In this research, the effects of individual and teamwork activities on perceptions of block-based programming self-efficacy and attitudes towards robotic programming tried to be determined. The research has conducted in a private school located in Sariyer, district of Istanbul province in the 2nd academic year of 2018-2019 with 32 students from 7th Grade. The study fulfilled a semi-experimental pattern on the teamwork and individual work groups using the pretest-posttest design. The individual group consists of nine females (56.3%) and seven males (43.8%) and the teamwork group consists of eight females (50%), eight males (50%) students. According to the research results, individual work and teamwork did not affect secondary school students' perceptions of block-based programming self-efficacy and their attitudes towards robotic programming. In addition to this, it has been determined that there was a significant difference in attitudes of block-based programming self-efficacy perceptions and robotic programming for both individual and teamwork group students.
