Sekizinci sınıf öğrencilerinin istatistiksel okuryazarlıklarının bağlam içeren ve içermeyen problemler üzerinden incelenmesi

The aim of the present study was to thoroughly investigate eight grade students' achivement and statistical literacy in statistical literacy problems with and without context. Moreover, the eight grade students' achievement in problems with and without context was compared. The study was conducted in Çankaya and Yenimahalle districts of Ankara in the spring semester of the 2019-2020 academic year. The participants of the study were selected through purposive sampling as 500 eight grade students from four public schools. In the study, both qualitative and quantitative methodologies were used. The data were collected using the Statistical Literacy Test with Context Problems (SLT-CP) and the Statistical Literacy Test without Context Problems (SLT). While qualitative research methodologies were used to determine the achievement of students in statistical content domains and to compare their achievement in problems with and without context, the quantitative research method was used to investigate the statistical literacy of students according to statistical content domains. The students' achievement in the tests and their statistical literacy differed across statistical content domains and the students' common misconceptions and solutions were determined. Additionally, the student responses in open-ended problems were classified under four categories as statistical, pre-statistical, non-statistical and unrelated and the responses were examined in detail. When the students' achievement in statistical literacy problems with and without context was compared in terms of statistical content domains, no significant difference was observed in the achievement of students in the domains of measures of central tendency, graph interpretation and questioning of statistical data. However, a significant mean difference was found in the sampling domain.
