Abstract: It is aimed to investigate the effect of robotic-assisted practices in the teaching of renewable energy sources to science teacher candidates. Research was carried out with 20 volunteer teacher candidates who study at Artvin Çoruh University Faculty of Education in third grade of Science Teacher Education Program. A single group pre-test, post-test model was used in the study. The subject of renewable energy sources was tried to be taught to teacher candidates using the Lego® Mindstorms EV3 Training Kit and the Lego® Renewable Energy Kit. The practice lasted total of 20 hours in 3 stages. At the first stage, Lego® Mindstorms EV3 Training Kit and Lego® Renewable Energy Kit were introduced to teacher candidates. At the second stage of the practice, solar energy related materials and at the final stage of the practice, materials related to wind energy were ensured to be designed by them, and it was made them to do activities. In the research, as a mean of collecting data, "Attitude Test for Renewable Energy Sources" developed by Güneş, Alat and Gözüm (2013) in order to determine the attitudes of teacher candidates about renewable energy sources, "Renewable Energy Awareness Scale" developed by Morgil et al. (2006) and was translated into Turkish by Tiftikçi (2014) in order to measure the attitudes of teacher candidates about renewable energy sources and semi-structured interview form were used in order to determine the opinions and suggestions of the teacher candidates about the robotically assisted practice. The data obtained in the study were evaluated through the SPSS package program. In the light of this study, attitudes and awareness of teacher candidates concerning the renewable energy sources and how they perceive education with legos as a method were determined.
