G2: The control group which the conventional training approach was applied. In the
conventional approach of teaching, the teacher was active. The teacher used explanation method and
pupils listened to him/her. And pupils were asked some questions by the teacher during the process.
During the teaching of science lesson in the “control group” blackboard was only used. Lessons were
taught by solving examples using the blackboard and the pupils were inactive in this approach.
T1: Achievement test about the subject of “Static Electricity” unit of “Electricity Conducting
Our Lives”. Achievement test was used as pre-testing, post testing and retention test. Retention
learning test was applied to experimental and control groups two months later after the application of
post-test.
The groups were chosen at random as the experimental and the control groups. In the
experimental group, the science lesson is traited with the curriculum and the material which were
prepared according to the constructivist learning approach. In the control group, the science lesson is
treated with conventional training approach. The teacher of the experimental group was educated on
how the science education is treated with constructivist learning approach before the application. The
training was carried about by the same teacher in the both groups.
