This research aims to study the impact of mobile learning on developing the skills of integrated science processes among the students of the optimal investment diploma at Najran University. The current research relied on the experimental approach with quasi-experimental designs by applying it to (60) students in the "Computer Science Curriculum" course, provided by the Department of Curricula and Teaching Methods at the College of Education. The students were randomly distributed into two groups (experimental and control), each of which consisted of (30) students. The mobile application service was used in the Blackboard system by downloading an electronic copy of the course content on this system for the students of the experimental group. A printed copy of the course content was also handed over to the students of the control group at the first meeting. Data was collected through a product evaluation card consisting of five domains, namely procedural definition, variable identification and control, hypothesis formulation, experimentation, and results interpretation. The results showed that the skills of integrative science operations among the participants in the experimental group (which received learning through mobile) were better than the skills of their colleagues in the control group (which received learning through the traditional method). In light of these findings, the study concludes that mobile learning can have interesting benefits for research and development of learners' integrative science processes skills.
