3. Method
In the study, in order to determine if the teaching made in accordance with the Project-Based Learning Method
and the one made in accordance with the current program had different effects on students’ success, the
experimental method with pretest-posttest control group.
The population of the study is composed of all the 6th graders in the province of Bursa. The sample of the study
is composed of a total of 92 students studying at two different elementary schools. That the success levels of the
experimental and control groups selected from both schools for the subject of science and technology were close to
one another was determined as a result of the pre-tests made. With the experimental and control group students at
both schools, 4 lesson hours were spent for the first part acquisitions and 6 lesson hours were spent for the second
part acquisitions. To measure the students’ success levels, two identical “Electric in our Life Achievement Tests”
were administered in pre-test and post-test sessions.
There are totally eighteen student acquisitions in the ‘Electric in our Life’ unit. An achievement test of 40 items
including all the acquisitions was prepared. The measurement tool was determined as a multiple-choice test with
four alternatives. The achievement test prepared was administered to 60 7th grade students. The KR- 20 reliability
coefficient of the test was calculated as 0,89 and the mean difficulty was found as 0, 58. According to the results
obtained in the item analysis, the 32nd item was rearranged with the aim of testing all the acquisitions and two tests
of 20 items were prepared to be administered in the pretest and post-test sessions. The experimental and control
group students at two separate schools were administered the pre-test one week before the time determined
according to the annual curriculum for the ‘Electric in our Life’ unit. The unit was finished in ten lesson hours in the
experimental and control groups and after that the post-tests were applied.
To examine the effectiveness of the teaching made with the Project-Based Learning Method, the
experimental and control group students were administered the “Electric in our Life Unit Achievement Test” applied
in pre-test and post-test and results were obtained by applying t-test and ANCOVA to the data.
