As an American living in Turkey to produce software systems for the Education industry. It is in my honest opinion this is mostly all false. Evolution was not removed (if I'm correct it was shifted in which years it was taught, pushing it later in the primary education years). Jihadism is not on the agenda at all. But some south-eastern/eastern provinces do place Islam studies on the bill (in historical manners). It's much like how the US has a "Bible belt" in the south where creationism is taught along evolution. Turkey has a "Quran belt" in it's south-eastern border that also places more emphasis in religious teachings along side it's sciences. In the western portions this is essentially non-existent besides the historical context (Ottoman was Islamic after all)
