This study mainly aims to examine digital learning material development self-efficacy, self-efficacy perception for technology integration, and educational technology standards self-efficacy from pre-service science teachers. Furthermore, the perspectives of pre-service science teachers on the use of DILMs created with the applications provided during the research the learning environment have been determined. The study was conducted with 53 pre-service science teachers studying at the education faculty of public universities in Turkey. As a data collection tool; "Self-Efficacy Scale of Teachers' Digital Teaching Material Development (DTeM)"), "Technology Integration Self-Efficacy Scale (TIn)", and "Education Technology Standards Self-Efficacy Scale (ETS)" were used. Besides, as data collection tool reflection reports were used too. The quantitative data were examined using the SPSS statistics package program, and the qualitative data were assessed using the content analysis approach. According to the study's findings, there was a statistically significant rise in the average scores of the pre-service teachers obtained from the scales of DTeM, TIn, and ETS in favor of the post-test. In addition, pre-service science teachers have positive opinions on the use of DILMs in the learning environment under the student, learning environment, and learning process category. The researchers finally suggest that such activities must be designed and organized not only for pre-service teachers but also for learners of this century.
