THE EFFECT OF (K.U.D) STRATEGY IN THE ACHIEVEMENT IN CHEMISTRY SUBJECT IN SECONDARY SCHOOL SECOND YEAR FEMALE STUDENTS
To achieve the research objective the two researchers, formulate the following zero theorem: There is no significant difference at inference level (0.05) between the experimental female students mean marks who will study according to ((K.U.D)strategy and the marks of of control group female students in the achievement test .The experiment test of partial control (control group and experimental group) .The research sample consisted of (61) female students who were distributed on two groups, control and experimental and the two groups were rewarded according to the following variables (Intelligence test, chronological age in months, previous knowledge test, previous achievement) The two researchers made achievement test that consisted of (40) objective items from multiple choice type by four substitutions. The psychometric characters of items, validity reliability and the results is the effect of (K.U.D) strategy in the achievement of female students in chemistry .In the light of the research results the two researchers introduce many recommendations and suggestions .
