Abstract: The cotemporary world witnesses currently a rapid change due to the challenges imposed by the information technology in all scientific aspects.Hence, the scientific knowledge has become a prerequisite for each individual in this world. This led to a new view on education, in that it is no longer to be a process of providing information but it is a technique for a better learning.However, the main goal of education has shifted to focus on how to make the student to think appropriately and how to utilize the skills of the scientific thinking in order to motivate their thinking and understanding of knowledge as well as discovering the facts and relationships concerning the scientific phenomena aiming to form the generalities. The problem of the current research is mainly concerned with specifying the classical methods adopted in the Iraqi schools which do not match the contemporary scientific development. This research aims at utilizing the strategy of the strategy of forming generalizations according to Helda Taba Inductive Model as a teaching technique in order to identify its effect on : 1 - achievement in Biology.2 - the skills of the scientific thinking of the Fifth - Year female pupils.For sake of achieving the above two aims, two null hypotheses have been formed as follows : 1 - There are no statistically significant differences at level of significance of 0.05 between the mean scres of the female pupils (the experimental gronp), who have been taught according to the strategy of forming generalizations the strategy of forming generalizations, and the mean scores of those female pupils who have been twght classically in the achievnent test. 2 - there are no statistically siguificant differences at level of significance between the experiemental group, who have been taught according to the strategy of forming generalizations, and the mean scores of those female pupils who have been taught classically in the test of the scienhific thinting skills. In order to verify the above two hypotheses, the researcher has conducted an experiment which lasted for one whole academic semester.This experiment inluded : - The lesson plans. - The scientific thinking skills test (30 items). - An achievement test (60 items).The discrimination and difficulty power as well as the alternative action of the two test have been computed.Moreover, validity and reliability of the two tests have been secured. The reliability of the scientific thinking test has been found out to be (0.75) and the reliability of the achievcment test has been found out to be (0.92). This was done by using koder Richardson formula - 20. The researcher has prepared an experimental design, comprising two groups, the first one of which is called the experimental group which is to be taught according to the strategy of forming generalizations.While the second group is called the control one which is to be taught classically. The sample of the study covers (46) female pupils at the fifth - year secondany school (scienbific branch).The whole sample have been randomly distributed into two groups, the experimental one is of (24)pupils and the control one is of (22)pupils. The equalization between the testees in the variables of age, intelligence, exinformation, previous achivement in Biology and the scientific thinking skills has been conducted. The experiment group was conducted at the second academic semester (7weeks).The researcher himself had taught the two groups.The results obtained has been statistically analyzed by using two - indepenbent samples t - test.The results gained showed a better performance of the experimental group more than that of the control one in the scientific thinking and the achievement tests. In the light of the above results, the researcher reconmends the use of the strategy of forming generalizations in accordance to Helda Taba Inductive Model.Also, the researcher recommends to conduct other studies and research on other subjccts other than Biology on different school stages to find out the impact of the strategy of forming generalizations on thinking skills.
