The objective of this research is to evaluate the impact of the inductive method in teaching physics as compared to the traditional way. The used sample involves students of the second year of the middle school education from Kouba city (Algiers center) in the 2006/2007 academic year. The population of research consisted of 920 students (males, females). The used research sample, which constituted 144 students (60 males and 84 females), is randomly chosen. This sample is divided in two groups. The experimental group consisted of students (36 males, 36 females), and the test group, (72 students, 48 females, 24 males). The experimental group students studied via the inductive method, but the students of the test group studied via the traditional method of teaching. To achieve the objectives of the research, the following tools are used: 1) A Preliminary questionnaire is distributed to the members of the sample to determine their opinions towards the traditional way of teaching physics. 2) A Preliminary achievement test for the total sample members is distributed. 3) A post test for students of the experimental group. 4) A post experimental questionnaire is distributed to the members of the experimental group to determine their opinions towards the inductive method in teaching physics. The findings of the study show that there are significant statistical difference at the level of 0.05 between the achievement of students who studied physics via inductive method and those who studied physics via the traditional method in favour of the experimental group.
