摘要:AbstractThe aim of this correlational case study is to examine the environmental factors which affect Level Assessment Exam (a kind of summative evaluation for selection and placement of students in secondary education institutions) scores of the eighth year students, attending primary schools in Melekli, Igdır, Turkey. To achieve this aim, it tries to examine whether economic support factor, private tutoring centre (dershane) support factor, school support factor, family support factor, and private teacher (one-to-one instruction by a privately-paid tutor) support factor predict Level Assessment Exam achievement. A questionnaire was developed by the researchers so as to determine the degree of effect of the aforementioned factors. The questionnaire was administered to thirty-six male and forty-six female eight year students attending three primary schools in Melekli. Multiple Regression Analyses were employed to determine significant predictors of the Level Assessment Exam. The findings of the study indicated that private tutoring centre and private teacher support factors were the significant predictors of the Level Assessment Exam whereas economic, school, and family support factors were not found to be significant predictors of it. Although the results of this small-scale study have certain limitations due to the limited number of data sources and participants, they have important implications in terms of curriculum development since national or international summative exams play important roles in the Turkish context.
