An open dataset of 505 documented math misconceptions from 31 Turkish studies (11 theses + 20 papers, 2006–2026) on the LGS middle-school exam. 24 fields, CC BY 4.0 licensed. Useful for teachers and researchers comparing commonly reported misconceptions across sources in Turkish secondary mathematics education. Full methodology, data sources, and scope limitations are documented on the linked page. This inventory reflects the samples of the studies reviewed — it is not a nationally representative prevalence measure for Turkey.
