In science education literature, there are many studies that investigated students’ stereotypical images of scientists at all levels (e.g. Cakmakci, Tosun, Turgut, Orenler, Sengul, & Top, 2011; Kaya, Dogan, & Ocal, 2008; McCarthy, 2014; Narayan, Park, Peker, & Suh, 2013; Song & Kim, 1999; Yvonne, 2002; Turkmen, 2008). Why are students’ images about science and scientists important for the science education community? Because, students’ attitudes toward science are essential during their educatio...
Bu calismanin amaci bilimin dogasi alaninda son 10 yilda yapilan calismalari farkli degiskenler acisindan incelemek ve gelecekte yapilacak olan calismalara yol gostermektir. Bu amac dogrultusunda son 10 yilda SSCI/SCI dergilerde yayinlanmis ve basliginda bilimin dogasi terimi gecen 127 makale incelenmistir. Calisma nitel yaklasim ile gerceklestirilmistir ve arastirma yontemi olarak dokuman analizi kullanilmistir. Veriler icerik analizi yontemi ile analiz edilmistir. Icerik analizi gerceklestiril...
The aim of this case study was to examine pre-service science teachers’ (PSTs) perceptions of their Technological Pedagogical Content Knowledge (TPACK) development after creating digital stories based on science topics drawn from the national curriculum. A total of 21 PSTs enrolled in Introduction to Computers II participated in the study. Data were collected through a demographics questionnaire, a TPACK diagram, an open-ended questionnaire, interviews, and observations. During the study, feedba...

This study examined the connections elementary preservice science teachers made among various aspects of nature of science (NOS). Totally, 45 preservice science teachers who were enrolled in the Laboratory Application in Science II course participated in the study. The course provided meaningful and practical inquiry-based experiences, as well as explicit and reflective instruction about NOS. Each week, instructors targeted a specific NOS aspect related to the laboratory investigation. The desig...
