“…Science fairs promote interest in science (Vazquez, France and Perkins, 1994), promote enthusiasm about science, benefit students about communication and scientific skills (Fisanick, 2010), give students the opportunity to interact with other students interested in science (Grote, 1995), increase in students' attitude towards science course (Yıldırım and Şensoy, 2016), help the students to think critically (Tortop, 2014). There are negative effects besides positive effects especially in the literature due to the competition environment of science fairs in particular (Wang and Yang, 2003), dishonesty (Tortop, 2013b), apprehension (Fisanick, 2010) and cheating in science fairs (Syer and Shore, 2001). The participant students did not mention a negative effect in this study.…”
