Abstract: In this study, it was aimed to determine views of middle school students, preservice science teachers and science teachers about robotic applications. This study aims to present views and knowledge levels of middle school students, preservice science teachers and science teachers about robotic applications. In the study one group pretest-posttest experimental design was used. The study group of study consists of a total of 60 people including 20 middle school students, 20 preservice science teachers and 20 science teachers. In the study, the “Robotics Pre-Test”, which was developed by Riberio (2006) and translated into Turkish by Koç Şenol (2012), as well as "Robotics Satisfaction Test", which was developed by Silva (2008) and Gibbon (2007) and translated into Turkish by Koç Şenol (2012), and “Personal Information form" and a semi-structured interview form developed by the researcher after reviewing the relevant literature were used to collect the data. The study lasted for 60 hours in 3 stages. Middle school students were trained about robotics in the first stage, preservice science teachers were trained in the second stage and science teachers were trained in the third stage, respectively. In the first stage of the study, the Robotics and Lego Mindstorms Education EV3 Training Kits that will be used in the activities were introduced along with presentations and videos to the participants; in the second stage, they were informed about the use of Robotics program interface; and in the last stage, they designed a sample robot by using lego parts and performed some activities with programming. Descriptive statistics (frequency and percentage distribution) were used in the analysis of the data obtained from the study and inductive content analysis was applied in the analysis of the interview data. In the light of this study, views and knowledge levels of middle school students, preservice science teachers and science teachers about robotic applications as well as how they see the use of robotics as a method were determined.
