A1 الساعدي، يوسف فالح محمد A2 العاني، رشا طه شحاذة AB The present study aims at identifying the effect of teaching by associations strategy in achievement for the second-grade intermediate female students in Biology. To the purpose of achieve the target of research the following zero hypothesis are set: " There is no significant difference on (0,05) level between the mean scores of the experimental group who taught according to the associations strategy and the mean scores of the control group who taught according to the conventional method in the achievement test of Biology". The present study is limited to the first-grade intermediate female students in one of the Education Directorate, Al-Russafa the first Secondary school for girls, two sections were selected randomly , the final number of the sample taken from the whole population after excluding some of the subjects is ( 72 ) , (36) of them are chosen to be the experimental group who taught according to the associations strategy and (36) of them are chosen to be the control one who taught according to the conventional method. The two groups were equalized with some variables that might affect the independent variable (intelligence, previous knowledge in Biology, pre-achievement in Biology for first grade) and the researcher herself taught both the experimental and the control ones. The researcher made an achievement test consisted of (40) items of multiple choice according to a testing plan that measures the three levels. At the final administration of the test the data were treated statistically by using ( t-test for two independent samples, difficulty factor, discrimination power, wrong alternatives factor) By using the ( K .R.-20), the reliability of the test reached to ( 0,89) The researcher used the following statistical tools in data treatment: The results showed that the achievement of the experimental group who taught according to the associations strategy is higher than the achievement of the control one who taught according to the conventional method , so the two hypotheses were rejected . In the light of the results, the researcher has recommended with some recommendations and suggestions that could be used by the teachers of sciences, biology and even those who are specialized in curriculum and methods of teaching sciences.
