Over the past three or more decades, many studies have been written about teacher education and the
preparation of science teachers. Presented study is one of which investigated the effectiveness of
scientific process skills on pre-service science teachers of Pamukkale University Primary Science
Teacher Education Program for four years. This study uses a simple descriptive survey approach which
is one-shot survey for the purpose of describing the effectiveness of science teacher education
program on scientific process skills of pre-service science teachers. The participants of the study
consist of 186 primary science pre-service teachers in total from four different semesters of their
teacher preparation program. Test of Integrated Process Skills II (TIPS II) was utilized to collect data.
The data were analyzed using primarily multivariate statistical methods. One way ANOVA was used to
identify patterns within cohorts regarding pre-service teachers’ scientific process skills. Major findings
indicated that Pamukkale University- Science Teacher Education Program helps to develop pre-service
science teachers’ scientific process skills effectively. Especially, science teacher education program
affected pre-service science teachers’ scientific process skills positively in the third and fourth grade.
Key words: Scientific process skill, teacher education program, pre-service science teachers, science
education, constructivist teaching.
