In the current study, the purpose is to determine the secondary school students’ cognitive structure related to the concept of atom by using the drawing technique. The study was conducted with the participation of 90 5 th , 6 th , 7 th and 8 th grade students in 2016-2017 school year. The students were asked two open-ended questions to illustrate the concept of atom in their minds and to explain where they have learned the information expressed in their drawings about the atom so that the atom models in their minds could be elicited. The students’ responses to these questions were categorized by means of qualitative analysis and frequencies were calculated for them. At the end of the study, it was determined whether the atom models drawn by the students are false or acceptable. It was seen that the students rarely illustrated nucleus and electrons in their drawings and they usually drew spheres. Moreover, the students stated that they learned this information mostly from different textbooks or the Internet. Extended English summary is in the end of  Full Text  PDF (TURKISH)  file . Ozet Cocuklar, etraflarinda olan olaylara karsi asiri meraklidirlar ve kavramlara kendileri kisisel anlamlar yuklemektedir. Ogrencilerin kavramlari anlayabilmeleri icin kavramlarin zihinlerine dogru bir sekilde kodlanmasi gerekmektedir. Bu calismada; ortaokul ogrencilerinin atom kavrami ile ilgili bilissel yapilarinin cizim teknigi ile belirlemesi amaclanmistir. 2016-2017 egitim ogretim yili bahar doneminde gerceklestirilen calisma; 5., 6., 7. ve 8. siniflarinda  ogrenim gormekte olan toplam 90 ortaokul ogrencisiyle gerceklestirilmistir. Calismada ogrencilerin zihinlerindeki atom modellerini belirlemek amaciyla atom kavrami ile ilgili bir cizim yapmalari ve bu cizdikleri sekle ait bilgiyi nereden ogrendiklerini ifade edebilmeleri icin iki adet acik uclu soru sorulmustur. Ogrencilerin verdikleri cevaplar nitel analiz yontemiyle kategorilere ayrilmis ve frekans degerleri elde edilmistir. Arastirma sonucunda ogrencilerin cizdikleri atom modellerinin yanlis veya kabul edilebilir seviye oldugu belirlenmistir. Ogrencilerin cizimlerinde nadiren cekirdek ve elektronlara yer verdigi genellikle kure seklinde cizim yaptiklari gorulmektedir. Ayrica ogrencilerin bu bilgilere genellikle farkli ders kitaplarindan veya internetten ogrendiklerini ifade ettikleri tespit edilmistir.
