The activities of the students during the summer holidays, learning losses or the forgetfulness of the return of the holidays have been discussed in the educational sciences for a long time. However, very little research is being done and has little place in educational policies. This is especially important in applications and continuity courses such as coding and robotics. This is because out-of-school learning environments for skills that require this type of practice remain limited or not available to all students. The aim of this study is to determine whether secondary school students are doing any learning activities during the summer holidays for the subjects of Information Technologies and Software (ITS) and to determine whether there are learning losses during the summer holiday return. For this purpose, a working group was formed with 5th and 6th grade students. For the determination of summer holiday activities, interview form and knowledge test for the determination of forgetfulness were developed and applied to students before and during the holiday return. According to the results of the research, it is seen that middle school students perform many out-of-school activities for ITS during the summer holidays. Coding and robotics are at the top of the topics. It was determined that the most block-based coding activities were among the activities. When the levels of forgetfulness are addressed, it was seen that there was no learning loss.
