the best in the acquisition of scientific Alnvahem.

The use of concepts in teaching led researchers to study the most important Alnmadj educational methods and strategies for teaching concepts.

Hence the importance of studying this topic Alnmadj for the purpose of standing on the effectiveness of each of them and know the effect of Nmodji (Merrill - Tensson) and the educational side in the acquisition of scientific concepts Hypotheses 1 - does not have a statistically significant difference DE between the average degree of the first experimental group who studied religion Bnmodj (Merrill - Tensson) educational degrees and the average group Aldabth religion studied in the traditional manner 2 - does not have a statistically significant difference DE between the average degrees of educational About two o'clock studied religion Bnmodj (Gagne) and the average educational degrees ABG studied the control of religion in the traditional manner 3 - does not have a statistically significant difference DE between the average degree of the first experimental group who studied religion Nmodj (Merrill - Tensson) educational degrees and the average second experimental group who studied religion Bnmodj (Gagne) educational Search procedures First ": - Experimental Design The researchers used the selection of experimental design with partial seizure (two experimental and control) with a dimensional check.

May limit the search tool through the identification of scientific material from the book of chemistry were taken chapters 4.5 and 6 have been identified scientific concepts and to targets and formulation of behavior "was prepared lesson plans for the totals of the threebuilding selection Achievement user in measuring the acquisition of scientific concepts for each of the three groups and compared with the way traditional measure used was the honesty virtual rung level and certified construction was measured stability test using the equation (Cooder - Richaruson 20) and the reliability coefficient (0.89) and used statistical methods appropriate, such as analysis of variance and Pearson correlation coefficient and Chi square and coefficient of difficulty and the coefficient of discrimination and effective contrast.
