Özet

This article explores the relationship between bilingualism and critical thinking. To investigate this, monolingual and bilingual participants from various public secondary

schools in Germany were invited to take part in the experiment through purposive sampling. Data for this quantitative study were gathered using the Critical Thinking

Disposition Scale (Semerci, 2016), a 49-statement, five-point Likert-type scale. This multidimensional scale assessed the extent to which participants could use metacog-

nition, flexibility, systematicity, tenacity and patience, and open-mindedness to reflect their critical thinking dispositions. When analysing the correlation between bilingualism

and the critical thinking dispositions of the participants, these five subscales were used as a basis. The data were analysed using the SPSS software and an Independent Two

Samples t-test. The critical thinking dispositions of bilingual children were also compared in terms of gender and age. The study's findings showed that bilingual children

seem to have performed better in all five of these critical thinking disposition subscales. According to these findings, it can be concluded that there is a correlation between bi-

lingualism and critical thinking dispositions.
